摘要

Introduction: Nosocomial infections imply a public health problem, and, in geriatric patients, they have specific features in geriatric healthcare facilities and services. Prevalence studies have proven to be effective in monitoring nosocomial infections and reducing costs. Objectives: To analyze prevalence, etiologies, and localizations of nosocomial infections in a convalescent care hospital. To quantify risk factors (venous and urinary catheters) and antibiotic prescription. Materials and methods: A prevalence study was conducted in a convalescent care geriatric unit. Age, reason for hospitalization, prevalence and etiologies of infections, risk factors, and antibiotic treatment of all inpatients older than 65 years, were registered on May 18, 2018. Results: 106 patients were included (mean age: 82.8 ± 8.4), 62.3% women, 25.5% with an active infection (urinary tract infections 20.6%, lower respiratory infections 20.6%). Prevalence of nosocomial infections was 10.4% (45.5% urinary infections, 9.1% lower respiratory infections). Palliative care ward had the highest prevalence of infections and nosocomial infections (35.7% and 14.3% respectively). Non-neurological rehabilitation unit had a prevalence of infections of 27% (10.8% of patients, with nosocomial infections). A 32.1% of patients received antibiotics. Amoxicilin-clavulanate and levofloxacin were the most frequently prescribed antibiotics (11.8% both). A 17% of patients had peripheral venous catheters and 11% urinary catheters. Conclusion: Prevalence of nosocomial infections was 10.4%. Urinary tract infections were the most common nosocomial infections. Palliative care ward had the highest prevalence of infections. Amoxicilin-clavulanate and levofloxacin were the most frequently prescribed antibiotics.
