本專案旨在提升骨外科術後病患自控式止痛使用成效。在資料收集的過程中發現病患對自控式止痛的使用並不了解，導致對PCA之滿意度低；僅48%，同時因護理人員對PCA的熟悉度低只有44%，故無法立即解決PCA所致之問題；再者，又因本院缺乏PCA衛教單張與PCA機器異常警訊處理流程，以致病患對PCA之使用成效不佳，故成立本專案小組，經過專案解決辦法，如完成表單製作、儀器簡易操作及異常處理規範、建立標準作業流程、舉辦在職教育等實施後，結果顯示病患對PCA之滿意度由原來48%提升至92%，而護理人員對PCA之熟悉度亦由原來44%提升至100%，達本專案目的。本專案之實施在臨床工作上不僅有效的改善病患術後疼痛的問題，也縮短護理人員處理PCA發生異常時之時間，進而提升病患滿意度及護理品質。

The aim of this project was to improve the effects of patient-controlled analgesia (PCA) for patients after orthopedic surgery. During data collection, several problems were identified including that patients did not understand how to use PCA after surgery, resulting in a low 48% of patient satisfaction. Moreover, with only 44% nurses familiar with PCA, they could not solve PCA problems immediately. Lack of educational pamphlets, machine errors, and managerial procedures were also identified as problems in this project. Therefore, an improvement team was formed to solve problems. After completing documentation forms, machine manuals, establishing error management standards and standard project procedures, and holding continuing education for nurses, patient understanding of PCA improved from 48% to 92%. Nurses' familiarity with PCA also increased from 44% to 100%. Implementation of this project not only significantly reduced patients' pain after surgery, but also shortened the time for dealing with errors related to PCA use. Finally, patient satisfaction and quality of nursing care were improved.
