不正確的藥量計算為藥物疏失的一部份,其可能會危及病患安全。然目前並無適合評量的工具,因此,本研究發展藥量計算量表,來檢測護理人員的藥量計算能力。藥量計算量表為一結構性問卷,考題來自於臨床實際情境。研究問卷內容包含2部份,第一部份為背景,第二部份為20題藥量計算,分為時間、滴數、濃度及劑量等4個構面。量表品質其信度使用Cronbach’s α係數,建構效度採概念定義、操作定義、鑑定力指數(>0.3或p<0.05)、修正的項目總相關(>0.3)及因素負荷量(>0.3)來檢測。本研究為橫斷式描述性研究,取樣採立意取樣法,共招募3家教學醫院共216位護理人員為研究對象。經由信效度分析後,較多證據支持藥量計算量表不需刪除任何一題,而研究結果顯示護理人員的藥量計算平均分數為77.8±21.0,20題藥量計算4個構面答對率由高至低依序為:劑量(79.7%)、時間(77.7%)、濃度(77.1%)及滴數(76.7%),其中又以滴數對藥量計算的預測力最高,達71.5%,而在背景中,年齡(F(3, 210)=3.86,p<0.05)、教育程度(t(213)= -2.04,p<0.05)及工作年資(F(2, 212)=4.08,p<0.05)在藥量計算能力上有顯著差異,另外,年齡(r= 0.22,p<0.01)及工作年資(r= 0.19,p<0.01)與藥量計算能力達顯著正相關。本研究藥量計算量表是適合評量護理人員藥量計算能力的工具,建議將其加入護理教科書及國家考試之用,而研究結果顯示護理人員在4個構面的藥量計算能力皆不足。

關鍵詞:藥量計算量表、護理人員、藥量計算能力、藥物疏失、病患安全
Inaccurate medication calculations are a part of medication errors, which may cause patient safety in danger. But no suitable tool for assessment at present; therefore, a MCQ
(medication calculation questionnaire) was developed to exam the nurses’ medication calculation skills. MCQ was a structure questionnaire that based on clinical situations and contained 2 parts. The first part was background. The second part was twenty items of medication calculation, which divided into 4 dimensions: timing, drop, concentration, and dose. Quality of MCQ was evaluated by Cronbach’s α coefficient in reliability with conceptual definition, operational definition, Upper minus Lower indices or Discrimination indices(>0.3 or p<0.05), corrected item-total correlation(>0.3), and factor loading (>0.3) in construct validity. The research was a cross-sectional, descriptive study using judgmental sampling. There were 216 nurses recruited totally from three teaching hospitals. After reliability and construct validity analysis, more evidences supported no one item of the MCQ need deleted and the results showed the mean score of MCQ test was 77.8±21.0 and the sequency of the correct rate of 4 dimensions of MCQ was dose(79.7%), timing(77.7%), concentration(77.1%), and drop(76.7%). The drop was the highest predictor within the 4 dimensions of MCQ, which could explained 71.5% of variance. Among the background, a one-way analysis of variance (ANOVA) reached significant difference on age( F(3, 210)=3.86, p<0.05), education(t(213)= -2.04, p<0.05), and nursing experience( F(2, 212)=4.08, p<0.05). Otherwise, age(r= 0.22, p<0.01) and nursing experience(r= 0.19, p<0.01) were positive correlated with medication calculation skills. The MCQ was adequate for assessment of nurses’ medication calculation skills, join the nursing textbook with official exam were suggested, and the results revealed nurses were not enough in 4 dimensions of medication calculation skills.

Key words: MCQ, nurses, medication calculation skills, medication error, patient safety
