Theoretically, evaluation should help decision-makers address contemporary health system challenges. Paradoxically, the use of evaluation results by decision-makers remains poor, despite rapid development in the evaluation field. The level of use depends on the evaluator's ability to account for the complexity of health-care systems. The complex nature of an intervention often compels evaluators to adopt unconventional approaches to account for the roles of the players. The evaluation of a complex intervention raises conceptual, methodological, and operational challenges the evaluation has to overcome to increase the level of use of its findings by decision-makers.

We have analyzed the impact of a clinical information system designed to give feedback on profiles of medical practice in two hospitals. The system was planned to use group influence to induce change among deviant physicians. The information system failed to modify the physician's practice profiles. A large part of this failure is linked to the small variation recorded in utilization patterns among physicians. Medical practice appears to be quite homogeneous in a setting such as a hospital where the clinical behavior of physicians is highly visible to colleagues.
