Quality in primary care and use of the emergency department among home care patients
Bibliographic record
Abstract
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
