Diagnostic Center of Excellence

The Patient-Partnered Diagnostic Center of Excellence (The Center) was established in October 2022 with a grant from the U.S. Agency for Healthcare Research and Quality (AHRQ).


Our team is working to identify and prevent diagnostic errors in all settings and for every patient. 



Patients, doctors, nurses, research scientists, and other experts in diagnostic safety are partnering together to meet this goal.



We are committed to co-creating solutions to address the needs of patients to improve diagnostic safety.

Patient-Partnered Research in
Diagnostic Safety

    The goal of the Center is to build partnerships to improve diagnosis and diagnostic safety, with a focus on identifying and preventing errors (Safety I) and finding solutions to build resilience for safer care (Safety 2).  Our research is "patient-partnered," meaning that we are working with patients every step of the way, from co-developing research questions to co-designing solutions to the problems that are most important to them. Patient voices are included in everything we do.


    With help from our patient co-investigator, Patient Advisory Committee, and potentially patients like yourself, the Center will co-develop solutions for diagnostic safety improvement in four areas:

Using information reported by patients to identify and learn from diagnostic safety events when they happen. 


Developing a patient-centered taxonomy to classify and describe diagnostic safety issues from the patient perspective, paying special attention to the needs of marginalized patients.


Creating resources and strategies to improve how patients and providers communicate about diagnosis. 


Crafting policies and guidelines around how to equitably engage patients in efforts to improve diagnostic safety.
