Infection Control Remember to wash your hands! • Micro organisms- not visible to the naked eye • Beneficial-normal flora • Disease causing- pathogenic • Bacteria • Protozoa • Fungi • Viruses Bacteria • Prokaryotic cells that multiply rapidly. Classified by shape and by how they stain using the gram stain • Gram pos= purple, gram neg = red • Shape: – Round = cocci – Rods are bacilli – Corkscrew - spirilla • Bacteria are everywhere- they can live on any surface, with or without oxygen • In a compromised host, bacteria (even normal flora) can be the cause of life threatening diseases • Nosocomial infection: an infection acquired during a stay at the hospital Aseptic technique • Pathogens are everywhere, but they can be controlled or eliminated for a period of time by maintaining a clean, or aseptic, environment • Aseptic technique: practices or procedures that are used to ensure a clean, safe environment by controlling or eliminating contamination Handwashing using the correct technique • The single most important thing you can do to control infection. • Correct handwashing is the key to medical asepsis When do you wash your hands? • When first arriving to work. • Before performing each procedure on a patient. • During a procedure if your hands become contaminated. • Between each patient for whom you provide care. • After using the restroom. • After removing gloves from your hands. • Before eating. The single most important thing you can do to control infection? Wash your hands! So you’d think we’d all be washing our hands, right? WRONG • 1996 study showed only 12% of M.D.s washed their hands after every patient contact • Another study conformed M.D.s washed their hands between patients 9% of the time- when asked, they answered 50-95% • 1.8 million patients will contract nosocomial infections each year- 20,000 of these patients will die directly from infection. Another 70,000 will die from complications of a nosocomial infection • Nosocomial infections add 4.5 billion/year to health care costs • So- what’s the deal here? Doctors, nurses, healthcare workers are smart people- why don’t they wash their hands? How do you wash your hands? Let’s practice!
