Background: Despite the expanding therapeutic armamentarium, many people with episodic migraine (EM) have unmet acute treatment needs.
Objective: To determine the relative frequency of prespecified types of "unmet treatment needs" in persons with EM in a US population-based sample.
Methods: Eligible participants completed the 2009 American Migraine Prevalence and Prevention Study survey and met International Classification of Headache Disorders-2nd edition (ICHD-2) criteria for migraine with an average headache day frequency of <15 days per month (EM). We identified 5 domains of unmet treatment needs: (1) dissatisfaction with current acute treatment using 3 summary items from the Patient Perception of Migraine Questionnaire-revised edition (PPMQ-R); (2) moderate or severe headache-related disability defined by a Migraine Disability Assessment Scale score of ≥11; (3) excessive use of opioids or barbiturates defined as use on ≥4 days/month or by meeting Diagnostic and Statistical Manual for Mental Disorders-4th edition criteria for dependence; (4) recurrent use of the emergency department or urgent care clinic for headache defined by ≥2 visits in the preceding year for headache; and (5) history of cardiovascular events indicating a possible contraindication to triptan use. For each respondent, we identified their unmet treatment needs in each category and classified them as having no unmet needs or 1 or more unmet needs.
Results: Of 5591 respondents with EM, 2274 (40.7%) had 1 or more unmet needs; 1467 (26.2%) had exactly 1 unmet need, and 807 (14.4%) had 2 or more unmet needs. Among those with at least 1 unmet need, 1069 (47.0%) had moderate or severe headache-related disability, 851 (37.4%) were dissatisfied with their acute treatment regimen, 728 (32.0%) had excessive opioid or barbiturate use and/or probable dependence, 595 (26.2%) had a history of cardiovascular events, and 129 (5.7%) reported ≥2 visits in the preceding year to the emergency department/urgent care clinic for headache. Persons with more headache days, depression, or generalized anxiety were more likely to have unmet treatment needs.
Conclusion: In a population sample of individuals with EM, more than 40% have at least 1 unmet need in the area of acute treatment. The leading reasons for unmet needs, which include headache-related disability and dissatisfaction with current acute treatment, suggest opportunities for improving outcomes for persons with EM.
