Disinfection

Better understanding disinfection

Jimmy Tremblay

Introduction

Disinfection is the process by which microorganisms such as bacteria are eliminated or reduced. The objective of disinfection is to prevent the spread of infectious diseases by reducing the number of microorganisms present. Disinfection can be achieved in various ways, including the use of disinfectant chemicals such as alcohol-based disinfectants, quaternary ammonium compounds, sodium hypochlorite (bleach), or hydrogen peroxide.

Effective Planning and Disinfection Management

This would be the planning. We need to develop a detailed plan for management and disinfection. It is important to identify high-risk areas, determine the necessary equipment, outline the procedures to be followed, and define the responsibilities of the individuals involved in the disinfection process.

  • This is training. It involves ensuring that the personnel responsible for management and disinfection are trained in good hygiene and disinfection practices. They should be familiar with the procedures, the cleaning/disinfection products to be used, and the safety precautions to be taken.
  • This is personal hygiene. We should encourage and maintain good personal hygiene practices among the staff. This includes habits such as regular handwashing with soap, the use of hand sanitizers, and wearing appropriate protective clothing.
  • This is regular cleaning. It entails establishing a regular cleaning schedule for all surfaces and high-risk areas.
  • This is proper disinfection. It involves using appropriate disinfectants to kill germs and reduce the risk of infection.
  • This is ventilation. We should ensure good ventilation in indoor spaces to facilitate the circulation of fresh air.
  • This is waste management. We need to implement an appropriate system for waste management, ensuring the safe and hygienic disposal of potentially contaminated materials.
  • This is monitoring and evaluation. It entails establishing regular monitoring and evaluation procedures to assess the effectiveness of the management and disinfection measures. Adjustments should be made if necessary.
  • This is raising awareness among staff and relevant individuals about hygiene practices.
  • This is compliance with regulations. We must ensure that regulations regarding hygiene are adhered to and that standards are upheld. Therefore, it is important to stay informed about updates and recommendations from health authorities.
The uses/benefits of disinfectant

Eliminates germs and bacteria, ensuring a clean and hygienic environment for everyone.

Surface Disinfection: This category involves the disinfection of surfaces such as countertops, doorknobs, switches, phones, keyboards, faucets, etc. There are specifically formulated disinfectant products to eliminate germs and bacteria on surfaces. These products can be disinfecting wipes, sprays, or disinfectant solutions to be used with a clean cloth.

Hand Disinfection: This refers to the disinfection of hands to eliminate germs and bacteria that may be present. The use of alcohol-based hand sanitizers is common in this category. Hand sanitizers are usually available as gels or liquid solutions. It is recommended to rub the hands with the sanitizer for at least 20 seconds until it dries.

Medical Instrument Disinfection: This category primarily concerns healthcare facilities and medical professionals. It involves the disinfection of medical instruments such as scalpels, syringes, injection devices, probes, etc. In this case, more complex disinfection procedures may be required, such as the use of autoclaves, dry heat sterilizers, or specific chemical agents.

To conclude, disinfection is essential to ensure good hygiene in the workplace, and it requires precise steps to be properly carried out.

When we talk about disinfection, we talk about the prevention and control of infection in the environment. Therefore, equipment used for respiratory therapy is considered semi-critical. The equipment must then be cleaned and disinfected properly between patients. The WHO gives us the proper maintenance of respiratory equipment in procedures to follow. The procedures are checklists in steps of a cycle. Let’s explore all the summarized steps up to the cycle finish. And yes, the cleaning step is before the disinfection step!

Checklists for care, cleaning, disinfection and sterilization of respiratory devices

1. Perform hand hygiene

The title and image say it all

2. Don appropriate personal protective equipment

The personal protective equipment to be worn during the disinfectant preparation includes surgical mask/respirator, googles/face shield, long-sleeved fluid resistant gown/gown plus apron, rubber gloves and boots or closed work shoes.

3. Wash with detergent and rinse with clean water

The external device surfaces must be wiped with a damp cloth or disposable wipe that is soaked in detergent and clean water. Then, remaining detergent residue must be wiped off with a dry lint-free cloth. A mechanical action (scrubbing/brushing) should be used to remove visible dirt deposits and calcifications.

