Abstract:

BACKGROUND: Although cardiac rehabilitation (CR) has established benefits for cardiovascular health, it remains significantly underutilized, with substantial differences in participation related to factors such as educational attainment (EA), race, and ethnicity. We studied a geographically and racially diverse cohort of insured individuals in a health claims database to (1) evaluate differences in CR participation by EA and race or ethnicity and (2) assess how EA modifies associations between race or ethnicity and CR participation. METHODS: We conducted a retrospective cohort study of individuals identified in Optum's de-identified Clinformatics® database between 1/1/2016 and 12/31/2019. Eligible individuals included those aged 18 years with a hospitalization for an incident CR-qualifying diagnosis. We calculated incidence rates of CR enrollment by EA and race or ethnicity, as well as associations of EA and race or ethnicity with CR enrollment, and evaluated interaction between EA and race or ethnicity with respect to CR participation. RESULTS: We identified 171,297 individuals eligible for CR with a mean ± SD age of 70.4 ± 11.6 years; 37.4 % were female, and 68.3 % had > high school education. We observed a dose-response association between EA and rate of participation in CR. After adjustment, compared to White individuals, the odds of attending CR was 24 % lower for Asian individuals [95 % confidence interval (CI): 17 %, 30 %], 13 % lower for Black individuals (95 % CI: 9 %, 17 %), and 32 % lower for Hispanic individuals (95 % CI: 28 %, 35 %), all p < 0.0001. However, Black individuals with bachelor's degree had a similar odds of CR enrollment as White individuals with bachelor's degree (odds ratio 1.01, 95 % CI: 0.85, 1.20, p = 0.95). CONCLUSIONS: EA was positively associated with CR enrollment across racial and ethnic groups. Higher EA might partially attenuate racial and ethnic differences in CR participation, but significant disparities persist. Our findings support increased attention to individuals with limited education to improve CR enrollment.
