Physician responses to Medicare payment reform: an update on access to care.

This paper updates previous research on physician-based measures of access to care for Medicare beneficiaries following the implementation of Medicare payment reform in 1992. Using data collected in spring 1993, the results show that the majority of physician-based access indicators did not change significantly from 1992 levels. Those indicators that did change generally offset reductions in access identified immediately after the implementation of Medicare physician payment reform.
