The Impact of Urinalysis Turnaround Times on Patient Disposition in the Emergency Department.
Article in The western journal of 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
introductionDiagnostic efficiency in the emergency department (ED) is crucial for workflow. Among these, urinalysis (UA) is a key test for abdominopelvic complaints. Prolonged UA turnaround times can extend patient length of stay and reduce patient satisfaction, highlighting the need for improvement. In this study qw sought to measure the correlation between UA turnaround times and time to disposition.
methodsWe conducted a retrospective analysis of discharged ED patients with abdominopelvic complaints who had a UA ordered between January-August 2022. Electronic health records data included UA order-to-result time, urine human chorionic gonadotropin (hCG), time to disposition, and complete blood count (CBC) turnaround time as a venipuncture comparator. Spearman correlation coefficients assessed associations between lab processing times and time to disposition.
resultsAmong 6,708 discharged patients included in the study, 3,795 presented with abdominopelvic complaints. In this subgroup, 3,688 UAs, 1,285 urine hCG tests, and 2,966 CBCs were obtained. Median times from UA order-to-specimen receipt and result were 65 (IQR 29-138) and 92 (53-168) minutes, respectively. A modest positive correlation was observed between UA order-to-result time and time to disposition (ρ = 0.46), relative to CBC order-to-result time (ρ = 0.29). The relationship was slightly weaker for urine hCG (ρ = 0.35). Laboratory turnaround times showed minimal correlation with ED time to disposition (UA ρ = 0.04; urine hCG ρ = 0.03; CBC ρ = 0.09).
conclusionUrinalysis acquisition and processing times are modestly correlated with time to disposition in patients with abdominopelvic complaints. Reducing collection time for UA and urine hCG tests may improve throughput for this patient cohort.
