Creating a world where no patients are harmed by diagnostic error.

SIDM catalyzes and leads change to improve diagnosis and eliminate harm from diagnostic error, in partnership with patients, their families, the healthcare community and every interested stakeholder.


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.

1 in 3

One-third of malpractice cases that result in death or permanent disability stem from an inaccurate or delayed diagnosis, making it the number one cause of serious harms among medical errors.

*Research published in Diagnosis


Diagnostic errors affect an estimated 12 million Americans each year, and likely cause more harm to patients than all other medical errors combined.

*Research published in BMJ Quality & Safety

Roughly 40,000‐80,000 deaths in U.S. hospitals each year can be attributed to diagnostic error. It’s about the same number of people who die annually from breast cancer or diabetes.

Programs & Initiatives

Testing Interventions

Inaccurate or delayed diagnosis is the most common, catastrophic, and costly type of medical error. Through the DxQI Seed Grant Program, SIDM will award grants to support specific quality improvement work directed towards improving diagnosis.

Collaborating to Improve Diagnosis

The Coalition to Improve Diagnosis is comprised of 60+ healthcare organizations working to find solutions that enhance diagnostic quality and safety, reduce harm and ultimately, ensure better health outcomes for patients.

Diagnosis and Telemedicine

The COVID-19 pandemic has transformed the usage of telemedicine overnight, establishing it as a mainstay for healthcare delivery and diagnosis. To navigate this new era of “telediagnosis,” SIDM will convened a series of conversations about TeleDx research priorities.
