Are nosocomial infections preventable?

Based on these estimates, we consider at least 20% of all nosocomial infections as probably preventable, and hope that this overview will stimulate further research on feasible and cost-effective prevention of nosocomial infections for daily practice.

How can normal flora cause nosocomial infections?

The organisms causing most nosocomial infections usually come from the patient’s normal flora of the skin and mucous membranes (endogenous flora), when host factors that alter susceptibility to infection permit these organisms to behave as pathogens (6).

What is the hospital acquired infection?

Hospital-acquired infections, also known as healthcare-associated infections (HAI), are nosocomially acquired infections that are typically not present or might be incubating at the time of admission. These infections are usually acquired after hospitalization and manifest 48 hours after admission to the hospital.

Certain underlying diseases, procedures, hospital services, and categories of age, sex, race, and urgency of admission were all found to be significant risk factors for nosocomial infection.

What is the most effective means in reducing nosocomial infections?

Nosocomial infections kill between 90,000 and 100,000 patients per year. Cost of each case infection has been estimated at between $15,000 and $25,000. Handwashing remains the most effective way to reduce incidence of nosocomial infections.

What does nosocomial infection mean?

A nosocomial infection is contracted because of an infection or toxin that exists in a certain location, such as a hospital. People now use nosocomial infections interchangeably with the terms health-care associated infections (HAIs) and hospital-acquired infections.

Who is at risk for nosocomial infections?

All hospitalized patients are susceptible to contracting a nosocomial infection. Some patients are at greater risk than others-young children, the elderly, and persons with compromised immune systems are more likely to get an infection.

What are the 3 methods of infection control?

There are three types of transmission-based precautions: contact, droplet, and airborne. Contact precautions are used in addition to standard precautions when caring for patients with known or suspected diseases that are spread by direct or indirect contact.