4. Disinfect

4a. Physical disinfection – Heat for heat resistant equipement (steam/hot-water)

A high-level of physical disinfection can be achieved with steam (e.g. autoclaving at lower temperature) or hot-water at least 121°C. This is an inexpensive and effective method for sterilization or high-level disinfection.

4b. Chemical disinfection for plastic plus other parts that can be damaged by heat

b) If the disinfection needs to be with chemicals solutions, it should be performed in a well-ventilated area and away from patients. Use a disposable wipe or a fresh cloth that is soaked in a compatible disinfectant. Hydrogen peroxide 0.5% or ethanol 70-90%. Wipe from top to bottom and avoid contact with electrical connectors.

5. Dry equipment / Rinse equipment

a) Physical equipment often has a drying feature within the machine (e.g. washer, pasteurizer or autoclave). Following pasteurization, the wet equipment is typically dried in a hot-air drying cabinet or air-dried. Make sure to carefully inspect and ensure that no water is left in the equipment.

b) If a chemical solution was used for disinfection, rinse the equipment with sterile or clean water (i.e. water boiled for 5 mins and cooled down). It is preferred to use sterile water for rinsing off residual liquid chemical disinfectant from the respiratory device.

6. Store equipment in closed packages

Last step. Title says it all.

What’s best? To clean or to disinfect?

Gaétan Lanthier

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 a real definition.

Deteriorated surfaces definition

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 definition

Safe surfaces definition

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 definition

Disinfected surfaces definition

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.

GPT3: An AI generated blog post about disinfection

Gaétan Lanthier
GPT3 AI generated image : “A janitor cart in a hospital patient room”

GPT3 Input

gpt3> write a 250 words article about how hard surface disinfectant will become more essential in the future.

GPT3 Output

As the world becomes more populated and the spread of disease becomes more prevalent, the need for hard surface disinfectants will become more essential. Hard surface disinfectants are a key part of preventing the spread of disease, and as the world becomes more connected, the need for these products will only increase.


There are a number of factors that contribute to the spread of disease, and hard surface disinfectants are an important part of preventing the spread of infection. The main factor that contributes to the spread of disease is contact with contaminated surfaces. Hard surface disinfectants kill the bacteria and viruses that are present on surfaces, preventing the spread of infection.


Another factor that contributes to the spread of disease is the presence of food and water sources that are contaminated with bacteria and viruses. Hard surface disinfectants can also be used to clean these contaminated surfaces, preventing the spread of disease.


In addition to these two factors, there are a number of other factors that contribute to the spread of disease. These include the presence of sick people in close proximity to others, the sharing of contaminated items, and the exposure to contaminated air. Hard surface disinfectants can also be used to clean these contaminated surfaces, preventing the spread of disease.


The need for hard surface disinfectants will only increase as the world becomes more populated and the spread of disease becomes more prevalent. Hard surface disinfectants are a key part of preventing the spread of disease, and as the world becomes more connected, the need for these products will only increase.

Disposable Microfiber, The First Step In The Disinfection Process

Rémi Siv
Disposable microfiber cloth system

In the past, we have often lauded the advantage of microfiber for cleaning. This is repeated today, but with the use of a disposable microfiber as the first step in the disinfection process. Of course, we are talking about cleaning first, then disinfecting. However, the products highlighted in this article are compatible with common disinfectants. These products are Rubbermaid‘s Hygen single-use microfiber swabs and wipes.

WHAT IS A MICROFIBER AGAIN?

Microfiber is a synthetic textile fiber (polyester, polyamide or a mixture) that is very fine and light with a denomination which is less than one decitex. A microfiber (filament) is characterised by its small diameter, the nature of its fiber and its structure. Therefore, not all microfibers are the same or of the same quality. This revolutionary material has quickly become a must in the hygiene, health and automotive sectors. To know more about it, read this article, Spotlight on microfiber!

THE HYGEN LINE FROM RUBBERMAID

The Hygen line was designed specifically for the healthcare industry. It is an excellent option for any facility looking to improve its cleaning efficiency, especially during the COVID-19 period. The HYGEN disposable microfiber pad and wipe contribute to the area cleaning as the first step in the disinfection process.

