Hospital Staff Cuts and its impact on hospital cleaning

Healthcare-associated infections (HAIs) are one of the biggest risks in healthcare today and Canada is no exception to this. In fact, Canada has one of the highest occurrences of HAIs out of all developed nations, with 200,000 cases per year and consequently, 8000 deaths (Statistics Canada, 2016). The spread of HAIs can be prevented, as we have seen on this blog, with proper handwashing techniques as well as proper disinfection protocols for equipment and patient rooms. The problem is that hospitals need A LOT of staff in order to properly disinfect, and control and prevent infection. And yet, Canada, as well as other countries, are seeing cuts in hospital staff.

According to a report prepared by Venrock (2018), one of the predictions for trends in healthcare for 2018 was the continuation of cutting and hiring less hospital staff. This is mostly due to hospitals working to balance their budgets. But at what costs does this balancing of budgets come at?

Although not a recent report, CBC’s Marketplace investigation of hospital cleanliness from 2012 does a good job at showing the consequences of hospital staff cuts (see video below). They interviewed nurses, doctors and hospital cleaners to find out more about staff cuts and its relation to infection control.

One hospital cleaner described the following:

“They’ve really cut staff, and we don’t have a lot of time to actually get done what we’re supposed to get done in a day. We used to have one person to one wing of the hospital to clean, but now we have three floors to clean.”

Anonymous, Hospital Cleaner (2012)

According to the report, in order to sufficiently clean a hospital room, it would take just over an hour. However, with the staff cuts being made, hospital cleaners are only getting on average 15 minutes for each room. This leads to a lot of uncleaned surfaces, leaving harmful pathogens in patient rooms. Furthermore, sometimes the harmful bacteria will even be spread from one room to another, since cleaners either don’t have the time to change cleaning materials or there aren’t enough cleaning materials. One example given in the report is that a cleaner will mop a patient’s room and then continue mopping into another room with the same water, simply because they don’t have the time to change the water.

Hospital staff cuts may save hospitals money, however, the potential risks that result from staff cuts are very significant and should not be overlooked. Leaving surfaces infected by pathogens can be detrimental to both patients and staff, and that is why it is essential to have an adequate number of educated staff to control the spread of infection.

Is Ultraviolet disinfection the new technology for reducing the risk of hospital-acquired infections?

According to a study published in the American Journal of Infection Control, the use of ultraviolet (UV) disinfection technology in an operating room eliminated up to 97.7% of pathogens (infectious agent), which otherwise could have caused hospital-acquired infections. The UV light technology that was used is by PurpleSun, a New York based company. PurpleSun’s UV technology can reach and clean multiple surfaces in several seconds, compared to traditional disinfecting methods which use chemicals and does not eliminate bacteria as well. Traditional methods also take longer, since it is normally humans cleaning with a disinfectant.

What is ultraviolet disinfection?

Ultraviolet disinfection is the use of UV light to disinfect. UV light is absorbed by the DNA and RNA of microorganisms, which in turn causes changes in the structure of the DNA and RNA. This makes the microorganisms incapable of replicating. According to Bolton (2008), “because they cannot multiply, they cannot cause disease, even though technically they are still metabolically alive.” Ultraviolet disinfection is more commonly used for the disinfection of water, however, it may soon become an effective method to eliminate bacteria causing hospital-acquired infections.

PurpleSun: pioneer in ultraviolet disinfection technologies?

PurpleSun is a New York based company, and is set to be the first company to launch ultraviolet-based technology as a disinfectant. Their mission, as stated on their website, is to reduce hospital-acquired infections, in order to save lives, reduce costs, and enhance safety in healthcare facilities.

On their website, they have identified 3 limitations with hospitals’ current disinfection process:
1) Everything is done by hand
2) There are thousands of surfaces, and not enough time to clean them all
3) There is no room for human error

PurpleSun’s light disinfectant will allow rooms to be cleaned within seconds, disinfect all the surfaces in the room and has been proven to be very effective in eliminating harmful pathogens.

Is ultraviolet technology the next step that healthcare facilities must take to reduce the risk of HAIs?

Light technology as a disinfectant is still in the process of experimentation in healthcare facilities. That being said, the study conducted produced highly favorable results. PurpleSun as a company has also been doing extremely well on a global scale, being named one of the 50 most promising companies in the world. Furthermore, many firms and organizations have been investing in and partnering with the company, demonstrating that the company has a lot of potential. The effectiveness of ultraviolet light as a disinfectant is undeniable, but for now, we will just have to wait and see what the future holds for it in healthcare facilities.

One-wipe cleaning system in hospitals proven to be effective

Source: Flickr

According to Infection Control Today (2018), a recent study carried out in a hospital in the UK has determined that a “one wipe” cleaning system was proven to be more effective than the traditional “two wipes” system in reducing the risk of MRSA in hospitals. Between 2013-2016, the hospital had been using a “two wipe” system, which consisted of first using a detergent wipe and then using an alcohol wipe as a disinfectant. In May 2016, a universal cleaning and disinfection wipe was introduced to the healthcare facility, and it made a significant difference.

According to Infection Control Today (2018),

“Using a Poisson model the researchers demonstrated that the average hospital acquisition rate of MRSA/100,000 patient bed days reduced by 6.3 percent per month after the introduction of the new universal wipe.”

Infection Control Today (2018)

These results were significant, and led to a big change in how this UK healthcare facility cleans its equipment. Not only did the universal disinfectant wipes lead to higher efficacy, but they also led to higher efficiency, since healthcare workers now only have to go over the equipment once and are assured that it will be clean.

Keeping this in mind, there are many different types of disinfectant wipes to choose from.

Hospital floors, yet another source of Hospital-Acquired Infections

The list of potential areas of contamination in hospitals seems to keep growing, leading us to identify more sources of hospital-acquired infections (HAIs) and making hospital cleaning continuously more complicated. To add to this, researchers are now finding that hospital floors are a significant source of hospital-acquired infections. Every day, hospital and clinic floors are flooded by thousands of people. Shoes soles, wheels from equipment, such as monitors or stretchers and bodily fluids all contribute to the contamination of hospital floors.

It seems so obvious; floors are dirty in general. Hospital floors must be even dirtier. However, as Koganti, et. al. (2016) describes,

“… hospital floors are often heavily contaminated but are not considered an important source for pathogen dissemination because they are rarely touched. However, floors are frequently contacted by objects that are subsequently touched by hands (e.g., shoes, socks, slippers). In addition, it is not uncommon for high-touch objects such as call buttons and blood pressure cuffs to be in contact with the floor.”

(Koganti, et. al. (2016).

In addition to this, shoe soles and wheels on equipment also frequently touch hospital floors. Shoes of healthcare professionals can lead to the spread of infection since these workers are visiting many different patient rooms. Similarly, equipment such as monitors, stretchers or infusion pumps all have wheels which touch the floors of multiple hospital rooms.

Now you might be thinking, ‘but surely hospital floors are routinely cleaned?’ While that is true, researchers are now finding that much of the floor cleaning that is done is relatively ineffective since the bacteria is able to reproduce so quickly. So, what can be done to help reduce the risk of hospital floor contamination?

A good hygiene program for hospital floors, to reduce the risk of contamination

The cleaning and the disinfection of floors are essential elements of an effective hygiene program for hospitals. Regular floor maintenance implies the systematic elimination of hidden bacterias, which can be achieved by using vacuums, mopping and other elimination processes.

