- Limitations and caveats
Early in the COVID pandemic due to restrictions in Cameroon and to ensure safety of participants, changes were made such as pausing intervention phase where patients were asked to return to the hospital for a physician exam to cross-validate the telephone triage tool and reverting to baseline. The step-wedge design was also scrapped as this was disrupted by the pause. Low recruitment numbers in COVID also accounted for the intervention phase to be extended beyond the pre-specified timeline.

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Proportion of Successful Contacts | 2 weeks after enrollment | The number of successful contacts will be divided by the total number of contacts. A "successful" contact is when an enrolled patient answered the phone, and consented to the research assistant administering the questionnaire(s) planned for that phone call. |
| Primary | Median Number of Attempts Required to Achieve a Successful Contact | 2 weeks after enrollment | This is the median number of call attempts made until a research assistant is able to successfully administer the questionnaire(s) planned for that phone call. |
| Primary | Median Cost Associated With Personnel Time | At the end of the study (2 weeks after the 2-year intervention phase (extended due to COVID)) | This measure is median monthly costs incurred to pay the research assistant for the time s/he spends making the required phone calls per patient. |
| Primary | Median Cost Associated With Telephone Time | At the end of the study (2 weeks after the 2-year intervention phase (extended due to COVID)) | This measure is the median costs incurred to make phone calls per patient in each study phase. |
| Primary | Telephone Triage Tool Administration Time | After administration of the telephone triage tool (i.e. about 2 weeks after enrollment) | This measure will be calculated based on how much time it takes to administer the telephone triage tool. |
| Primary | Physician Assessment of Whether a Patient Would Benefit From Further Services | Immediately after the physician administers the physical exam (i.e. about 3 weeks after enrollment) | This is a binary measure. After a physician examines a participant, s/he will determine whether s/he thinks the participant would benefit from further services (including additional follow-up care, and/or diagnostic or therapeutic interventions). |
| Primary | Physician Assessment of Whether a Patient Was at Moderate to High Risk for a Poor Outcome (HR) Without Additional Intervention | Immediately after the physician administers the physical exam (i.e. about 3 weeks after enrollment) | After a physician examines a participant, s/he will determine whether s/he thinks the participant is at low, moderate or high risk for a poor outcome (HR) without additional intervention using subjective clinical assessment. |
| Primary | Triage Risk Score (TRS) | At the end of intervention phase (about 1 year after enrollment). | To develop a sensitive model capable of risk stratifying triaged patients for high risk (HR), all candidate questions from the telephone triage tool found to associate with HR on univariate regression were weighted by their predictive coefficient and added to generate a triage risk score (TRS) ranging from a minimum score of 0 (lowest risk) to a maximum possible score of 43.9 (highest risk). Triage Risk Score (TRS) less than or equal to 1.3 (1st quartile) was designated as low risk, TRS 1.4 to 4.0 (2nd \& 3rd quartile) as moderate risk, and TRS greater than or equal to 4.1 (fourth quartile) as high risk. |
| Primary | Acceptability Score of Mobile Phones as a Follow-up Tool | 2 weeks after enrollment | This is a numerical measure that represents the sum of the positive responses that participants give to each question that assesses the acceptability of mobile phones as a follow-up tool. The scale for the acceptability score of mobile phones as a follow-up tool ranges from 0 to 6, where 0 means the participant's responses indicate the participant believes mobile phones are definitely not an acceptable follow-up tool and 6 means the participant's responses indicate the participant believes mobile phones are definitely an acceptable follow-up tool. |
| Primary | Proportion of Injured Patients Who Seek Clinical Follow-up Evaluation | After the 2week post-discharge phonecall. | This will be calculated as follows: The denominator will be the number of discharged trauma patients enrolled in the study. The numerator will be the number of discharged trauma patients enrolled in the study who seek any clinical follow-up evaluation at the 2 weeks post-discharge phonecall. |
