Everyone has a role to play in improving diagnosis. Diagnosis is one of the most complex aspects of healthcare, and sometimes cognition and knowledge limitation are factors in diagnostic errors.

While physicians get it right 90 percent of the time, the one in 10 diagnoses that are missed often have devastating consequences. Understanding the factors that support an accurate and timely diagnosis are key to improving the process.


  • Diagnostic reasoning is fundamental for any provider. The Society to Improve Diagnosis in Medicine’s (SIDM) Clinical Reasoning Toolkit highlights dozens of scholarly articles and resources to improve clinical reasoning skills.
  • For those working in medical education, assessment of clinical reasoning skills is essential as we train the next generation of physicians. The Assessment of Reasoning Tool is a practical resource to support you in evaluating your trainee’s clinical reasoning skills. A series of educational videos will help you understand the process.
  • Getting it Right: Cases to Improve Diagnosis, developed by the American College of Physicians in collaboration with SIDM, encourages practicing clinicians to think about diagnostic decision-making and how errors can be mitigated.
  • Aquifer and SIDM have developed a free virtual patient course, Case-Based Virtual Learning Course: Diagnostic Excellence, which contains foundational content about diagnosis, including factors that contribute to error and strategies that can be used to avoid error.
  • Read The New York Times’ regular column, Diagnosis, where Lisa Sanders, MD, FACP recreates hard-to-solve medical case studies and opens it up to the audience to discuss the diagnosis and tactics to achieve better diagnosis.
