Summary
Most physicians had managed care contracts by 1993. Savings attributed to managed care often stem from healthier enrollees, with minimal outcome differences compared to fee-for-service care.
Area of Science:
- Health Services Research
- Healthcare Economics
Background:
- Managed care contracts were prevalent among physicians by 1993.
- Managed care organizations (MCOs) claim significant cost savings.
- Previous research suggests healthier populations enroll in managed care.
Purpose of the Study:
- To evaluate the claimed savings of managed care.
- To determine the impact of patient selection on managed care savings.
- To compare health outcomes between managed care and fee-for-service models.
Main Methods:
- Analysis of physician contracts and enrollment data.
- Review of existing studies on managed care savings.
- Comparative analysis of health outcomes.
Main Results:
- A majority of studies indicate that managed care savings are partly due to enrolling healthier individuals.
- Differences in health outcomes between managed care and fee-for-service are generally small.
- No significant variations in patient outcomes were observed.
Conclusions:
- Managed care savings may be influenced by healthier patient populations rather than solely by care management.
- The overall impact of managed care on patient outcomes is comparable to traditional fee-for-service models.
- Further research is needed to fully understand the nuances of managed care effectiveness.
