Concurrent clinical review: using microcomputer-based DRG-software.

Since the introduction of the Prospective Payment System based on Diagnosis Related Groups (DRGs) in the U.S.A., important information technologies are arising. We discuss how Professional Review Organizations, (PROS) are forcing a better control of appropriateness and quality of medical care. Hospitals should have the internal capabilities to perform, at least, the same reviews as performed by the PROs. Concurrent Clinical Review Systems based on DRGs are a special type of information technology that take place during and even before patient hospitalization, therefore allowing an 'on line' monitoring information. Low-cost microcomputers are playing a major role in the popularization of this technology. 'Clinical Review System' is a microcomputer-based software that renders easy and feasible and otherwise complex task. An effort should be made in order to adapt the philosophy underlying this or other similar software to the European needs.
