The majority of Class 1 and Class 2 veterans accessed the HISA from their nearest facility. However, nearly one-quarter of both Class 1 and 2 RHUs (24% each) did not. Among the 2598 who accessed the nonnearest facility, 97 (3.7%) accessed a facility that is ≤ 40 miles. Many (44%) users traveled 40 to 100 miles, and another 43.2% traveled 100 to 200 miles from their residence to access a HM prescription. Some 2598 users (1.1%) traveled > 500 miles to access a facility.
Discussion
Although utilization of the HISA program has steadily increased, overall participation by subpopulations such as RHUs can still be improved significantly. Veterans aged ≤ 46 years who have a disability that is common to those receiving HISA benefits have low HISA utilization. Similarly, veterans with sensory disabilities also have low use. These subpopulations are among those in great need of attention and services.
A study by Lucas and Zelaya, using the 2016 National Health Interview Survey data with an aim to measure degree of vision problems, dual sensory impairment, and hearing trouble in male veterans aged ≥ 18 years, found that veterans were more likely to report dual sensory impairment and balance difficulties when compared with nonveterans.9 The number of female veterans is growing but had very low representation in this study.10 This emerging VHA population requires information and education on their HM benefits.
Home Modifications
The most common HM prescribed for RHUs was for the bathroom. Further investigation is warranted as to why, given the diversity of HM types that the grant covers, low prescription rates exist across most of the HM types. There may be a lack of knowledge by providers and VWD as to the range of HMs that can be awarded under the grant. It is important that HCPs and veterans receive education on HISA HM options.
Semeah and colleagues pointed out the need for an assessment of the HISA HM ordering system to ensure that multiple HMs items (eg, kitchen, air conditioning, fees, driveway, and plumbing) are listed among the forced choices shown to clinicians to select from.7 Poor housing in rural America is widespread: 63% of rural dwellings need renovations and/or repairs to be accessible to individuals with disabilities, with > 6.7 million rural homes having no or faulty plumbing or kitchens; yet in this study, prescriptions for these HMs accounted for < 1%.11,12
VISN 6 had the most HISA awards with 1364, while VISN 21 had the fewest (245). Across all VISNs, Class 1 RHUs received more prescriptions than did Class 2 RHUs. Future research may seek to examine whether prescribers are fully aware of the eligibility of HM prescription to Class 2 veterans. VISN 21 ($5354); VISN 17 ($5302); and VISN 6 ($5301) had the highest mean HM expenditures. The national mean cost for HISA HMs were $4978 for bathrooms and $4305 for kitchens; for non-HISA HMs in FY 2017, the mean costs were $6362 and $12,255, respectively. A noteworthy concern is whether the maximum grant limit awards are sufficient to perform more expensive and complex HMs, such as the kitchen or major bathroom alternations.13
Facilities categorized as 1a, 1b, or 1c provided prescription to more than 70.7% of all RHUs. Embedded in the infrastructures of these higher complexity level facilities are substantial research and education opportunities for staff and patients and a diversity of medical specialties. Attention must be provided to less resourced facilities located in rural areas or serving many RVs that may not have the infrastructure to monitor the HISA process or make it available to VWDs. Furthermore, the top prescribing VAMCs were almost all high-complexity facilities, and all served > 100 unique RHUs. Further research may be warranted to be better understand the variation in HM prescriptions at VAMCs.
North Florida/Sough Georgia was the highest-prescribing VAMC with 39% more HM prescriptions than the second highest prescribing facility (Durham, NC). Unfortunately, the data presented here cannot establish causality for the large variance difference between the top facilities, and the skewed distribution of total RHUs across VAMCs.
