To investigate the quality of history taking with or without an knowledge based interview system.


400 inpatients presenting at the RBK for the first time and treated in the departments of nephrology and department of hematology/oncology.


The information obtained either by an knowledge based system or by conventional history taking is compared by the patient, by the physician and by independent reviewers. Study endpoint is the percentage of histories missing clinically significant information.

Study procedure After informed consent of the patients the procedure of history taking is performed by the physician according to the guidelines of the RBK. Within 2 days thereafter the patient is interviewed with help of the CLEOS system with the support of a study nurse. The physician will be informed about the results immediately after completion of the questionnaire.

Both the patient and the treating physician will rate the comparative quality of the two histories by means of a questionnaire. In addition, the relevance of the differences of the information obtained by the two systems is rated by an independent reviewer.

Study Start Date: August 2005
Estimated Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: Computer-assisted history
    Methods Description of the software program - The program tested in this study consisted of a data acquisition [history-taking] component and a data analysis component. The data acquisition component was constructed on the basis of established principles of pathophysiology. Medical knowledge was formalized as software algorithms that were machine-readable by representing the knowledge as branched chain decision trees.