A good floor disinfection program consists of using effective disinfectants/detergents and procedures that are notable for reducing the risk of contamination. It is also important that cleaning equipment be properly cleaned and maintained, so that bacteria doesn’t spread when cleaning.

Cleaning hospital floors seems like a daunting task, especially since bacteria has been able to reproduce and spread itself so quickly. Healthcare facilities will need to become more exigent with their floor cleaning programs, if they are going to seriously tackle the threat of hospital-acquired infections.

How to Prevent Cross-Contamination

Our last post discussed how janitors may contribute to the cross-contamination of different environments. As a follow up, this post will discuss different methods for preventing cross-contamination.

Cross-contamination can happen so easily that many people do not even realize it. A simple example would be that a janitor cleans a toilet with a wipe, and then uses that same wipe to clean the bathroom sink. Whichever viruses were present on that toilet have now been transmitted to the sink. This is why it is crucial that organizations develop cleaning programs that will prevent cross-contamination from happening.

Steps for preventing cross-contamination

Cleaning and Maintenance Management (CMM) makes three simple recommendations for the prevention of cross-contamination: (1) color code and categorize, (2) upgrade your tools, (3) clean from top to bottom. (2017).

The first recommendation is to color code and categorize. Organization is crucial in preventing cross-contamination. CMM recommends the use of a color-coded system, more specifically, the use of microfibre cloths and mop heads which come in a minimum of four colors: red, green, blue and yellow.
The British Institute of Cleaning Science recommends the following color chart for the cleaning of specific items and rooms:

  • Red: sanitary appliances, restroom floors, toilets, urinals
  • Yellow: restroom surfaces – sinks, towel dispensers, hand dryers, soap dispensers
  • Green: general food and bar cleanup in non-preparatory food areas, such as lunchrooms
  • Blue: areas of low-risk of contamination, such as hallways, offices and classrooms

Furthermore, it is recommended that cleaning tools are kept separate within the janitor’s closet. This is because if these items touch each other in the closet, then it defeats the purpose of having different colors for different areas and does not solve cross-contamination.

The second recommendation is to upgrade your tools. Having the best tools for cleaning will ensure that most of the bacteria is removed. Microfibre cloths and mops are highly recommended, since they are the best material for trapping dirt and bacteria. Once the dirt and bacteria are trapped in the microfibre, the particles will remain trapped in the material.

The third recommendation is to clean from top to bottom. Cleaning from top to bottom allows the cleaner to avoid missing any areas. By starting from the top, any dust or dirt that may fall to the bottom, or the floor, will be picked up afterwards, since the cleaner will then move on to the lower areas.

CMM provides the following methodological approach for top to bottom cleaning:

  • Wipe Down surfaces first. Make sure to wipe down surfaces before applying products.
  • Disinfect second. Spray disinfectant on areas that have been wiped down and let sit for 5-10 minutes before wiping it off.
  • Tackle the floor last. Mopping or vacuuming the floors last will ensure that anything that may have fallen onto it will be picked up.

Preventing cross-contamination may seem like a daunting task, but the steps recommended by CMM definitely help simplify it!

As you have read on this post, microfibre is one of the best cleaning tools that you can use because it has the ability to trap dust and dirt particles, and does not release them. Having microfibre cleaning products will provide you with optimal results in cleaning. Here at Lalema Inc, we offer all types of microfibre products. Feel free to consult our website for more details 🙂

How Janitors contribute to cross-contamination

Source: Wikimedia Commons

Janitors are responsible for the cleanliness and maintenance of many types of establishments, including hospitals, schools and restaurants. In most places, there are procedures and regulations to be followed in order to achieve optimal cleanliness and, ultimately, prevent the spread of harmful bacteria.

But did you know that janitors can also spread infection through cross-contamination, if there aren’t proper cleaning protocols in place?

According to Infection Control Today (2019),

“Cross-contamination is defined as the spread of germs from one surface or object to another and frequently occurs when performing janitorial tasks.”

Robert Shor, Infection Control Today, 2019

Infection Control Today describes several possible causes of janitorial cross-contamination, which include mop heads, towels, and gloves. While it is known that these sources are associated with the spread of infection, there is one which is often overlooked: the gloves worn by the janitor. While cleaning many different rooms, and even different buildings, the janitor usually keeps the same gloves for the duration of the cleaning. When changing rooms and buildings, he is spreading the bacteria that are on his gloves.

Infection Control Today suggests the following protocol for janitors’ use of gloves:

  • Don gloves before performing cleaning tasks (use gloves that are appropriate for the task being performed).
  • Change gloves in the following situations:
    • When they become soiled, torn or punctured
    • After cleaning areas with high concentrations of germs (restrooms)
    • When going from building to building or floor to floor
    • After cleaning each classroom (room), restrooms, kitchen areas
  • Avoid contaminating your hands when removing gloves by following CDC guidelines.
  • Wash hands and/or use hand sanitizers after janitorial tasks are completed.

Janitors play a very important role when it comes to keeping establishments sanitary and safe. That is why it is crucial to develop protocols to ensure the highest quality of cleaning.

Handwashing really is important…

February 2019. We have all learned time and time again about the importance of handwashing, and how it can reduce the risk for harmful infections and, ultimately, save lives. Then, along comes Pete Hegseth, co-host of Fox & Friends, with the statement that he has not washed his hands in 10 years. He stated the reason for this as being “germs are not a real thing – I can’t see them, therefore they’re not real.” Whether he was joking or not is still under debate, but one thing is for sure, his statement is far from being correct.

Hegseth’s statement no doubt created a lot of publicity, but many are now concerned that people will be influenced by him in not washing their hands. And they have every right to be.

The Guardian (2019) quotes Professor Val Curtis, from the London School of Hygiene and Tropical Medicine, where she states that:

“Hands are the most important vector of infectious diseases.”

Val Curtis, 2019. Retrieved from the Guardian

She adds to this that not washing your hands or improper handwashing puts everyone at risk, and that it is a moral issue above all. If, for example, you go to the washroom and don’t wash your hands, everything you touch afterwards will be contaminated. Everyone who touches the same surfaces that you did will be touching the bacteria that you have spread, putting them at high risk for infection.

Even though the risks are significant from improper handwashing, many people rarely put in the extra little effort needed in order to reduce these risks. According to Sandoz (2019), 1 in 20 people fail to wash their hands properly after using the washroom. Also, the average time that people take to wash their hands is 7 seconds, which is far below the recommended 20 seconds (Sandoz, 2019).

How to properly wash your hands

So what is considered proper handwashing and how can we achieve it in order to prevent infection? The Centre for Disease Control and Prevention (CDC) provides us with detailed steps in order to maintain ultimate hand hygiene. The steps are as follows:

  1. Wet your hands with clean, running water (warm or cold), turn off the tap and apply soap.
  2. Lather your hands by rubbing them together with soap. Be sure to lather the backs of your hands, between your fingers and under your nails.
  3. Scrub your hands for at least 20 seconds.
  4. Rinse your hands well, under clean, running water.
  5. Dry your hands using a clean towel or air dry them

Proper handwashing is necessary to prevent the spread of infection and to ultimately save lives. It doesn’t take a lot of time or effort to do, and it can make all the difference. So do your part for yourself and society; wash your hands 🙂

Candida auris : A new threat ?

