Numerous professional bodies have questioned whether traditional input-based continuing professional development (CPD) schemes are effective at measuring genuine learning and improving practice performance and patient health. The most commonly used type of long-established CPD activities, such as conferences, lectures and symposia, have been found to have a limited effect on improving practitioner competence and performance, and no significant effect on patient health outcomes. Additionally, it is thought that the impact of many CPD activities is reduced when they are undertaken in isolation outside of a defined structure of directed learning. In contrast, CPD activities which are interactive, encourage reflection on practice, provide opportunities to practice skills, involve multiple exposures, help practitioners to identify between current performance and a standard to be achieved, and are focused on outcomes, are the most effective at improving practice and patient health outcomes.
