Brief Summary

Aim: To investigate the quality of history taking by physician and computer-based system. Patients: 100 inpatients presenting at the RBK for the first time and treated in the departments of nephrology and cardiology. Methods: The information obtained by the computer based system is compared with the information acquired by conventional history taking. Study endpoint is the comparison of historical data organized according to the elements in a standard medical history on a patient-by-patient basis. Study procedure History taking is performed by physicians 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.

Outcome Measures

Primary Outcomes (1)

• Detection of Medical Problems (by Number of Problems Reported by Computer Assisted History, That Were Not Reported by Physician Taken History)

  Data were extracted from hospital charts by to experienced physicians.; data from the computer histories were extracted by a senior physician, who tabulated comparisons between the 2 sets of records. We used the number of problems reported by Computer Assisted History that were not reported by Physician. Nurses at Robert Bosch Krankenhaus do not take medical histories in regard to allergies or adverse drug reactions. Pharmacists make no entries into charts and have no separate records of drug allergies or history of adverse drug reactions. Data on these issues either are obtained only by physician interview of the patient.

  participants were followed for the duration of hospital stay, an average of 8 days

Study Arms (1)

Inpatients of hospital

OTHER

All patients who were admitted to the departments of nephrology or cardiology in a tertiary hospital in Germany. The intervention was use of an expert system to acquire medical histories by direct interview of patients. 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.

Device: Computer-assisted history; Procedure: physician taken history; Other: Computer-assisted history taking
