Hospital-Acquired Bloodstream Infections in the Adult Intensive Care Unit at Prince Mohammed bin Abdulaziz Hospital, Riyadh, Saudi Arabia.

Abstract

Introduction Hospital-acquired infections, also called nosocomial infections, are infectious diseases acquired in healthcare facilities at least 48 hours after admission and can't be present at the time of admission. Nosocomial bloodstream infection is a serious medical complication from hospitalization, and it can be potentially preventable by taking certain precautions. Aim The aim of this study is to determine the prevalence of central line-related bloodstream infections (CLABSI) with different organisms between January 2022 and February 2024 at the intensive care unit (ICU) at Prince Mohammed bin Abdulaziz Hospital, Riyadh, Saudi Arabia. Patients and methods This retrospective cross-sectional study was conducted among ICU adult patients. The data were collected from medical and infection control records. All data for intensive care patients with positive blood cultures, except for the pediatric age group, were collected. Data were tabulated and cleaned in MS Excel, and subsequent data analyses were performed in IBM SPSS Statistics for Windows, Version 26 (Released 2019; IBM Corp., Armonk, New York, United States). Results Data from 21 patients were collected and analyzed. The mean age of the participants was 62.9 (SD 15.1) years.Femaleparticipants (61.9% (13)) were higher than males(38.1% (8)). All patients were inserted with a non-tunneled central venous catheter (CVC). The mortality rate was 76.2% (16). Vancomycin-resistant enterococci (VRE) was the most commonly detected organism in seven cultures(33.3%), followed by Candida species in six cultures(28.6%). Candida species were prevalent in younger patients (p=0.021) and those sensitive to medication (p=0.015). Survival analyses between age, gender, and organisms yielded insignificant results (p>0.05). Conclusion The major sources of bloodstream infection among adult ICU patients were VRE and Candida species. Mortality was common in this population, particularly among patients who were resistant to medication. Hence, strategies to reduce hospital-acquired bloodstream infections are warranted.
