Bloodstream infections at a tertiary hospital in the Gambia - a one-year retrospective study
(2025) In BMC Infectious Diseases 25(1).- Abstract
Introduction: Antimicrobial resistance is a significant global health concern, particularly in western Sub-Saharan Africa. This study describes causes of bloodstream infections and antimicrobial resistance at a tertiary hospital in The Gambia. Methods: This retrospective analysis included all blood cultures performed at the Edward Francis Small Teaching Hospital, Banjul, The Gambia, from September 2022 to August 2023. Blood culture positivity-rates and pathogens were described. Antimicrobial susceptibility testing was performed using disk diffusion following the Clinical & Laboratory Standards Institute guidelines. Results: A total of 645 patients had blood cultures drawn during the study period with 260 (40%) positive results.... (More)
Introduction: Antimicrobial resistance is a significant global health concern, particularly in western Sub-Saharan Africa. This study describes causes of bloodstream infections and antimicrobial resistance at a tertiary hospital in The Gambia. Methods: This retrospective analysis included all blood cultures performed at the Edward Francis Small Teaching Hospital, Banjul, The Gambia, from September 2022 to August 2023. Blood culture positivity-rates and pathogens were described. Antimicrobial susceptibility testing was performed using disk diffusion following the Clinical & Laboratory Standards Institute guidelines. Results: A total of 645 patients had blood cultures drawn during the study period with 260 (40%) positive results. Contaminants were identified in 28 cases (4%). The majority were drawn from neonatal or paediatric patients (360/645, 56%) and overall primarily in intensive care units (406/645, 63%). The median age was 3 years (interquartile range 0–31 years) and 46% were female. The most common pathogens were Staphylococcus aureus 106/260 (41%), Klebsiella spp. 41/260 (16%), other bacteria within the Enterobacterales order 33/260 (13%), Pseudomonas spp. 22/260 (8%) and Acinetobacter spp. 19/260 (7%). Methicillin-resistant S. aureus (MRSA) was seen in 34/58 (59%) tested. Extended-spectrum beta-lactamases (ESBL) were seen in 36/40 (90%) of Klebsiella spp. and in 16/28 (57%) of other bacteria within the Enterobacterales order. Acquired antibiotic resistance, beyond wild-type, was reported in 17/20 (85%) of Pseudomonas spp. and 16/19 (84%) of Acinetobacter spp. Conclusion: Overall, blood culture positivity rates were high, indicating restrictive testing suggesting that sample collection were restricted to mainly critically ill, neonatal or paediatric patients. Nonetheless, our data suggests a high proportion of bloodstream infections due to multi-drug resistant pathogens, including MRSA and ESBL-Enterobacterales. Importantly, generalisability of findings beyond this tertiary hospital setting remains restricted. However, our findings demonstrate a need for improved diagnostic stewardship and ongoing surveillance to provide robust evidence-based data to inform antimicrobial resistance interventions.
