Insights
Improving cardiac rehabilitation (CR) referral rates after percutaneous coronary intervention (PCI) is crucial. Educating cardiologists and implementing a formal referral system significantly boosted CR referrals and participation.
Area of Science:
- Cardiology
- Preventive Medicine
- Healthcare Systems Research
Background:
- Cardiac rehabilitation (CR) is underutilized in the US despite its proven benefits.
- Percutaneous coronary intervention (PCI) offers a key opportunity for CR referral.
- Barriers to CR referral after PCI need identification and mitigation.
Purpose of the Study:
- To determine CR referral rates (RR) post-PCI at an academic center.
- To identify barriers to CR referral and assess cardiologist awareness of CR benefits and indications (CRBI).
- To evaluate the impact of physician education and a formal referral system on CR RR and participation rate (PR).
Main Methods:
- Retrospective data collection of patients undergoing PCI.
- Comparison of referral and non-referral groups.
- Physician questionnaires to assess CRBI awareness and referral practices.
- Post-intervention data collection to measure changes in RR and PR.
Main Results:
- Pre-intervention CR referral rate was 17.6%.
- Lack of physician awareness of CRBI and inconsistent referral patterns were identified barriers.
- Post-intervention, CR referral rate increased to 88.96% (OR 37.73, p<0.0001).
- Participation rate increased by 32.8% to 26%; personal cardiologist endorsement improved graduation rates by 35%.
Conclusions:
- Cardiologist awareness of CRBI is key to increasing CR referral rates.
- Provider education and a formal referral system effectively improve CR referral and participation.
- Personal endorsement by cardiologists enhances patient compliance and CR program completion.
Background:
Cardiac rehabilitation (CR) is an effective preventive measure that remains underutilised in the United States. The study aimed to determine the CR referral rate (RR) after percutaneous coronary intervention (PCI) at an academic tertiary care centre, identify barriers to referral, and evaluate awareness of CR benefits and indications (CRBI) among cardiologists. Subsequently, it aimed to evaluate if an intervention consisting of physicians' education about CRBI and implementation of a formal CR referral system could improve RR and consequently participation rate (PR).
Methods:
Data were retrospectively collected for all consecutive patients who underwent PCI over 12 months. Referral rate was determined and variables were compared for differences between referred and non-referred patients. A questionnaire was distributed among the physicians in the Division of Cardiology to assess awareness of CRBI and referral practice patterns. After implementation of the intervention, data were collected retrospectively for consecutive patients who underwent PCI in the following six months. Referral rate and changes in PRs were determined.
Results:
Prior to the intervention, RR was 17.6%. Different barriers were identified, but the questionnaire revealed lack of physicians' awareness of CRBI and inconsistent referral patterns. After the intervention, RR increased to 88.96% (Odds Ratio 37.73, 95% CI 21.34-66.70, p<0.0001) and PR increased by 32.8% to reach 26%. Personal endorsement of CRBI by cardiologists known to patients increased CR program graduation rate by 35%.
Conclusions:
Cardiologists' awareness of CRBI increases CR RR and their personal endorsement improves PR and compliance. Education of providers and implementation of a formal referral system can improve RR and PR.