Microfiber pads and wipes

Disposable Microfiber Pads HYGEN
  • They eliminate 99.7% or more of the viruses and bacteria tested to help improve cleaning efficiency. And this was tested with water only
  • Help reduce cross-contamination with disposable pads/wipes that encourage cleaning with new pads/wipes for each area or task
Disposable Microfiber Wipes HYGEN
  • They are compatible with common disinfectants, including Quat (does not bind), bleach and hydrogen peroxide
  • Built-in scrub strips are made of polyester to help effectively remove dirt

DEMONSTRATION OF THE DISPOSABLE MICROFIBER

Here’s a video from Rubbermaid Commercial Products. They demonstrated the benefit of their Hygen disposable microfiber wipe compared to a paper towel and a disinfectant wipe. They use a fluorescent marker to demonstrate and verify cleaning practices.

Thus, using this disposable microfiber with a disinfectant provides an added layer of assurance. They will clean and disinfect well your floors and surfaces by combining the microbe removal power of the microfiber with the disinfectant’s killing power.

Electrostatic disinfection

Rémi Siv
Siozen electrostatic sprayer

Since the beginning of the pandemic, demands for electrostatic sprayers have exploded as an efficient way to disinfect key touch points and ensure environmental safety. While effective on a wide range of surfaces, it is important for cleaning teams to understand how it works, the cost considerations and the best facilities for using it. Therfore, this is a free translation of Cleanlink‘s article, What to know about electrostatic spraying.

What’s electrostatic disinfection

Electrostatic spraying or disinfection is the process of spraying an electrostatically charged mist onto surfaces and objects.

The electrostatic sprayer is electrically charged, allowing the specialized solution and disinfectants to envelop and evenly coat all types of surfaces. Designed to kill germs, bacteria and various types of viruses. It is a safe, fast, effective and non-contact application to limit the risk of cross-contamination.

How does it work?

Siozen - how it works

Electrostatic sprayers use positively charged atomized particles to electromagnetically adhere disinfectant chemicals to negative target surfaces.

They use an electrode inside the sprayer to atomize the cleaning solution. The particles emerge from the nozzle as a spray that clings to any contact points it can find.

For example, no matter what angle it is used for surfaces disinfection, the droplets created by the electrostatic sprayer cause the disinfectant to cling to areas such as chairs, under tables or desks.

Although it is easy to apply, well-trained personnel is essential to ensure that the application process is optimal and safe for the staff.

What are the costs?

The cost generally depends on the type of facility as well as the size of the area to be treated.

In the long-term, electrostatic disinfection protects businesses from costly financial issues associated with contagious healthcare infections. It also reduces the costs associated with providing effective disinfectant solutions.

Is it effective against COVID-19

This depends since the electrostatic sprayer does not, in itself, kill COVID-19 or the coronavirus. The disinfectant to be used in conjunction with this technology must be on the list of disinfectants with evidence for use against COVID-19 by Health Canada. Lalema‘s Myosan TB is one of them.

What types of properties are best suited for electrostatic disinfection?

This process is perfect for a variety of property types, including office buildings, healthcare facilities, shopping centers, industrial parks, condominiums, educational facilities, and government and hospitality projects. It also reaches a vast number of areas that highly covered by bacteria, otherwise difficult to access with standard cleaning methods by applying a uniform, solid coating to all surfaces.

Electrostatic disinfection is widely used in healthcare facilities as a safe and effective process in viral infection control programs, providing non-contact cleaning, thereby limiting the spread of bacteria.

Disinfection in 3D

Rémi Siv

Reading time: 2 mins

Building managers are learning a lot about hidden pathogens with new 3D imaging technologies now available in North America. They are learning especially a lot in healthcare, education sectors and foodservice industry.

Essentially, these systems create a map which indicates the locations and amounts of pathogens on a surface. According to a press release from the infection prevention technology company, Optisolve, what has evolved in this learning is the “3Ds” of cleaning in order to help prevent the spread of infections.

IMAGES IN 3D

The 3D images refer to the three key challenges that building managers should manage to help ensure that building users stay healthy, says Optisolve CEO Brad Evans.

