Abstract
INTRODUCTION: Patients undergoing emergency colorectal cancer (CRC) surgery are at higher risk of poor outcome than those managed electively. The aim of this national study is to identify groups at high risk of undergoing unplanned CRC surgery and assess short and long-term outcome in this cohort subsequent morbidity and mortality as well as quantify their long-term survival.
METHODS: The Hospital Episode Statistics (HES) database between the years of 1997-2012 was used to identify all patients that had undergone surgery for colorectal cancer. Multivariable logistic regression analysis and cox regression analyses were undertaken to identify patient factors predictive of undergoing emergency and quantify their long-term survival.
RESULTS: A total of 286,591 patients underwent resection for CRC between April 1997 and April 2012, of which 24.3% (69,718 patients) were admitted as emergencies underwent emergency surgery. Independent predictors of undergoing emergency surgery were female gender (OR 1.23, CI: 1.21-1.25, p < 0.001), older age (>79 years old OR 1.55, CI: 1.50-1.60, p < 0.001), social deprivation (most deprived quintile, OR 1.64, CI: 1.50-1.80, p < 0.001) and Black African/Caribbean ethnicity (OR 1.36, CI: 1.21-1.66, p < 0.001). All cause 30- and 90-day mortality within the emergency group was significantly higher than that for the electively managed patients group (13.3% versus compared with 3.4% at 30-days) as was 90-day (20.0% versus compared with 5.8% at 90-days). Amongst patients eligible for bowel screening there was an approximate 40% significant reduction in the proportion of patients requiring emergency surgery before and after its introduction bowel screening in 2006 (23.4%-14.9%, p < 0.001). This reduction in emergency surgery included both proximal and distal cancer resections.
CONCLUSION: Older, socially deprived and ethnic minority patients with colorectal cancer are more likely to present as emergencies requiring CRC surgery. Public health initiatives, such as bowel cancer screening, appear to have concomitantly reduced emergency and increased elective surgical rates within the eligible cohort. This is likely to have a beneficial impact on population survival aimed at preventing emergency presentation by identifying patients at specific risk could improve survival outcome for colorectal cancer surgery in England.
