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 .
Enhanced Recovery Program following Colorectal Resection in the Elderly Patient
Background The enhanced recovery program ( ERP ) aims to reduce the metabolic response to surgery , hastening recovery and shortening hospital stay . Concerns exist regarding morbidity and hospital stay in elderly patients . The present study aim ed to compare the outcomes and compliance of elderly patients managed by an ERP protocol with a younger group . Methods A review was performed of a prospect i ve data base of patients undergoing colorectal resection managed under the ERP protocol between 2005 and 2010 . Patients were grouped into < 80 years and ≥80 years , and perioperative data were collated . The postoperative outcomes were compared with the goals set out by the ERP protocol . Results A total of 688 patients were included , 558 were < 80 years ( median : 66 years ; range : 17–79 years ) and 130 were ≥80 years ( median : 83 years ; range : 80–95 years ) . Some 96 % of operations were planned laparoscopically . Median total length of hospital stay was 6 days ( range : 1–108 days ) for the < 80 year group and 8 days ( range : 1–167 days ; P 0.363 ) for the elderly group , with a 30 day readmission rate of 8.6 % for the population and no significant differences between groups . The 30 day mortality was 5 % , with a significant difference between the two groups ( P < 0.0001 ) . Differences in protocol adherence were identified in the discontinuation of intravenous fluids , catheter removal , and early mobilization . Conclusions An enhanced recovery program is feasible for colorectal surgery patients ≥80 years of age , with similar compliance as the younger group to some aspects of the protocol and an acceptable readmission rate . Attention to improving compliance in the postoperative phase is necessary , particularly in such high-risk patients , as such improvement may reduce the morbidity and mortality
