Background:Healthcare-associated infections are a major cause of mortality worldwide, especially in intensive care units where severely ill patients have limited physical space. Aims: To investigate the incidence, microbial aetiology, antimicrobial resistance profile, and mortality rate of healthcareassociated infections in intensive care units in the Islamic Republic of Iran.Methods:This observational study retrospectively reviewed the medical records of 1722 intensive care units patients with confirmed healthcare-associated infections at hospitals affiliated with Mashhad University of Medical Sciences in 2017–2019. Data was analysed using SPSS for Windows version 11. Categorical variables were described using frequency and percentage, whereas continuous variables were defined using mean (standard deviation) with 95% confidence interval (CI) for precision. Logistic regression analysis was used to estimate crude odds ratio (OR) and adjusted OR (AOR) with 95% CI, and to identify univariate and multivariate predictors of healthcare-associated infection mortality.Results:In total, 4077 pathogens were isolated, yielding a healthcare-associated infection incidence rate of 22.1%. The most common microorganisms were Acinetobacter spp. (25.0%), Klebsiella spp. (15.1%), Staphylococcus spp. (14.0%), and Candida spp. (12.3%). Ventilator-associated events (39.5%), urinary tract infections (22.7%), and bloodstream infections (14.8%) were the main types of infection. Comorbidities, skin and soft tissue infections, and infections with Acinetobacter spp., Klebsiella spp., Pseudomonas spp., and Candida spp. were significantly associated with higher mortality among intensive care unit patients. Gram-positive bacteria were most resistant to ciprofloxacin (49.2%), clindamycin (38.0%), and erythromycin (37.1%). Gram-negative bacteria were most resistant to ceftazidime (71.0%), ciprofloxacin (65.2%), and cefotaxime (60.5%). The overall mortality rate was 45.2%.Conclusion:Healthcare-associated infections in nearly half of intensive care unit patients were fatal, especially when caused by Acinetobacter spp., Klebsiella spp., Pseudomonas spp., or Candida spp. Therefore, effective strategies must be implemented to combat antibiotic-resistant bacteria, along with stricter adherence to infection control programmes.
