  1. Managed care and capitation in California : how do physicians at financial risk control their own utilization ?

    Article - En anglais


    To describe the structure and range of utilization management methods initiated by physicians in response to capitation..


    Cross-sectional questionnaire..


    A large network-model health maintenance organization (133 contracting physician groups) in California..


    94 (71%) physician groups caring for 2.9 million capitated patients..


    Self-reported use of five major utilization management methods..


    All physician groups reported using gate-keeping and preauthorization for certain referrals or tests.

    Most also used profiling of utilization patterns (79%), guidelines (70%), and managed care education (69%). Most physician groups asked gatekeepers to submit preauthorization requests for specialty referrals and restricted patient self-referral.

    For example, 60% of groups required preauthorization for an intemal medicine subspecialty referral, and 7% allowed patient self-referral.

    Most groups also asked gatekeepers to obtain preauthorization for many tests (for example, 95% for magnetic resonance imaging and 53% for pulmonary function tests).


    Physicians are responding to capitation by using utilization management techniques, some at early stages of development, that were previously used only by insurers.

    This physician-initiated management approach represents a fundamental transformation in the practice of medicine.
