title: [Computer-supported patient history: a workplace analysis].
abstract: Since 1991, an extensive computer network has been developed and implemented at the Cantonal Hospital of Lucerne. The medical applications include computer aided management of patient charts, medical correspondence, and compilation of diagnosis statistics according to the ICD-9 code. In 1992, the system was introduced as a pilot project in the departments of pediatrics and pediatric surgery of the Lucerne Children's Hospital. This new system has been prospectively evaluated using a workplace analysis. The time taken to complete patient charts and surgical reports was recorded for 14 days before and after the introduction of the computerized system. This analysis was performed for both physicians and secretarial staff. The time delay between the discharge of the patient and the mailing of the discharge letter to the family doctor was also recorded. By conventional means, the average time for the physician to generate a patient chart (26 minutes, n = 119) was slightly lower than the time needed with the computer system (28 minutes, n = 177). However, for a discharge letter, the time needed by the physician was reduced by one third with the computer system and by more than one half for the secretarial staff (32 and 66 minutes conventionally; 22 and 24 minutes respectively with the computer system; p < 0.0001). The time required for the generation of surgical reports was reduced from 17 to 13 minutes per patient and the processing time by secretaries from 37 to 14 minutes. The time delay between the discharge of the patient and the mailing of the discharge letter was reduced by 50% from 7.6 to 3.9 days.(ABSTRACT TRUNCATED AT 250 WORDS)
