A Systematic Review of Clinical Practice Guidelines and Consensus Statements for Cardiac Rehabilitation Delivery: Consensus, Divergence, and Important Knowledge Gaps.

ABSTRACT

BACKGROUND: After 2020, clinical practice recommendations have been released to inform cardiac rehabilitation (CR) programs of best practices for post-COVID programming. The objective of this systematic review was to identify and summarize recommendations from clinical practice guidelines (CPGs) and consensus statements for CR delivery postpandemic. METHODS: Five databases (March 2020 through April 2023), grey literature and Web sites of CR international associations were searched. Inclusion criteria were local, national, and international association-endorsed CPGs, and/or position, expert, and scientific statements related to CR delivery (program models, program elements, and core components). Two researchers independently screened the citations for inclusion. The Appraisal of Guidelines for Research and Evaluation (AGREE) II was used for quality assessment. Results were analyzed in accordance with the Synthesis Without Meta-analysis (SWiM) reporting guidelines. RESULTS: Overall, 4890 records were identified; 4 CPGs, 9 position/scientific statements, and 6 expert/Delphi consensus papers were included. All guidelines/statements included information related to program delivery models, with 95% endorsing the use of virtual, hybrid, home-based, and telerehabilitation, especially during the pandemic. Outside of the context of COVID-19, program components including referral, CR indications, CR contraindications, timing, and structure were included in the 4 CPGs and 2 of 15 statements. Recommendations related to CR core components were primarily focused on exercise, with no changes since before the pandemic except for COVID-19 considerations for safety. One guideline was specific to women, and 1 scientific statement to heart failure with preserved ejection fraction. CONCLUSIONS: Although 19 documents were identified, CR delivery in low resource settings and for culturally and linguistically diverse populations require attention. Additionally, few recommendations on nutrition, psychosocial counselling, and patient education were reported.
