BackgroundIncome disparities may affect patients’ care transition home. Evidence among patients who have access to publicly funded healthcare coverage remains limited.ObjectiveTo evaluate the association between low income and post-discharge health outcomes and explore patient and caregiver perspectives on the role of income disparities.DesignMixed-methods secondary analysis conducted among participants in a double-blind randomized controlled trial.ParticipantsParticipants from a multicenter study in Ontario, Canada, were classified as low income if annual self-reported salary was below $29,000 CAD, or between $30,000 and $50,000 CAD and supported ≥ 3 individuals.Main MeasuresThe associations between low income and the following self-reported outcomes were evaluated using multivariable logistic regression: patient experience, adherence to medications, diet, activity and follow-up, and the aggregate of emergency department (ED) visits, readmission, or death up to 3 months post-discharge. A deductive direct content analysis of patient and caregivers on the role of income-related disparities during care transitions was conducted.Key ResultsIndividuals had similar odds of reporting high patient experience and adherence to instructions regardless of reported income. Compared to higher income individuals, low-income individuals also had similar odds of ED visits, readmissions, and death within 3 months post-discharge. Low-income individuals weremorelikely than high-income individuals to report understanding their medications completely (OR 1.9, 95% CI: 1.0–3.4) in fully adjusted regression models. Two themes emerged from 25 interviews which (1) highlight constraints of publicly funded services and costs incurred to patients or their caregivers along with (2) the various ways patients adapt through caregiver support, private services, or prioritizing finances over health.ConclusionsThere were few quantitative differences in patient experience, adherence, ED visits, readmissions, and death post-discharge between individuals reporting low versus higher income. Several hidden costs for transportation, medications, and home care were reported however and warrant further research.Supplementary InformationThe online version contains supplementary material available at 10.1007/s11606-023-08024-7.
