背景：有效的機構基礎設施被認為是成功導入和持續發展實證護理的重要因素。臺灣雖已推動實證護理長達十年，然而各機構間推動實證護理的政策與執行策略卻仍有差異，也面臨許多在機構基礎設施面上的困難；因此需要建立以基礎設施為焦點的實證護理推動模式。目的：本研究旨在確認推動實證護理必備的機構基礎設施，以建立一個能於醫院情境中有效導入實證護理的推動模式。方法：本研究先以專家小組討論的方式擬定模式初稿，再利用德爾菲（Delphi）調查法建立對此模式之共識，總共有30名專家參加三回合的德爾菲調查，最後再由10位具有推動實證護理或實證醫學經驗的專家進行焦點團體座談，以讓本模式能實際應用於醫院情境。結果：本研究所建構之實證護理推動模式包含五大構面和相關的策略，包含設備（equipment）、政策（policy）、訓練課程（training courses）、成果指標（outcome indicators）和獎勵計畫（reward plans）等，因此本模式命名為EPCOR模式。結論／應用：EPCOR模式說明在臺灣特別是於醫院內推動實證護理時所必備的機構基礎設施以及相關的策略。醫院可以應用EPCOR模式來啟動、實施、和評值推動實證護理的成效。

Background: An effective organizational infrastructure is essential to successfully implement and sustain an evidence-based nursing (EBN) practice. Although EBN has been promoted in Taiwan for more than 10 years, variations in the organizational policies and strategies necessary to support EBN among healthcare organizations have prevented effective implementation. Barriers to the implementation of EBN located at the organizational level have also been reported. The need for a model that focuses on the organizational infrastructure to promote EBN in Taiwan has therefore become increasingly apparent. Purpose: This study aims to develop a model that contains the key contextual elements of organizational infrastructure necessary to effectively promote EBN, especially in hospital settings. Methods: A steering committee drafted the components and related strategies of the proposedmodel. Delphi techniquewas used to obtain consensus on the proposed model among a group of experts with expertise in EBN. Thirty experts participated in all three rounds of the Delphi survey. To confirm the appropriateness of the proposed model for clinical settings, the model was further reviewed by a focus group composed of experts with experience in implementing EBN or evidence-based medicine in hospitals. The strategies were then further modified based on the suggestions of this focus group, and only those strategies that best fit hospital settings were retained. Results: Five key contextual elements and related strategic processes were identified, including equipment, policy, training courses, outcome indicators, and reward plans. The resultant model was named EPCOR, an acronym composed of the names of each identified element. Conclusions/Implications for Practice: EPCOR is a comprehensive model of organizational infrastructure and strategic procedures for implementing EBN in hospital-based settings in Taiwan. Organizations may use the EPCOR model to initiate and implement EBN practices and then to evaluate their effectiveness.
