Coalition to Improve Diagnosis

About Our Coalition

The Coalition to Improve Diagnosis, convened and led by the Society to Improve Diagnosis in Medicine (SIDM), is a collaboration of more than 50 leading healthcare organizations focused on ensuring that diagnoses are accurate, communicated and timely. Our Coalition members represent doctors, nurses, testing professionals, patients and their families, employers, researchers, policymakers, educators and leading health organizations and government agencies involved in patient care.

The Coalition to Improve Diagnosis is the only collaboration of diverse healthcare organizations singularly focused on improving the diagnostic process. Together, we work to find solutions that enhance diagnostic quality and safety, reduce harm and ultimately, ensure better health outcomes for patients.

Coalition member organizations support the work of the Coalition on its collective actions in whatever way is appropriate for the member organization. In addition, they commit to engage their organization in ongoing individual meaningful action toward reducing the harm of diagnostic error and improving diagnostic accuracy and timeliness.
