Device-Associated Nosocomial Infections Developing in the Intensive Care Units: A Five-Year Evaluation

Abstract

Objective

We analyzed the rates of invasive device-associated nosocomial infections (IDANIs), ventilator-associated pneumonia (VAP), central venous catheter-related bloodstream infections (CVCR-BSI), catheter-associated urinary tract infections (CR-UTI) and their microorganism profiles.

Material and Methods

Patients who were followed up in Konya Training and Research Hospital ICUs between 01.01.2016 and 31.12.2020 for a period of 5 years were included in the study. IDANIs were defined by the Centers for Disease Control (CDC) and the National Nosocomial Infections Surveillance Network (NNISN) criteria.

Results

Health-care associated infections (HCAIs) were detected in 1556 of the 34972 patients over the five-year period in ICUs.510 of the HCAIs were IDANIs.  The rates of invasive device utilization were 0,28 for mechanical ventilators, 0,39 for central venous catheters and 0,85 for urethral catheters. The device-associated nosocomial infection rates for ventilator-associated pneumonia (VAP) 2.7%, central venous catheter-related bloodstream infections (CVCR-BSI) 17.9%, catheter-related urinary tract infections (CR-UTI) 12%. Of these infections, Klebsiella pneumoniae was the most frequent pathogen.

Conclusion

IDANIs are seen more frequently in intensive care units than in other units. Patients who developed IDANI had longer durations of ICU hospitalizations and more often had to use invasive procedures such as mechanical ventilators, central and urinary catheters.
