Temporal Trends and Factors Associated With Cardiac Rehabilitation Referral Among Patients Hospitalized With Heart Failure

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): The Danish Heart Foundation Background Heart failure (HF) places a large burden on patients and society as a major cause of morbidity, mortality and healthcare costs. Participation in exercise-based cardiac rehabilitation (CR) in people with HF is a clinically and cost-effective strategy and recommended in international clinical guidelines. Purpose The aims of this study were to: (1) examine the temporal trends and predictors of national CR referral, and (2) compare the risk of hospital readmission and mortality in those referred for CR compared to no referral. Methods All patients in Denmark with incident HF were identified by the Danish Heart Failure Register in the period 2010 to 2018 (n = 33,257) and CR referral assessed within 120 days of hospital admission. Multivariable logistic regression models were used to evaluate the association between CR referral and predictors and to compare risk of hospital readmission and mortality until 1 year between referred and not referred patients. Results Overall, 45.0% of HF patients were referred to exercise-based CR, increasing from 31.7% in 2010 to 52.2% in 2018. Factors independently associated with higher CR referral were: NYHA functional class II, LVEF <50%, diagnosis of myocardial infarction and use of ACE inhibitor. Male gender, older age, region, unemployment, retirement, living alone, non-Danish ethnic origin, lower educational level, NYHA class IV, treatment for hypertension, existing chronic obstructive lung disease and stroke were associated with lower CR referral. CR referral was associated with lower risk of readmission (adjusted odds ratio: 0.90;95%CI: 0.85-0.95), HF-specific mortality (0.61; 0.39-0.95) and all-cause mortality (0.61; 0.55-0.69) as compared to no referral. Conclusions Although CR referral has increased over time, only some 1 in 2 diagnosed HF patients in Denmark are referred to exercise-based CR. CR referral is associated with lower risk in readmissions and mortality. Strategies to promote CR referral including healthcare professional education on the benefits of CR and alternative methods of CR delivery are urgently needed to improve access to CR, especially for high-risk groups.

Background: Heart failure has a disproportionate burden on patients who are Black, Indigenous, and people of color (BIPOC), but not much is known about representation of these groups in randomized controlled trials (RCTs). We explored temporal trends in and RCT factors associated with the reporting of race and ethnicity data and the enrollment of BIPOC in heart failure RCTs. Methods: We searched MEDLINE, EMBASE, and CINAHL for heart failure RCTs published in journals with an impact factor ≥10 between January 1, 2000 and June 17, 2020. We used the Cochran-Armitage and Jonchkeere-Terpstra tests to examine temporal trends, and multivariable regression to assess the association between trial characteristics and outcomes. Results: Of 414 RCTs meeting inclusion criteria, only 157 (37.9% [95% CI, 33.2%–2.8%]) reported race and ethnicity data. Among 158 200 participants in these 157 RCTs, 29 512 (18.7% [95% CI, 18.5%–18.9%]) were BIPOC. There was a temporal increase in reporting of race and ethnicity data (29.5% in 2000–2003 to 54.7% in 2016–2020, P <0.001) and in enrollment of BIPOC (14.4% in 2000–2003 to 22.2% in 2016–2020, P =0.038). Trial leadership by a woman was independently associated with twice the odds of reporting race and ethnicity data (odds ratio, 2.0 [95% CI, 1.1–3.8]; P =0.028) and an 8.4% increase (95% CI, 1.9%–15.0%; P =0.013) in BIPOC enrollment. Conclusions: A minority of heart failure RCTs reported race and ethnicity data, and among these, BIPOC were under-enrolled relative to disease distribution. Both reporting of race and ethnicity as well as enrollment of BIPOC increased between 2000 and 2020. After multivariable adjustment, trials led by women had greater odds of reporting race and ethnicity and enrolling BIPOC.
