Summary
Managed care slightly improved depression treatment cost-effectiveness by reducing costs, but did not significantly enhance treatment effectiveness. Further system changes are needed for greater cost-effectiveness.
Area of Science:
- Health Services Research
- Mental Health Economics
- Public Health Policy
Background:
- Managed care introduction in Puerto Rico aimed to alter healthcare delivery.
- Assessing system-level cost-effectiveness is crucial for evaluating healthcare reforms.
Purpose of the Study:
- To evaluate the impact of managed care on the cost-effectiveness of depression treatment.
- To analyze changes in treatment costs and effectiveness at a population level.
Main Methods:
- Study population: Adults (18-69) in low-income Puerto Rican areas.
- Data collection: Three waves (pre- and post-managed care) using random sampling.
- Analysis: Difference-in-difference estimators to assess managed care's impact on depression treatment costs and effectiveness.
Main Results:
- System cost-effectiveness saw a slight improvement post-managed care implementation.
- Treatment costs decreased, but no significant gains in treatment effectiveness were observed.
Conclusions:
- Population-level cost-effectiveness analysis is a valid method for assessing healthcare system changes.
- Achieving a more cost-effective system requires incentives and realignments beyond utilization review and cost reduction.
