The conceptualization of ‘Key Evidence Leaders’ from ‘Opinion Leaders’: A review also applicable in ophthalmology

The collaboration of ophthalmologists with the industry, in their role as opinion leaders (OLs) who interpret, modify, and disseminate information to professional networks, is susceptible to bias. This review explores the critical role of OLs in the healthcare industry and their evolution into Key Evidence Leaders (KELs), emphasizing the importance of differentiating KELs from traditional OLs to promote evidence-based practices and maintain research integrity in healthcare. OLs often rely on their reputation and experience, which can make them susceptible to industry biases, particularly when financial incentives are involved. The concept of KELs marks a significant evolution from traditional OLs. Unlike OLs, KELs base their influence on expertise in clinical evidence and research, rather than personal experience or industry affiliations. KELs possess strong analytical skills, engage in interdisciplinary collaboration, and emphasize transparency and unbiased dissemination of information. The emergence of KELs represents a significant shift towards evidence-based leadership in healthcare. Differentiating KELs from traditional OLs is crucial for ensuring that the messages received by healthcare professionals are less biased. By supporting KELs who prioritize patient-centered evidence, the industry can enhance trust in the application of medical devices and drugs.
