Addition of community paramedics to a physician home-visit program: A prospective cohort study.

BACKGROUND: Home-based primary care promotes aging in place but is not immediately responsive to urgent needs. Community paramedicine leverages emergency medical services clinicians to expedite in-home care, though limited evidence supports this model. We evaluated the primary care and acute care use of older adults evaluated urgently by a community paramedic with telemedicine physician compared to a physician home visit model. METHODS: This prospective cohort study enrolled older adults in home-based primary care who requested an urgent evaluation. We allocated participants to the physician home visit model or physician home visit plus community paramedic model by ZIP code. We observed primary care and acute care use for 6 months following enrollment. The primary outcome was the median number of primary care and acute care visits per participant. Secondary outcomes included 30-day readmission rates, median wait times, and physician productivity. Data analysis included descriptive statistics, comparison of means and proportions, and negative binomial regression modeling reported as incidence rate ratios (IRR). RESULTS: We screened 255 participants, determined 203 eligible, allocated 199, and completed observation for 167 (84 community paramedicine, 83 physician home visit). Participants were mostly female, age 76-86 years, with 3-5 comorbidities, living in a home/apartment. Community paramedic participants had 29% more primary care visits (IRR 1.29, 95% confidence interval [CI] 1.06-1.57) and shorter wait times for urgent evaluations (1 vs. 5 days, p < 0.001) without increasing acute care use (IRR 0.75, 95% CI 0.48-1.18) or 30-day readmissions (IRR 1.32, 95% CI 0.49-3.55). Physician productivity increased 81% (40 vs. 22 visits/week, p < 0.001). CONCLUSION: Older adults evaluated by a community paramedic for urgent needs were seen sooner, used acute care similarly to patients evaluated by a physician home visit, and nearly doubled physician efficiency. This suggests that older adults may benefit from combining emergency medical services and primary care resources for urgent evaluations.

A mixed-methods evaluation of home-based primary care in dementia within an integrated system.

BACKGROUND: No prior studies have examined the effects of home-based primary care (HBPC) in persons living with dementia (PLWD), within an ecosystem of serious illness care in an integrated healthcare system. Our objectives were to compare the characteristics of PLWD receiving HBPC and their hospital utilization and end-of-life care, with those of a matched comparison group, and to understand the experiences of family caregivers of PLWD receiving HBPC. METHODS: This mixed-methods study used a retrospective observational cohort design with PLWD receiving HBPC (n = 287) from 2015 to 2020 and a strata-matched comparison group (n = 861), and qualitative phone interviews with 16 HBPC family caregivers in 2020. Inverse probability of treatment weighting propensity score-adjusted models were used to compare time-to-first hospital-based utilization and, for decedents, home palliative and hospice care and place of death. Care experience was captured through caregiver interviews. RESULTS: Patients receiving HBPC had a similar risk of hospital utilization [adjusted hazard ratio, 1.06 (95% CI: 0.89-1.26), p = 0.51] as a matched non-HBPC comparison group after a median follow-up of 199 days. However, HBPC decedents (n = 159) were more likely to receive home palliative care or hospice [rate ratio, RR: 1.23 (95% CI: 1.07-1.42), p < 0.01] and to die at home [RR: 1.66 (95% CI: 1.35-2.05), p < 0.001] than were non-HBPC decedents (n = 423). Caregivers reported that HBPC provided coordinated, continuous, and convenient care that was aligned with families' priorities and goals; however, some expressed unmet needs, especially for help paying for personal care and medical supplies/equipment, and a desire for clearer communication about program operations and more quality oversight for contract services. CONCLUSIONS: Although HBPC for PLWD was associated with a similar risk of hospital utilization compared to a matched non-HBPC comparison group, HBPC resulted in more patient-centered end-of-life care for decedents. Prospective studies of HBPC that further elicit and address unmet needs are warranted.

Derivation and Validation of a Predictive Algorithm for Long-Term Care Admission or Death.

OBJECTIVES: Older veterans prefer to remain in their homes and communities as long as possible. Although targeted delivery of home- and community-based services for veterans might delay long-term care placement, often, access to these services is inconsistently organized or delayed. To aid in early recognition of veterans at high risk for long-term care placement or death, we developed and validated a predictive algorithm, "Choose Home." DESIGN: A retrospective observational cohort analysis was used. SETTING AND PARTICIPANTS: Two cohorts of Veterans Health Administration (VHA; a large integrated health care system) users were assembled: Derivation (4.6 million) and Confirmation (4.7 million). The Derivation Cohort included Veterans Administration users from fiscal year 2013; the Confirmation Cohort included Veterans Administration users from fiscal year 2014. METHODS: A total of 148 predictor variables, including demographics, comorbidities, and utilizations were selected using logistic regression to predict placement in a long-term care facility for >90 days or death within 2 years. RESULTS: Veterans were predominantly male [92.8% (Derivation), 92.5% (Confirmation)] and older [61.7±15.5 (Derivation), 61.5±15.6 years (Confirmation)], with a high prevalence of comorbid conditions. Between the Derivation and Confirmation Cohorts, the areas under the receiver operating characteristic curves were found to be 0.80 [95% confidence interval (CI) 0.799, 0.802] and 0.80 (95% CI 0.800, 0.802), respectively, indicating good discrimination for determining at-risk veterans. CONCLUSIONS AND IMPLICATIONS: We created a predictive algorithm that identifies veterans at highest risk for long-term institutionalization or death. This algorithm provides clinicians with information that can proactively inform clinical decision making and care coordination. This study provides the groundwork for future investigations on how home- and community-based services can target older adults at highest risk to extend time in their communities.

