Abstract
OBJECTIVE: To determine utility and willingness to pay (WTP) values for patients undergoing orthognathic treatment in a National Health Service hospital in the United Kingdom and to establish whether WTP values can be used as a measure of strength of preference. PARTICIPANTS: Forty patients who were about to start orthognathic treatment were recruited over a 10-month period between January and October 1998. OUTCOME MEASURES: Utility values were obtained using the standard gamble method and WTP values were determined using a payment card method. The relationship between the two was assessed. RESULTS: The mean utility value was 0.73 and the mean WTP was 6,833 pounds. The correlation between these two measures was -0.46 (P<0.01). CONCLUSIONS: The correlation between the utility and WTP values was in the expected direction thus suggesting that WTP may be used as a measure of strength of preference. Therefore, willingness to pay may be a useful technique to combine with cost utility analysis.
