Using real-time device-based visual feedback in CPR recertification programs: A prospective randomised controlled study.

Background: Receiving regular training to maintain CPR skills is critical for in-service health-care professionals, especially because motor skills diminish over time.

Objectives: To compare the effects of real-time device-based visual feedback and conventional instructor-based feedback on the chest compression skills and self-efficacy of nurses receiving a CPR recertification program.

Design: A prospective randomised controlled study with repeated measurements was conducted according to the CONSORT 2010 guidelines.
