Prevalence and determinants of microbiologically unconfirmed healthcare-associated infections among hospitalized patients in Western Sierra Leone, 2024: a point prevalence survey.

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
Background: Healthcare-associated infections (HAIs) are a major global health problem. Gaps in their detection in low- and middle-income countries may be caused by limited surveillance capacity and lack of contextualized surveillance tools. Aim: This study aimed to evaluate the prevalence of HAIs and their determinants using contextually adapted HAI case definitions and tools. Methods: This was a cross-sectional multi-centre point prevalence survey among adults (≥18 years) and children (≥1 month) from 10 hospitals in Western Sierra Leone. The determinants of HAIs were derived using logistic regression analysis and adjusted relative risks with 95% confidence intervals (CIs) reported as a measure of association, and a Findings: Among the 10 hospitals, the mean hospital bed capacity was 109, and the average hand hygiene (HH) compliance was 30.6%. None of the hospitals had a functional bacteriology laboratory. Of the 319 eligible patients, 40 (12.5%) acquired HAIs, with 31 (77.5%) having suspected bloodstream infections. Cigarette smoking (adjusted odds ratio [aOR]: 3.764, 95% CI: 1.07-13.13, Conclusion: There was a high prevalence of microbiologically unconfirmed HAIs with patient-related factors and service delivery interventions as independent predictors. Fundamental gaps are low HH compliance and limited laboratory capacity to support HAI surveillance. We recommend sustained HH improvement initiatives, strengthening bacteriology capacity for HAI detection, and periodic point prevalence surveys on HAIs as an entry point.
