Trial Outcomes & Findings for Improving the Quality of Patient Care by Using a Clinical Expert System. (NCT NCT00430755)
NCT ID: NCT00430755
Last Updated: 2015-12-18
Results Overview
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.

Participant Flow
Patients who were interviewed had been admitted emergently. Patient charts were not consulted prior to any interview; and the study nurse, who picked patients randomly for interview, had no knowledge of these patients before an interview and carried on no discussions with floor staff about a patient's clinical state.
Acquisition of clinical data in the history-taking program is based on the principles of pathophysiology formalized as software algorithms representing medical knowledge as branched chain decision trees.
