The Coalition to Improve Diagnosis

The Coalition to Improve Diagnosis, made up of leading healthcare organizations, has been established to bring awareness, attention, and action to the problem of diagnostic error.

Why We Exist

Diagnosis, which by its very nature involves uncertainty, is one of the most difficult and complex tasks in healthcare, involving both human and systematic elements, and is made more difficult by an explosive growth in knowledge and tools that are both helpful and problematic. Errors in diagnosis effect one in 20 patients annually, an estimated 12 million Americans each year. “Physicians excel at diagnosis, but errors or delays in reaching the right diagnosis still create harm, and we can do better,” says Mark L. Graber, MD, FACP, president and founder of the Society to Improve Diagnosis in Medicine.

What We Do

The first job of the Coalition is to bring much-needed attention to the issue of improving diagnosis. “It is an essential step in improving the quality of care patients receive and in reducing harm that can result from diagnoses that are inaccurate, missed or inappropriately delayed.” says Paul Epner, MBA, MEd, chair of the Coalition and executive vice president of the Society to Improve Diagnosis in Medicine.

Organizational members have committed to take measurable action to improve diagnosis through the collective actions of the Coalition as well as opportunities available to and led by each member organization.
