Diagnosis, the Journal

Diagnosis is the official peer-reviewed journal of the Society to Improve Diagnosis in Medicine (SIDM). Published by De Gruyter, Diagnosis focuses on how diagnosis can be advanced, how it is taught, and how and why it can fail, leading to diagnostic errors.

Diagnosis JournalThe journal welcomes both fundamental and applied works, improvement initiatives, opinions, and debates to encourage new thinking on improving this critical aspect of healthcare quality.
