Abstract

Backround: Hospital-acquired
infections (HAIs) are issues for not only patients who get treatment in the intensive
care unit but also for patients who are being treated in internal medicine and
surgical departments. HAIs cause functional disorders, less life quality or even
death. The aim of this study was to investigate the
prevalence of HAIs, distribution of the infections, and isolated microorganisms
in units other than the intensive care units (ICU).

Materials and Methods: Data of the patients who developed
hospital infections between January 2014 and December 2017 were evaluated
retrospectively. The McCabe score was used for categorical evaluation.

Results: The overall HAI rate was 0.17%. Of these, 619 (53.1%) occurred in departments
other than the intensive care units. The most common HAI was surgical site
infection (n: 223, 36%) followed by urinary tract infection (n: 176, 28.4%) and
pneumonia (n: 125, 20.2%). According to patients' comorbid disease status, 48%
(n: 297) was McCabe class 1, 30% (n: 186) was McCabe class 2, and 22% (n:136) was
McCabe is class 3. In 85 (13.7%) of 619 HAI cases, the agent could not be
isolated, and the diagnosis of HAI was based on clinical findings.
Four-hundred-ninety-two bacteria were isolated and 409 (83.1%) were gram-negative
whereas 83 (16.9%) were gram-positive.

Conclusions: HAIs are important health problems not only for patients in intensive care
units, but also for patients who are treated in services. It was thought that
the characteristics of the concomitant diseases need to be taken into
consideration in preventing hospital infections.
