    (Wolters Kluwer, 2022) Seng, Elizabeth K.; Fenton, Brenda T.; Wang, Kaicheng; Lipton, Richard B.; Ney, John; Damush, Teresa; Grinberg, Amy S.; Skanderson, Melissa; Sico, Jason J.; Medicine, School of Medicine
    Objective: To describe the relative frequency, demographics, comorbidities, and healthcare utilization of veterans who receive migraine care at the Veteran's Health Administration (VHA) and to evaluate differences by gender. Methods: This study extracted data from VHA administrative sources. Veterans diagnosed with migraine by a healthcare provider between fiscal year 2008-2019 were included. Demographics and military exposures were extracted at cohort entry. Comorbidities were extracted within 18 months of the first migraine diagnosis. Health care utilization and headache comorbidities were extracted across the study period. Differences between men and women were evaluated using chi-square tests and student t-tests. Results: More than half a million (n = 567,121) veterans were diagnosed with migraine during the 12-year study period, accounting for 5.3% of the 10.8 million veterans served in the VHA; in the most recent year of the study period (2019), the annual incidence and one-year period prevalence of medically diagnosed migraine was 2.7% and 13.0% for women, and 0.7% and 2.5% for men. In the total cohort diagnosed with migraine, 27.8% were women and 72.2% men. Among those with diagnosed migraine, a higher proportion of men vs. women also had a TBI diagnosis (3.9% vs. 1.1%; p < 0.001). A higher proportion of women vs. men reported military sexual trauma (35.5% vs. 3.5%; p < 0.001). Participants with diagnosed migraine had an average of 1.44 (SD 1.73) annual encounters for headache. Primary care was the most common headache care setting (88.1%); almost one-fifth of veterans with diagnosed migraine sought care in the ED at least once during the study period. Common comorbidities were overweight/obesity (80.3%), non-headache pain disorders (61.7%), and mental health disorders (48.8%). Conclusions: Migraine is commonly treated in the VHA setting, but likely under ascertained. Most people treated for migraine in the VHA are men. Pain comorbidities and psychiatric disorders are common. Future research should identify methods to improve diagnosis and treatment and to reduce use of the emergency department.

    Telehealth perceptions and utilization for the delivery of headache care before and during the COVID-19 pandemic: A mixed-methods study
    (Wiley, 2022) Grinberg, Amy S.; Fenton, Brenda T.; Wang, Kaicheng; Lindsey, Hayley; Goldman, Roberta E.; Baird, Sean; Riley, Samantha; Burrone, Laura; Seng, Elizabeth K.; Damush, Teresa M.; Sico, Jason J.; Medicine, School of Medicine
    Objective: The objective of this study was to evaluate the utilization of telehealth for headache services within the Veterans Health Administration's facilities housing a Headache Centers of Excellence and multiple stakeholder's perspectives to inform future telehealth delivery. Background: Telehealth delivery of headache treatment may enhance patient access to headache care, yet little is known about the utilization or patient and provider perceptions of telehealth for veterans with headache. Methods: This mixed-methods study analyzed multiple data sources: (1) administrative data, which included 58,798 patients with medically diagnosed headache disorders, documented in at least one outpatient visit, from August 2019 through September 2020 from the 12 Veterans Health Administration's facilities with a Headache Center of Excellence and (2) qualitative semistructured interviews with 20 patients and 43 providers 6 months before the coronavirus disease 2019 (COVID-19) pandemic, and 10 patients and 20 providers 6 months during the beginning of the pandemic. Results: During the pandemic, in-person visits declined from 12,794 to 6099 (52.0%), whereas video (incidence rate ratio [IRR] = 2.05, 95% confidence interval [CI] = 1.66, 2.52), and telephone visits (IRR = 15.2, 95% CI = 10.7, 21.6) significantly increased. Utilization differed based on patient age, race/ethnicity, and rurality. Patients and providers perceived value in using telehealth, yet had limited experience with this modality pre-pandemic. Providers preferred in-person appointments for initial encounters and telehealth for follow-up visits. Providers and patients identified benefits and challenges of telehealth delivery, often relying on multiple delivery methods for telehealth to enhance patient engagement. Conclusions: The uptake of telehealth delivery of headache-related care rapidly expanded in response to the pandemic. Patients and providers were amenable to utilizing telehealth, yet also experienced technological barriers. To encourage equitable access to telehealth and direct resources to those in need, it is crucial to understand patient preferences regarding in-person versus telehealth visits and identify patient groups who face barriers to access.
