Residential migration among Veterans with experience of housing instability

Abstract: Housing instability is an important determinant of health and can lead to reduced life expectancy as well as other poor outcomes. While homelessness is often perceived as an urban phenomenon, it is also present in rural areas of the U.S. Compared with non-Veterans, Veterans are more likely both to be living in rural areas and experiencing housing instability. The U.S. Department of Veterans Affairs (VA) offers health care and social services—including a variety of responses to housing instability—in facilities across the U.S. The objective of the present study is to estimate the frequency of migration among Veterans with experience of homelessness, the characteristics of their migrations, and individual and community-level characteristics that may predict their migrations. We used VA administrative data for 559,513 Veterans with an indicator of housing instability between January 1, 2014, and December 31, 2018, with up to a 5-year observation period. The primary outcome of interest was migration, defined as a single geographic residential relocation (i.e., a change of residential address) of more than 40 miles or a geographic residential relocation of fewer than 40 miles but with a change in urban/rural status. Controlling for a variety of covariates, we utilized a discrete-time survival framework with person-quarter as the unit of analysis; this allowed us to directly model event rates over time with the inclusion of time-varying predictors. Across the observation period, about one-quarter of Veterans with an indicator of housing instability migrated, most frequently those who resided in a rural area and sought care at an urban facility; the majority migrated to or within an urban area and these migrations were of a greater distance than migrations to or within a rural area. Future work in this area should focus on investigating differences in findings across geographic regions, Veterans' reasons for migration, and the impact of migration on Veterans’ health and housing outcomes.

    Effects of Veterans Affairs access expansions on inpatient care for women Veterans

    Abstract: Background: Enactment of the Veterans Choice Act (VCA) in 2014 and expansion of Medicaid programs led to greater options for Veterans to receive health care outside of the U.S. Department of Veterans Affairs (VA). However, little is known about how much care women Veterans receive in VA or non-VA settings paid by VA or other insurance types. We explore trends in inpatient care received by women Veterans before and after implementation of the VCA, focusing on hospitalizations, as these patients are often higher risk. Methods: Data for women Veterans were linked to hospital discharge data for 2013-2017 from 11 diverse states. Patient and hospital characteristics by VA and non-VA payer and age group (less than 65 years and 65 years and older) were compared for acute hospitalizations in Pearson's chi-square and analysis of variance tests. We compared the odds of a hospitalization occurring before and after VCA implementation for each specific setting/payer using separate logistic regressions. Results: Our sample included 117,177 acute medical/surgical hospitalizations. For younger women, the most common hospital setting/payer was VA hospitals (36%); older women most frequently received hospital care in non-VA hospitals covered by Medicare (61%). After the VCA, the probability of receiving VA-purchased care increased significantly for older women only. Younger women saw a significant decrease in VA hospitalizations post-VCA. Conclusions: We found that after multiple expansions in non-VA health care options, women Veterans sought more VA-purchased community hospital care.
