Infection Control Systems Human Healthcare
NOSOCOMIAL INFECTIONS
According to the CDC report,on average, in the US,one Patient gets a Healthcare-associated infection out of 25 admitted.
And 1 patient died out of 9 infected.
CAUSE OF NOSOCOMIAL INFECTIONS
• Patient with Compromised Immunity
• Multidrug-Resistant Organisms (MDRO)
• Hospital Environment & BIOFILM
• Cleanliness & hygiene Standards
• Barrier less Centralised HVAC
• Ban on Formaldehyde Fumigation
• Surgical Instruments Sanitisation
• Implants & Transplants
BIOFILM is a source of constant contamination created by an accumulation of bacteria, which develops a protective matrix made of Organic polymers (EPS) polyacrylamide, proteins,DNA, lipids,etc. Biofilms hove a protective matrix that protects bacteria, making them more resistant to internationalizing and disinfection agents.
More than air-born atmospheric contaminates,hospitals have hidden surfaces inaccessible for conventional cleaning.Inside surgical equipment,under the bed, behind furniture, walls,ceilings,AC ducts,and light fixtures are usually impossible to clean. These surfaces are the source of biofilm formation. Biofilms are the protective layer underneath which bacteria and viruses hide and multiply.
FALLACIES
• Conventinal chemical cleaning is enough to get rid surface micro- organisms growing inder the Biofilm.
• Chemical cleaning can remove biofilm
FACTS
• 80% of the microbes on the planet live and multiply under the self-developed protective layers of biofilms
• More than 50% of the surface areas are not possible to clean.
• Microorganisms under Biofilsm are 10 to 1,000, times more resistant to animicrobial agents & biocides
• Surfaces that are not thoroughly treated are bound to form Biofilsm/p>
Treatment which is capable of oxidizing the Biofilms & bio growth underneath.
The technique should be the point of source.
