Health maintenance organizations (HMOs) have evolved, requiring new ways to classify them. This study proposes two typologies based on contractual arrangements and incentives to better understand the managed care industry.

Area of Science:

  • Health Services Research
  • Healthcare Management
  • Organizational Studies

Background:

  • Health maintenance organizations (HMOs) have undergone significant evolution.
  • Existing classifications inadequately capture structural and incentive changes.
  • Physician participation is a key factor influenced by these changes.

Purpose of the Study:

  • To develop novel typologies for classifying HMOs.
  • To explicitly address key features of HMO evolution and physician incentives.
  • To provide a framework for understanding the dynamic managed care industry.

Main Methods:

  • Examining two- or three-tiered contractual arrangements.
  • Analyzing physicians' payment methods.
  • Investigating clientele served and risk-pooling mechanisms.
