Preventable diagnostic errors remain a significant cause of harm in U.S. hospitals, yet there is a substantial gap in the implementation of evidence-based practices to stop these errors. Two recent articles, "Hospital Commitments to Address Diagnostic Errors" (2024) and " Burden of Serious Harms From Diagnostic Errors in the USA" (2023), underscore the severity of diagnostic failures and highlight the most responsible culprit—hospital leadership.

According to the " Burden of Serious Harms," an estimated 795,000 Americans suffer permanent disability or death annually due to diagnostic errors across various medical settings, including hospitals and outpatient clinics. This places diagnostic errors among the most significant sources of preventable harm in health care, with these mistakes responsible for more serious injuries than many other patient safety issues combined. One troubling revelation is that every patient in the United States is likely to encounter a diagnostic error during their lifetime.
