title: Balancing patient preferences and clinical needs: community versus hospital based care for patients with suspected DVT.
abstract: OBJECTIVE
  To establish patients' preferences and willingness to pay (WTP) for different service models for suspected deep vein thrombosis (DVT).
  
  
  METHODS
  We analysed patient responses to a discrete choice experiment (DCE) questionnaire which had been targeted at patients in Leicester, UK. The questionnaire elicited preferences/WTP for attributes of DVT provision including speed of diagnosis; access; continuity of care; and minimizing hospital visits. Additionally we evaluated trade-offs between clinical and service attributes. We analysed responses from 256 patients with suspected DVT (65% response rate).
  
  
  RESULTS
  Respondents are WTP pound 4.82 per extra hour of dedicated DVT service provision; pound 17.12 per hospital visit avoided; pound 115.73 per day's reduction in diagnostic wait; and pound 179.32 for 'much' not 'some' continuity, or pound 56.88 for 'some' not 'lack' of continuity in nursing.
  
  
  CONCLUSIONS
  Research evaluating different DVT service models usually reports on clinical efficacy in centres of excellence. Results show prompt diagnosis is valued by patients and may improve efficacy by reducing unnecessary anticoagulation. However, patients value 'process' measures such as continuity of care also. To ensure optimal provision, clinical benefit measurement ought to be augmented with information on patients' preferences.