According to Evans, 3Ds refer to the following:

DETECT

The first step in keeping users healthy is to locate health-threatening pathogens in the building.

DISINFECT

Once located, these surfaces must first be cleaned and then disinfected.

“As with ATP monitors, imaging technologies cannot determine what pathogens are present,” says Evans. “As a result, ‘broad range’ or ‘broad spectrum’ disinfectants that kill a variety of pathogens should always be used.”

DISCUSS

For example, if pathogens are located on one window ledge, this information must be discussed and shared with administrators and all cleaning professionals in the facility.

“Unfortunately, when imaging technologies point out a potentially contaminated surface, administrators and cleaning professionals often believe the problem is confined to that specific area” says Evans. “In many cases, however, if one specific area is contaminated, we find the same problem in similar areas throughout the facility.”

Cleaning in Hospitals (part 4)

Gaétan Lanthier
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!

This is all for this series of posts on Cleaning in Hospitals! Don’t forget that we’re always here to help, don’t hesitate to book an appointment by calling 514.645.2753 or subscribe to one of our training seminars. I really hope that you liked this serie of posts!

Cleaning in Hospitals (part 3)

Gaétan Lanthier
cleaning-hospital-staff

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!

The next post is going to talk more in detail about one aspect of their profession: work organization.

Cleaning in Hospitals (part 2)

Gaétan Lanthier
cleaning-hospitals

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 next post of this series is going to talk about another key factor: the hygiene and cleanliness staff.

Cleaning in Hospitals (part 1)

Gaétan Lanthier
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.

Have you already performed an infective risk analysis? The next post is going to explain how cleaning allows reducing risks of infection among patients.

A Brief History of Bleach 2021

Gaétan Lanthier

Bleach has been studied for the first time by a French chemist named Claude Louis Berthollet in 1775. His factory was based in Paris in the district of… Javel! That is why the French are calling it: Eau de Javel (Javel Water).

Javel Underground, Paris, France

At first, bleach was used for laundry and as a fade. From 1820, a pharmacist named Antoine Germain Labarraque studied more deeply its disinfecting properties . In the XIX Century, it was commonly used as a disinfectant and water treatment. The NASA used bleach during the Apollo program to disinfect the Apollo XI rocket after its return, in order to avoid contaminating Earth with potential dangerous viruses!

What is Bleach?

Bleach is composed of sodium hypochlorite (NaClO). For chemistry fans, its chemical formula is as follows:

Cl2 + 2 NaOH → NaCl + NaClO + H2O.

For those who don’t like chemistry, well… the formula is the same!

What’s new with Bleach?

Nowadays, bleach is still used as a disinfectant. Stabilized formulas enable to combine the disinfecting ability of chlorine together with the cleaning ability of surfactants.

Clean first, then disinfect

Rémi Siv
Cleaning with a microfiber cloth

Cleaning and disinfection have long been routine in any facility. Of course, the COVID-19 pandemic has further highlighted these operations since SARS-CoV-2 can persist on various surface materials for hours or days. Facilities have sought to improve these cleaning and disinfection practices. Therefore, it is imperative that this process be orderly. Therefore, this article addresses the importance of cleaning before disinfecting. Cleaning and disinfection should be a 2-step process to reduce the risk of transmission of environmental infections.

Clean first! Why?

Primum nitidare – “D’abord nettoyer (Clean First)”. It is a book that my coworker, Gaétan Lanthier, wrote in 2019. It is to say that this is not a new subject!

Centers for Disease Control and Prevention (CDC) cites: “cleaning is “the necessary first step of any sterilization or disinfection process” or, more
simply, you must clean first before you can disinfect.”

The CDC adds: “Cleaning is the necessary first step of any sterilization or disinfection process. Cleaning is a form of decontamination that renders
the environmental surface safe to handle or use by removing organic matters, salts, and visible soils, all of which interfere with microbial inactivation.”

It’s in the mechanical action (friction)

As the CDC mentions it: “The physical action of scrubbing with detergents and surfactants and rinsing with water removes large numbers of
microorganisms from surfaces.”

