Summary

Diagnostic error is a major safety risk in hospitals. This Swiss study of general medical inpatients—a group rarely examined because more science is available on high-risk subgroups—found errors were common and often harmful. They frequently resulted from not considering the correct diagnosis, not ordering appropriate tests, or missing key physical exam findings.