Candida auris

After the coming of hospital’s contracted diseases such as C. difficile or MRSA (Methicilin-Resistant Staphylococcus Aureus), another difficult to treat bug seems to emerge. This time, it is a fungus: Candida auris.

This fungus or more precisely this yeast, has first been discovered by scientists in 1996. Then, a first infected human case has been reported in Japan in 2009. 1,2 To this date, Candida auris has been detected in hospitals of more than 20 countries such as the United States of America, England and many Europe countries. The first case in Canada has been reported in 20173.

Candida auris poses a specific threat because of the following characteristics4:

  • Infections by this microorganism have a high mortality rate.
  • The microorganism resists antifungal agents.
  • The microorganism is difficult to identify in clinical microbiology laboratories which results in wrong diagnostic. The identification is important in the choice of antifungal treatment.
  • The microorganism is known for its virulence.
  • The microorganism colonizes surfaces such as catheters used for healthcare.

Among recommended precautions by American and Canadian governments, disinfection of surfaces plays an important part. However, specific disinfectants are to avoid: this is notably the case for quaternary ammonium-based disinfectants which are ineffective5. The following procedure is rather recommended:

« Healthcare facilities that have patients with C. auris infection or colonization should ensure thorough daily and terminal cleaning and disinfection of these patient’s rooms with hospital-grade disinfectant effective against Clostridium difficile spores. »6

Sporicidal sodium hypochlorite-based disinfectant against C. difficile are for example great disinfectants to prevent and control contact transmission of Candida auris. In other words, scientists are only starting to understand and study this recently discovered microorganism. More studies will allow the discovery of effective treatment.

Until that time,in need of sporicidal products against C. Difficile to face Candidaauris new threat? Get our products right now!

Water, a source of hospital-acquired infections?

Hospital-acquired infections are a serious threat in healthcare facilities today and researchers keep finding new sources of these infections. We know that sources of HAIs include surfaces, high-touch objects, hands and medical devices, but did you know that these infections can also occur due to the water and plumbing systems in healthcare facilities?

Source: Public Domain Pictures

According to Infection Control Today (2018), “Potable and utility water systems in healthcare settings are reservoirs and vectors of Hospital-acquired infections, resulting in pneumonias, bacteremias, skin infections, surgical site infections, eye infections and others.”

Hospitals are major users of potable water, whether it be for drinking, bathing, hand-washing or rinsing medical devices. It is therefore important that healthcare facilities realize that the water entering their facilities is not considered sterile.

Why is the water in plumbing systems infected? The design of and water use patterns in premise plumbing creates biofilms, which provide shelter and food for harmful bacterias. According to Infection Control Today (2018), “Biofilms in premise plumbing systems are complex ecosystems, and it is within these biofilms that bacteria, fungi and amoeba find the food, water and shelter they need.” Many bacteria develop in the biofilms, such as Legionella, Ancinetobacter aumanniii, Aspergillus flavus, etc.

Legionella – what is it and how does it affect patients in a healthcare setting?

Legionella colonies

Legionella is one example of a bacteria that is found naturally in water. This bacteria is known for causing Legionnaires’ disease: a severe form of pneumonia. This disease is one of the most significant waterborne infections. Legionnaires normally has a mortality rate of only 10%, however, if acquired in a hospital, this rate goes up to anywhere between 25-50% (Infection Control Today, 2018)! Hospitals experience the highest number of outbreaks of Legionnaires disease (compared to other types of buildings) due to having a large number of patients with weakened immune systems or that have chronic diseases. It is important to note that the majority of Legionnaires cases in hospitals are due to the drinking water system.

How to reduce the risk of wHAIs: education and water management programs

So now that we are aware of waterborne hospital acquired infections (wHAIs), is there a way to reduce the risk that potable water poses to healthcare facilities? Infection Control Today (2018) suggests both education and water management programs as possible solutions to reducing the wHAI risk. Firstly, through education, it is important that healthcare workers know that potable water does carry bacteria and does cause an increase in HAIs. Second, once this idea of water carrying bacteria is understood, it will be important to implement water management programs. There can be no standardized water management programs, as all facilities differ in factors such as age of establishment and system, overall design of plumbing system, populations served, etc. Some hospitals have already tried different methods of water disinfection. Examples of these methods used to reduce risk include the use of sterile water in high-risk patient areas, engineering controls and point-of-use water filters.

To summarize, healthcare facilities must realize the risk that water and plumbing systems pose to their patients and employees. Hospital-acquired infections are one of the leading causes of death in North America and it is therefore crucial that hospitals take action against any source that could spread these infections. Education and water management programs are the best ways to help reduce the risk of wHAIs, according to Infection Control Today (2018).

Medical hygiene monitoring badges: how new technology is helping to prevent the spread of microorganisms

Hygiene and cleanliness are already monitored closely in hospitals and healthcare facilities. Hand sanitation is a crucial hygiene practice for both medical professionals’ well-being, as well as their patients. However, according to TrendHunter (2014), hand hygiene compliance in US hospitals is only achieved 50% of the time. And this is only an example of hand hygiene in the US. Studies would probably show similar, if not worse, percentages in countries across the globe. That is why Biovigil invented a medical hygiene monitoring badge.

Source: Pixabay

The Biovigil monitoring badge is specifically made for hand sanitation. The badge can be clipped on to a scrub or lab coat. It reminds healthcare workers to clean their hands when they leave or enter a patient’s room. It also works by telling either healthcare professionals or patients if their hands have been properly sanitized by turning green when the worker places their hand over the monitor. The badge also collects data on hand sanitation and sends it to be analyzed. While these badges are not heavily used yet, they could prove to be very efficient in eliminating the spread of hospital-aqcuired infections.

It is not, then, unreasonable to ask what other sort of technology could be developed in order to better monitor hygiene and sanitation in healthcare facilities. With the technological resources we have today, it is highly possible to create new products such as this. For now, most hygiene monitoring technologies revolve around hand sanitation. But as we’ve seen in other posts, there are way more sources of contamination and spread of bacteria than just hands; hospital bed mattresses, marked medical instruments, surface damages on medical equipment, etc. Why not create a technology that monitors the hygiene of these things as well? Similarly to the hand sanitation monitor, there could be monitors for other medical equipments that alert healthcare cleaners to check if they are clean and safe to use.

Global Market for antiseptics and disinfectants: Rapid Growth Expected

With the number of hospitals and healthcare facilities on the rise around the globe, more institutions and individuals are realizing the importance of antiseptics and disinfectants. According to Zion Market Research’s forecast, the global antiseptic and disinfectant market is expected to reach USD 8.1 billion by 2021 (market value of 5.55 billion in 2015), and is expected a rapid growth rate of about 6.7% yearly between 2016 and 2021.

WHAT IS THE DIFFERENCE BETWEEN ANTISEPTICS AND DISINFECTANTS?

Antiseptics and disinfectants are both fundamentally used for the same purpose: eliminating disease-causing organisms. How they differ, however, is based on the surface they are used on. Antiseptics are used to kill microorganisms on or in the skin. Disinfectants are used to get rid of microorganisms on the surface of objects or surfaces. (Livestrong, 2014).

WHY ARE THEY SO IMPORTANT?

