Reduced protocol compliance was the most frequently identified modifiable predictive factor for adverse LOS , morbidity and readmission .
Conclusion Protocol compliance is the most frequently reported predictive factor for outcomes of ERAS programmes following laparoscopic colorectal resection .
Reduced compliance increases LOS , morbidity and readmission to hospital .
The impact of compliance with individual ERAS protocol elements is insufficiently studied , and the lack of a st and ardised framework for evaluating ERAS programmes makes it difficult to draw definite conclusions about which factors exert the greatest impact on outcome after laparoscopic colorectal resection
Objective To perform a systematic review of published literature for the factors reported to predict outcomes of enhanced recovery after surgery ( ERAS ) programmes following  laparoscopic colorectal surgery .
Background ERAS programmes and the use of laparoscopy have been widely adopted in colorectal surgery bringing short-term patient benefit .
However , there is a minority of patients that do not benefit from these strategies and their identification is not well characterised .
The factors that underpin outcomes from ERAS programmes for laparoscopic patients are not understood .
Randomized clinical trial of multimodal optimization of surgical care in patients undergoing major colonic resection
The aim of this trial was to compare  multimodal optimization  with  conventional perioperative management  in a consecutive series of patients undergoing a wide range of colorectal procedures
