Implementing Medicaid managed care: the New York City story.

Across the nation, public officials are encouraging or requiring Medicaid beneficiaries to enroll in managed care. In this article, we report on a study of the implementation of Medicaid managed care in New York City. Several findings are clear. First, government officials need to treat health plans as partners rather than adversaries; in New York, the relationship between the state and the plans is far too adversarial. Second, effective managed care requires good management information systems; New York officials are collecting an enormous amount of data but not much useful information. Third, effective implementation of Medicaid managed care is slow going; New York's effort to dramatically accelerate the enrollment process did not work.
