Doctors in German hospitals are critical of their working conditions. They complain about long working hours, inadequate remuneration for their work, poor training and development opportunities, and increasing time spent on administrative tasks. As these points of criticism are largely based on subjective perception, in the present study we documented in detail the workflows of physicians in a major regional hospital, determined the time taken for the workflows, and performed a statistical evaluation of the data. Nine doctors from the specialties of internal medicine, surgery, and anesthesia/intensive care medicine were observed during their shifts for a total period of 216 hours at an urban hospital in Germany. All of the tasks performed by the doctors were recorded in an observation protocol. The time spent daily on documentation by doctors of all specialties was on average 93.1 ± 23.4 minutes, accounting for 19.4 % of a doctor's working hours. The specialists who spent the longest period of time on documentation were internists (120.2 ± 15.0 minutes; 25 %). During an eight-hour working day, computers were used on average for 123.5 ± 44.4 minutes; surgeons spent the shortest period of time on computers (71.5 ± 16.6 minutes). The direct patient-related work time (excluding the time spent on operations) was considerably lower (33.8 + 22.7 minutes; 7 %) than thetime spent daily on documentation, increased to 80.7 ± 62.9 minutes when the time expended on actual surgical tasks was taken into account, and was then similar to the time spent on documentation (93.1 minutes). This pilot study was the first to determine, in real time, the work processes of doctors from different specialties at a German hospital. We noted a disparity between administrative and patient-related tasks in the in-patient setting. Legal and economic requirements exert a negative impact on medical care. We need to develop strategies for effective utilization of medical resources and for ensuring a high standard of medical care.
