Article Synopsis
- The study aims to analyze the epidemiology of cluster headaches (CH) using Veterans Health Administration (VHA) Electronic Health Record data, highlighting the challenges of population-level studies due to the low prevalence of CH (~0.1%).
- Utilizing VHA data from 2008 to 2019, the research identifies over 24,000 patients diagnosed with CH, revealing a one-year prevalence of 0.08% to 0.10% for women and 0.10% to 0.18% for men.
- Findings show a higher prevalence of unspecified CH among women, with many patients also experiencing comorbid conditions like migraine, depression, and other pain diagnoses, emphasizing the complexity of CH cases within the
Importance: Open burn pits have commonly been used for waste disposal by the US military but have not been systematically investigated as an independent risk factor for headache disorders.
Objective: To evaluate the association between exposure to open burn pits and incidence of headache and migraine.
Design, Setting, And Participants: This retrospective cohort study used data from the Veterans Health Administration Headache Cohort along with data from the US Department of Defense and the Airborne Hazards and Open Burn Pit (AH&OBP) Registry to assess registry participants with potential exposure to open burn pits in the Veterans Health Administration from April 1, 2014, through October 31, 2022.
Optimal triage biodosimetry would include risk stratification within minutes, and it would provide useful triage despite heterogeneous dosimetry, cytokine therapy, mixed radiation quality, race, and age. For regulatory approval, the U.S.

Our objectives were (1) to identify patterns or trajectories of long-term opioid therapy (LTOT) and their correlates among patients with and without cancer and (2) to assess the association between trajectories and risk for opioid overdose, considering the potential moderating role of cancer.
Methods And Analysis: We conducted a retrospective cohort study among individuals in the US Veterans Health Administration (VHA) database with incident LTOT with and without cancer (N=44,351; N=285,772, respectively) between 2010-2017.
Objective: To determine changes in opioid prescribing among veterans with headaches during the coronavirus disease of 2019 (COVID-19) pandemic by comparing the stay-at-home phase (March 15 to May 30, 2020) and the reopening phase (May 31 to December 31, 2020).
Background: Opioid prescribing for chronic pain has declined substantially since 2016; however, changes in opioid prescribing during the COVID-19 pandemic among veterans with headaches remain unknown.
Methods: This retrospective cohort study utilized regression discontinuity in time and difference-in-differences design to analyze veterans aged ≥18 years with a previous diagnosis of headache disorders and an outpatient visit to the Veterans Health Administration (VHA) during the study period.
