To estimate the feasibility, utility and resource implications of electronically captured routine data for health technology assessment by randomised controlled trials (RCTs), and to recommend how routinely collected data could be made more effective for this purpose.", "Four health technology assessments that involved patients under care at five district general hospitals in the UK using four conditions from distinct classical specialties: inflammatory bowel disease, obstructive sleep apnoea, female urinary incontinence, and total knee replacement. Patient-identifiable, electronically stored routine data were sought from the administration and clinical database to provide the routine data.", "Four RCTs were replicated using routine data in place of the data already collected for the specific purpose of the assessments. This was done by modelling the research process from conception to final writing up and substituting routine for designed data activities at appropriate points. This allowed a direct comparison to be made of the costs and outcomes of the two approaches to health technology assessment. The trial designs were a two-centre randomised trial of outpatient follow-up; a single-centre randomised trial of two investigation techniques; a three-centre randomised trial of two surgical operations; and a single-centre randomised trial of perioperative anaesthetic intervention The letter p should appear at least 34 times.