Antiseptics and disinfectants are essential to preventing infection. Hospital acquired infections, caused by the spread of microorganisms, is one of the leading causes of death worldwide and is the fourth leading cause of death in Canada. Antiseptics and disinfectants are especially necessary in a healthcare setting, as preventing hospital-acquired infections can save lives, reduce a patient’s hospital stay time and save hospitals a lot of costs associated with these infections. With an increase in advanced healthcare facilities and medical professionals/researchers worldwide, antiseptics and disinfectants are increasingly in demand. It is also important to note that, as developing countries are modernizing their healthcare facilities, demand is increasingly high in these regions. Institutions make up the biggest segment of the demand for these products (50% of market), hospitals and schools being major consumers.

To conclude, increase in advanced technologies, research and healthcare facilities has contributed to a higher awareness (both institutionally and domestically) of the danger that bacteria poses if left on skin or surfaces. This increase in awareness is what is driving the market for antiseptics and disinfectants and leading to its rapid growth, which is expected to continue.

How certain medical instrument marking methods can enable the growth of microorganisms – and what to do about it

In order to make it easier to identify a medical instrument, many doctors use different marking systems.The methods in which medical instruments can be marked are quite strict, in order to prevent the spread of bacteria. For example, instruments cannot be engraved because bacteria can get stuck in the small holes and grow. The article “Instrument Marking Methods Must be Maintained Properly”, by Nancy Chobin, describes three different methods of marking medical instruments and how these methods still have disadvantages and need to be maintained.

First method for marking a medical instrument

Firstly, instruments are often marked by different colored tapes, however, many healthcare professionals fail to realize that the tape on the instruments can harbour bacteria and must be very carefully maintained. The tape should be replaced as soon as it begins to chip, as those small tears in the tape could allow for microorganisms to grow. According to Chobin “All tape and adhesive residues should be completely removed and the instrument washed before it is re-taped.” It is also stressed that a sharp object should not be used to remove tape, as this could simply create small fissures on the instrument where bacteria could grow.

Two other methods for marking a medical instrument

There are two other methods for marking instruments that are considered “acceptable”; chemical etching and color-bonding. These methods also come with some disadvantages, such as color-bonded instruments also chipping sometimes, however, seem to be more “sanitary” than using tape.

Why is this important? The general goal of healthcare facilities is to improve the health of its patients, while at the same time controlling and preventing the spread of infections and contamination. This means that healthcare facilities should aim to prevent, at all costs, the growth of bacteria. In order to be able to do so effectively, healthcare workers must know where all sources of bacteria may come from.

Infection control in schools

Every parent knows it: when kids are in school, they are way more likely to get sick than when they are not. From sharing toys, chairs, desks, computer keyboards, water fountains and door handles, kids are the most prone to getting sick. Elementary and preschool students are the most prone to getting sick at school, mostly because their immune system is not fully developed yet. On average, elementary students will have 12 colds per year (yikes!). And let’s not forget that many school staff also end up getting sick from their students. So what can be done to help stop the spread of infection among students and staff?

Source: Pixabay

Sure, you can remind kids to wash their hands, cover their mouths when they cough, etc, but how effective will it really be? Schools must play a very important role in the cleaning and disinfection within their buildings in order to protect both employees and students. The primary person responsible for the upkeep of the school building is the custodian, and, as such, he should be trained in infection control methods.

The Centers for Disease Control and Prevention (CDC) makes the following recommendations on how to properly clean and disinfect schools and what procedures to follow:

  1. Knowing the difference between cleaning, disinfecting and sanitizing
    The CDC stresses the difference between the three methods of “cleaning”. While cleaning involves the removal of dirt and germs, it does not necessarily kill the bacteria. Disinfection, on the other hand, uses chemicals to kill bacterias, and does not focus on a clean surface, but rather a bacteria-free one. Finally, sanitization is the process of lowering the number of bacteria to a safe level.
  2. Clean and disinfect surfaces that are touched often
    This point speaks for itself; many schools already have a specific procedure regarding what should be cleaned more often, such as desks, compared to something that does not have to be cleaned often.
  3. Do routine cleaning and disinfecting.
  4. Clean and disinfect correctly.
    It’s simple to say, however, many people and institutions are not trained to know exactly what “correctly” means. It is important to pay close attention to the detailed instructions provided on the label of product.
  5. Use products safely.
    Pay attention to warnings and hazards on the label of product. Make sure that proper equipment (gloves, masks, etc.) are used when necessary.
  6. Handle waste properly.
    Avoid touching tissues/napkins when emptying waste baskets. Wear gloves, if possible. Wash hands after handling waste.
  7. Learn more.
    CDC provides more follow up information on their website about disinfection and cleaning for schools.

Let’s prevent staff and students from getting unnecessary illnesses and work together for a more clean and safe learning environment!

Surface Damage and its implications for healthcare facilities

Preventing and controlling the spread of contamination and infection is of very high importance for healthcare facilities, and it is safe to say that many measures have already been taken in order to reach these goals. However, like many things, there is still much room for improvement moreover when it is about surface damage.

medical equipment surface damage

Source: Shaw Air Force Base

Evidently healthcare facilities use a wide variety of equipment, from monitors to surgical instruments to cleaning tools, and over time, this equipment wears down. Sometimes, equipment will break completely and be unusable, however sometimes there will only be a few scratches or other small damage.  But what happens when these scratches or other forms of damage become shelters and areas of growth for microorganisms? This is an example of how surface damage may not only impede the prevention of bacteria growth, but also provide the microorganisms with a place to grow.

What is surface damage?

According to Infection Control Today, surface damage is defined as:

a quantifiable physical or chemical change from the original manufactured state of an object (surface or device).

While it is recognized that surface damage of medical equipment poses a potential threat in the spread of bacteria in healthcare facilities, there is no standardized method for healthcare workers to determine what is considered surface damage, and at what point the damage is likely to cause the spread of bacteria. In a later blog post, I will discuss the ideal surface damage testing protocol, proposed by Peter Teska et al. in “Infection Control Today.” In this article, the authors discuss ideal methods of avoiding the problems that surface damage presents.

Hospital bed mattresses: An overlooked healthcare hazard (Follow up)

As a follow-up to my previous blog post about the problem of hospital bed mattresses being contaminated, I would like to go into further detail the recommendations provided by the Food and Drug Administration (FDA). As previously mentioned, the FDA recommends that healthcare facilities take preventative measures against contamination of hospital bed mattresses in four simple steps: inspection, removal and replacement, maintenance and the development of an inspection plan.

Hospital bed matressesSource: Flickr

Inspection involves routinely checking the bed mattress cover for any signs of damage, stains or tears, as well as checking if the bed mattress cover is past its expiry date (Yes – bed covers do have a limited lifespan). It is also important to frequently remove the cover and check the inside surface, as well the mattress itself for these same conditions.

Next, it is important to replace any mattress covers with visible signs of damage or stains. Also, mattresses with damage or visible stains should be removed immediately.

For maintenance, it is important to clean and disinfect undamaged bed mattress covers. This can be done according to the bed cover cleaning guidelines given by the manufacturer.

Finally, FDA suggests that healthcare facilities develop an inspection plan that can be applied for all medical bed mattresses and covers. It is important to check the expected life of the bed mattress, as well as the cover.

