Abstract
BACKGROUND: Temporal trends in colectomy rate for ulcerative colitis (UC) are particularly relevant in the current era of published IBD standards and changing approach to salvage of acute severe disease. AIMS: To investigate temporal trends in colectomy for UC using English population data. METHODS: The Hospital Episode Statistics (HES) were interrogated between 2003-2016 with two patient groups investigated independently. An 'emergency' cohort: emergency UC admission ≥ three days, age ≥18 and a 'total population' cohort: all English patients undergoing colectomy for UC. Mixed methods analyses were utilised. RESULTS: Emergency cohort: 37 981 patients, 49% female, median age 46. The one- and three-year incidence of colectomy after acute admission was 0.17 and 0.21. Interrupted time series (ITS) analysis suggested reductions in colectomy rate of 4% per year after 2008 at 30 and 90 days following emergency admission, with no significant reduction ≥1 year. Mortality and laparoscopy rates improved when avoiding colectomy at index and emergency admissions; however, the proportion of emergency colectomies after salvage at index admission significantly increased during the study period. Total population cohort: 17 580 patients underwent colectomy for UC between 2003 and 2016, demonstrating a 3.1% annual reduction in total and elective colectomies after 2008, but no reduction in emergency colectomies. CONCLUSION: Reductions in short-term colectomy rates after emergency admission for UC do not persist beyond one year. Emergency colectomy rates remain unchanged. Reduced rates are probably due to multi-modal improvements in IBD care. A lack of data regarding disease severity precludes further interpretation of appropriate medical salvage and timely surgery.
