UV disinfection how does it works?

October 29, 2014November 17, 2017Gaétan Lanthier

Since 1877, scientists know the microorganisms can be eliminated by UV rays. Nearly 50 years later, however, they discovered the specific type of frequency that was the most damaging.

In the 1950s, researchers knew that UV rays penetrate cells and damage the nucleic acids or deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). This led to the commercial development of multiple UV disinfection devices, primarily with mercury vapor, which produces UV having the most effective frequency for the destruction of microorganisms. Today, UV disinfection devices use xenon UV rays.

UV disinfection is used in many hospitals

UV disinfection devices are used in hospitals such the ones in Vancouver and Hamilton. It is the natural evolution of the UV disinfection, to which are added the cleaning and disinfecting surface and a good dose of prevention.

Combined with touchless systems for bathrooms and public spaces, hospitals are able to reduce the number of surfaces to be disinfected to prevent nosocomial infections.

In any case, these robots do not replace the housekeeping staff but add a small sector futuristic air … don’t you see a family resemblance with this R2-D2 designed by Agent-Spiff?

Ebola, how does it spread?

October 22, 2014November 17, 2017Gaétan Lanthier

The Ebola Virus

Ebola is a virus. There is currently no vaccine or treatment. It causes severe disease, causing serious symptoms including vomiting and bleeding. The mortality rate can reach 90%. Primary infection comes from a contact with an infected animal and it can spread quickly.

How can you get infected by Ebola?

By coming into contact with following bodily fluids such as blood, urine, feces and vomit. Of by one of the following means: by contact with a dead victim, by ingestion of infected animal meat or by having sexual intercourse with an infected person.

What are the symptoms of Ebola?

The symptoms of Ebola are fever, headache, nausea and fatigue. It may also include bleeding from nose, mouth or eyes, coughing, diarrhea or vomiting with the possible presence of blood.

How to prevent ebola transmission

The risk of transmission of the Ebola virus in Canada is very low. However, certain precautions must be taken. The Public Health Agency of Canada also recommends that travelers avoid all nonessential travel to Guinea, Liberia and Sierra Leone.

There is a risk only if you have been in contact with sick people. In such case, if you experience symptoms, call 8-1-1 (Quebec) and inform them of your discomfort. You will be directed to the healthcare center care that can help you.

What to do to prevent the spread of Ebola virus

The Ministère de la Santé et des Services sociaux in collaboration with the Institut nationale de santé publique du Québec has issued recommendations in case of an outbreak. It is important that each healthcare center that can receive a potentially infectious patient put in place appropriate precautionary measures. Thus, it is important to have the required equipment for this type of care.

Robots are soldiers in a war againt HAI’s

Two Canadian hospitals have recently acquired a machine enabling surface disinfection in health institutions.

The Juravinksi hospital in Hamilton has started a year trial of a robot that costs 95 000 $ that burns the bacteria with UV rays: the Xenex Robot System. The general hospital of Vancouver has also started a trial of a UV robot that is 1.65 meters tall, called the Tru-D Smart UVC, working with UV rays as well. The effectiveness of these machines relies on the properties of the UV rays, or rather on the xenon UV rays, to sterilize and kill microscopic contaminants.

Ebola outbreak

Recently, with the Ebola Outbreak, the Texas Health Presbyterian Hospital in Dallas, where 42-year-old Thomas Eric Duncan, the first person to be diagnosed with Ebola in the US, was being treated, also uses such device. But was it enough? See this other blog post from my collegue: The Dallas case rises a question: Should protocols for infection control be revised?

What about your hospital?

The goal of these robots is not to replace the cleaning staff, nor the products employed for critical disinfections, but rather to complete their work, and to avoid that a single microscopic bacteria could take the life of a person whose immune system is weak.

Is your plan ready? Is your staff trained well enough? Do you have a stabilized chlorinated cleaner disinfectant in stock?

Do not miss our next post, which is going to explain how UV disinfection works!

The Dallas case rises a question: Should protocols for infection control be revised?

October 14, 2014November 17, 2017Rémi Charlebois

A nurse from the Texas Health Presbyterian Hospital, where a patient was treated for Ebola, contracted the disease. This is the first case of Ebola transmission in North America. Although the authorities are reassuring, the question arises in hospitals: Are protocols in place really effective?

The nurse in question, Ms. Nina Pham wore protective equipment as directed by the hospital. Indeed, she claims to have followed protocol at all times and she is unable to identify how she could have contracted the virus. It is assumed that methods of environmental control were in place so the room was disinfected daily with sodium hypochlorite as prescribed.

A breach of protocol?

The director of the CDC (Center for Disease Control), Dr. Thomas R. Frieden believes that treatment protocols were not followed to the letter “Clearly there was a breach in protocol. We have the ability to prevent the spread of Ebola by caring safely for patients.”

CDCs are investigating in order to identify how Ms. Pham may have acquired the infection. Protocols are of course being examined. They would be sufficient to protect healthcare workers from infection by the virus if followed properly. Nevertheless, removing the protective equipment is always pointed out as a critical step. In Europe, another investigation is under way to understand how a Spanish nurse found herself in the same situation.

No reported case in Quebec, yet

A virus transmitted from computers to humans

October 8, 2014November 17, 2017Rémi Charlebois

Virus on my keyboard, really?

Did you know that your keyboard and mouse are covered with bacteria and viruses? This may sound obvious when we think about it. Using computers is very common and the risk to be infected seems banal. However, in certain environments such as hospitals this contamination could reveal critical.

