AbstractIn an open three-center pilot study, 17 patients suffering from chronic persistent pain syndrome, due to osteoarthritis of the hip and knee or spondylarthrosis, were treated orally with 1800-2400 mg Ibuprofen per day for 3 weeks. The chronic pain syndrome and joint status were assessed by the physician at the beginning, and after 7, 14 and 21 days. Self-assessments were made by the patients six times daily during the full study period by means of battery-driven electronic diaries (E.D.). The data entered by the patients were stored in the E.D. and after online transfer, processed and evaluated in a PC using appropriate software programs. E.D. were returned by 16 of 17 patients for evaluation. The technical functioning of the instrument was perfect; its use was accepted by patients and physicians. The closely-meshed real-time recording of pain course and other subjective data, such as adverse events or medication, etc., enables the physician to calculate more exactly and reliably improvement rates, as well as to carry out prognostic trend analyses and individual benefit-risk-ratio estimates. By comparing different kinds of data, each entered at the same time, plausibility checks are possible. The procedure presented here is considered to be a new valuable tool for reviewing subjective data from clinical drug trials.
