Nosocomial infections, also known as healthcare-associated infections (HAIs), are infections acquired in hospitals or other healthcare facilities. These infections are typically not present or incubating at the time of a patient's admission. Here are the criteria for identifying nosocomial infection
Timing: The infection must occur at least 48-72 hours after admission. Alternatively, the infection could manifest within 10-30 days after discharge, particularly if it is related to a surgical procedure
Location:The infection occurs in a hospital, nursing home, rehabilitation center, outpatient clinic, or other healthcare facility.
Microbiological Evidence:The infection is confirmed by laboratory tests such as cultures, serological tests, or other microbiological evidence.
Clinical Symptoms:The patient presents symptoms and signs consistent with an infection (e.g., fever, redness, swelling, pain, discharge, etc.).
