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.

Preventing Hospitalization with Veterans Affairs Home-Based Primary Care: Which Individuals Benefit Most?

To examine how medical complexity modifies the relationship between enrollment in Department of Veterans Affairs (VA) home-based primary care (HBPC) and hospitalization for ambulatory care-sensitive conditions (ACSC) for veterans with diabetes mellitus and whether the effect of HBPC on hospitalizations varies according to clinical condition. Retrospective cohort study. VA and non-VA hospitals. VA beneficiaries aged 67 and older with diabetes mellitus and enrolled in Medicare (N = 364,972). Instrumental variables regression models were used to estimate the effect of HBPC enrollment on hospitalization for ACSCs (defined according to the Agency for Healthcare Research and Quality Prevention Quality Indicators) overall and in subgroups stratified according to medical complexity. Models were also estimated for each ACSC to determine which conditions were most sensitive to HBPC. Distance from the veteran's residence to the nearest HBPC site was used as the instrumental variable. HBPC was associated with fewer ACSC hospitalizations (odds ratio (OR) = 0.35 per person-month, 95% confidence interval (CI) = 0.30-0.42). For veterans in the highest quartile of medical complexity, HBPC enrollment was associated with fewer ACSC hospitalizations (OR = 0.43, 95% CI = 0.19-0.93), whereas for those in the lowest quartile, HBPC was associated with more ACSC hospitalizations (OR = 33.2, 95% CI = 4.6-240.1). HBPC enrollment was associated with fewer hospitalizations for a range of ACSCs. HBPC enrollment was associated with fewer hospitalizations for a range of ACSCs in veterans with diabetes mellitus but only in the most medically complex individuals. This demonstrates the importance of appropriate targeting and suggests that the effect of HBPC is attributable to its comprehensive approach rather than condition-specific interventions.

Effects of home-based primary care on Medicare costs in high-risk elders.

To determine the effect of home-based primary care (HBPC) on Medicare costs and mortality in frail elders. Case-control concurrent study using Medicare administrative data. HBPC practice in Washington, District of Columbia. HBPC cases (n = 722) and controls (n = 2,161) matched for sex, age bands, race, Medicare buy-in status (whether Medicaid covers Part B premiums), long-term nursing home status, cognitive impairment, and frailty. Cases were eligible if enrolled in MedStar Washington Hospital Center's HBPC program during 2004 to 2008. Controls were selected from Washington, District of Columbia, and urban counties in Virginia, Maryland, and Pennsylvania. HBPC clinical service. Medicare costs, utilization events, mortality. Mean age was 83.7 for cases and 82.0 for controls (P < .001). A majority of both groups was female (77%) and African American (90%). During a mean 2-year follow-up, in univariate analysis, cases had lower Medicare ($44,455 vs $50,977, P = .01), hospital ($17,805 vs $22,096, P = .003), and skilled nursing facility care ($4,821 vs $6,098, P = .001) costs, and higher home health ($6,579 vs $4,169; P < .001) and hospice ($3,144 vs. $1,505; P = .005) costs. Cases had 23% fewer subspecialist visits (P = .001) and 105% more generalist visits (P < .001). In a multivariate model, cases had 17% lower Medicare costs, averaging $8,477 less per beneficiary (P = .003) over 2 years of follow-up. There was no difference between cases and controls in mortality (40% vs 36%, hazard ratio = 1.06, P = .44) or in average time to death (16.2 vs 16.8 months, P = .30). HBPC reduces Medicare costs for ill elders, with similar survival outcomes in cases and controls.

National integration of mental health providers in VA home-based primary care: an innovative model for mental health care delivery with older adults.

To promote mental health (MH) service access and quality for veterans with complex and chronic medical, social, and behavioral conditions, the U.S. Department of Veterans Affairs (VA) has integrated a full-time MH provider into each VA home-based primary care (HBPC) team. The goal of the current evaluation is to examine the nature and extent to which MH care processes and practices have been integrated into HBPC nationally. Separate surveys assessing the integration of a wide range of MH care practices and HBPC team processes were sent to MH providers and program directors in each HBPC program in 2010. A total of 132 MH providers representing 119 HBPC programs, and 112 program directors completed the surveys. The most common clinical issues addressed by MH providers were depression, coping with illness and disability, anxiety, caregiver/family stress, and cognitive evaluation. Other team members typically conducted initial MH screenings, with MH providers' time focusing on cases with identified needs. Approximately 40% of MH providers' time was devoted to direct clinical care. Significant time was also spent on team activities, driving, and charting. Integration of MH services into HBPC is feasible and facilitates service access for a vulnerable population. Mental health care delivery in HPBC generally involves a high degree of interdisciplinary practice. Mental health integration into HBPC may serve as a model for other systems interested in promoting MH care delivery among homebound and other older individuals.
