Drug use patterns at a Kenyan referral hospital: A cross-sectional study using WHO core indicators.
Article in PloS one, 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
backgroundSuboptimal medicine use practices remain a major global health challenge, particularly in low- and middle-income countries, where it contributes to increased healthcare costs, and the growing burden of antimicrobial resistance. This study aimed to evaluate drug use patterns at Thika Level 5 Hospital in Kenya using World Health Organization (WHO) core drug use indicators.
methodsA facility-based cross-sectional study was conducted in the outpatient department. Data were collected from 600 prescriptions, 100 patient encounters, and facility-level assessments using standardized WHO/INRUD data collection tools. Descriptive and inferential analyses were performed using IBM SPSS Statistics (version 29), and findings were descriptively compared with WHO reference standards.
resultsThe mean number of drugs per prescription was 3.18, which was higher than the WHO recommended range of 1.6-1.8. Generic prescribing was 45.86% while antibiotic prescribing was observed in 58.7% of encounters. Injection use was 13.0% and 76.86% of prescribed medicines were from the Essential Medicines List (EML). Patient-care indicators showed a mean consultation time of 4.26 minutes and a mean dispensing time of 122.8 seconds, which was below the WHO- recommended reference value. Only 30.0% of medicines were adequately labelled, and 44.0% of patients demonstrated complete knowledge of their medications. Significant associations were observed between dispensing time and patient knowledge (p = 0.001), as well as between labelling adequacy and patient understanding (p < 0.001). In contrast, all facility indicators met WHO standards, with full availability of essential medicines, treatment guidelines, and stock records.
conclusionDespite strong facility readiness, important gaps were identified in prescribing and patient-care practices. These findings highlight opportunities for interventions aimed at strengthening antimicrobial stewardship initiatives, promoting generic prescribing, improving dispensing practices, and enhancing patient counselling to support improved medicine use practices..
