背景 「三讀五對」及給藥過程被干擾是導致護理人員給藥錯誤的最常見原因。
目的 探討線上「三讀五對」與「給藥過程干擾處理」的給藥客觀結構式影像測試（objective structured video examinations, OSVE）介入於提升護理人員給藥自我效能與辨認給藥錯誤行為之成效。
方法 採類實驗前測、後測研究設計，以同伴推動抽樣法共招募112位護理人員參與本線上研究。研究工具包括給藥自我效能問卷、四個給藥錯誤行為OSVE及其對應之辨認給藥錯誤行為問題，介入措施為一個正確給藥行為OSVE。成對樣本t檢定用以分析二個變項在前測與後測的差異。
結果 112位研究樣本的平均年齡為27.21歲，平均工作年資為4.67年，給藥自我效能於前測得分為38.88（SD = 4.45），後測得分為 41.69（SD = 4.58），二者達顯著差異（t = 7.11, p < .001）；辨認給藥錯誤行為前測得分為10.71（SD = 7.16 )，後測得分為15.32（ SD = 4.94），二者也呈顯著差異（t = 5.90, p < .001）。
結論／實務應用 線上給藥OSVE可立即提升臨床護理人員辨認給藥錯誤行為的正確性，並提高自我效能，未來研究需探討其在提升實際給藥安全的成效。

Background: Failure to follow the “Five Rights” and interruptions during medication administration are the two most common factors underlying nurse-related medication errors.
Purpose: This study was designed to examine the effectiveness in terms of improving nurses’ medication administration self-efficacy and recognition of medication errors of an online objective structured video examination (OSVE) intervention focused on the “Five Rights” and “management of interruptions during medication administration”.
Methods: A quasi-experimental pretest-posttest research design with a respondent-driven sampling method was employed. One hundred and twelve nurses finished the online survey. Instruments included the self-efficacy of medication administration questionnaire and four online medication error OSVEs addressing the issue of medication error recognition. The intervention was an acute medication behavior OSVE. Paired t-tests were used to assess the pre-test / post-test differences between variables.
Results: The mean age of the 112 survey respondents was 27.21 years, and the mean years of working experience was 4.67. The mean self-efficacy of medication administration score, which was 38.88 (SD = 4.45) at baseline, increased significantly to 41.69 (SD = 4.58) at post-test (t = 7.11, p < .001). Similarly, the mean score for recognition of medication errors was 10.71 (SD = 7.16) at pre-test and significantly higher (15.32; SD = 4.94) at post-test (t = 5.90, p < .001).
Conclusions/Implications for Practice: The online OSVE may be used to improve the recognition of medication errors and self-efficacy of medication administration in nurses. Future research is needed to examine the effect of this intervention in enhancing the safety of medication administration in actual clinical practice settings.
