背景／目的：自2010 年1 月1 日始全國各急診室統一使用新建構的五級檢傷分類電腦化系統進行 病人檢傷分類。本研究目的在探討急診檢傷護理師執行E 化五級檢傷分類系統的分級一致 性及其影響因素。 研究方法：採前瞻性、橫斷式研究法，以收集1 位標竿護理師與14 位急診檢傷護理師個別使用E 化五級檢傷分類系統，同步進行病人檢傷分類的結果。自2012 年8 月至2013 年7 月，共 收集239 位有效樣本。 研究結果：結果發現檢傷護理師與標竿護理師間的一致性“幾乎完全吻合”(weighted kappa= .886)，整體一致性為93.72%。檢傷低估有5.43%，檢傷高估為0.84%。以護理職級來看， 一致性比率最高為N4（95.10%）。 結論：研究結果顯示急診檢傷護理師使用E 化五級檢傷分類系統執行檢傷分類的結果是可信的。 工作年資與護理專業進階能力可作為檢傷一致性因素之考量，期望本研究結果可供各醫療 院所訓練檢傷護理師課程之參考。

Background/Purpose: The five-level electronic triage system(Taiwan Triage and Acuity Scale, TTAS) was implemented over the emergency departments (ED) in Taiwan on January 1, 2010. The purpose of this study was to explore the agreement and affecting factors of five-level triage system among the ED triage nurses. Methods: This study was a prospective design. Data were collected by using one trained research nurse with fourteen ED triage nurses implementing the TTAS simultaneously to determine the triage level in ED patients. From August 2012 to July 2013, a total of 239 effective examples of ED patients were evaluated. Results: The results found that the inter-observer agreement was 93.72% with a weighted kappa of .886 of triage level among the ED triage nurses and the benchmark nurse. The under-triage was 5.43% and over-triage was 0.84%. The highest agreement ratio (95.10%) is the N4 of nursing clinical ladder. Conclusions: The results from this study indicated that the TTAS used by ED triage nurses was reliable. Years of clinical working experience and nursing clinical ladder were the affecting factors of the ED triage nurses’ agreement. The results of this study could serve as a reference for designing training courses for triage nurses.
