Antibiotics to treat healthcare-associated infections (HCAIs) contribute to a substantial proportion of drug expenditure in intensive care units (ICUs). Our study aimed to determine the common HCAIs in our hospital ICU, to assess the antibiotics prescribed and the mean antibiotic cost per HCAI. All adult patients, admitted to the ICU over a 1-year period, were included in the study. HCAIs were determined according to CDC definition. The incidence of HCAIs in the ICU was 16%. Ventilator associated pneumonia (50%) was the most common HCAI, followed by urinary tract infection (35.6%). The total cost of antibiotic treatment for HCAIs in ICU over a 1-year period was approximately Rs. 2 million (US$32,000); the mean antibiotic cost per HCAI was calculated as Rs. 17,000 (US$255). HCAIs in the ICU thus put a significant economic burden on the patient and the healthcare network and should be prevented by implementing recommended infection control guidelines.
