Background
Population aging has led to an increasing number of older adults living in the community with complex care needs such as functional limitations, cognitive impairment, and multimorbidity. These individuals may need help to remain in their homes, which has created a growing demand for home care. Strategies to manage complex older adults such as home care patients safely in the community typically emphasize robust and integrated primary care. The objective of this thesis is to explore how specific measures of quality in primary care are associated with emergency department use among home care patients in Ontario.
Methods
I conducted four studies on varying subsets of the same population-based retrospective cohort of long-stay home care patients assessed in Ontario from 2014-2016. The first study was a descriptive examination of the entire cohort that characterized their primary care and other health system use. The second was a case-crossover study among home nursing patients examining whether access to afterhours care modifies the association between home nursing visits and same-day emergency department visits. The third study looked at physician-level provision of primary care home visits and its association with emergency department visits among home care patients with extensive functional impairments. The final study examined and compared associations between continuity of primary and specialty physician care.
Results
Long-stay home care patients in Ontario are high users of both primary care and the emergency department. Better access to afterhours care reduced the likelihood of an emergency department visit on the same day as a home nursing visit. Patients with extensive functional impairments whose primary care physician who provided higher levels of home visits had lower rates of emergency department use. Finally, better continuity of both primary and specialty physician care were similarly associated with lower emergency department use.
Conclusion
Better quality primary care integrated with other sectors of the health system is crucial to enabling home care patients to age safety in the community. Access to care is particularly important and can be improved though enhancing the availability of afterhours care and increasing the provision of home visits for those who have difficulty reaching primary care offices. Improving continuity of specialty physician care should be a health system objective alongside improving continuity of primary care. / Thesis / Doctor of Philosophy (PhD) / Older adults receiving home care are a growing population of individuals with complex care needs and high rates of emergency department use. This thesis seeks to characterize the primary care use of home care patients in Ontario and examine to what degree better quality of primary care is associated with less use of the emergency department. My findings indicate that increased access to afterhours primary care, higher levels of primary care home visits, and better continuity of both primary and specialty physician care were associated fewer emergency department visits. In conjunction with other sectors, primary care plays a central role managing older adults with complex care needs in the community. Better quality of primary care, particularly advanced access, can help keep older adults safely at home and out of hospitals as they age.
