An electronic patient-reported outcome (ePRO) is a patient-reported outcome that is collected by electronic methods. ePRO methods are most commonly used in clinical trials, but they are also used elsewhere in health care. As a function of the regulatory process, a majority of ePRO questionnaires undergo the linguistic validation process. ==Methods== The two main methods currently used for ePRO are computers/Smartphones and telephone systems ''Computers'' are most often touch-screen devices, ranging from small hand-helds such as the Palm Pilot, through tablet PCs. The smaller devices are often used as electronic diaries, designed to be used for symptom reporting on a daily basis. Larger devices are generally used in a clinic setting. Computers generally run dedicated ePRO applications - the use of the web for ePRO is not yet widespread. Typically a single question at a time is presented on the screen, with a set of possible response options. The user taps on the appropriate response with finger or stylus, then moves on to the next questions. ''Telephones'' normally use an interactive voice response system (IVR). The user calls into a dedicated phone line, and hears a spoken script which details the question, and the possible responses. Each response option is given a number, and the user presses the corresponding number key on the phone keypad to record the choice. IVR systems are more often used for diaries, with the patient phoning in e.g. from home, but they can be used in a clinic setting. There are also a number of custom devices designed specifically for use as ePRO data collection devices. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Electronic patient-reported outcome」の詳細全文を読む スポンサード リンク
