Nursing malpractice is often discussed in terms of one bad outcome, but the numbers show a steady pattern of preventable harm tied to real-world care gaps. Every year, 1.1 million preventable patient safety incidents are estimated to occur in U.S. hospitals, and costs keep stacking up across medication events, documentation issues, and unsafe staffing. We break down the statistics that explain why risk is so persistent and why prevention efforts need to target the specific failures that repeatedly surface in claims.
