材料計價作業錯誤可能造成物料供應短缺，影響臨床作業的順暢，增加護理人員的負擔及醫療成本浪費。本單位經現況分析後發現，骨科材料計價表單異常率為27.3%，骨科手術室護理人員執行材料計價作業正確率為68.9%，故引發專案小組改善動機。本專案目的為提升骨科手術室護理人員材料計價作業正確率達92%。實際解決辦法：建構手術材料計價作業資訊化系統、骨材計價條碼化、自動警示與簡訊提醒功能、舉辦在職教育訓練。專案改善後，手術室護理人員執行骨科材料計價作業正確率由68.9%提升至97.6%，進而使骨科材料計價表單異常率由改善前27.3%下降至3.0%，已達專案目的。期望此專案能提供各醫療院所，推展資訊化作業之參考。

Error of medical materials charging may lead to supply shortage, influence operation process, and increase working load of nursing staff and extra medical costs. Our investigation revealed that the error rate of orthopedic material charging was 27.3%, and the accurate rate for orthopedic perioperative nursing staff to correctly execute material charging process was 68.9%. Thus, the aim of this project was to improve the accuracy of executing charging process up to 92%. The solution was to develop a programmed information system for surgical materials, orthopedic material charging barcodes, automatic alert and short message service (SMS) reminders, and holding continuing education training. After completion of the aforementioned programs, the accuracy rate of correct material charging performed by nursing staffs increased from 68.9% to 97.6%, and the error rate of orthopedic material charging was reduced from 27.3% to 3.0%. Therefore, the goal of our project was achieved. The results may serve as references to facilitate the development of programmed information system at other medical institutes.
