Influences on length of stay in an enhanced recovery programme after colonic surgery.
OBJECTIVE
Enhanced recovery after surgery (ERAS) programmes have been shown to accelerate and enhance functional recovery after colonic surgery. We analysed prospectively collected data to investigate potentially modifiable factors that may influence the length of stay (LOS) in the ERAS setting at a single institution.


METHODS
Between October 2005 and November 2008, prospective data were collected on consecutive patients who underwent elective colonic surgery without a stoma. Patients with rectal cancer, those unable to participate in preoperative ERAS components because of their inability to communicate effectively in English, those with cognitive impairment and those with an American Society of Anesthesiologists (ASA) grade of ≥ 4 were excluded. Statistical analyses were performed using the Mann-Whitney U-test and Cox regression modelling.


RESULTS
A total of 100 (79 malignancies) patients underwent elective colon resection during the study period. There were 57 right-sided, 41 left-sided and two total colectomies. The median age of the patients was 67.5 (range 31-92) years and the median day stay was 4 (range 3-46) days. Factors with significant correlations for reduced LOS were female gender, the surgeon, operative severity, high-dependency unit (HDU) admission and incision type favouring laparoscopic and transverse approaches. Age, operation site, indication for surgery and body mass index were not significant predictors of hospital stay. Gender, operative severity, HDU admission and surgeon did not have any independent correlation with LOS; in contrast to the ASA score and the type of incision, which did.


CONCLUSIONS
Lower ASA score, transverse incision laparotomy and laparoscopy correlated independently with reduced postoperative LOS within the ERAS setting.
