Objective:To summarize and assess the best evidence of discharge criteria of enhanced recovery for patient after colorectal surgery and to provide reference for clinical practice. Methods:We searched the evidence in domestic and foreign databases to collect litera- tures including clinical decision, guideline(BPG), evidence summary(ES), best practice information sheet(BPIS), recommend practice(RP) and systematic review(SR). The quality of the literature was evaluated and the data were extracted, and the evidence was extracted from the literature that met the quality standards. Results:5 articles were enrolled, including 1 clinical decision, 2 guidelines and 2 evidence sum- mary. Finally 16 items of best evidence were synthesized into 10 categories including time of discharge, tolerance of oral intake, recovery of lower gastrointestinal function, adequate pain control with oral analgesia, ability to mobilize and self-care, clinical examination and labora- tory tests and so on. Conclusions:It is suggested that tolerance of oral intake, recovery of lower gastrointestinal function, adequate pain control with oral analgesia, ability to mobilize and self-care, clinical examination and laboratory tests should be taken as the discharge criteria of patients after colorectal surgery.
