BACKGROUND: Hospital-acquired bloodstream infections (BSI) are associated with high morbidity and mortality rates. This study was conducted to describe the outcomes and the prognosis of hospital-acquired BSI in the Critical Care Unit, Hospital Pakar Universiti Sains Malaysia (HPUSM), as well as to identify associated factors of treatment failure and mortality at 28 days.
METHODS: This prospective cohort study was conducted in the Critical Care Unit of HPUSM from September 2019 to March 2021. Eligible participants included patients with a positive blood culture recorded after 48 hours of admission to hospital.
RESULTS: There was a total of 250 patients, whose positive blood cultures were isolated. The main isolated organisms were Klebsiella pneumonia (23.6%), Pseudomonas spp. (19.2%), Escherichia coli (12.8%) and Acinetobacter sp. (9.2%). The mortality of hospital-acquired BSI was 27.6%. Multiple logistic regression analysis revealed that age [adjusted odds ratio (OR) = 1.06; 95% confidence interval (CI): 1.03, 1.09; p < 0.001], cases with extended-spectrum beta-lactamases (ESBL) (adjusted OR = 5.57; 95% CI: 2.04, 15.21; p = 0.001), with multidrug-resistant (MDR) organisms (adjusted OR = 14.70; 95% CI: 3.97, 54.48; p < 0.001) and those with a sequential organ failure assessment (SOFA) score > 11 (adjusted OR = 4.16; 95% CI: 1.31, 13.19; p = 0.015) had statistically significant associations with treatment failure. Factors significantly associated with 28-day mortality included age (adjusted OR: 1.06: 95% CI; 1.03, 1.09; p < 0.001), MDR organisms (adjusted OR = 14.70; 95% CI: 3.97, 54.48; p < 0.001) and SOFA score > 11 (adjusted OR = 4.16; 95% CI: 1.31, 13.19; p = 0.015).
CONCLUSION: The elderly, ESBL, MDR organisms and high SOFA scores were associated with treatment failure and 28-day mortality in hospital-acquired BSI.