Hospital bed mattresses: An overlooked healthcare hazard

Hospital beds are composed of many different parts: the bed frame, which includes the bed side rails, as well as a mattress and a mattress cover. Once a patient is discharged from the hospital, normally, the room will go through a substantial amount of cleaning, including the bed. The rails and bed frame will be wiped down and the bed cover will be changed in order to prepare for the next patient. However, one factor is often dismissed: the hospital bed mattress.

According to the ECRI Institute:

Bed and stretcher mattresses can remain contaminated after cleaning, putting patients and staff at risk of exposure to body fluids or microbiological contaminants. Reported incidents include patients lying on an apparently clean bed or stretcher when blood from a previous patient oozed out of the support surface onto the patient.

While hospital bed covers are changed regularly, many health care facilities fail to examine these bed covers for damages, heavy stains or tears. It is also important to note that mattress covers have an expected lifespan, and will become ineffective after this duration of time. All of these factors can lead to blood or any other body fluids leaking onto the hospital bed mattress, therefore leaving it contaminated.

The FDA (Food and Drug Administration) makes several recommendations in order to overcome this healthcare hazard:

  • Inspect
  • Remove and Replace
  • Maintain
  • Develop an Inspection Plan

While companies who sell the mattress covers have the responsibility in properly explaining to healthcare facilities how to properly disinfect, clean and dispose of bed covers, it is crucial for healthcare facilities to use the necessary materials and procedures in order to clean and disinfect. Healthcare facilities must also regularly inspect both mattress covers and mattresses in order to prevent infection as much as possible.

Towards a universal vaccine against flu

Influenza is a stubborn virus. Moreover, every year, the virus is changing and it’s another race against time to produce a new vaccine, often composed of several strains, which will be able to protect the most vulnerable population such as young children, the elderly and sick people.

inlfuenza

AN ENCOURAGING RESEARCH on INFLUENZA

According to the article by Radio-Canada:

At Laval University, Gary Kobinger’s team is testing a new influenza vaccine, which could provide better protection and long-term immunization. The formula incorporates much of the circulating influenza strains over the last 20 years.

A first clinical trial to test the safety of the vaccine ended a few months ago. According to the researchers, it shows that the product does not cause significant side effects.

The effectiveness of vaccines against influenza (the flu) is also limited especially when we guess wrong the strain that will be the most virulent that year!

THE IMPORTANCE OF HAND WASH

We are all at one point exposed to the flu virus. A good way of individual prevention is to put on your hat on and tie your coat. I am joking. On the other hand, regular hand washing before meals, after the toilet and even just when arriving at work or at home is really an effective way against the spread of the virus.

Regular hand soaps like Utopia or antibacterial soap like Utopia AB do the trick.

Did you know that our soaps do not contain any: methyisothiazolinone?

THE IMPORTANCE OF SURFACE DISINFECTION

Cleaning worker also plays a very important role in the winter period when it comes to disinfecting surfaces. Specialty products such as the Ali-Flex line of product offers many benefits:

Would we be ready to face an epidemic of bubonic plague?

Would we be ready to face an epidemic of bubonic plague?

In Madagascar, the government has recently imposed two days ago new emergency measures to stop a plague epidemic. It has been declared 24 dead since 1 month1.

black_death

What is the bubonic plague?

The plague is a bacterium Yersinia pestis, present in rodents as rats are often passed to humans by infected fleas.

According to Health Canada:

The incubation period of the plague varies from one to ten days.

Whatever the form, the illness always starts with flu-like symptoms (fever, chills, muscle aches, weakness and headaches) and can also cause nausea, vomiting, diarrhea and abdominal pain.

If left untreated, the mortality rate can reach 50%.

SURFACES DISINFECTIONS

According to Health Canada2, in the event of a spill or contaminated surfaces:

Let the aerosols fall; wear protective clothing, carefully cover the spilled material with paper towels and apply 1% sodium hypochlorite from the periphery to the center; allow to act for a sufficient period (30 minutes) before cleaning

Plague is affected by many types of surface disinfectants such as:

MATERIAL SAFETY DATA SHEET: PATHOGENIC AGENTS, AND RISK ASSESSMENT

You are dealing with a bacterium, virus or other pathogen and you want to know more about it. Health Canada has launched an application and a website:

LAST CASE REPORTED IN CANADA

Cases of plague in humans are very rare in Canada; the last case was reported in 1939.

How to reduce the phenomenon of antibiotic resistance?

As you know, improper and inappropriate use of antibiotics has resulted in bacteria developing resistance mechanisms. In general, we observe a decrease in the effectiveness of antibiotics in fighting multiresistant bacteria. In fact, the antibiotics that were developed between 1940 and 1980 generally had a very specific target, which facilitated the acquisition of resistance mechanisms by bacteria. In addition, the new antibiotics that are marketed are generally similar to existing antibiotics, making resistance acquisition even easier for bacteria. Thus, all the preceding facts suggest the importance of developing new antibiotics displaying novel mechanisms of action.

One of the alternatives is to develop antibiotics targeting the cell membrane of bacteria. Among others, we find the natural antimicrobial peptides that are a class of molecules participating in the immune response of several organisms such as bacteria, plants and mammals [1]. These peptides have the ability to form pores or to induce defects in the cell membrane, which will lead to a disturbance of the electrochemical gradient across the membrane, thus causing cell death (FIG. 1) .

antibiotic-resistance

Figure 1: Illustration of the main mechanisms of cationic antimicrobial peptides [3].

Inspired by these natural peptides, many researchers are attempting to develop synthetic antimicrobial peptides that will be both less toxic and pharmacologically viable. On the market, we find daptomycin (Cubicin®) which acts by a mechanism similar to natural antimicrobial peptides [4]. This antibiotic from the lipopeptide family is used for the treatment of infections involving methicillin-resistant Staphylococcus aureus (MRSA). It is interesting to note that, like natural antimicrobial peptides, quaternary ammoniums, which are commonly used in disinfection operations, also destroy bacteria because of their membrane activity [5]. At Lalema, a wide range of quaternary ammonium-based disinfectants are available to meet your needs.

The ever-growing problem of antibiotic resistance is a major health issue and a heavy tax burden on governments. The use of an adequate antibiotic management system, the advent of new technology and better control of the transmission of pathogens (disinfection) are essential tools to reverse the current trend.

The complete guide to hospital cleaning

hospital-cleaning

For a long time, cleaning has been all about the look; fresh smell and the absence of stains or dirt were the criteria to determine that a place is clean. Today, these criteria are still generally accepted in environments such as offices and classrooms.

It’s common knowledge, however, that microbes (bacteria or viruses) invisible to the human eye represent a risk for spreading infections. Take the example of the influenza virus: it can survive for up to 48 hours on a hard surface!

Without cleaning and disinfection procedures or a quality check procedure, microbes can survive in hospital environments.

Three key elements have to be considered in order to perform an infective risk analysis:

  • Is the patient carrying a disease agent? Disease agents are classified based on their spreading capacity and their virulence. The choice of a disinfectant will be based on this.
  • Do the functional activities of a sector represent a risk of spreading infections from the environment? E.g.: food service, offices, Intensive Care, etc.
  • The intensity of contact is related to the traffic and the surfaces that are more likely to be touched. E.g.: bathroom fittings.