Studies have shown that friction or mechanical action is at the heart of cleaning. This facilitates the effective removal of dirt, debris, microbes and soiling, making a surface ready for disinfection if necessary.

It’s a matter of interference

The CDC defines cleaning as the “necessary first step” in any disinfection process for “at least two” important reasons: it removes any barrier between the disinfectant and the target pathogen, and it removes materials that could potentially inactivate the disinfectant.

In order to effectively kill pathogens, disinfectant chemicals must have direct contact with the pathogen; however, soils, dirt, and debris can coat or
protect microorganisms, essentially serving as a protective barrier between the chemical and the target.

The build-up to biofiolms

Another important reason to clean first before disinfecting has less to do with the immediate action of a disinfectant on a surface. Rather, it is in prevention of a future problem, namely the buildup to biofilms.

Biofilms are populations of microorganisms attached to a solid surface and protected by a “viscous layer”. This layer is an extracellular matrix of polysaccharides and non-cellular materials.

Biofilms can virtually form on any hard surface, from the countertop to the water pipe. They are involved in a range of infectious diseases.

What about touch-free technology?

Comac ULVC Electrostatic Sprayer for Disinfection

Although research has shown that many of these systems, from ultraviolet light (UV-C) to hydrogen peroxide vapor (HPV) to electrostatic sprayers, can reduce microbial contamination, experts caution that they should be used as a complement to standard manual cleaning and disinfection rather than as a replacement.

Organic matters, dirt and grimes are a limiting factor for UV-C technology.
A light or heavy organic load has a significant negative impact on the destructive efficiency of the devices.

In short, clean first with mechanical action (friction) to remove dirt, debris and microbes. The disinfection step is to be done when the interferences are removed by cleaning in order to kill microbes. This reduces the risk of transmission of environmental infections by keeping surfaces clean.

Disinfection – The Power of Steam

Rémi Siv
Credit – Andrew Knechel Unsplash

Disinfection using disinfectant cleaners with active ingredients including alcohol and quaternary ammonium has often been discussed. Another disinfection solution is to disinfect with steam and pressure. Cleaning with the power of steam is a proven method of disinfection. Dry saturated steam at high temperatures kills viruses, bacteria, germs and bedbugs! It is an environmentally friendly and practical way to clean all kinds of surfaces.

THE POWER OF STEAM

The power of steam is to dissolve and emulsify grease, mold, dirt by vaporizing and killing viruses, bacteria and germs.

WHAT ABOUT SARS-CoV-2?

Despite that the power of steam kills viruses, bacteria and germs, opinions vary and there may be a lack of evidence that it can kill SARS-CoV-2 virus. The list of approved disinfectants put out by The Environmental Protection Agency only includes chemicals.

Patty Olinger, the executive director of the Global Biorisk Advisory Council, a division of ISSA (a cleaning industry trade association), said that, based on current evidence, while steam can kill the virus, it needs a lengthier application time than some users may realize.

On the other hand, Heidi Wilcox, a microbiologist and commercial cleaning consultant, says that: “At this point during the pandemic I would not use steam at all.” She cites a lack of strong evidence.

Then again, industry representatives such as Wayne Delfino from Advanced Vapor Technologies of Everett, Washington, insist that dry steam vapor works. The company’s non-chemical, “Thermo Accelerated Nano Crystal Sanitation” technology, he wrote in an email, “has been tested and proven effective on harder-to-kill viruses and on a similar human coronavirus in seven seconds or less.”

SURFACES TO CLEAN

Steam cleaners can clean and disinfect all kinds of surfaces. With the right tools, they can concentrate the jets to properly clean specific surfaces and hard-to-reach areas. Here are some examples:

  • Clothing
  • Mirrors
  • Seals (e.g. ceramic)
  • Mattresses and bedding
  • Stainless steel
  • Floors
  • Grids and hoods
  • ECOLOGICAL
  • Steam machines are said to be environmentally friendly because they require no chemicals. Only water is needed to steam disinfect and clean thoroughly.

NEED STEAMER MACHINES?

