Disinfection of surfaces and transmission of infections in medical units:

There are three key components in the chain of infection:

1. The first component / subject is susceptible, namely the patient. Especially those patients with low immunity or patients who follow invasive procedures that require prolonged stay in hospitals.

2. The second is the source of pathogens, such as positive patients, environmental surfaces, devices or water and air.

3. The third is the mode of transmission, ie the path through which the source of pathogens and sensitive subjects is connected. It can be further divided into direct contact and indirect contact, such as contact surfaces, which present a high risk of contamination. Healthcare associated infections (HAIs) are one of the leading causes of mortality in healthcare in the US or other countries. Associated infections are also responsible for the substantial costs of healthcare. With the development of drug-resistant microorganisms, the prevention of these infections becomes even more important.

The role of high touch surfaces in HAI:

The chances of contracting infections are significantly higher if negative patients were placed in a room previously occupied by positive patients. Studies show that pathogens can survive on almost all types of surfaces, hours, weeks and even months. There is a direct epidemiological relationship between surface pathogens (environmental surfaces and surfaces of medical devices) and elevated HAIs, including methicillin-resistant staphylococcus aureus (MRSA), Vancomycin-resistant enterococcus (VRE), Acinetium difficile and Cl (difficult).

Hand hygiene and disinfection of surfaces

The importance of hand hygiene in reducing the risk of infection has been discovered, developed and disciplined over the last 100 years. Without proper cleaning and disinfection of the environment, the beneficial effects of hand hygiene are compromised due to the frequency of use of surfaces that reach the hands and the persistence of pathogens on surfaces. Studies show that contact with environmental surfaces, including medical devices, was sufficient to contaminate the hands of doctors or nurses, as was direct contact with patients.

How to choose a suitable surface disinfectant:

The most used are disinfectant wipes, sprays and concentrated disinfectants.

There are 4 key features in choosing a suitable surface disinfectant:

1. Contact time or station time. It is the time required for effective disinfection of pathogens. The main products on the market have a contact time less than or equal to 3 minutes to meet the practical needs of the clinical environments.

2. Wide spectrum disinfectants. Bactericides, virucides and mycobactericides are the most common, but also fungicidal action should not be overlooked. According to studies, mushrooms accounted for between 13% and 30% of HAI.

3. Cleaning properties. Organic waste such as blood, sage and body fluids can transmit and retain different pathogens. Choosing a disinfectant with good cleaning properties is helpful.

4. Compatibility of materials. Medical device suppliers and disinfectant manufacturers work together. They choose materials that are suitable and durable for ordinary disinfectants with good chemical compatibility. However, the leaflet of the disinfectant must be checked / read before use.

We offer you a wide range of medical disinfectants for surfaces and for hands, microaeroflora and instrumentation.