In fact, many bacteria and virus breaks have been associated with computers. It’s the case for a hospital in Great Britain, where a study revealed that 42% of tested keyboards were contaminated with the MRSA bacteria, which was directly related to higher MRSA infections as compared to other hospitals where keyboard contamination was lower (1). Another study carried out in Great Britain found that keyboards had been a breeding-ground for the norovirus, which then lead to a break of gastro-enteritis. A virus transmitted from computers to humans… who would’ve thought about that!

Don’t panic, solutions exist!

First and unforgettable is hand washing. In order to limit bacteria and virus spreads, hand washing is essential. Then, to avoid washing our hands every time we use a computer, an alcohol-based antiseptic liquid would do the trick. If our hands are dirty, washing hands before touching the keyboard is also recommended. Finally, it is wise to disinfect your keyboard and mouse from time to time. A renowned researcher named William Rutala, or Bill for his friends, has demonstrated that computer keyboards do not seem to deteriorate after being cleaned 300 times with different disinfectant solutions.

Long story short, we often forget daily objects as being a breeding-ground for viruses and bacteria. For example, mobile phones are often neglected as well despite the fact that we touch them and constantly put them on our face.

But no need to become hypochondriac, it’s enough to follow basic preventive measures. In other words, make little changes and set frequent disinfections based on the risk associated with your environment.

A Brief History of Bleach

October 1, 2014November 17, 2017Gaétan Lanthier

Javel Underground, Paris, France (Bleach)

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).

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?

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.

A Wednesday Tale: Romans used to say: Automate your restrooms

September 24, 2014November 17, 2017Gaétan Lanthier

This is not really that the Romans would tell each other after a rough battle against the Gallic, but nowadays the battle is never ending and merciless against the irreducible microbes!

Certain bacteria are good for us

And yet, most of bacteria are good for us, simply think of yoghurts or biological products and you’ll see that not all bacteria must be eliminated!

In certain environments such as at home, it’s not necessary to eradicate all microbial activity on the surfaces. It’s still better do it in an operating room though!

Let’s talk about public restrooms

Whether it is in a clinic, at school, in a shopping mall, a restaurant, or even at the office, certain people are a bit reluctant to touch surfaces. And you?

Conceive the ideal restroom

In this room, you will find accessories that have been conceived based on 3 fundamental criteria:

Infection spread risk reduction
Consumption reduction (environment protection)
Comfort and well-being of the user

Ebola virus, Are we Ready?

September 18, 2014November 17, 2017Rémi Charlebois

We recently learned that Senegal has been hit by the Ebola epidemic outbreak in Africa. This makes Senegal the sixth country affected by the epidemic. The Center for Disease Control in Atlanta (CDC), said that the epidemic has a high chance of degenerating and that the outbreak may quickly spread outside Africa¹. Appealing for international aid, the scientific community is now seeing the epidemic on the verge of becoming an unprecedented pandemic.

Are we ready to deal with a global pandemic of Ebola?

Western public health agencies are meant reassuring. Our hospitals are better equipped to deal with potential cases. The Quebec ministry of health issued a policy of transparency and now discloses suspected cases in Quebec on its web site.

What to do to prevent the spread of Ebola virus in your institute?

Quebec Hospitals can refer to the official guide written by l’Institut national de santé publique du Québec. This fact sheet sets out the recommendations of the Comité sur les infections nosocomiales du Québec (CINQ) for Ebola virus disease prevention and control measures for Quebec hospitals. This document may be found here.

Use a 5% bleach solution (sodium hypochlorite) with a concentration of 5000 ppm to disinfect surfaces or objects contaminated by blood or other body fluids.

Use a 5000 ppm chlorine solution for the final disinfection.

Disinfection is, therefore, more than ever critical for limiting the spread of infection. The quality of the product is critical. Ebola is generally considered the world’s most dangerous viruses. Might as well use the best disinfectant!

Ebola, How to disinfect surfaces

September 11, 2014November 17, 2017Rémi Charlebois

The Ebola outbreak in West Africa is slowly becoming an epidemic that is spreading beyond Africa. Although the risk of transmission is relatively low, it is the largest ever recorded outbreak of Ebola. WHO, CDC and other NGOs have declared a state of emergency and fight tirelessly to limit the outbreak.

Importance of hygiene when it comes to Ebola

The debate today is polarized on the ethical use of experimental drugs. However, few media state of the propagation modes and the importance of hygiene against this virus. Although transmission is being achieved mainly by direct contact between two people, contaminated objects and surfaces can present a risk that is hard to assessed. Thus, the CDC and WHO suggest that objects in direct contact with the patient must be decontaminated properly and that medical or objects contaminated with body fluids must be incinerated.

Stabilized Sodium Hypochlorite

All well and good, but what product can be used to disinfect appropriately? Ebola Virus Outbreak Guidelines written by members of the Ministry of Public Health of Gabon suggest the use of sodium hypochlorite.

We do not always know the microbial threats we face, but if in doubt use a disinfectant caliber is required.

Cleaning in Hospitals (part 4)

September 9, 2014November 17, 2017Gaétan Lanthier

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!

Cleaning in Hospitals (part 3)

September 4, 2014November 17, 2017Gaétan Lanthier

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)

August 28, 2014November 17, 2017Gaétan Lanthier

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)

August 21, 2014November 17, 2017Gaétan Lanthier

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.
