Hypothesis
Is participation intensity and prior indication of uncontrolled diabetes associated with health care use and costs for participants in TRICARE's diabetes management program?
Conclusion
Greater intensity of participation in TRICARE's diabetes management program was associated with lower medical costs and improved receipt of recommended testing.
Supporting Evidence
- Active participants had larger reductions in inpatient days and emergency department visits.
- Participants with uncontrolled diabetes realized greater program benefits.
- Per-person total annual medical savings averaged $783 for program participants.
Takeaway
This study shows that people with diabetes who participate more actively in a management program save more money on medical costs and get better health check-ups.
Methodology
A quasi-experimental approach was used to assess program impact, comparing outcomes of participants with a historical control group.
Potential Biases
Selection bias may occur as highly motivated patients are more likely to participate actively.
Limitations
The opt-out nature of the program and the lack of a concurrent control group may introduce selection bias.
Participant Demographics
Participants were aged 18 to 64, with a mix of active-duty service members, family members, and retirees.
