Healthy decision making: a new approach in health promotion using health state utilities.

Empowerment of the individual is the central tenet of health promotion philosophy. Application of health state utility methodology to clinical decisions will facilitate this process. The study reported here used health state utilities to examine the preferences of young adults concerning third molar care. Respondents were asked to indicate the strength of their preferences for various outcomes consequent to removing, or not removing these teeth by using standardised visual analogue scales. The results demonstrated that health state utilities for most complications of surgery were lower than, and therefore reduced health more than, those associated with the complications of leaving teeth in place. Therefore dental surgeons should be more circumspect about surgical intervention: this group of potential patients believed that the 'cure' is often worse than the 'disease'. This study illustrates the use of health state utilities, a methodology which allows patients' perspectives to be incorporated into the planning of rational health care.
