Fall Injury Mortality Prediction
An observational study of Trauma Injury and Mortality Prediction, run by Mackay Memorial Hospital.
Trial summary
This retrospective, multicenter, registry-based cohort study used data from the Pan-Asian Trauma Outcomes Study registry between January 2016 and December 2024. Adult patients with fall-related trauma were included if they had available data on age, sex, emergency department vital signs, and 30-day mortality. Read more about this study

About this study
Official title: Development of a Mortality Prediction Model for Fall Injury Patients: An Analysis of the PATOS Trauma Registry
This retrospective, multicenter, registry-based cohort study used data from the Pan-Asian Trauma Outcomes Study registry between January 2016 and December 2024. Adult patients with fall-related trauma were included if they had available data on age, sex, emergency department vital signs, and 30-day mortality. The final cohort was randomly divided into derivation and validation cohorts in a 2:1 ratio. Candidate predictors were selected based on clinical relevance, field triage criteria, prior trauma literature, and early availability. Multivariable logistic regression was used to develop the model, and regression coefficients were converted into an integer-based score. Model performance was assessed using discrimination, calibration, Brier score, and threshold-based metrics.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Questions about this trial
What is this clinical trial studying?
An observational study of Trauma Injury and Mortality Prediction, run by Mackay Memorial Hospital.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
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?
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 11 Jun 2026.