Infective Risk Analysis

Cleaning in hospitals allows reducing risks of infection among patients. This is not the only factor, of course: good personal hygiene habits such as washing hands and the use of protective equipment such as overalls, gloves, masks, or protective glasses are also important elements.

For this reason, interventions must be well coordinated in order to have a good surface maintenance plan. The manager of hygiene and cleanliness should therefore take into account:

  • The type of place associated to the level of risk
  • The tasks to perform
  • The required cleaning frequency

If well applied, a detailed estimate allows validating the cleaning performance.

The global approach is going to be determined by type of place:

  • Regular eradication (e.g.: operating rooms)
  • Keeping environmental effects as light as possible (e.g.: low infection risk such as individual office spaces)
  • Balance of microorganisms. This approach is based on the competition between good and bad microbes. The presence of good microbes guarantees less space for bad microbes to grow (e.g.: living environments)
  • Green cleaning. Approach that uses less toxic products
  • Review and improve arrangements and/or surfaces (during conception or renovation)

The Cleaning Staff: key to success

The hygiene and cleanliness staff represents a key element in the fight against infections in hospital environments. Often little valued, their role in the global strategy of surface cleaning is extremely important.

The hygiene that comes from the work of the cleaning staff requires a high performance level. In order to reach that, the executing staff and the managers need to master all the different elements representing this profession.

Cleaning products and equipment are undeniably crucial in order to ensure performance during the environment asepsis of any establishment. Therefore, it is important to associate the day-to-day actions of the cleaning staff with a range of products and equipment that favor the quality of their performance.

Since several years, partly due to the devotion and the involvement of many members in the healthcare system, we take into consideration new factors:

  • Provincial training
  • Establishment of an AEP hygiene and cleanliness in healthcare environments of 630 hours now offered by many school boards
  • Provincial day of hygiene and cleanliness
  • Etc.

Having said this, the hygiene and cleanliness staff deserves our deepest gratitude. Thank you so much!

Work Organization

How can proper work organization contribute to the cleanliness of a hospital? How to be in the right place with the right equipment? Here are the questions we are going to answer in this post of the Cleaning in Hospitals series.

Evaluation of production needs

First, we need to assess the needs in hygiene and cleanliness. In order to do this, a standard evaluation is preferable but it needs to be adjusted based on the type of place, units, and traffic.

It is during the evaluation of needs that the hygiene and cleanliness estimate (see Cleaning in Hospitals part 2) is going to be determined. All daily, weekly, monthly, and annual tasks have to be considered.

Usually, the results are presented by production yields (square meters/hour) or FTE (Full Time Equivalent).

How to reduce time waste

How to measure productivity in a context where an important aspect of the task is moving? Actually, hygiene and cleanliness departments are almost always in the basement, whereas most of their work happens on the floors!

We increase productivity by reducing traveling.

It is for this reason that the cleaning cart needs to be as complete as possible and the water sources or janitor’s closets well stocked with supplies (i.e.: paper products or waste bags), equipment, and sanitary products.

Moreover, it is important to remember that a good entrance carpet can greatly reduce dirt.

Have a successful day!

Here are a few hints on how to have a successful day:

  • Establish a sequence of actions to perform in a day/week/month
  • Define a sequential order of rooms
  • Integrate linked and periodical tasks (monthly)
  • Make sure to have time gaps to focus on periodical tasks (dusting of high surfaces, polishing, etc.)
  • Minimize traveling
  • Work by space and not by task
  • Distribute tasks equitably
  • One look is worth a thousand words: choose a colorful plan together with some graphics instead of a list of tasks on a word file!

An enzyme to destroy biofilms

One can not stop the progress. The discovery of an enzyme capable of preventing the production of a biofilm, this polymeric protective layer produced by bacteria that prevents antibiotics and surface disinfectants from functioning well, could ultimately revolutionize the fight against nosocomial infections.

perturbation-biofilm

The team at the McGill University Health Center, which includes Dr. Donald C. Sheppard, has published a study in the journal Proceedings of the National Academy of Sciences (PNAS). Their hope is that this technology will be the subject of human clinical trials in Canada within 5 years and be used in hospitals within 10 years.

From the abstract:

We demonstrate that glycoside hydrolases derived from the opportunistic fungus Aspergillus fumigatus and Gram-negative bacterium Pseudomonas aeruginosa can be exploited to disrupt preformed fungal biofilms and reduce virulence.

What is a biofilm?

My colleague RĂ©mi Charlebois described biofilms as follows:

Biofilms found on surfaces are often derived from a complex colony of microorganisms producing polymers that allow them to adhere better to the surface and facilitate colony life. In short, a biofilm is like a city for microbes. Man has learned to tame these biofilms and can use them to treat wastewater or produce certain molecules such as natural plastics. However, the presence of unwanted biofilms could be harmful and can lead to infections.

Biofilms are also found on the skin and medical devices. Thus, according to the article of Le Devoir:

Biofilms, a highly sticky matrix of proteins and sugar polymers made by bacteria to protect themselves, are attached to the skin, mucous membranes or the surface of biomedical materials, including catheters, tubing, heart valves and other prostheses Which become preferred entry points for infection.

In the same article, Dr. Sheppard quotes:

Biofilms are produced by molecules that defend against our immune system or against antibiotics with this shell that is 1000 times more resistant than the organisms that produce and proliferate in these biofilms.

An enzyme that acts as a “destructive machine” for biofilms

In short, the enzyme discovered was modified to destroy the biofilms instead of forming them. This is a new strategy that can reduce nosocomial infections in healthcare centers.

What about Surface Disinfection against Poliovirus

Recently, my friend RĂ©mi wrote on Twitter: “Why is it so long to get rid of Polio in the world? “, Did you know that there are barely 30 cases per year in the world! Only 3 countries in the world still have Polio cases. One of these 3 countries, Nigeria is on track to succeed with no cases reported since 1 year.

Should we worry about the anti-vaccine movement?

In the report on CNN twitted by RĂ©mi, the specialist mentions that the number of children not vaccinated in the United States is growing continuously. Will we have to wait for another epidemic?

Surface disinfection against poliovirus type 1

According to Health Canada, in its guideline – Safety and Efficacy Requirements for Disinfectants Assimilated to Hard Surface Drugs, a broad spectrum virus is defined as:

Broad-Spectrum Virucide: A disinfectant that is shown to be effective against a representative, envelope-free and hard-to-kill virus, which is also intended to inactivate other enveloped and envelope-free viruses (ie a product of which A “broad spectrum virucide” efficacy has been demonstrated).

Also according to Health Canada:

The incidence of poliomyelitis in Canada declined following the creation of vaccination programs in the 1950s. The last indigenous case of wild poliovirus infection in Canada dates back to 1977. In 1994, the World Health Organization Officially declared Canada free from wild poliovirus. The cases of paralytic poliomyelitis that have occurred in Canada since then have been associated with imported cases of wild poliovirus infection and the use of OPV.

According to the MSSS, in its guide “Disinfectants and disinfection in hygiene and sanitation: fundamental principles”

Among the viruses are those that are enveloped by a lipid layer and those that are not. These are called naked viruses. Paradoxically, this lipid-rich envelope is easily altered by chemicals, making wrapped viruses vulnerable. In contrast, naked viruses are “accustomed” to coping with outdoor conditions and are more resistant to disinfectants. Generally, if a disinfectant is active against naked viruses, such as polio, it is likely to be active against enveloped viruses, such as AIDS (HIV).

