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
backgroundHospitals face increasing strain from rising clinical complexity and demand. Traditional resource allocation approaches often lack the granularity and timeliness needed for responsive planning. This study evaluates whether routinely collected electronic medical record data can be used to classify hospital inpatients into resource-based groups to support real-time planning and hospital-wide operational management.
methodsA retrospective analysis was conducted on 332,711 inpatient admissions to a quaternary public hospital in South Australia between January 2020 and January 2025. Patients were classified into one of four flow streams within 72 h of admission using a resource-based classification framework developed through a modified Delphi process and validated by clinical review. Summary statistics were used to assess differences in resource use across streams and to evaluate classification stability. Data quality limitations and documentation variability were also assessed.
resultsFlow streams demonstrated distinct differences in length of stay, diagnostic testing, consultations, and allied health input. The model showed strong initial stability, with fewer than 5% of patients changing streams during admission. Key data quality issues included inconsistent consultation documentation, underuse of structured fields, and retrospective overwriting of demographic information, affecting visibility of resource use. Despite these limitations, flow stream classification effectively differentiated patients by resource intensity and care complexity, offering a practical framework to support real-time hospital operations, complementing diagnosis-based groupings.
conclusionA structured classification model using routinely collected electronic medical record data can differentiate inpatient resource needs. Flow stream stratification offers a complementary approach to traditional coding-based systems and may help identify operational bottlenecks. With improved documentation and system integration, this approach could enhance hospital responsiveness, resource planning, and overall system performance.
