The impact of prospective pricing on the information system in the health care industry.

The move from a retrospective payment system (value added) to a prospective payment system (diagnostic related) has not only influenced the health care business but also changed their information systems' requirements. The change in requirements can be attributed both to an increase in data processing tasks and also to an increase in the need for information to more effectively manage the organization. A survey was administered to capture the response of health care institutions, in the area of information systems, to the prospective payment system. The survey results indicate that the majority of health care institutions have responded by increasing their information resources, both in terms of hardware and software, and have moved to integrate the medical and financial data. In addition, the role of the information system has changed from a cost accounting system to one intended to provide a competitive edge in a highly competitive marketing environment.
