SIDM is excited to announce the 2021 DxQI Seed Grant awardees. These organizations will receive up to $50,000 to test interventions aimed at improving diagnosis.

Safety event reporting is an essential component of any healthcare and hospital system’s efforts to improve patient safety by helping to identify trends and prioritize improvements. While safety event reporting has a long history in health care, its use in the diagnostic space has been considerably more limited and disparately utilized across organizations.

Registration is now open for the Society to Improve Diagnosis in Medicine's (SIDM) Diagnostic Error in Medicine 14th Annual International Conference (SIDM2021), happening virtually October 25-27, 2021. Earn CME/CNE credits while exploring this year's theme, "Reducing Disparities; Improving Diagnosis."

The 2021-2022 Fellowship in Diagnostic Excellence awardees will work on innovative projects focused on improving diagnostic quality and safety.

Read a statement by Paul Epner, CEO of the Society to Improve Diagnosis in Medicine (SIDM) on the Agency for Healthcare Research and Quality’s (AHRQ) recently released Common Formats for Event Reporting - Diagnostic Safety (CFER-DS) Version 0.1.

Recent news stories deliver apparently contradictory messages about AI: future prospects leading to lucrative business deals on the one hand and disappointing performance prompting protests and lawsuits on the other. Expectations remain high that AI will continue to transform many aspects of daily life, including health care. At the same time, AI algorithms have produced results biased against women and people of color, prompting disillusionment and reassessment.

Meet Colorado Hospital Association, MHA Keystone Center and National Association for Healthcare Quality! Learn more about each organization and what they are doing to address diagnostic quality and safety in our latest issue of ACT Update.

Constellation and SIDM have established a Collaborative focused on improving the diagnostic process during two of the three key stages of the diagnostic process: tests and results processing and follow-up and coordination. Clinic, hospital, and health system teams interested in improving the diagnostic process are encouraged to join the Collaborative and access virtual education sessions, webinars, coaching calls, and meetings.

An old joke goes, aging is a question of mind over matter. If you don’t mind, it doesn’t matter. However, it matters very much when aging gets in the way of an accurate diagnosis. Seniors are misdiagnosed more often than younger adults and can be harmed more by it than younger bodies are. Read our latest Dx IQ Column to learn more.

Are you interested in conducting diagnostic comparative effectiveness research (CER), but you don’t know where to start? SIDM's resources and tools can help you translate your issue or topic into a CER question and identify opportunities and methods to co-create your research concept with patient research partners.


SIDM has released two new guides for hospitals and health systems in reducing harm from diagnostic errors, leveraging the lived-experience, insights and expertise of Patient Family Advisory Councils (PFACs).

One in 10 people (9.6%) with symptoms caused by a major vascular event, infection, or cancer will be misdiagnosed, according to a study from researchers at the Johns Hopkins University School of Medicine and CRICO Strategies.

Many of our Coalition to Improve Diagnosis members are on the front lines working diligently to test and diagnose patients during the COVID-19 pandemic. In an effort to provide timely and useful information regarding COVID-19, our members have developed a wide range of resources, including toolkits, live chats, webinars, community groups and more.

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

DxQI Seed Grant Program

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 convene a series of conversations about TeleDx research priorities.

In the News

New Implementation Guide Focuses on Transforming Education of Diagnostic Reasoning

The Society to Improve Diagnosis in Medicine (SIDM) has partnered with the Southern California Permanente Medical Group (SCPMG) and the Human Diagnosis Project (Human Dx) through a grant from the Coverys Foundation to create an education intervention to improve practicing physicians’ diagnostic reasoning.

Conversations with Hospitals, Health Systems & Clinical Practices on Telediagnosis

Although telemedicine has been available for decades, the COVID-19 pandemic has transformed its usage overnight. SIDM is leading an effort to capture and synthesize information about the early successes, the greatest challenges, and the most critical unanswered questions in the use of TeleDx.

DxQI Seed Grant Program

SIDM has established the DxQI Seed Grant Program to engage healthcare organizations in efforts to identify, develop, and test interventions aimed at improving diagnostic quality and reducing harm from diagnostic error.
