Expanding Home-Based Primary Care to American Indian Reservations and Other Rural Communities: An Observational Study.

Home-based primary care (HBPC) is a comprehensive, interdisciplinary program to meet the medical needs of community-dwelling populations needing long-term care (LTC). The U.S. Department of Veterans Affairs (VA) expanded its HBPC program to underserved rural communities, including American Indian reservations, providing a "natural laboratory" to study change in access to VA LTC benefits and utilization outcomes for rural populations that typically face challenges in accessing LTC medical support. Pretest-Posttest quasi-experimental approach with interrupted time-series design using linked VA, Medicare, and Indian Health Service (IHS) records. American Indian reservations and non-Indian communities in rural HBPC catchment areas. 376 veterans (88 IHS beneficiaries, 288 non-IHS beneficiaries) with a HBPC length of stay of 12 months or longer. Baseline demographic and health characteristics, activities of daily living (ADL), previous VA enrollment, and hospital admissions and emergency department (ED) visits as a function of time, accounting for IHS beneficiary and functional statuses. For HBPC users, VA enrollment increased by 22%. At baseline, 30% of IHS and non-IHS beneficiaries had 2 or more ADLs impairments; IHS populations were younger (P < .001) and had more diagnosed chronic diseases (P = .007). Overall, hospital admissions decreased by 0.10 (95% confidence interval (CI) = -0.14 to -0.05) and ED visits decreased by 0.13 (95% CI = -0.19 to -0.07) in the 90 days after HBPC admission (Ps < .001) and these decreases were maintained over 1 year follow-up. Before HBPC, probability of hospital admission was 12% lower for IHS than non-IHS beneficiaries (P = .02). Introducing HBPC to rural areas increased access to LTC and enrollment for healthcare benefits, with equitable outcomes in IHS and non-IHS populations.

Improving access to noninstitutional long-term care for American Indian veterans.

Home-based primary care (HBPC) is an effective model of noninstitutional long-term care developed in the Department of Veterans Affairs (VA) to provide ongoing care to homebound persons. Significant rural populations of American Indians have limited access to services designed for frail older adults. Fourteen Veterans Affairs Medical Centers (VAMCs) initiated efforts to expand access to HBPC in concert with local tribes and Indian Health Service (IHS) facilities. This study characterizes the resulting emerging models of HBPC and co-management. Using an observational design, key respondent telephone interviews (n = 37) were conducted with stakeholders representing the 14 VAMCs to describe these HBPC programs, and HBPC models were evaluated in relation to VAMC organizational culture as revealed on the annual VA All Employee Survey. Twelve VAMCs independently developed HBPC expansion programs for American Indian veterans, and six different program models were implemented. Two models were unique to collaborations between VAMCs and tribes; in these collaborations, the tribes retained primary care responsibilities. VAMC used the other four models for delivery of care in remote rural areas to all veteran populations, American Indians and non-Indians alike. Strategies to improve access by reducing geographic barriers occur in all models. Comparing mean VAMC organizational culture ratings, as defined in the Competing Values Framework, revealed significant group differences for one of these six models. Findings from this study illustrate the flexibility of the HBPC program and opportunities for co-management and expansion of healthcare access for American Indians and non-Indians, particularly in rural areas.

Better access, quality, and cost for clinically complex veterans with home-based primary care.

In successfully reducing healthcare expenditures, patient goals must be met and savings differentiated from cost shifting. Although the Department of Veterans Affairs (VA) Home Based Primary Care (HBPC) program for chronically ill individuals has resulted in cost reduction for the VA, it is unknown whether cost reduction results from restricting services or shifting costs to Medicare and whether HBPC meets patient goals. Cost projection using a hierarchical condition category (HCC) model adapted to the VA was used to determine VA plus Medicare projected costs for 9,425 newly enrolled HBPC recipients. Projected annual costs were compared with observed annualized costs before and during HBPC. To assess patient perspectives of care, 31 veterans and caregivers were interviewed from three representative programs. During HBPC, Medicare costs were 10.8% lower than projected, VA plus Medicare costs were 11.7% lower than projected, and combined hospitalizations were 25.5% lower than during the period without HBPC. Patients reported high satisfaction with HBPC team access, education, and continuity of care, which they felt contributed to fewer exacerbations, emergency visits, and hospitalizations. HBPC improves access while reducing hospitalizations and total cost. Medicare is currently testing the HBPC approach through the Independence at Home demonstration.
