Introduction: Fine art education increases the quality and quantity of observations that medical students make in both art and clinical reports. However, there are few free and accessible resources that teach art and observational skills to healthcare learners and providers. CanadiEM.org, a medical education blog, developed a new series called Spot the Diagnosis! to address this gap. The goals of the Spot the Diagnosis! series are to: 1) use art to explain medical concepts, 2) tie medical concepts to visual art, 3) hone observational skills, and 4) expose healthcare providers to art. Methods: Each piece of art for the Spot the Diagnosis! Series is selected based upon the author’s art history knowledge, resources found using an online search, and/or suggestions made by other healthcare professionals. The accompanying blog post is researched and written by a medical student in a question-and-answer style and peer-reviewed by another medical student and physician. Posts are uploaded monthly to CanadiEM.org and accessible to anyone with an internet connection. Promotion occurs on site, via email, word-of-mouth, and social media. Viewership is tracked using Google Analytics (GA). A survey for readers is planned to assess who, how, and why readers use the series, but results were not available prior to abstract submission. Results: Six Spot the Diagnosis! posts have been published, each of which begins with the selection of a piece of fine arts that showcases a potential medical diagnosis and a blog post outlining an interpretation of the work informed by observations, historical reports, and medical evidence. Each was published as a blog post on a Saturday and added to a page containing a list of all posts in the broader Arts PRN section on CanadiEM. All contained a single piece of art as the focus, 6 ± 2 (median ± IQR) questions, 638 ± 250 words, and 6 ± 3 references. The answers to questions are hidden under drop-down formatting to allow viewers to arrive at their own answers first. In the first 30 days of publication, each post in the series was viewed 1582 ± 401 times. Conclusion: The Spot the Diagnosis! series is an online educational resource published on CanadiEM.org that aims to improve learners medical knowledge and observational skills by featuring fine arts pieces with relevant question-and-answer style posts. This series fills the gap between art and medicine and has been well received by CanadiEM viewers. We look forward to analyzing responses in our survey to further understand how, why, and who uses this new and innovative resource.
