ABSTRACT
Objective To explore the best intervention based on evidences of enteral nutrition support complicated with diarrhea in critically ill patients and evaluate its clinical effects.Methods Evidence was obtained using Evidence-based Nursing,and was implemented in clinical practice after localization,we formulated numing recommendations for regulating nurses' clinical practice regarding enteral nutrition support complicated with diarrhea in ICU patients;we conducted multiple online and offline training for nurses.The rate of diarrhea in ICU patients undergoing enteral nutrition support before and after using best evidence was compared,and awareness and implementation of best evidence among nurses before and after training were also compared.Results After adapting the best evidence,the rate of enteral nutrition associated diarrhea decreased from 25.58％ to 13.89％;ICU nurses' diarrhea identification and evaluation,analysis of influencing factors of enteral nutrition associated diarrhea,selection of enteral nutrition formula,nasal feeding,etc.,were significantly improved (P＜0.05);there was no significant difference in enteral nutrition infusion,and nutrition preparation and preservation (P＞0.05);rare of implementation of best evidence in ICU nurses was greater than 80％.Conclusion Evidence-based practice can effectively prevent enteral nutrition associated diarrhea in ICU patients.Nurses can solve enteral nutrition associated diarrhea using scientific nursing methods through implementation of best evidence,in order to nursing quality.
