Prehospital factors associated with ICU admission in drowning patients: a retrospective multicenter cohort study in a French coastal region.
Observational study in BMC emergency medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05751655 (Observational Study of Drowning Patient's Emergency Care in Its Pre-hospital Phase.), which is not on this 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.

Abstract
backgroundDespite its prevalence, limited data describe the European prehospital management of drowning victims outside cardiac arrest situations, and clinical decision-making remains heterogeneous across EMS systems. We aimed to describe the clinical characteristics, prehospital management, and outcomes of drowning patients, and to identify prehospital factors associated with intensive care unit (ICU) admission.
methodsWe performed a retrospective multicenter study including all consecutive adult managed by the emergency medical service (EMS) call-center of the Var department (SAMU 83, France) with a “drowning” code between January 2019 and October 2022. Multivariate logistic regression analysis was used to identify prehospital factors associated with ICU admission.
resultsAmong 296 included patients, 232 patients (78.3%) were admitted to hospital, including 130 (43.9%) to the ICU. Thirty-eight patients (12.8%) were discharge alive without admission, and 26 (8.8%) died during prehospital management. During hospital stay, 185/232 (79.7%) required respiratory support, including 51/185 (27.6%) with mechanical ventilation. Independent factors associated with ICU admission were initial impaired consciousness (OR = 4.4; 95%CI [1.3–15.3]; p = 0.02), Szpilman grade ≥ 3 (OR = 29.9; 95%CI [11.0–80.9]; p < 0.001), and immersion duration ≥ 1 min (OR = 9.0; 95%CI [2.5–32.2]; p < 0.001).
conclusionsSeveral prehospital clinical variables were associated with ICU admission in this retrospective cohort. These findings may inform EMS triage decisions, although prospective validation is required.
trial registrationThe study was prospectively registered at Clinicaltrials.gov on 20 February 2023 (NCT05751655).
