Parts of the United States are experiencing record-breaking heat this summer, and yet, icebergs are everywhere! Icebergs—the classic metaphor for situations wherein most of the substance (and risk) hide below the surface—have been used to discuss topics as varied as psychology, homelessness, big data, influence, safety, Hemingway, and school performance. Risks hidden below the surface are prevalent in healthcare, too.

Was the procedure successful within clinical parameters? What was the patient’s out-of-pocket cost? Was the patient readmitted?
