Description of intervention(s) / exposure
A quality improvement program for all patients undergoing colorectal resections at the Karolinska University Hospital (Section of coloproctology). The program contains three key elements and was implemented in January 2010. The post implementation study period was January 2010-December 2013.
1. Exclusion of nonsteroidal anti-inflammatory drugs peri-operatively from 5 days before surgery to 7 days after surgery..
2. Introduction of intra-operative goal-directed fluid therapy. This was managed by stroke volume optimization using esphageal Doppler (CardioQ-ODM, Deltex Medical, Chichester, UK).
3. Avoidance of primary anastomoses in emergency resections. Surgeons were instructed to avoid emergency oncological resections of obstructing cancers by instead performing temporary defunctioning ostomies or avoid primary anastomosis if emergency resection was unavoidable (i.e. bowel perforation or severe bleeding).

Not applicable
Comparator / control treatment
The control group is the cohort of patients that were operated with colorectal resections at the Karolinska University Hospital (Section of coloproctology) during the last four years before the implementation of the quality improvement program i.e. January 2006-December 2009.

Outcomes
Primary outcome [1] 303218 0
Primary endpoint is the proportion of patients developing anastomotic leakage after colorectal resections with primary anastomosis.
Timepoint [1] 303218 0
Primary endpoint is anastomotic leakage detected at re-operation or by CT-scan with rectal contrast within 30 days post operatively. Data are recorded prospectively by a research nurse and put in to a local quality data base..
Secondary outcome [1] 338263 0
Postoperative length of stay in hospital (days).
Timepoint [1] 338263 0
At hospital discharge

Statistical methods / analysis
Power calculation shows that with a power of 80% for the detection of a decrease in anastomotic leakage rate from 10% to 5% the number of participants in each group must be at least 435. The study period is set accordingly. The assumption is based on data from our local quality data base and other similar studies.
Groups are compared with non-parametric tests and Fisher’s exact tests. Univariable logistic regression is used to assess the crude effect of study period and other predictors on anastomotic leakage. Potential confounders are assessed with multivariable logistic regression analysis.