Quaternary or sodium hypochlorite disinfectants

Quaternary or sodium hypochlorite disinfectants with the “broad-spectrum virucidal” claim are effective against naked viruses such as polio.

Inside an anthill near you

Several tasks accomplished by ants are similar to those of human professions such as farmer or breeder. Swiss researchers recently added a surprising task to this list: chemist!

Community life

We all know that anthills are full of ants. A population of a colony can easily reach several millions. Although they may be insects, food supply, waste management and infection control are, believe it or not, a major concern for the queen of an anthill.

The chemist ant

By mixing coniferous resin with formic acid (a venom secreted by ants to combat their enemies), the mixture doubles the antifungal efficacy of the resin alone. These ants are capable of improving the resistance of the colony to pathogens. This is the first time that we have observed, apart from humans, a species mixing different compounds in order to improve their effects.

Hard surface Disinfection in the human world

At Lalema, conifer resin and formic acid are not used to make our disinfectants. On the other hand, our formulas are developed and validated by real chemists in addition to being registered with the appropriate governmental bodies.

Biofilms: What you should know.

Biofilms are everywhere

Well hidden or sometimes visible, always disgusting, biofilms, as so well described by my colleague RĂ©mi Charlebois, are defined as follows:

Biofilm is an aggregation of microbial cells, surrounded by a protective layer of extracellular polymeric matrix, which attaches itself to any surface found in the hospital environment and becomes a source of contamination. Formation of complex, multicellular communities by microorganisms is a natural phenomenon which helps bacteria or fungi to survive environmental stress such as cleaning and disinfection.

How to remove biofilms

Here are 3 methods to eliminate biofilm:

Replace equipment

This mehode is somewhat drastic, probably very expensive certainly mostly impractical. Some industries still proceed that way in 2016. I must say that in some cases it may be the only and best solution. For example pipe sections, filters, etc.

Strong acids and bases

Hydrochloric or Peracetic acids or strong bases such as caustic are sometimes used alternatively. However, corrosivity and danger of these chemicals can damage surfaces, individual protection equipment, storage and handling can also be a challenge . Furthermore, there is always the workplace hazards.

3 useful definitions in cleaning and disinfection

When it comes to cleanliness, some people are mixing technical terms leading to ambiguity. It is like mixing chemicals together: That is not a good idea! To keep it simple, we’ll just give three useful definitions.

Deteriorated surfaces

A deteriorated surface shows wear off sign often caused by time or misuse.

Deterioration is one of three elements of impairment of property, the others being functional obsolescence (or obsolescence) and economic obsolescence.

surfaces-vetustes

Safe surfaces

Safe surface means that it is safe to health. Such surface is healthy or good for health often because of risk management. In the food industry, this is why we often refer to it as food safety.
Safe is also synonymous to hygienic !

corridor-hopital-lalema

Disinfected surfaces

Disinfection is a voluntary momentary removal operation of certain bacteria (if it comes to “all germs” we refer more to sterilization), so as to stop or prevent infection or the risk of infection or superinfection by pathogenic or undesirable microorganisms or viruses.

For example:

  • To sanitize a surface eliminates 99.9% of microorganisms (This is a 1,000 X reduction)
  • To disinfect a surface removes 99.999% of microorganisms (This is a 100,000 X reduction)
  • To sterilize a surface or instrument removes 99.9999% of microorganisms (This is a 1,000,000 X reduction)

Obviously, “momentarily” is a key fator because the surface will be contaminated again as soon a a contaminant will enter in contact with the it. That’s why some disinfectants have a residual effect that prolongs the action of disinfectant for a certain time.

An Objective Approach to Monitoring Hospital Cleanliness

ATP-tester-lalema

The days when visual room inspection used to be the gold standard for monitoring hospital cleanliness is long gone. Even though this practice is still useful, better and more objective ways have seen the light. One of the most scientific way is surface cultivation. However, surface cultivation is labor intensive and lacks on the spot results. Invisible UV markers and UV light are also a good way to validate if a place was cleaned. However, its application is limited and the data are not telling more then if a surface was cleaned or not at a given time. ATP testing is becoming more and more useful to verify cleanliness beyond visual inspection.

How does ATP monitoring works?

ATP monitoring is a simple and quick way for hospital to measure residual organic matter on a surface, device or piece of equipment. Adenosine triphosphate or ATP is an organic molecule found in every living or once-living organism. Essentially, the person conducting ATP monitoring swabs the surface of concern, and insert that swab into a handheld unit called a luminometer. Results are available within seconds. Good products will come with a free software that will permit to identify problematic areas, monitor trends and store results. It is a very tool to add to an audit system.

Fast, reliable and quality results

It is important to understand that ATP testing is not a microorganism detection method. ATP testing, is a cleaning verification test. It won’t tell you what’s on the surface, but it will tell you that there is something on the surface. A lot of healthcare professionals see the value that ATP monitoring offers. It empowers auditors, infection prevention staff and environmental services specialist to verify if cleaning was done properly in seconds. The speed at which the results are obtained is very appreciated in healthcare settings. If a result is out of specification, then corrective action can be taken immediately. Infection control staff often witness a direct correlation between low ATP levels and lower healthcare associated infection rates. Remember that environmental contamination is directly linked to up to 40% of healthcare associated infections.

Zika Virus, Where Does It Come From?

Everything started back in the 40s. A research team in Uganda, lead by Alexander Haddow, was studying the yellow fever virus near Entebbe. In April 1950, the team isolates a new virus from a monkey used as a test animal in the Ziika forest.

The first human clinical case was described in 1954 in Nigeria. Then, in 1956, an experiment was conducted on a volunteer who got infected with the Zika virus through bites of infected mosquitoes. The subject developed a weak fever with a mild skin rash. The symptoms disappeared within a week. No more doubt, the Zika virus can infect human being via a mosquito bite.

The Zika virus was isolated in numerous species of Aedes mosquitoes in Africa and Malaysia. In 2007, the virus was identified in Micronesia, in what was the first large scale epidemic. Since then, the Zika virus has been considered as an emerging virus.

Aedes aegypti Mosquitoes

During 2013, an outbreak was raging in French Polynesia. The virus rapidly spread  and was confirmed in the five archipelagos of French Polynesia which count roughly 270,000 inhabitants. Between October 2013 and March 2014, the number of infected persons is estimated at 28,000 individuals. 73 cases of Guillain-Barré syndrome were described during this epidemic. The Guillain-Barré syndrome is a rare affection that can cause muscle weakness and even paralysis. Sporadic cases of Zika virus disease were described throughout Oceania.

In Brazil, at the start of 2015, an increasing number of patients presenting symptoms similar to the Dengue virus disease were observed. This increase stroke the attention of Brazilian Public Health authorities. An infectious disease specialist evaluated some patients and laboratory results confirmed that the virus was not the Dengue nor the Chikunguya virus. In March 2015, the Zika virus was confirmed by the Carlos Chagas Institute. It was the first time that Zika virus disease was contracted in the Americas.

