Disparities in Access to, Use of, and Quality of Rehabilitation After Stroke in the United States: A Scoping Review

To summarize current reports in the literature on disparities in rehabilitation after stroke; identify gaps in our understanding of rehabilitation disparities; and make recommendations for future research. A health sciences librarian developed a search string based on an a priori protocol and searched Medline (Ovid) Embase (Elsevier), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL and EBSCO). A 2-step screening process of titles and abstracts followed by full-text review was conducted. Primary observational studies conducted in the United States that reported on disparities in rehabilitation (ie, physical, occupational, or speech therapy) among adults after stroke were retained. Eligible disparity populations included racial minorities; ethnic minorities; sex and gender minorities; older populations; socioeconomically disadvantaged populations; and geographic minorities (inner city/rural). Data extracted from retained articles included: aims/objectives; data source; sample characteristics, rehabilitation outcomes examined; types of disparities examined; statistical methods used; and disparity findings. Seven thousand eight hundred fifty-three titles and abstracts were screened, and 473 articles underwent full-text review. Forty-nine articles were included for data extraction and analysis. Many articles examined more than 1 disparity type with most examining disparities in race and/or ethnicity (n=43, 87.7%), followed by sex (n=25, 53.0%), age (n=23, 46.9%), socioeconomic status (n=22, 44.9%), and urban/rural status (n=8, 16.3%). Articles varied widely by sample characteristics, data sources, rehabilitation outcomes, and methods of examining disparities. Although we found some consistent evidence of disparities in rehabilitation for older individuals, non-White races, and individuals of lower socioeconomic status, the variability in methods made the synthesis of findings challenging. Further work, including additional well-designed studies and systematic reviews, and/or meta-analyses of current studies, is needed to better understand the extent of rehabilitation disparities after stroke.
