Background: Financial incentives are effective in moderating physician and patient behaviour, but they have not been studied in the context of medical education.
Aim: This study assessed whether financial incentives can motivate students to acquire electrocardiogram (ECG) interpretation skills.
Methods: Students enrolled for a cardio-respiratory teaching module (n = 121) were randomised to an intervention (financial incentive) or a control (book voucher raffle) condition. All students took three validated exams of ECG interpretation skills (at module entry, module exit and seven weeks later). Only the exit exam was financially incentivised in the intervention group. The primary outcome was the proportion of students who correctly identified ≥60% of clinically important diagnoses in the exit exam.
Results: Financial incentives more than doubled the odds of correctly identifying ≥60% of diagnoses in the exit exam (adjusted odds ratio 2.44, 95% confidence interval 1.05-5.67) and significantly increased student learning time. However, there was no significant effect on performance levels in the retention exam.
Conclusions: Financial incentives increase reported learning time and examination results in the short-term. The lack of a sustained effect on performance suggests that financial incentives may foster a superficial or strategic rather than a deep approach to learning.
