Antibiotic prescribing appropriateness for urinary tract infections in a tertiary emergency department: a retrospective cohort study.
Article in BMC emergency medicine, 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
introductionAntibiotic misuse in emergency departments (EDs) drives antimicrobial resistance and adverse outcomes. This study assessed ED antibiotic prescribing adherence to hospital UTI guidelines at King Abdulaziz Medical City, Jeddah, Saudi Arabia, and identified predictors of non-adherence.
methodsThis retrospective cohort study included consecutive patients undergoing urine culture in the ED between September and December 2021. Two independent clinical pharmacists assessed appropriateness using the validated National Antimicrobial Prescribing Survey (NAPS) tool against the Ministry of National Guard Health Affairs (MNGHA) 2022 UTI guidelines across four domains: drug selection, dose, route, and duration. Two binary logistic regression models identified independent predictors of non-adherence and 30-day ED revisit.
resultsOf 346 patients (78.0% female), 184 (53.2%) had positive cultures and 216 (62.4%) received antibiotics. Overall, 153 (44.2%) had guideline-adherent management and 189 (54.6%) were non-adherent; among antibiotic-treated patients, only 31 (14.4%) received a guideline-adherent prescription. Leading non-adherence reasons were inappropriate drug selection (31.7%), overtreatment (29.6%), and resistance mismatch (13.8%). Positive culture (adjusted OR 1.89, p = 0.018) and UTI indication (adjusted OR 2.79, p < 0.001) independently predicted non-adherence. Positive-culture patients had higher 30-day ED revisit rates (26.6% vs. 14.8%, p = 0.008). Independent predictors of revisit were non-adherent prescribing (OR 2.20), pediatric age (OR 3.63), and prior antibiotic use (OR 2.91).
conclusionsAntibiotic prescribing for UTIs in this tertiary ED demonstrated significant non-adherence to MNGHA guidelines, attributable primarily to inappropriate drug selection and overtreatment of culture-negative patients, and was independently associated with 30-day ED revisit. Electronic decision support, pharmacist-led culture follow-up, and local antibiogram updates are needed to improve prescribing quality. Addressing these gaps is an actionable priority for antimicrobial stewardship in resource-limited ED settings and is directly relevant to curbing antimicrobial resistance and improving patient safety. As a single-centre retrospective study restricted to culture-ordered patients, findings may not generalise to all ED UTI presentations.
