A hospital-acquired infection, also known as a nosocomial infection (from the Greek nosokomeion, meaning "hospital"), is an infection that is acquired in a hospital or other healthcare facility. [1] To emphasize both hospital and nonhospital settings, it is sometimes instead called a healthcare-associated infection. [2]
Hospital acquired pneumonia is the second most common nosocomial infection (after urinary tract infections) and accounts for 15–20% of the total. [ 1 ] [ 2 ] [ 3 ] It is the most common cause of death among nosocomial infections and is the primary cause of death in intensive care units .
Infection prevention and control is the discipline concerned with preventing healthcare-associated infections; a practical rather than academic sub-discipline of epidemiology. In Northern Europe , infection prevention and control is expanded from healthcare into a component in public health , known as "infection protection" ( smittevern ...
Healthcare-associated infections (HAIs), often contracted in a hospital are infections that patients acquire during the course of receiving healthcare treatment for other conditions. The most dangerous show antibiotic resistance.
As a result, throughout the world, they are the major cause of life-threatening nosocomial or hospital-acquired infections in immunocompromised and critically ill patients who are most at risk. [3] P. aeruginosa and S. aureus are some of the most ubiquitous pathogens in biofilms found in healthcare. [4]
This type of infection is one that is transmitted from a health care worker to a patient. A nosocomial infection is also one that occurs in a health care setting. Nosocomial infections are those that are acquired during a hospital stay. Lastly, a community-acquired infection is one in which the infection is acquired from a whole community. [58]
Pneumonia is the most common hospital-acquired infection that causes death. [29] Before the advent of antibiotics, mortality was typically 30% in those that were hospitalized. [22] However, for those whose lung condition deteriorates within 72 hours, the problem is usually due to sepsis. [41]
APIC strives to limit the cause and spread of hospital-acquired (HAIs) infections by: Collection, and analysis of healthcare data to monitor hospital-acquired infection trends, to plan interventions with other established public health agencies. Prevention of nosocomial infections by identifying sources of infections and stopping their ...
