[Infection epidemiology in gerontology centres].

Area of Science:

• Gerontology
• Infectious Diseases
• Epidemiology

Context:

• Gerontology centers (GCs) face significant challenges with infection processes, contributing to mortality and exacerbating chronic conditions.
• An epidemiological surveillance system was established to quantify and understand the patterns of infections within these facilities.
• The study focused on four GCs over a four-year period (2006-2009).

Purpose:

• To determine the prevalence and incidence of nosocomial infections in gerontology centers.
• To identify common infection types, locations, and associated risk factors.
• To inform the development of targeted intervention and prevention strategies.

Summary:

• Prevalence of infections in GCs ranged from 4.8% to 6.44%.
• Infection incidence density was 3.45-5.77 per 1,000 resident days.
• Respiratory infections were most common, significantly associated with dysphagia, malnutrition, and COPD; urinary infections showed no significant risk factor correlation.

Impact:

• Findings underscore the substantial burden of nosocomial infections in GCs.
• Results emphasize the critical need for implementing effective infection control and prevention programs.
• The study provides data to guide resource allocation and policy development for improving resident safety.
