Abstract:
This paper describes a system that is used in Maastricht, the Netherlands, to provide general practitioners with feedback about the adequateness of their test requesting behaviour. The system has proven to be effective. Since the screening of test requests and additional patient data is work-intensive a project was started in the framework of the AIM programme OPENLABS to design a computer-based feedback system. In this system the general practitioner sends test requests to the laboratory decision support system by means of electronic data interchange (EDI). The authors were involved in the development of the EDI messages, which are now accepted standards in the Netherlands. The requests are stored in a database that is part of the laboratory decision support system. The other part of the decision support system, an expert system, obtains the request data (including patient data) from the database, screens the requests for adequateness and provides feedback when necessary.

Decision Making: Traditional Method
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null hypothesis and 'fail to...
