Provider responses to a global budgeting system: The case of drug expenditures in Taiwan hospitals.

In July 2002, a global budgeting system was imposed on hospitals in Taiwan. This system set a fixed budget for all hospitals within a region but included special provisions that sheltered reimbursements for drug expenditures. We study the size and nature of changes in hospital physicians' use of drugs for outpatient care following this budgetary change and find that drug expenditures for outpatient care increased by 11.7%. Our results suggest that physicians began prescribing more expensive drugs, more drugs, and drugs for longer periods but that these different responses did not all occur at the same time. The overall response was strongest in for-profit hospitals, but drug-related decisions changed in all hospital types.
