About this study
Official title: MOTORCYCLE THORACIC TRAUMA SEVERITY SCORE DEVELOPMENT AND VALIDATION OF A NOVEL PREDICTIVE TOOL FOR MORTALITY AND PULMONARY COMPLICATIONS
This study aimed to test the hypothesis that a practical, bedside-applicable tool could be developed to help identify patients at high risk of mortality following motorcycle accidents more quickly and facilitate treatment by enabling faster clinical decision-making.
Read the detailed description
Injuries resulting from motorcycle accidents are one of the leading causes of death worldwide, and rates are increasing. This increase is attributed to the disproportionate vulnerability of riders at the moment of impact, inadequate protective barriers during collisions, motorcycles' ability to reach high speeds and biomechanical exposure. The thoracic cage is the anatomical region most commonly affected in motorcycle accident-related injuries. This study aimed to test the hypothesis that a practical, bedside-applicable tool could be developed to help identify patients at high risk of mortality following motorcycle accidents more quickly and facilitate treatment by enabling faster clinical decision-making.

The record says: finished, as of the sponsor's last update on 16 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
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?
In-hospital mortality (time frame: 30 days after ICU admission). 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 NCT07582263, 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 16 Jun 2026.