Power Steamer Machine JS 1600C

Power Steamer Machine JS 1600C

The power of steam from JS1600C attacks grease, grime, hard water deposits and mold. It leaves surfaces clean and sanitized without the use of chemicals. Operator safety is assured by the 12V waterproof switches and controls, a pressure switch, a high-limit thermal shutoff and an LED display informing the operator when the water level is low. The Energy saving safety system also automatically shuts off the machine if it’s idle for 60 minutes.

  • The tank can be filled while the unit is running, allowing for continuous use
  • Excellent on grouted floors, showers, kitchens and any area where detail cleaning is a challenge
  • Very effective in all food preparation and processing areas, including stainless steel range hoods in kitchens
  • Ideal for hotel rooms – spot draperies, bedspreads and carpets, and even kill bed bugs and their eggs on mattresses
  • Clean floors with the optional “steam mop” and 33′ hose
  • The continuous flow system provides the necessary steam to remove dirt and built-up soil while leaving your floors and surfaces virtually dry

Ecological Vapor with Vacuum A2006

Commercial Ecological Vapor with Vacuum A2006

The Vapore A2006 acts as two machines in one unit. The vapor not only dissolves dirt and grime, but is scientifically certified to disinfect any surface, thoroughly eliminating bacteria and viruses in an ecological way without use of chemicals.

  • With the water filtration system of the vacuum, Vapore A2006 collects dirt and traps it in the water without the risk of spreading dust
  • Vapore A2006 also has a HEPA filtration system to ensure the cleanliness of the air is not compromised
  • Equipped with a cold water reservoir, the Vapore A2006 has a continuous fill feature which allows you to refill the vapor system with water at any time, without stopping
  • The machine comes with a variety of floor accessory and tools

There’s no proof that the power of steam can kill SARS-CoV-2, but the virus is known to be sensitive to the exposure of high-temperature. Could it be a question of exposure length or a question of chemicals? However, the power of steam can be useful for general disinfection.

The COVID-19 has led us to adopt new protocols to ensure patient and staff safety in healthcare facilities. Having said that, it is crucial to equip yourself with the right surface cleaning and disinfection products in healthcare facilities! What are the right products? How should you clean? Let’s explore them with the help from Rubbermaid Commercial Products, a world leader in the commercial cleaning industry! Of course, in these strange days, depending on the availability of some products, Lalema has suggestions as well ;)!

SURFACE CLEANING PRODUCTS

First of all, here are some products suggested by RCP for surface cleaning. Overall, most of them are available. Otherwise, we have replacements.

BEST PRACTICES

Second, as expectations for cleanliness and hygiene rise, facilities must ensure that they have an established surface cleaning and disinfection process. This includes regular cleaning of high-traffic areas. Below are the best surface cleaning practices used in hospitals around the world today.

CLEANING TIPS

  1. Clean systematically, clockwise or counterclockwise – No surface is forgotten, this process saves time and is more ergonomic
  2. Go from clean to dirty – This reduces the likelihood of the spread of infections and contaminants
  3. Clean from the top to the bottom – Any dust or debris dislodged from the upper surface will naturally fall to the lower surfaces
  4. Wipe in one direction (unidirectional wiping) – Unidirectional wiping ensures that the solution is applied over the entire surface, while circular wiping re-contaminates areas
  5. Color Coding – Use single color wiping cloth for each zone. For example:
  • Red for high risk areas
  • Blue for mirrors
  • Yellow for baths and showers

8-SURFACE FOLDING METHODOLOGY

Finally, the 8-surface folding methodology! This is the 8-sided folding for microfiber cloths. It optimizes the use of the cloth while reducing the risk of cross-contamination during the cleaning process. Here are the steps:

8-SURFACE FOLDING METHODOLOGY
8-SURFACE FOLDING METHODOLOGY

8-surface folding methodology by Rubbermaid Commercial Products

  1. Start by opening a clean microfiber cloth
  2. Fold the microfiber cloth in half
  3. Fold the microfiber cloth into four pieces
  4. Clean surfaces with both sides of the cloth exposed
  5. Open the microfiber cloth once to change the sides
  6. Fold over to expose both clean cleaning surfaces
  7. Fully open the microfiber cloth when all four sides have been used
  8. Repeat steps 2 to 7 to use all eight sides

In short, these tips are only general since we could have gone deeper into the details or in further checklists. However, the importance is to set up a methodology for surface cleaning and disinfection and to be equipped with the right products. Don’t forget to wear personal safety equipment! Let’s save the subject of floor cleaning for another day!

