The study is part of a comprehensive project, in which also physicians participated in the validation of such computerized medical records. In total 99 patients, visiting the outpatient clinic of Internal Medicine for the first time, took part in this in-depth study, in which they could express themselves via an interactive and modified terminal and keyboard. The questionnaire that was used in the system contains 28 different screens. Patient complaints are entered together with data on frequency, severity, onset, and duration. The patient may indicate his physical complaints on a stylized picture of the human body. Of the 99 patients, 67 answered the full questionnaire, and another 16 the main part. On the average, 66 min were needed. Younger patients do complete the history in a significantly shorter time than older patients, resulting in relatively more completed histories for the younger group. Quick patients answered on the average 3.5 questions per minute, the slow patients only 2.5. This was strongly correlated with patient familiarization, that has also been investigated: patients who had a quick familiarization were able to finish within 50 min. Patients who needed no help at all in using the system had even answering rates of 3.9/min. | lld:pubmed |
