Evaluation of risk factors linked to nosocomial infections in elderly hospitalized patients in the internal medicine and infectious diseases units in Kiffa hospital, Mauritania

Abstract

Objective: To determine the risk factors for nosocomial infections (NSIs) in elderly patients hospitalized in the Department of Internal Medicine and Infectious Diseases at the Kiffa Hospital Center. Patients and Methods: This was a cross-sectional and descriptive study conducted from January 1 to May 31, 2017. All patients hospitalized for at least 48 hours were included in the study. Result: A total of 73 elderly subjects were hospitalized for a prevalence of 24.17%. The M / F sex ratio was 2.31 and the average age was 75 ± 10 years with a range of (60-90 years). The majority of our patients (58.9%) had higher hospitalization was seven days. Fever associated with poor general condition were the main reason for consultation. Site respiratory infections accounted for 49.7% site monitoring urogenital (28.8%), gastrointestinal (16.4%) and skin (6.8%). Susceptibility factors were related to infections IN age (p = 0.00062), loss of autonomy (p = 0.0004), impaired general condition (p = 0.0004), the gates of ' entries (p = 0.0001), the pathologies poly (p = 0.02) and poly medication (p = 0.04). Overall mortality was 15.1% despite a support.  Conclusion: This work suggests that the elderly subjects in this context are widely exposed to high IN risk, even if, for technical reasons, microbiological examinations were not performed in our study population.
