"No place like home: impact of the House Calls model on ED visits, hospitalizations and time in the community"

Home-based primary care in Canada is currently greatly under-powered, despite an aging population, an increasing proportion of homebound older adults,1 and 100% of Canadians hoping to age at home.2 Homebound older adults in Canada have increased comorbidities, medications and mental diagnoses compared to their non-homebound peers.3,4 They have difficulty accessing office-based care due to a combination of physical, mental and social frailty, resulting in higher emergency department (ED) visits and hospitalization rates.4 Our team, House Calls, reaches homebound adults with further identities that may impact equitable care, including racialized older adults, newcomers, those with English as a second language, adults with disabilities and the precariously housed. House Calls is a unique not-for-profit home-based primary care team in Toronto, Canada. It was founded in 2007 through consultation with local older adults, caregivers and service providers identifying the type of services that mattered most to their care. It was further developed in collaboration with local community partners. The team is a health worker-led multidisciplinary team, with physicians, nurse practitioners, occupational therapists, physiotherapists, social workers and administrators working together in a horizontal, trust-rooted leadership structure. Through regular intra-team consultation and annual patient/caregiver surveys, the team evolves its operational structure responsively to patient and community needs. The goal of House Calls is to help homebound older adults age and die in place, through a three-pronged program: geriatric-focused interdisciplinary primary care, urgent care support and home-based palliative care. We designed a retrospective cohort study to assess rates of hospitalization, ED visits and time spent in the community for House Calls patients from January 1, 2015 to January 1, 2022, when compared to similarly frail, homebound older adults in the same geographic areas. The study will also measure House Calls program implementation, through rates of interprofessional and urgent care visits. Study results are pending. We hypothesize that this home-based primary care model results in reduced ED visits and hospitalizations, and more successful aging at home as measured by time spent in the community. Through the description of this program and its evaluation, we hope to contribute valuable, evidence-based knowledge to inform the care of older adults, in a challenging international climate of aging populations, limited research and often stigma-based funding challenges. We hope to use our results to improve the quality of care offered at House Calls, and inform wider implementation of similarly structured home-based primary care teams.
