Behavioural insights in the underuse of cardiac resynchronisation therapy in heart failure: a pilot survey on incentive perceptions among referring cardiologists.

AIMS

Heart failure is a leading cause of hospitalisation in patients over 50, significantly impacting both quality of life and survival. Despite the well-established benefits of Cardiac Resynchronisation Therapy (CRT), its utilisation in clinical practice remains suboptimal. Traditional incentives, have shown limited effectiveness in increasing CRT referrals. This manuscript explores how behavioural economics can offer a novel framework for improving CRT uptake by leveraging behavioural incentives, particularly choice architecture and social incentives, to influence physician referral patterns.

METHODS AND RESULTS

We underscore key concepts of behavioural economics, including choice architecture (nudges, reference points, sludges), cognitive biases (status quo bias, overconfidence bias, availability bias), and social incentives, which are applied in designing incentives to promote CRT referrals. A survey was conducted with 51 physicians from six European countries, including electrophysiologists, heart failure specialists, and general cardiologists, recruited through cardiology networks and personal contacts. Participants rated their perceptions of five incentive strategies using a Likert scale (1-5). Behavioural incentives, such as peer comparison through league tables (social incentive) and decision prompts in electronic health records (choice architecture nudge), were perceived as more effective than traditional financial incentives, with a median Likert score of 4.0 [IQR 3.0-5.0] versus 2.5 [IQR 1.5-3.0] for traditional incentives (p < 0.001).

CONCLUSIONS

These findings suggest that interventions drawing on behavioural economics, particularly those utilising social incentives and choice architecture redesign, may offer more effective to increasing CRT referrals than traditional incentives. Such interventions could enhance CRT uptake and outcomes for heart failure patients.
