title: Migraine frequency and health utilities: findings from a multisite survey.
abstract: OBJECTIVE
  Assess the relationship between migraine frequency and health utility.
  
  
  METHODS
  Patients aged >/=18 years diagnosed with episodic migraine were enrolled at three US sites representing varied models of health-care delivery. All subjects completed a questionnaire that included demographic and clinical information, a migraine-specific disability questionnaire, and the Health Utilities Index Mark 3 (HUI3). The HUI3 is a generic health status and health-related quality-of-life measure. HUI3 health status data are translated into utility scores anchored by 0 (dead) and 1 (perfect health).
  
  
  RESULTS
  The study enrolled 150 patients. The mean age was 44 years and 87% were female. Mean (+/-SD) monthly migraine frequency was 4.4 +/- 3.6, with 34% reporting </=2 migraines per month and 20% reporting >6 migraines per month. The mean (+/-SD) HUI3 score was 0.62 +/- 0.26. After controlling for study center, demographics, comorbidities, migraine characteristics, and level of migraine disruptiveness, migraine frequency was found to be significantly (P < 0.05) and negatively associated with HUI3 scores. Subjects with >6 migraines per month had an adjusted mean HUI3 score of 0.41; the corresponding mean for those reporting </=2 migraines per month was 0.67. Migraine frequency was positively associated with higher levels of disability for the emotion, cognition, and pain components of the HUI3.
  
  
  CONCLUSIONS
  Among this group of care-seeking patients, migraineurs' health utilities were inversely related to headache frequency. Although these data may not be generalizable to the entire migraine population, they may be useful in assessing the comparative cost-effectiveness of preventive migraine therapies.