Telehealth in Home-Based Primary Care: Factors and Challenges Associated With Integration Into Veteran Care.

OBJECTIVES: To describe the structural characteristics and challenges associated with home telehealth (HT) use in the US Department of Veterans Affairs (VA) Home-Based Primary Care (HBPC) program. DESIGN: We designed a national survey to collect information about HBPC program structural characteristics. The survey included eight organizational and service domains, one of which was HT. HBPC program directors were surveyed online using REDCap. PARTICIPANTS: We received 232 surveys from 394 HBPC sites (59% response rate). METHODS: HBPC structural domains were compared between sites using and not using HT technology. Open-ended responses were analyzed using content analysis. RESULTS: A total of 127 sites (76%) used HT, which was more likely when HBPC sites were aligned organizationally with the VA's Geriatrics and Extended Care Services division, when there were more disciplines on the HBPC team, and when primary care providers made home visits. Program directors overwhelmingly viewed HT as contributing to managing veterans' complex chronic conditions (81%), yet HT data were not readily integrated into care planning (24%). Challenges to HT use included veterans' acceptance and adherence, device issues, and collaboration between HBPC teams and HT staff. CONCLUSION: Corresponding to HBPC's complexity, HT use is primarily a self-organizing process that shapes the patterns of integration at each site. Although HT technology is compatible with core structures of the HBPC model, usability varies, and overall is low. To optimize HT use in HBPC, there are opportunities to redesign systems to mitigate challenges to adoption. As the Centers for Medicare and Medicaid Services' strives to increase access to both HBPC and telehealth benefits, evidenced by the continuation of its successful Independence at Home demonstration and the final changes in the proposed rule in April 2019 incorporating additional telehealth benefits for beneficiaries, this information will be relevant to VA and non-VA alike.

The effects of home-based primary care on Medicare costs at Spectrum Health/Priority Health (Grand Rapids, MI, USA) from 2012-present: a matched cohort study.

BACKGROUND: In the United States, home-based primary care (HBPC) is increasingly proposed as a means of enabling frail elders to remain at home for as long as possible, while still receiving needed medical care. However, there are relatively few studies of either the medical outcome effects or cost benefits of HBPC. In this paper, we examine medical cost and mortality outcomes for enrollees in the HBPC program offered by Spectrum Health/Priority Health (SH/PH), a not-for-profit integrated health care/health insurance system located in Grand Rapids, MI, USA. METHODS: We perform a concurrent matched cohort study. SH/PH HBPC enrollees during 2012-2014 are matched for prior costs, age, sex and comorbidities against controls selected from unenrolled insurance plan members. Twelve and twenty four-month medical costs are compared between HBPC participants and matched controls, overall and conditional on mortality status. Mortality rates of HBPC participants are studied on their own and in comparison to controls. RESULTS: At 12 and 24 months, in comparison to matched controls HBPC participants show higher ($2933) and lower ($8620) costs respectively. Relative costs and savings of HBPC participants are a function of short term increased costs upon entry into the program (enrollees who survive the first year cost $5866 more than controls); substantial savings at end-of-life (approximately $37,037 in savings relative to controls are realized); and the overall mortality of HBPC participants (mean residual lifespan is 37.75 months from the time of enrollment). We project the present value of lifetime medical cost savings due to enrollment in the HBPC program to be at least $14,336. CONCLUSIONS: The SH/PC HBPC program reduces healthcare costs while enabling frail elders to remain at home. Reduction in costs is obtained at end-of-life and is offset with a smaller initial increase in costs upon enrollment.

It 'makes you feel more like a person than a patient': patients' experiences receiving home-based primary care (HBPC) in Ontario, Canada.

The lack of effective systems to appropriately manage the health and social care of frail older adults - especially among those who become homebound - is becoming all the more apparent. Home-based primary care (HBPC) is increasingly being promoted as a promising model that takes into account the accessibility needs of frail older adults, ensuring that they receive more appropriate primary and community care. There remains a paucity of literature exploring patients' experiences with HBPC programmes. The purpose of this study was to explore the experiences of patients accessing HBPC delivered by interprofessional teams, and their perspectives on the facilitators and barriers to this model of care in Ontario, Canada. Using certain grounded theory principles, we conducted an inductive qualitative content analysis of in-depth patient interviews (n = 26) undertaken in the winter of 2013 across seven programme sites exploring the lived experiences and perspectives of participants receiving HBPC. Themes emerged in relation to patients' perceptions regarding the preference for and necessity of HBPC, the promotion of better patient care afforded by the model in comparison to office-based care, and the benefits of and barriers to HBPC service provision. Underlying patterns also surfaced related to patients' feelings and emotions about their quality of life and satisfaction with HBPC services. We argue that HBPC is well positioned to serve frail homebound older adults, ensuring that patients receive appropriate primary and community care - which the office-based alternative provides little guarantee - and that they will be cared for, pointing to a model that may not only lead to greater patient satisfaction but also likely contributes to bettering the quality of life of a highly vulnerable population.
