Temporal Trends in the Unmet Health Care Needs of Canadian Stroke Survivors

Abstract

Background: Stroke survivors have higher unmet health care needs than the general population. However, it is unclear whether such needs have changed over time, and whether these have been affected by the introduction of integrated systems of stroke care. Methods: We used data from the Canadian Community Health Surveys between 2000 and 2014. We developed multivariable log-binomial generalized estimating equations to obtain adjusted risk ratios (aRRs) of unmet health care needs in stroke survivors compared to the general population, and over time. We conducted a difference in differences analysis to determine the association between the implementation of integrated systems of stroke care and unmet health care needs. Results: Data from 350,084 respondents were included in the study; 8072 (2.3%) were stroke survivors. Compared to the general population, stroke survivors were more likely to report unmet health care needs (aRR 1.27; 95% CI, 1.22-1.32). The unmet health care needs reported by stroke survivors were lower after compared to before 2006 (15.8% vs. 31.9%, P < 0.001). After accounting for temporal trends, there was no association between the implementation of integrated systems of stroke care and change in unmet health care needs of stroke survivors. However, this requires cautious interpretation due to limitations in the data available for this study. Conclusions: Unmet health care needs of stroke survivors have reduced over time but remain higher than the general population. Future research should focus on identifying stroke- and policy-related factors to mitigate disparities in health care access for stroke survivors.
