A substantial proportion of hospital stay was found to be inappropriate, due to hospital procedures and the inability to refer patients to other care facilities or care providers. Analysis of the causes of IPS provided useful data for improvement actions. Efficient use of hospital resources should be promoted by reducing the delay in interventions and discharge procedures.

Objective-To assess the effects of feedback on the test ordering behaviour of general practitioners.Design-Comparison of requests at two diagnostic centres, and internal comparison between tests which were discussed in feedback and tests which were not.Setting-A diagnostic centre in Maastricht giving feedback and another elsewhere in the Netherlands (laboratory A) not giving feedback.Subjects-All 85 general practitioners in the region of Maastricht, and all general practitioners in the region of laboratory A.Main outcome measures-Numbers of tests requested by general practitioners.Results-Requests at the Maastricht diagnostic centre decreased soon after the onset of feedback whereas there was a persistent increase in requests at laboratory A. Tests that were discussed showed the strongest decrease (maximum 40%), though tests that were not discussed decreased as well (maximum 27%).Conclusions-Feedback on diagnostic requests may exert a strong influence on request behaviour. Four years after the onset of feedback the effects were still noticeable.

Scoring models based on history and physical examination have been developed to discriminate patients with non-organic gastrointestinal disease from those who have organic disease. The application of these models may lead to more efficient diagnosis and prevent somatization. Although the models have high diagnostic accuracy in the population in which they have been developed, their value in other populations has not been established. In this study previously developed models were tested in validation populations defined by the original selection criteria from the studies in which the models were developed and in unselected general practice and outpatient populations. The diagnostic performance of the models are expressed in terms of odds ratio and sensitivity and specificity for the classification of patients as having organic and non-organic disease. The diagnostic performance of all the models were rather low in the validation populations. Relatively few elements of the models had independent diagnostic value. In addition, the correlation between the scoring models, expressed in Cohen's kappa, was extremely low. The diagnostic values of the scoring models were not reproduced in comparable and unselected populations. Therefore, it is concluded that the diagnostic value of such a model has little external validity.

Based on the literature review and our own findings, we conclude that the validity and reliability of the different versions of the AEP are not yet up to standard. Regarding the results of the interventions thus far, we do not encourage further use until additional improvements to both the instrument and the review conditions have been made. Perhaps a more disease-specific modulation and assessments based on computerized medical records could improve its applicability in clinical practice in general.

More years of experience as a general practitioner and a shorter duration of consultations correlated with a better response to advice given in the feedback.
