Eliminating Harm from
Diagnostic Error

The Society to Improve Diagnosis in Medicine (SIDM) is working to create a world where no patients are harmed by diagnostic error.

Understanding Diagnostic Error

Medscape, in partnership with SIDM, developed a learning module for individuals interested in improving diagnostic accuracy.

Webinar: Reducing Harm by Getting Patients the Right Diagnosis at the Right Time

Diagnostic errors are the most common, catastrophic and costly of all medical errors—resulting in thousands of patients suffering serious harm every year.

Watch this SIDM-sponsored Modern Healthcare webinar to learn how to understand diagnostic error, when and where misdiagnoses are most likely to take place, how to track areas for improvement in diagnostic quality, and best practices that systems can employ to improve the diagnostic process.


Patients and family members have a significant opportunity to contribute to diagnostic accuracy and timeliness by actively participating in the diagnostic process. But often, they don't know the questions to ask, the information to offer, or the steps to take to improve diagnosis.

Clinical Teams

Every member of the clinical team has a role to play in ensuring that diagnoses are accurate, timely and communicated to the patient. SIDM offers resources for clinical team members to improve cognitive skills and work within their health systems to improve the diagnostic process.

Medical Educators

Improving diagnosis requires continued investment in medical education, leveraging trainees, practitioners, and educators to address gaps in the system and focus on the teams that contribute to accurate and timely diagnostics. SIDM's resources for medical educators examine clinical reasoning and system factors that underlie diagnostic error, and offer tools and strategies to to bring diagnostic quality and safety into the medical education curriculum.


Whether you're an established researcher or just joining the diagnostic error research community, SIDM offers a variety of resources to help advance research efforts in the field. Explore existing literature, engage with your peers, and join the conversation as we work to foster the growth of the research community.


Despite the fact that diagnostic error likely accounts for more patient harm than all other medical errors combined, federal investment in research to improve diagnosis amounts to about $7 million per year, or just .02% of the total $35 billion federal health research budget. Learn how you can support efforts to expand funding for research.
