Outcomes of Treatment in Episodic Migraine Patients (N = 282)

2017 – 2018

HIT-6 = Headache Impact Test, PDI = Pain Disability Index, PHQ-9 = Patient Health Questionnaire, PROMIS = Patient Reported Outcome Measurement Information System

In 2017 and 2018, 282 patients with episodic migraine and a follow-up visit were reviewed. The median interval between initial appointment and follow-up was 185 days (range, 141–585). Of the 72 patients who reported HIT-6 scores > 50 at initial evaluation, 29% reported improvement at their second visit.¹ Of the 101 patients who reported initial PDI scores ≥ 20, 34% reported improvement at their second visit.² Of the 81 patients who reported initial PROMIS pain at or above the median score of 6, 100% improved or remained stable. Of the 64 patients who completed the PHQ-9 at 2 visits and reported initial depressive symptoms ≥ 10 points, 33% reported improvement depressive symptoms on follow-up. Overall, approximately 80% of patients reported improved or stable symptoms for all 4 reported measurements.
