下列何者描述的是「幸運逃脫」（Near miss）事件？

核心概念：醫療錯誤（Medical Error）是指任何本可避免的、導致或可能導致病人傷害的醫療照護行為。這些錯誤可能發生在診斷、治療、用藥、手術等多個環節。「幸運逃脫」（Near Miss）或稱「警示事件」（Sentinel Event precursor），是指一個錯誤已經發生，但由於偶然因素或及時的干預，最終並未造成病人傷害。 為何正確答案對：選項 C 描述「護理師在給藥前攔截了藥物錯誤」。這是一個典型的 Near Miss 事件。錯誤（例如拿錯藥、給錯劑量）已經發生，但由於護理師在執行「五對」原則（Right patient, right drug, right dose, right route, right time）時的警覺性，在藥物進入病人體內造成傷害前被發現並糾正，因此避免了潛在的傷害。 為何其他選項錯： B. 「病人跌倒並骨折」是一個已發生的、造成了病人傷害的醫療不良事件（Adverse Event），而非 Near Miss。 C. 「進行了錯誤的手術」同樣是一個已發生的、嚴重的不良事件，造成了病人重大傷害。 D. 「藥物錯誤導致暫時性病人不適」雖然病人最終恢復，但這已經造成了實際的傷害（Adverse Event），只是傷害程度較輕微，而非 Near Miss。 臨床思路（Patient Safety / Quality Improvement）：識別 Near Miss 事件對於醫療品質的持續改善至關重要。透過分析這些「差點發生」的錯誤，醫療機構可以找出系統性的弱點，並採取預防措施，防止類似錯誤再次發生，進而提升整體病人安全。

Core concept: a medical error is any preventable health care act that causes or could have caused harm to a patient. Such errors may occur in diagnosis, treatment, medication administration, surgery, and many other domains. A 'near miss,' also known as a sentinel event precursor, refers to an error that has occurred but, due to chance or timely intervention, ultimately did not result in patient harm. Why the correct answer is correct: Option C describes the nurse catching a medication error before administration. This is a classic near-miss event. An error (such as a wrong drug or wrong dose) has occurred, but because of the nurse's vigilance in applying the 'five rights' (right patient, right drug, right dose, right route, right time), it was detected and corrected before reaching the patient, thereby averting potential harm. Why the other options are incorrect: B. A patient falling and fracturing a bone is an adverse event that has actually caused harm, not a near miss. C. Performing the wrong surgery is likewise an adverse event that has occurred and caused significant patient harm. D. A medication error causing temporary patient distress, even if the patient eventually recovers, still constitutes an adverse event (with a milder degree of harm), not a near miss. Clinical reasoning (Patient Safety / Quality Improvement): identifying near-miss events is critical to continuous improvement in health care quality. By analyzing 'almost happened' errors, health care organizations can uncover systemic weaknesses and implement preventive measures, thereby improving overall patient safety.

「Near Miss」的概念在美國和台灣的醫療安全與品質管理中均被廣泛應用和強調。美國的醫療機構通常有完善的事件報告系統（如 JCAHO 的要求），鼓勵員工報告 Near Miss 事件，以進行根本原因分析（Root Cause Analysis）並採取預防措施。台灣的醫療機構也逐步建立類似的報告系統和安全文化。此題的核心概念和應用原則在兩地是相同的。
