County-level impact of the COVID-19 pandemic on excess mortality among U.S. veterans: a population-based study.
This study investigated the county-level impact of the COVID-19 pandemic on excess mortality among U.S. veterans. The authors queried Veterans Health Administration (VHA) administrative data on demographics and comorbidities for 11.4 million enrollees during 2016-2020. Eight mortality prediction models at the county-level were used including Poisson, Poisson quasi-likelihood, negative binomial, and generalized estimating equations. All models demonstrated excellent agreement between observed and predicted mortality. An excess mortality rate of 13% in 2020 was found, which corresponds to 50,299 excess deaths. Despite mortality risk factors of veterans, their excess mortality rate was slightly lower than the general population.

How does geographic access affect in-hospital mortality for veterans with acute ischemic stroke?
This study examined the relationship between estimated travel time to admitting hospital and mortality for veterans with acute ischemic stroke. It found that even after adjusting for the confounding effects of patient, treatment, and facility characteristics, travel time from home to admitting VAMC was significantly associated with inhospital mortality.
