The number of patients with a prolonged length of hospital stay i.e. more than 14 days decreased from 27% (n=17) in 2010-2011 to 13% (n=10) in 2012-2013 and 6% (n=5) in 2014-2015 (OR 0.1, 95% CI 0.01-0.97, p=0.047 and OR 0.2, 95% CI 0.1-0.5, p=0.001), with readmission rates of 3% (n=2), 8 % (n=6) and 8% (n=7) respectively. Thirty-day mortality was 3% (n=2), 1% (n=1) and 2% (n=2). Multivariate logistic analysis was not deemed suitable because of the low number of events in each cohort.

Discussion
A comprehensive multidisciplinary care program was implemented in a single teaching hospital as a quality program aimed to improve the outcome of surgery for all elderly colorectal cancer patients. In this study, we assessed the merits of this program by comparing a cohort of patients operated after the introduction of the program with two historical cohorts. Contrary to what we expected, we
