Association of Emergency Department Length of Stay and Hospital Mortality in Patients Under Investigation for COVID-19.
Article in Open access emergency medicine : OAEM, 2024. 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
Objective: We aimed to determine the association between hospital mortality of patients under investigation (PUI) for COVID-19 and emergency department length of stay (EDLOS). Patients and Methods: A retrospective study was conducted from April 3, 2020 to April 2, 2022. Adult PUI who presented with both clinical and epidemiological risk factors for COVID-19 disease and underwent sample collection with nasal swab for reverse transcription polymerase chain reaction were included in the study. The factors associated with EDLOS and hospital mortality were investigated using univariate logistic regression and multivariate logistic regression analyses. Results: A total of 961 PUI were enrolled that included 836 (87%) non-COVID-19 patients. The median (interquartile range [IQR]) EDLOS durations for 7-day and 30-day mortality of all PUI were 3.1 hours (2.1,4.3, P = 0.231) and 3.2 hours (2.1,4.3, P = 0.653). Multivariate logistic regression analysis revealed that the significant factors associated with EDLOS longer than 4 hours were consultation of three departments (adjusted odds ratio (aOR) 27.3, 95% CI 2.42-309.71, P = 0.007), emergency severity index (ESI) level 3 (aOR 2.31, 95% CI 1.37-3.9), investigations >2 (aOR 2.62, 95% CI 1.62-4.25), nebulization (aOR 2.34, 95% CI 1.39-3.96), administration of intravenous fluid (aOR 2.62, 95% CI 1.59-4.33), performing ≥1 procedure (aOR 3.35, 95% CI 1.51-7.43), and discharged patients (aOR 2.13, 95% CI 1.02-4.48). Conclusion: The significant factors associated with prolonged EDLOS in PUI included consultation of three departments, ESI level 3, investigations >2, ED treatment, ED procedures, and discharged patients. The median times of EDLOS and hospital LOS were 3.2 hours and 5.7 days. The EDLOS had no significant association with short-term mortality.
