Abstract:

Objective To comprehensively evaluate the current status of clinical application of evidence for early enteral nutrition support in ICU prone mechanically ventilated patients and to develop audit indicators，and to analyze the barriers and facilitators，and to formulate strategies for change. Methods Through the evidence summary，16 items of best evidence were included，and 20 audit indicators were developed. Based on the results of the baseline audit of clinical practice，the barriers and facilitators were analyzed，and change strategies were developed. Results Among the 20 indicators reviewed in this study，the clinical implementation rate of only one indicator was 100%，15 indicators were 0，and the range of implementation rates for the other indicators was 8.7%~95.7%. The main barriers were the lack of standardized management procedures，lack of relevant knowledge and training for medical staff，lack of multidisciplinary cooperation. While facilitators were mainly strong leadership of managers，hospitals with rich experience in evidence-based practice and a mature team of specialist nurses，and high level of information technology. Conclusion There is a large gap between the best evidence for early enteral nutrition support for ICU mechanically ventilated patients in the prone position and clinical practice. We should fully utilize the facilitators，overcome the barriers，and implement strategies for change，to promote effective translation of evidence to clinical practice.
