Abstract
Background: The International Burden of Migraine Study (IBMS) showed chronic migraine (CM) was associated with a higher disease burden than episodic migraine (EM). However, in this study Asians with CM were underrepresented. Objectives: We investigated if CM and EM differed in headache-related disability, health-related quality of life (HRQoL) and health care resource utilization in Taiwan. Methods: This study recruited patients with EM and CM from two headache clinics in Taiwan. Diagnosis was made by physicians based on Silberstein-Lipton criteria. Participants completed a questionnaire including sociodemographics, Migraine Disability Assessment (MIDAS), EuroQol five-dimensions (EQ-5D), Migraine-Specific Quality of Life v2.1 (MSQ), Patient Health Questionnaire-4 (PHQ-4), productivity and health care resource utilization. Results: A total of 331 patients (EM, n = 164 (49.5%); CM, n = 167 (50.5%)) completed the study. CM patients reported a significantly higher MIDAS score, lower generic (EQ-5D visual analogue scale score and EQ-5D index score) and migraine-specific (all three domains of MSQ) HRQoL, higher levels of anxiety and depression (PHQ-4 ≥ 6) and greater health care resource utilization and productivity loss than those with EM. Positive correlations were found between these instruments and levels of anxiety and depression. Conclusion: Compared to EM, CM was significantly associated with higher disability, lower HRQoL and greater health care resource utilization and productivity loss.Keywords
