The Lens: Can a Weekly Newsletter Improve Medical Student Knowledge of the Ophthalmology Literature?

Medical trainees often report barriers to their active engagement with academic medical literature. We assessed whether subscription to The Lens, a weekly newsletter summarizing recent ophthalmology literature, improved readers' knowledge of the literature. The implementation, uptake, and feasibility of The Lens are described. To assess newsletter efficacy, a 14 question multiple-choice quiz was designed with seven questions based on research articles featured in The Lens and seven based on articles published in high impact ophthalmology journals that were not featured in The Lens. The quiz was statistically validated in a sub-sample of non-subscribers to confirm similar difficulty between Lens and non-Lens quiz items. Among subscribers, within-participant scores on each subsection were compared using paired t-tests. Linear regression was used to determine if participation-adjusted subscription length was associated with quiz scores, after covariate adjustment. Medical student subscribers of The Lens. Over 12 months, The Lens attained 352 subscribers and summarized 410 research articles in 40 newsletters, at a monetary cost of <$5 per issue. The survey sample comprises 59 medical students who subscribed to The Lens. Subjectively, 83.1% of subscribers reported that The Lens helped them learn about the ophthalmology literature. Among non-subscribers, scores on the Lens and non-Lens quiz subsections were similar (median paired difference = 0%), indicating that subsections were similar in difficulty. Lens subscribers correctly answered 51.1% of Lens items, compared to 42.9% of non-Lens items (mean paired difference, 8.2%; p=0.022), indicating that readers retained information presented in The Lens. In an adjusted linear regression model, each additional participation-adjusted month of subscription to The Lens was associated with a 2.7% improvement in Lens item quiz score (p=0.022). Weekly newsletters can help trainees across medical specialties overcome barriers to engagement with the academic literature and improve their knowledge of recently published studies.
