Advancing Patient Safety Together

In our October issue of ACT Update, Jeffrey Brady, MD, MPH from the Agency for Healthcare Research and Quality (AHRQ) discusses the National Steering Committee for Patient Safety and their National Action Plan to Advance Patient Safety.

Carmel Crock, MD Awarded Mark L. Graber Diagnostic Quality Award

Congratulations to Carmel Crock, MD on receiving this year’s Mark L. Graber Diagnostic Quality Award for her research, advocacy, and leadership in the field as well as her efforts to expand the field of diagnostic quality & safety internationally.

Annual Report - Improving Diagnosis: Now is the Time

SIDM's mission is to eliminte harm from diagnostic error. The COVID-19 pandemic has not diverted us from that mission; it reaffirms its urgency. Learn more about SIDM's projects and initiatives aimed at improving diagnosic qulaity and safety.

Situativity: Diagnosis in the Real World

Situativity, a group of related theories based in cognitive psychology, offers another way to address diagnostic error by reframing how we understand the cognitive process. Explore ways situativity can impact teaching and improving diagnosis.

SIDM Supports National Action Plan to Advance Patient Safety

The Society to Improve Diagnosis in Medicine (SIDM) joins with the National Steering Committee for Patient Safety (NSC) to announce the release of a National Action Plan intended to provide health systems with renewed momentum and clearer direction for eliminating preventable medical harm.

COVID-19 Testing Is Confusing - What You Need to Know Now

The world’s been turned upside down due to COVID-19. Any virus can be a complicated creature, especially when a new one pops up. And because medical experts are learning as they go, and sharing what they learn with the rest of us, it can sometimes feel like we’re standing on shifting sands as the tide is rising.

New Resources to Address Diagnostic Error

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).

Diagnosis and Telemedicine – What are the Important Research Questions?

The COVID-19 pandemic has transformed the usage of telemedicine overnight, establishing it as a mainstay for healthcare delivery and diagnosis. A new project convened by SIDM, funded by PCORI, will bring together a multi-stakeholder group to make recommendations on the research most needed by the field.

One in 10 Patients with a ‘Big Three’
Disease Misdiagnosed

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.

Coalition Members Respond to COVID-19

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.

Transforming Medical Education

With support from the Josiah Macy Jr. Foundation, SIDM led a three year Consensus Curriculum project to define the key interprofessional competencies required for diagnostic quality and safety.

Collaborating to Improve Diagnosis

The Coalition to Improve Diagnosis is comprised of 50+ healthcare organizations working to find solutions that enhance diagnostic quality and safety, reduce harm and ultimately, ensure better health outcomes for patients.

Closing the Loop on Diagnostic Error

A new collaborative between Constellation and SIDM focuses 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.