Lalema would like to thank and salute all the staff in the healthcare facilities for their services!

Places in your community that are high-risk for the spread of infection

Sara Lafond

I recently read an article on Infection Control Today, which was titled “Examining Ball Pits as a Playground for Pathogenic Organisms.” This article was surprising because, although it seems so obvious now, I would never have even thought about ball pits as a potential source of infection. And yet, ball pits are frequently filled with children, who are known to be more at risk for catching and transmitting infection, and are infrequently disinfected afterwards.

This led me to wonder which other places part of our every day lives are often overlooked as being a source of infection. After doing some more research on the subject, I’ve decided to share with you what I found out.

Source: DoD Live

Playgrounds

Similar to ball pits, it is no wonder that playgrounds are one of the germiest places in the community. Every day, many children go to the playground and make use of the equipment there. And as we all know, children are at high risk for catching and spreading infection. According to Web MD, the sandbox is one of the worst places in terms of contamination, since the sand absorbs bodily fluids like saliva or urine and there is no way to wipe it down after its been used.

Public Restrooms

It should come as no surprise that pubic restrooms appear on the list of high-risk places for germs. However, I’m not sure if people realize to what extent they are contaminated. You wouldn’t touch a toilet seat in a public restroom, but it turns out that faucets and door handles are also extremely contaminated. According to Web MD, even if you’ve washed your hands, you’re still at risk for contamination when you touch the door handle to leave the bathroom. This is because only 31% of men and 65% women actually wash their hands, meaning that the rest contaminate the door handles when they go to open it (Web MD, 2018).

Grocery Stores

You may have already heard that there are a lot of bacteria in grocery stores. The majority are found on shopping carts, where, for example, raw meat packages carrying salmonella are placed or babies are seated with dirty diapers. Most grocery stores have disinfectant wipes near the entrance with the carts, so it is advised that you use them.

Public Transportation

Metros and buses are filled with germs! And it’s not surprising to see why. Thousands of people use public transportation each day, making seats, poles and handles high-touch areas. This makes public transport one of the biggest sources of harmful bacteria.

Gyms

Similarly to all the other sources, gyms are filled with bacteria due to the high number of people who use equipment every day. According to Web MD, it was found that some free weights carried the same types of bacterias found in public restrooms (ick!). It is advised that you use the wipes provided at the gym both before and after using the equipment in order to protect yourself and prevent the spread of bacteria.

What can you do to protect yourself?

You may be wondering how on earth you’re supposed to protect yourself, when you’re surrounded by bacteria! While you can never avoid every germ, there are many ways to protect yourself and avoid getting sick. Web MD (2018) makes the following recommendations:

  1. Wash your hands for 20 seconds with soap and water. And do it often.
  2. If you don’t have access to soap and water, use alcohol-based sanitizer.
  3. Don’t touch your eyes, nose or mouth until you wash your hands.
  4. Use a spare paper towel to grab the public restroom door handle as you leave.

Are technological devices a source of hospital-acquired infections?

Sara Lafond
Source: Air Force Medical Service

You’ve already seen on this blog just how dirty cellphones can get, but did you know that cellphones and other electronics such as tablets and laptops can also cause contamination in a healthcare setting, potentially making them a source of HAIs? Hospital staff use technology throughout their workday, whether it be to enter patient information in a computer or for personal use on their breaks. If they don’t wash their hands before and after using the device, it can become contaminated causing those workers to spread the bacteria all throughout the hospital.

According to Kelly M. Pyrek (2019),

“A casual online poll of ICT readers shows that 83 percent of survey respondents use their personal mobile technology devices within the hospital, and just 68 percent said they clean/decontaminate these devices regularly. Fifty-seven percent of respondents indicated they use a hospital-issued mobile technology device in the course of their workday; 56 percent report cleaning the device themselves, while 7 percent let someone else clean the device.”

