JTS is a performance improvement (PI) organization which employs a systematic approach to determine the acute and long-term outcomes of all casualties, the quality of care, improvements in prevention and treatment and logistical implications. The JTS supports U.S. military PI initiatives by identifying, tracking, and making recommendations on PI measures to ensure the appropriate evaluation and treatment of injured Service members across the continuum of care and improve patient transition between phases of care.

The JTS PI Branch coordinates all PI activities across the spectrum of DoD trauma care and resolves trauma system patient care issues. JTS PI work relies on data collected in the DoD Trauma Registry. The data enables JTS to conduct gap analyses for medical capabilities to direct ongoing and future combat casualty care research, trauma skills training, and direct combat casualty care.

OVH utilizes encounter and summary statistics collected from the GTP, ADVISOR call center, OVHRs, and OVHEs to monitor the “health” of the system. Metrics tracked from these sources include:

- Number of Routine, Urgent, and Emergent TCs
- Location origin by Combatant Command
- Number of missed calls and failed connections
- Time from call to connection with RE (urgent/emergent calls) or time to receive recommendation form RE (routine)
- Quality of LC consultations (quality of presentation, appropriateness of questions, ability to provide appropriate recommendations)
- Quality of RE consultations (quality of the interaction, quality of the recommendations, and ability to implement recommendations
- Casualty outcomes when available
- Evacuations avoided or downgraded
- % of OVHR/OVHE completion
