Evaluation of Hospital Acquired Infections in Adult Patients in Intensive Care Unit: Retrospective Study

Abstract

Objective: It is very important to determine infections and etiologic organisms in intensive care unit, in order to take necessary precautions and treat them successfully. Infections developing in intensive care units, result in very high morbidity, mortality and massive increases in hospitalization costs. In this study, it has been aimed to determine frequency, general properties and etiology of lower respiratory tract, urinary tract and blood stream infections developed in intensive care unit and compare these data with the national data. Material and Methods: Between January 2016 and December 2019, 178 infections, developed in an intensive care unit having 51 adult patient beds, were evaluated, retrospectively. Lower respiratory tract, urinary tract and bloodstream infections and causative organisms were investigated. Patients aged under 18, who had immunosupressive diseases and who had infections developed after surgical interventions were excluded. Results: Eigthyfive female, 86 male patients were enrolled, mean age was 72.5±14 years. Infection rate for a thousand hospitalization days in lower respiratory tract infections was 4.5, urinary tract infections was 0.3 and bloodstream infections was 0.2. Rate of ventilator-associated pneumonia was higher than Turkish National Data. Urinary tract and blood stream infections rate were less than expected (p<0.05). Frequent causative organisms were gram negative bacterias such as Acinetobacter baumannii, Klebsiella pneumoniae and Escherichia coli. Conclusion: Determining infections and causative organisms developing in intensive care unit and comparing their frequencies to national data will be useful to prevent hospital acquired infections and take precautions according to.