Kelly M. Pyrek, Infection Control Today, 2019

Many hospitals are now realizing that technological devices are a potential source of the spread of infection within a healthcare setting and some of them are beginning to implement protocols regarding the use and disinfection of electronics.

That being said, the cleaning and monitoring of technological devices can be complicated. As James Davis, MSN, RN, explains to Infection Control Today (2019), tech companies such as Apple only tell people to wipe down their devices with a damp cloth. However, that recommendation does not take into consideration the use of devices in a healthcare setting, where bacteria and infection are everywhere.

Some recommendations that Davis and Shivek, Phd, senior product engineer, give include:

  • Always washing your hands before and after using your device
  • Placing a layer between the device and the environment is key
    • Phone covers are becoming increasingly popular, however must be replaced frequently
    • Placing the mobile device in a ziploc bag is another option, especially if it’s being brought into an isolation room
  • No matter what, always wipe down the device before and after using it. Even if it was in ziploc bag or had a cover over it, wiping your device is key to ensuring that harmful bacteria are eliminated.

The cleaning and monitoring of technological devices is a daunting task for healthcare facilities, especially if it is an employee’s personal device. Davis (2019) stresses that because of this, employees should be personally responsible for the cleaning and disinfecting of their mobile devices. Although a complicated task, the recommendations provided by Infection Control Today allow us to understand how to better prevent the contamination of our mobile technology, which may in turn help prevent the spread of infection.

COVID-19 and the preventive measures.

Rémi Siv

2019-nCoV is making the headlines these days. What is the 2019-nCoV and what are the preventive measures? Up to now, we don’t fully understand the pathogenic potential and transmission dynamics of this new 2019 coronavirus.

Young woman with respiratory mask

What is it?

In a nutshell, it is part of the coronavirus family. It presents “80% of similarities” with the SARS (Severe acute respiratory syndrome) which killed hundreds of people in 2003. This virus does not spread as well as influenza and doesn’t evolve very quickly. The symptoms are the same as most flu cases: fever, cough, muscle aches, shortness of breath and difficulty breathing.

Last December, the coronavirus appeared in Wuhan, a city in central China. The cities of Wuhan and Huanggang have been quarantined. So far, it has killed 490 people in China and thousands of people have been infected. The virus has also been detected in 23 other countries. In order to limit its spread, measures are being taken in several countries. The WHO (World Health Organization) has declared this virus as an international emergency.

Yellow Crane Tower in Wuhan

What are the preventive measures?

Brief, here are some preventive measures for 2019-nCoV. As suggested by the WHO, the following are strategies for health care-associated infection prevention and control when a case of nCoV is suspected:

  1. Early detection and source control
    – Encouraging health care workers and managers to have a high level of clinical suspicion
  2. Application of standard precautions for all patients
    – Ensure that respiratory hygiene measures are taken by providing a medical mask in case of suspected nCoV infection for those who can tolerate it
    – Cover your nose and mouth by coughing or sneezing into a tissue or bent elbow
    – Wash hands after contact with respiratory secretions
    – Wear personal protective equipment
    – Follow environmental cleaning and disinfection procedures consistently and correctly
  3. The implementation of empirical additional precautions
    – Wear a particulate respirator at least as protective as a NIOSH N95, EU FFP2 certified respirator or equivalent
    – Wear eye protection (goggles or face shield)
    – Use clean, non-sterile long-sleeved coveralls
    – Wear gloves and avoid contact with eyes, nose or mouth with potentially contaminated hands
    – Use disposable equipment or dedicated equipment to be disinfected after each use
  4. Administrative controls
    – Ensure sustainable infection prevention and control infrastructure and activities are in place
    – Provide training and education to health care workers and patients
  5. Environmental and technical controls
    – Ensure adequate ventilation and proper cleaning of the environment

So, do not hesitate to contact us for your needs and questions about our products or hygiene training.

Hospital Staff Cuts and its impact on hospital cleaning

Sara Lafond
Source: Pixabay

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.

To learn more about the consequences of hospital staff cuts, refer to this CBC Marketplace video:

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

Sara Lafond

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.

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

Sara Lafond

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

Sara Lafond

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

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…

Sara Lafond

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 ?

Sébastien Gendron
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?

Sara Lafond

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 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).
