Abstract and Introduction
Stroke is a leading cause of mortality and disability in the United States.[1,2] Approximately 800,000 American adults experience a stroke each year.[2,3] Currently, approximately 6 million stroke survivors live in the United States. Participation in stroke rehabilitation (rehab), which occurs in diverse settings (i.e., in-hospital, postacute care, and outpatient settings), has been determined to reduce stroke recurrence and improve functional outcomes and quality of life.[3,4] Despite longstanding national guidelines recommending stroke rehab, it remains underutilized, especially in the outpatient setting. Professional associations and evidence-based guidelines support the increasing stroke rehab use in health systems and are promoted by the public health community.[3–6] An analysis of 2005 Behavioral Risk Factor Surveillance System (BRFSS) data revealed that 30.7% of stroke survivors reported participation in outpatient rehab for stroke after hospital discharge in 21 states and the District of Columbia (DC). To update these estimates, 2013 and 2015 BRFSS data were analyzed to assess outpatient rehab use among adult stroke survivors. Overall, outpatient rehab use was 31.2% (20 states and DC) in 2013 and 35.5% (four states) in 2015. Disparities were evident by sex, race, Hispanic origin, and level of education. Focused attention on system-level interventions that ensure participation is needed, especially among disparate populations with lower levels of participation.
BRFSS is a telephone survey of the noninstitutionalized U.S. population* conducted annually by all states. The cardiovascular health module, which includes questions about rehab participation, was an optional module in 2013 and 2015. In 2013, the median cardiovascular health module response rate† for 20 states§ was 46.2%. Among the four states¶ participating in the module in both 2013 and 2015, the response rate was 49.3% in 2013 and 51.5% in 2015.
Stroke survivors were identified by the question "Has a doctor, nurse, or other health professional ever told you that you had a stroke?" Participation in outpatient stroke rehab was only asked of those with a history of stroke and was identified among respondents who answered "yes" to the question "Following your stroke, did you go to any kind of outpatient rehabilitation?" Demographic characteristics collected included age, sex, race, Hispanic origin, education (less than high school, high school graduate, some college, or college graduate) and health insurance status. Selected cardiovascular disease risk factors included hypertension, high blood cholesterol, diabetes, obesity, and current smoking. Percentages of respondents who participated in stroke rehab were measured, overall, by demographic characteristics, by cardiovascular disease risk factors in 2013, and by state of residence, and were adjusted for age, sex, race/Hispanic origin, education, insurance status, presence of cardiovascular disease risk factors, and number of cardiovascular disease risk factors (0, 1, 2, 3, 4, or 5). Adjusted percentages and 95% confidence intervals (CIs) were calculated; p-values <0.05 (obtained using Wald F test) were regarded as statistically significant. Statistical software was used to account for the complex sampling design.
In 2013, among 168,655 BRFSS participants, 3.3% (95% CI = 3.1%–3.4%) reported a history of stroke and were classified as stroke survivors. In 2015, among 21,047 participants, 3.3% (95% CI = 3.0%–3.8%) were stroke survivors. In 2013, stroke outpatient rehab participation was 31.2% (95% CI = 29.1%–33.4%) (Table 1). Men, non-Hispanic blacks, and those with a college education or higher more frequently reported participating in stroke outpatient rehab than did women, non-Hispanic others, Hispanics, and those with less than a high school education.
Total adjusted outpatient rehab participation was 31.2% in 2013 and 35.5% in 2015 (Table 2). In 2013, adjusted percentages ranged from 23.1% in Oregon to 43.6% in Minnesota. The unadjusted and adjusted percentages of stroke survivors who took part in outpatient rehab in 2015 were lowest in Maine (28.0% and 31.3%, respectively) and highest in Iowa (46.1% and 49.8%, respectively). Among the four states that included stroke outpatient rehab questions in both 2013 and 2015, the overall adjusted percentage of stroke outpatient rehab participation increased 8.3 percentage points, from 27.2% in 2013 to 35.5% in 2015 (p<0.05).
