Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | No Mobile Phone-administered Triage Tool | For each hospital site: Baseline data will be collected for six months.~\*\*This extended beyond 6 months due to the COVID pandemic\*\*\* | 837 | 1,491 | OG000 |
| Group 2 | Mobile Phone-administered Triage Tool | For each hospital site: After the first six months of baseline data collection, the mobile phone-administered triage tool (or Mobile Phone-based Triage Tool) will be implemented for a year.~\*\*This extended beyond 1 year due to the COVID pandemic\*\*\*~Mobile Phone-based Triage Tool: The proposed intervention is a mobile phone-administered survey. Participants that have been admitted to participating hospitals for treatment of injury will be contacted by mobile phone approximately two weeks after discharge. A seven-question survey will be administered over the phone to each participant. Cross-validation with a separately administered in-person physical exam will be performed to assess the survey tool's prediction of who needs further care for treatment of their injury. | 1,514 | 2,499 | OG001 |
