背景：行動護理站是結合無線網路、資訊科技設備及線上記錄的新型護理工作車，除提高臨床工作效率及簡化作業流程，並透過各系統資料串連和設備的相輔相成，可提供護理人員執行照護的作業標準外，另可減少重覆書寫的時間，以增加病人的直接護理時間，與促進病人安全。目的：本研究目的乃在探討護理人員使用行動護理站的成效，比較護理活動取樣之工作內容分布是否不同，及使用護理資訊系統介面可用性的評值結果。方法本研究方法有兩部份，一為透過工作取樣觀察法，進行有使用行動護理站的病房（行動組n = 18）與未使用之病房護理人員（傳統組n = 14），分別進行護理活動內容之資料收集；另外，針對行動組病房及曾支援該病房而使用過護理站的護理人員（n = 30），以護理資訊系統介面可用性調查表，探討護理人員對其介面可用性程度及使用成效。結果：本研究結果顯示使用行動護理站護理資訊系統會增加護理工作中之直接護理活動，且降低間接護理活動與護理紀錄之內容分布。另外，問卷調查結果顯示護理人員對其介面可用性及使用成效均趨於正向的評價，但也在開放性問題中呈現硬體設備、網路速度及列印等問題之建議。結論：本研究顯示使用過行動護理站的病房，確實有改變護理的照護行為分布，也呈現護理人員對介面可用性及使用成效趨於正向態度，故行動護理站之使用及其研究對臨床照護有其重要性。

Background: A mobile nursing station is an innovative cart that integrates a wireless network, information technology devices, and online charts. In addition to improving clinical work and workflow efficiencies, data is integrated among different information systems and hardware devices to promote patient safety.Purpose: This study investigated the effectiveness of mobile nursing cart use. We compared different distributions of nursing activity working samples to evaluate the nursing information systems in terms of interface usability and usage outcomes.Methods: There were two parts of this study. Part one used work sampling to collect nursing activity data necessary to compare a unit that used a mobile nursing cart (mobile group, n = 18) with another that did not (traditional group, n = 14). Part two applied a nursing information system interface usability questionnaire to survey the mobile unit with nurses who had used a mobile nursing station (including those who had worked in this unit as floating nurses) (n = 30) in order to explore interface usability and effectiveness.Results: We found that using the mobile nursing station information system increased time spent on direct patient care and decreased time spent on indirect patient care and documentation. Results further indicated that participants rated interface usability as high and evaluated usage effectiveness positively. Comments made in the open-ended question section raised several points of concern, including problems / inadequacies related to hardware devices, Internet speed, and printing.Conclusion: This study indicates that using mobile nursing station can improve nursing activity distributions and that nurses hold generally positive attitudes toward mobile nursing station interface usability and usage effectiveness. The authors thus encourage the continued implementation of mobile nursing stations and related studies to further enhance clinical nursing care.
