A near miss in healthcare is an error, hazard or unsafe event that could have harmed a patient but did not, either because it was detected in time or because chance prevented injury.
Near misses are valuable because they reveal weak points in a system before those weaknesses produce actual harm.
A Near Miss Is Not “Nothing Happened”
The absence of injury does not mean the underlying risk was unimportant. If the same conditions remain, a future patient may not be as fortunate.
Near Misses Can Occur Anywhere
Examples include an incorrect medicine intercepted before administration, a wrong-patient specimen identified before testing, or a critical result noticed just before discharge.
Near Misses Differ From Medical Errors
A medical error describes the failed action or plan. A near miss describes the outcome state in which that error or hazard did not reach the patient or did not cause harm.
Reporting Creates Learning
When near misses are captured, healthcare systems can examine workflow, communication, equipment, labelling and responsibility before a more serious event occurs.
Patient Safety Uses Near Misses as Early Warning Signals
They can identify system vulnerabilities that ordinary outcome statistics miss because no injury occurred.
The Near-Miss Loop
hazard or error → interception before harm → report → analyse contributing factors → strengthen safeguard → monitor recurrence.
Educational boundary: This article explains near misses conceptually. Actual safety events should be handled through the appropriate healthcare organisation and professional processes.
