Fall InjuryNCT07093658
High vs Low Fall Injuries in Asia: 7-Year Multicenter Study
An observational study of Fall Injury and Trauma, run by Mackay Memorial Hospital.
Trial summary
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. Read more about this study

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.

About this study
Official title: 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

Questions about this trial
What is this clinical trial studying?
An observational study of Fall Injury and Trauma, run by Mackay Memorial Hospital.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
30-day mortality (time frame: 30-day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07093658, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jul 2025.
