Evaluation of breast cancer care under Puerto Rico's Health Care Reform.

Puerto Rico has implemented Health Care Reform legislation that shifted medically indigent and underserved persons from direct care by public sector institutions to managed care arrangements through the private sector. Our aim is to assess how previously underserved women with breast cancer have fared during the first three years of the Reform. Medical claims data were obtained on breast cancer cases in San Juan who were either enrolled in the capitated Reform plan or in a commercial policy offered by the same insurer.
