Managed care plans: characteristics, growth, and premium performance

Area of Science:

• Health Services Research
• Healthcare Management
• Health Economics

Background:

• Managed care plans have transformed significantly over the past decade, moving from a niche market to dominating health plan enrollment.
• The evolution saw newer network-based managed care plans surpass older group and staff model Health Maintenance Organizations (HMOs).
• Employers' desire to control rising healthcare costs drove a rapid shift towards managed care, though unpreparedness existed among employers, enrollees, and providers.

Purpose of the Study:

• To analyze the transformation and evolution of network-based managed care plans.
• To highlight the challenges and learning curves faced by various stakeholders in the healthcare system.
• To underscore the increasing complexity of managed care relationships and the need for refined classification methods.

Main Methods:

• Analysis of enrollment trends in different types of managed care plans from the 1980s to 1993.
• Examination of the factors influencing the shift from indemnity insurance to managed care.
• Review of the evolving contractual relationships within the healthcare system.

Main Results:

• Managed care plans grew from a niche to a majority of enrollees by 1993, with newer network models rapidly gaining popularity.
• Significant "learning curves" were observed for employers, enrollees, intermediaries, and providers adapting to managed care.
• The complexity and variety of managed care plans increased, leading to challenges in classification and performance comparison.

Conclusions:

• The healthcare landscape has been reshaped by the rapid adoption and evolution of managed care plans.
• The shift to managed care involved substantial adaptation challenges for all stakeholders.
• Future research must focus on provider organizations and networks for meaningful performance comparisons due to increasing plan complexity.