The virus strain isolated in Brazil is somewhat close to the Asian strains with similarities to the virus isolated in Oceania a few years ago. Some experts believe that the virus was imported into Brazil during the World Championship of pirogue (va’a) that was held in Brazil in August 2014. Four Oceanian countries where the virus is circulating were present at the Championship. To this day, it was estimated that about 1.5 million cases of Zika virus disease occurred in Brazil, which makes it the biggest Zika virus outbreak ever recorded. It is now spreading to other countries where the Aedes mosquitoes are present. The Zika virus is suspected to be linked to microcephaly touching the fœtus of infected mothers. According to the Brazil Health Minister, 4,783 suspects cases of microcephaly were described so far (February 2016). Active research is  ongoing to find if and how can the Zika virus be related to birth defects.

Zika Virus is there a Risk for Surface Contamination?

zika virus

Zika virus is an arbovirus transmitted by Aedes mosquitoes. It was discovered in 1947 in a monkey in Uganda. Zika virus is mainly present in Central America and South America but also in Africa and Oceania.

Zika virus, what is it?

With the Zika virus, it is reporteded that nearly 3 out of 4 infections do not present any symptoms. When symptoms occur, it looks like the flu: fever, headache, body aches with rashes, beginning 3-12 days after being bitten by mosquitoes. Zika virus can also manifest as conjunctivitis or pain behind the eyes, as well as swelling of the hands or feet. The disease is not directly fatal.

Why are pregnant women particularly at risk?

If a pregnant woman is infected, she can pass the virus to her baby through the placenta or during birth.

It is suspected that pregnant women infected with the virus could give birth to babies with microcephaly. Babies are born with a head circumference below 33 cm and irreversible mental retardation.

However, there is no fully proven causal link between Zika and microcephaly and because some mothers do not believe they had the virus.

What precautions should you take?

There is no vaccine against the Zika virus. It is recommended to protect yourself against bites by wearing long clothing and using insect repellent and mosquito nets.
According to the official website of the Government of Canada (canadaensante.gc.ca)

No local transmission of Zika virus have been reported in Canada. At present, the mosquitoes that transmit Zika virus are not found in Canada because of the climate. So the likelihood of transmission is very low in the country.

Lassa fever could become a topic of much more serious concern

The media focus on the Zika virus is currently brings shadow on the epidemic of Lassa fever now raging in Nigeria and Benin. Lassa fever is a hemorrhagic fever often compared to the Ebola virus.

Low potential for contamination of surfaces

Zika virus is mainly transmitted through mosquito bites. However, hygiene and safety should follow their normal procedures including disinfection of high potential contamination of surfaces and hand washing.

Press release of the MSSS

On 29 January 2016, the national public health director, Dr. Horacio Arruda, also issued a statement to inform the public about Zika. You can read the detail here

How to obtain a more effective disinfection with Certiklör?

How to obtain a more effective disinfection with Certiklör?

What is Certiklör? The name of a new chemical? A new government certification?

None of the above! Simply put, Certiklör technology is the insurance for you, your patients and all Canadians to achieve a better, more efficient and high quality disinfection. Certiklör is a proprietary technology developed by Lalema for you. This technology ensures that you have in the bottle, an effective stabilized hypochlorite, and here to stay!

Stabilized hypochlorite?

Yes, yes! Let me explain. The hypochlorite that is found in bleach for example, flies away usually at a fast rate of more than 1% per month. This means that after 12 months, there will remain only small amounts of the active ingredient: the hypochlorite found in bleach! Imagine how fast this bleach goes away when it’s on the surface to be disinfected in the open air when it does so quickly when, in a closed container!

The difference with our Certiklör stabilized hypochlorite?

The name says it all: stabilized hypochlorite!

Our multidisciplinary team of skilled scientists took 2 years to stabilize the hypochlorite solution. What is the secret? I’m afraid that’s like a little like the Caramilk’s secret! All I can say is that the ingredients that uses this technology have been carefully selected and expertly designed to give hypochlorite increased stability.
And who says stabilized hypochlorite, says better disinfection, less smell and increased cleaning!

How to know if a product uses Certiklör stabilized hypochloritetechnology?

Now, how can you determine which Lalema products use this technology ? Easy! Look at the product label! For now, look at Ali-Flex RTU and Ali-Flex LF.
So if you care about your health, life quality and efficiency at work, think Certiklör stabilized hypochlorite!

How to reduce fatigue and nosocomial infection at the same time

anti-fatigue mat

Working long hours in an upright position rings a bell to you? Back pain, stress and fatigue are your daily meals? There may be a solution for you.

First: Reduce fatigue with an anti-fatigue mat

One of the features found in this type of carpet is the presence of an absorbent foam. Has it been developed by NASA? In fact, we only need to know if it works. If fatigue is reduced and comfort is improved, then risk of injury and error is reduced.

Second: a unique environment

Anti-fatigue mats are found in dry, wet or oily environement. It is however possible to have a dry environment where there is a risk of contamination.

Most ergonomic mats designed for a dry environment have no backing as shown by the following picture:

without backing
When the mat is placed in an environment where there is a risk of contamination, for example in a intensive care unit, a nurse workstation or an examination room, this can be a real problem. Indeed, how can one ensure the disinfection of such a foam pad, an absorbent material, is located under the carpet ?

A suitable carpet to reduce fatigue for the Healthcare Environment

The solution? Get a sealed carpet. This is exactly what was done with the Pure-Clean anti-fatigue mat.

with backing

Pure Clean carpets (also known previously under the name Pure Ergo-by Lalema) is an ergonomic mat designed specifically for critical areas in terms of infection control.

  • Non-porous carpet completely sealed sides
  • Resistant surface cuts and punctures
  • Very easy to clean and disinfect
  • Excellent anti-fatigue properties

Dilution is the solution

dilution

The dilution of chemical products in housekeeping is certainly one of the aspects where the lack of knowledge is most evident.

Dilution is often misunderstood

Effectively, there are unfortunately too many housekeepers that have the habit of adding a too large quantity of chemicals to their washing solution. Therefore, if they would come to a stop for an instant, in order to realize up to which point this may be harmful to their work, this bad habit would be lost very quickly.

We must indeed remember that cleaning chemical products are conceived to reach their maximum potential with a very precise volume of water.

Consequently, we must use a dilution measuring system that should be standardized for the whole working team.

Effects of under-dilution

With respect to Health and Safety, under dilution can cause:

  • Dermatitis problems
  • Respiratory tract problems
  • Toxic fumes may cause cancer, difficult to prove and difficult to be recognized by the CSST.

With respect to work efficiency and surfaces, under dilution can:

  • Damage surfaces, since an under-diluted alkaline product will make a dull effect, by opening the pores of the floor coverings and thus allowing the deposit of alkalis. Acids, on the contrary, close the pores of the floor coverings and also burn the surface.
  • Leave a film on the surface that will give a continuous streaky appearance and this film being greasy will facilitate the adherence of dirt.
  • Cause enormous rinse problems because it will create foam in the solution container, which anyway has no cleaning effect.
  • Disturb disinfection efficiency.
  • Result in a loss of efficiency, since a well-diluted product reduces the physical demand to perform a task and favors the mechanical action.

Effects of over-dilution

Over dilution can cause:

  • Result in no disinfection.
  • Result in loss of efficiency since an over-diluted product will increase the physical workload at the expense of the mechanical action.

The right dilution is always the best solution

The use of a dilution system does not have to be complicated or costly. Portable system such as Optimixx Portable Dilution System can be used as so.
