Abstract
Background
The burden of migraine goes beyond the pain and associated symptoms. We aimed to describe the impact of migraine in healthcare resource utilization (HCRU), work productivity, and mood disorders, as well as its economic cost.
Methods
Case–control study nested in a cross-sectional analysis of patient-reported data collected between 30/12/2019 and 20/04/2020 as part of the National Health and Wellness Survey, from respondents located in Spain. Adults (≥ 18 years old) who reported a physician diagnosis of migraine and ≥ 1 monthly headache days (MHD) in the previous 30 days were included. HCRU, health-related quality-of-life, depression scores, work and activity impairment, and the associated direct and indirect costs were assessed for four cohorts of migraine patients, according to the frequency of headache (MHD: 1–3, 4–7, 8–14, ≥ 15) and compared to a no-migraine control, matched to migraine cases by a propensity score based on demographic and clinical variables.
Results
The survey was completed by 595 people with active migraine, of whom 461 (77.4%) experienced < 8 MHDs and 134 (22.6%) ≥ 8 MHDs, and 1,190 non-migraine matched controls. Migraine patients presented worse mental and physical health functioning (SF-12 MCS: 41.9 vs. 44.7, p < 0.001; SF-12 PCS: 48.6 vs. 51.5, p < 0.001), worse self-reported health (EQ-5D VAS: 65.8 vs. 73.5, p < 0.001), more severe depression (PHQ-9: 8.9 vs. 6.1, p < 0.001), and higher overall work impairment (WPAI: 41.4 vs. 25.5, p < 0.001). People with migraine had higher HCRU, twice higher hospitalization rates (17.0% vs. 8.3%, p < 0.001) and 1.6 higher emergency room (ER) visit rates (51.4% vs. 31.2%, p < 0.001). Having migraine translated into higher annual costs with HCRU (€894 vs. €530) and productivity losses (€8,000 vs. €4,780) per person. Respondents with more MHDs presented worse outcomes and higher costs but suffering from 1–3 MHD also increased costs by 51.3%.
Conclusions
Having migraine not only causes a massive impact on patients’ quality of life and ability to work, but it also generates considerable economic costs for society. In Spain, having migraine was associated to 1.7 higher costs per patient. The clinical and economic burden increases with the frequency of headaches but is higher than controls even in patients suffering from 1–3 MHD.
