Reducing surgical site infections in paediatric cardiac surgery in a resource-constrained setting: a quality improvement initiative.
Article in BMJ open quality, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
problemA newly established congenital cardiac surgery programme in a low-resource setting identified a high early surgical site infection (SSI) rate of 23% during the first 3 months, reflecting variation associated with small case volumes and evolving systems.
backgroundGlobal paediatric cardiac SSI rates range from 0.25% to 6%, but can exceed 20% in low and middle-income countries due to workflow variability, resource constraints and patient-related risk factors. Most SSI prevention bundles originate from high-income settings and require contextual adaptation. Quality improvement (QI) methods can strengthen reliability when tailored to local systems.
methodsA learning health system approach was used, combining process mapping, root cause analysis, a key driver diagram and four sequential Plan Do Study Act cycles. Interventions targeted reliability across the perioperative pathway. The primary outcome was SSI rate per 100 surgeries. Process measures included training completion, preoperative risk screening, wound documentation and structured review of moderate and severe infections. Balancing measures included length of stay, mortality rate, case cancellation rate and readmissions. Interventions included strengthened sterilisation and risk screening practices, a nurse-led wound clinic with 30-day follow-up and training in aseptic technique and hand hygiene.
resultsAmong 500 surgeries, 31 SSIs occurred. SSI rates decreased from 12 to 6 per 100 surgeries and reached 2 per 100 surgeries, before increasing to 6 then 5 per 100 surgeries in later phases. Process reliability improved across all measures, while balancing measures remained stable. Following sustainability actions, environmental cleaning compliance improved from 20% to 85% and hand hygiene from 45% to 90%.
conclusionQI interventions were associated with reduced SSI rates, although sustained benchmark performance was not achieved. Continued monitoring and behaviour-focused strategies will guide further improvement.
