Background:
Socioeconomic status (SES) is widely recognized as an area of inequity that affects health outcomes. However, social determinants of health are less frequently measured in longitudinal studies of acute stroke patients. The relationship of SES on disability 3-months post-stroke is unknown.
Methods:
We analyzed ischemic stroke patients in the AVAIL registry who were enrolled at 98 hospitals participating in Get With The Guidelines-Stroke. Patients who died (n=64) or did not complete a modified Rankin Scale (mRS) at 3-months (n=154) were excluded. Multivariable logistic regression was used to examine the relationship of SES (defined by level of education, work status, and perceived adequacy of household income to meet needs) and disability (mRS scores 3-5).
Results:
Among the 2092 stroke patients who met eligibility criteria, the mean age was 65.5 ± 13.7, 44.2% were female, and 82.7% were White. Fifty seven percent had a high school or less education, 11.4% were not working post-stroke and were home not by choice, and 25.7% were without an adequate household income. A third of the sample had some level of disability at 3-months (34.6% mRS 3-5). Those with disability were more likely to be older, non-White, female, single, less educated, have inadequate income, and were home not by choice. In the multivariable analysis, lower education, inadequate income, and being home but not by choice (compared with those who returned to work) were independently associated with disability (p<0.01;

Conclusion:
In this national cohort of stroke survivors, socioeconomic status as measured by level of education, work status, and income were independently associated with post-stroke disability.
