Operational research (OR) published in 2023 revealed low utilisation and suboptimal quality of blood culture services at a tertiary hospital in Ghana. To address these, several interventions were implemented, including sensitisation of physicians, training of laboratory staff, use of automated incubation systems, and improved availability of laboratory consumables. To assess the impact of these interventions, we conducted a follow-up study in a cross-section of inpatients (n = 1080) with suspected bloodstream infections (BSI) admitted in 2024. There were three key changes. First, there was a five-fold increase in requests for blood culture from 8% pre-OR to 40% post-OR. Culture requests were more frequent from child health department (63%) and intensive care units (53%) compared to surgery department (15%). Second, there was a reduction in delays: time from hospital admission to culture request was reduced from 2 days to 1 day, and the laboratory turn-around time was reduced from 7 days to 5 days. Third, there was a marginal improvement (p = 0.692) in the quality of blood cultures: diagnostic yield improved from 7% to 10%, and the contamination rate was reduced from 16% to 14%. Achieving universal culture utilisation among eligible patients and lowering contamination rates will require a detailed gap analysis and targeted interventions.
