Nosocomial infections in long-term facilities

Area of Science:

• Infectious Diseases
• Geriatric Medicine
• Hospital Epidemiology

Background:

• Hospital-acquired infections (HAIs) pose a significant challenge in healthcare settings.
• Chronic-care facilities house vulnerable populations, including elderly males with multiple comorbidities.
• Understanding infection patterns in these facilities is crucial for targeted prevention strategies.

Purpose of the Study:

• To determine the incidence and prevalence of HAIs in intermediate-care and Nursing Home Care Units.
• To identify the most common sites of infection within these units.
• To explore the relationship between patient characteristics and infection susceptibility.

Main Methods:

• A 4-year retrospective study (1980-1983) analyzing infection rates.
• A 1-year prospective prevalence study involving monthly patient visits.
• Data collection on infection sites, patient demographics, and underlying conditions.

Main Results:

• The overall global infection rate was 3.86 per 1,000 patient care days.
• Lower respiratory tract infections were most frequent, followed by urinary tract infections, skin infections, and bacteremia.
• Elderly males with poor functional status and multiple diseases showed higher susceptibility.

Conclusions:

• The high incidence of nosocomial infections in chronic-care facilities is linked to patient functional status.
• Poor functional assessment increases susceptibility to infections, particularly lower respiratory and cutaneous infections.
• Targeted interventions for high-risk elderly patients are warranted to reduce HAI burden.
