About the ECR Series

Case-based format

The ECR series utilizes a clinical problem-solving format that allows you to receive and digest information the way it would be received in a real clinical scenario.

Parallel expert commentary

The series includes meta-cognitive commentary from an expert diagnostician. This parallel process allows the reader to understand the framework by which the clinician solves — or doesn’t solve! — the case.

Core concepts explained

We present clinical reasoning concept explanations together with ECR cases highlighting that concept.

Teaching slides

Each case includes downloadable teaching slides with an embedded instructor’s guide.

Community driven

We hope that the ECR website will inspire others to use clinical reasoning concepts to enhance their teaching, and submit their work to the JGIM ECR series.​

Free

All content published on this website is free to use. (But please give us credit if our work is used!)
