Abstract

Background: Surveillance of health care-associated infections (HCAIs) is an integral part of infection control programmes, especially in intensive care units (ICUs). Device-associated infections (DAIs) are a major threat to patient safety. Aim: To measure DAI rates in ICUs. Methods: Central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia (VAP), and cathe-ter-associated urinary tract infection (CAUTI) were assessed in the ICUs of 4 tertiary-care teaching hospitals in Tehran, Islamic Republic of Iran. Results: The incidence rate of CLABSI, VAP and CAUTI was 10.20, 21.08 and 7.42 per 1000 device-days, respectively. The utilization ratio for central lines, ventilators and urinary catheters was 0.62, 0.47, and 0.84, respectively. The most common organisms were Acinetobacter (33.5%) and Klebsiella (19.0%). Sixty to eighty percent of Enterobacteriaceae were extend-ed-spectrum beta-lactamase producing. About half of Pseudomonas aeruginosa isolates were resistant to piperacillin/ tazobactam and carbapenem. Acinetobacter resistance rate to ampicillin/sulbactam and carbapenem was 70–80%. The prevalence of methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus was 84.6% and 83.3%, respectively. Conclusions: This study showed high incidence rates of DAIs and resistant organisms, and appropriate interventions are necessary to reduce these rates. © World Health Organization (WHO) 2019.
