Physician's working diagnosis compared to the Euricterus Real Life Data Diagnostic Tool Trial in three jaundice databases: Euricterus Dutch, independent prospective and independent retrospective.

Background/aims: In the European Union Euricterus Project on (sub)Icterus proforma, the history and physical examination items were to be used for the physician's working diagnosis (PWD) and 'among others, for the development of the real life data electronic diagnostic tool, Trial. Trial delivers diagnosis probabilities based on Bayes' Theorem (B), completed by Trial Algorithm (TA). We wanted to compare the diagnostic accuracies (PWD and Trial probabilities as a percentage of the final diagnosis (FD) in a patient population) in 3 Dutch databases.

The information value of clinical data.

Decisional aids are dependent on the accuracy, comprehensiveness and decisional value of the observations in the database and the test subject. Diagnostic data stem from the observations of the patient, the doctor and third party tests. An information-utility index was used to compare the diagnostic contribution of these sources.
