There is a strong need to provide scientific evidence supporting the effectiveness of specific health care interventions. Guidelines alone are unlikely to persuade physicians to modify their practice styles, unless research evidence having a motivational impact is also provided. Process-outcome parameters provide a solution for linking the process and outcome of health care and incorporate potentially motivating research evidence.
