1 · What the graph read from it

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.

2 · The registry

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

backgroundEmergency department (ED) crowding is a global challenge, presumably aggravated by low-acuity utilization. Various patient streaming interventions have been implemented in EDs to reduce potentially unnecessary utilization and improve care coordination and patient throughput. This systematic review examined the effectiveness and safety of ED-based streaming for low-acuity patients.

methodsA search of MEDLINE, EMBASE, CINAHL, and Cochrane Library databases was conducted up to December 2, 2025. Screening and data extraction were performed in duplicate. RCTs, non-randomized controlled trials, interrupted time series, and before-after studies on general practitioner (GP) streaming, ED streaming, and urgent care (UC) streaming for low-acuity utilizers were eligible. We assessed outcomes related to care effectiveness, patient safety, and cost-effectiveness. Random-effects meta-analyses were performed. Risk of bias was assessed by the Effective Public Health Practice Project tool.

resultsWe included 137 publications reporting on 119 research projects. Meta-analyses showed higher proportions of cases managed in alternative tracks for GP streaming (0.32; CI 0.17;0.51) compared to ED streaming (0.25; CI 0.15;0.37). Both GP and ED streaming demonstrated reductions in length of stay, particularly for low-acuity patients (GP: SMD − 0.85; CI -1.37;-0.33; ED: SMD − 0.39; CI -0.56;-0.22). Safety outcomes, including leaving without being seen and unplanned ED reattendances, generally improved or were unchanged. The impact on ED utilization and cost-effectiveness remained inconclusive due to inconsistent evidence. There was high variability across outcomes, likely due to diverse context factors and multifaceted interventions.

conclusionsThis review provides a comprehensive synthesis of various ED-based streaming interventions for low-acuity patients, with effect estimation by meta-analyses. Results suggest that GP and ED streaming improve care without compromising safety, with indications of a greater potential for alternative care with GP streaming. The predominance of observational studies with potential biases and unexplained heterogeneity, however, results in very low overall certainty of the evidence. REGISTRATION: PROSPERO CRD42022355935.
