IntroductionCardiac rehabilitation (CR) is strongly indicated in patients with acute myocardial infarction (MI), and has been proven to reduce mortality and recurrence and improve patients quality of life. Although clinical guidelines for CR have already been developed domestically and internationally, hospital-based CR remains underutilized. Currently, studies exploring strategies to improve CR participation in South Korea and Asia are limited.ObjectivesThis study aims to compare the effect of providing CR financial incentives to post-MI patients referred for outpatient CR and to confirm the effect of increasing CR participation and completion rates.MethodsThis single-blind, pragmatic, randomized controlled trial will be conducted at 2 tertiary hospitals for CR after acute MI. The control and experimental groups will be randomized, with each group consisting of 24 participants (total of 48 participants) assigned in a 1:1 ratio. The experimental group will receive 4, 7, and 11 USD per completed session of CR during the 1st to 12th, 13 to 24th, and 25th to 36th sessions of CR, respectively, for 3 months after enrollment. Participants who completed the 36 sessions will receive 260 USD incentives. The primary outcomes at 3 months will be used to assess the CR participation rate, as the number of CR sessions completed, and CR completion, as attendance of sessions greater than 50%, thus completion of ≥18 sessions. The outcomes will be used to compare changes in cardiorespiratory function (VO2 max, VO2 at anabolic threshold), the Korean activity scale index, EuroQol 5 dimensions, and the patient health questionnaire at 3 months after discharge and 6 and 12 months after baseline.DiscussionProviding financial incentives may confirm the effect of increasing CR on participation and completion rates.Copyright © 2023 the Author(s).
