Colectomy rates for ulcerative colitis in England 2003-2016

Area of Science:

• Gastroenterology
• Surgical Outcomes
• Health Services Research

Background:

• Temporal trends in colectomy for ulcerative colitis (UC) are crucial given evolving standards in inflammatory bowel disease (IBD) management.
• Changing approaches to the salvage of acute severe UC necessitate updated analyses of colectomy rates.

Purpose of the Study:

• To investigate temporal trends in colectomy rates for ulcerative colitis (UC) in England.
• To analyze colectomy rates in both emergency and total population cohorts undergoing UC treatment.

Main Methods:

• Utilized English Hospital Episode Statistics (HES) data from 2003-2016.
• Analyzed two cohorts: 'emergency' (UC admission ≥3 days, age ≥18) and 'total population' (all UC colectomies).
• Employed interrupted time series (ITS) analysis and mixed methods.

Main Results:

• Short-term (30, 90-day) colectomy rates after emergency UC admission decreased by 4% annually post-2008, but this trend did not persist beyond one year.
• Total and elective colectomy rates for UC showed a 3.1% annual reduction post-2008, while emergency colectomy rates remained unchanged.
• Mortality and laparoscopy rates improved with non-colectomy management, but emergency colectomies after initial salvage increased.

Conclusions:

• Observed reductions in short-term colectomy rates for UC do not extend beyond one year.
• Emergency colectomy rates for UC have not significantly changed, indicating a persistent need for timely surgical intervention.
• Improvements in IBD care likely contribute to reduced rates, but data limitations on disease severity hinder further interpretation of salvage and surgical timing.
