Collective Intelligence of Peer Learning: Promoting Culture of Learning and Improvement Among Radiologists

The traditional Scoring-Based Peer Review system has been the predominant radiology performance quality assurance model, which can become a condemning, ineffective process. In 2015, the Institute of Medicine called for "policies and practices that promote a non-punitive culture that values open discussion and feedback on diagnostic performance." The development of Peer Learning (PL), a process that encompasses peer feedback, learning, and improvement, has positively impacted radiology through the recognition of success, identification of mistakes as learning opportunities, and development of a professional culture of trust. Furthermore, collective intelligence advances the PL process within the learning community, optimizing the abilities of a group effort that outperform that of a single individual, especially in the setting of complex medical and diagnostic imaging decision-making. The objective of the review article is to highlight the collective intelligence aspect of PL program, which allows PL to be more effective than established peer review model.
