High vs Low Fall Injuries in Asia: 7-Year Multicenter Study

July 23, 2025 updated by: Tse-Hao Chen, Mackay Memorial Hospital

Epidemiology and Outcome of High Versus Low Fall Injury in Asia Countries: A 7-year Multicenter Cohort Study

This multicenter study revealed a declining overall incidence of fall-related injuries, accompanied by a rising proportion of high falls, predominantly among non-elderly males. Mortality risk increased significantly at fall heights of 3 and 6 meters, supporting current field triage thresholds. Across both high and low falls, lower SpO₂ and GCS were key predictors of 30-day mortality, with head injury being an additional risk factor in low fall cases

Study Population

This study included adult patients (aged ≥18 years) who were transported by emergency medical services (EMS) between January 2016 and December 2022. Patients were excluded if they had missing data on age, sex, injury mechanism, systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), oxygen saturation (SpO₂), Glasgow Coma Scale (GCS), Abbreviated Injury Scale (AIS) for each body region, Injury Severity Score (ISS), Revised Trauma Score (RTS), or fall height. In addition, patients with missing records of 30-day mortality were excluded from the mortality cohort analysis.
