Factors associated with under-triage and emergency department length of stay in non-traumatic acute abdominal pain: a multicenter retrospective analysis in China.
Article in International 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
objectiveThis study aimed to identify independent predictors of under-triage among patients with non-traumatic acute abdominal pain (NAAP) and quantify their impact on emergency department length of stay (EDLOS).
methodsA multicenter retrospective study was conducted at three tertiary hospitals in China from December 2023 to May 2024, enrolling 769 patients with NAAP. Data collected included patient demographics, environmental factors, nurse characteristics, and clinical presentations. Binary logistic regression was employed to identify risk factors for under-triage, and multivariate linear regression was used to assess its association with EDLOS.
resultsThe incidence of under-triage was 16.38% (126/769). Multivariate analysis revealed that a history of hyperlipidemia (OR = 7.944), scleral icterus (OR = 5.731), persistent pain (OR = 4.116), and advanced age (OR = 2.447) were significant independent risk factors for under-triage (all P < 0.05). Conversely, higher nursing seniority (Senior Nurse: OR = 0.295; Charge Nurse: OR = 0.311) served as a protective factor. Furthermore, under-triage independently predicted operational inefficiency, prolonging EDLOS by approximately 310 min (B = 309.765, P < 0.001) after adjustment for confounders.
conclusionThis multicenter study demonstrates that under-triage in NAAP is associated with patient age, history of hyperlipidemia, higher nurse professional titles, and abdominal pain characteristics. Under-triage significantly prolongs EDLOS. These findings provide a foundation for understanding and mitigating under-triage through competency-based training and risk-stratified assessment protocols in emergency departments.
