AbstractAn indicator can be defined as a measurable element of care that gives an impression of the quality of care. It can be used for screening on potential quality problems, for monitoring of well-defined processes and for a check after the introduction of quality improvement activities. Although the notion of an indicator appears to be an attractive concept in quality management, some questions have to be answered before a specific indicator can be used. The first question regards the validity of the indicator: to what extent does the indicator reflect the quality of the care? Next is the question of registration: can the indicator be measured in a valid and reliable way? The third question is whether appropriate activities will be initiated after the indicator has given a signal. Postoperative wound infections appears to be a valid outcome indicator because of the relationship between process of care (infection prevention policy) and outcome of care (the number of infections). The weak point lies in the reliability of the registration of wound infections.
