Background and Aims: Many patients presenting with an acute severe ulcerative colitis to a regional hospital are transferred to a metropolitan hospital for specialised care. This study aimed to evaluate the outcomes and characteristics of these patients. Method: A retrospective observational cohort study was conducted to examine the 30‐day colectomy rate using prospectively collected data on 69 consecutive index cases of acute severe ulcerative colitis transferred from regional hospitals to our metropolitan hospital meeting Truelove and Witts criteria. Those that avoided colectomy were followed out to 1 year to examine outcomes. Results: The 30‐day colectomy rate was 46.4% (32/69) in regional transfer patients. Rescue therapy was administered to 65% (45/69) of patients after transfer to our metropolitan hospital. Colectomy was avoided in 55% of these patients at 30 days. Colectomy free status was maintained in 78% (29/39) of these patients. Mortality was 0% at 30 days and 1 year. Conclusion: Over 50% of the patients failing therapy in a regional centre and requiring transfer avoided short term colectomy with co‐ordinated referral for rescue therapy in a tertiary metropolitan inflammatory bowel disease unit. These patients would have ultimately required colectomy in their regional hospital without intervention. [ABSTRACT FROM AUTHOR]

Background: Patients on immunosuppression at the time of acute severe ulcerative colitis have been suggested to be at a higher risk of colectomy than those who are treatment-naïve. The aim of this study was to examine the effect of immunosuppressive therapy on the risk of colectomy. Method: We conducted a retrospective observational cohort study using prospective data examining the 30 day and 1 year colectomy rates of 200 consecutive patients with an index episode of acute severe ulcerative colitis as defined by the Truelove and Witts criteria. Results: Immunosuppression on admission was shown not to increase colectomy rate at 30 days post-admission (immunomodulator: p = 0.422, oral steroids: p = 0.555). A total of 24 patients underwent colectomy between 30 days and 1 year. A three-fold higher risk of colectomy at 1 year was seen in those requiring an immunomodulator prior to the index admission compared with those started de novo during the index admission [41% versus 14% odds ratio (OR): 2.93 (1.19–7.24 p = 0.016)]. Factors most predictive of colectomy at 30 days were abdominal radiographic colonic dilation ⩾5.5 cm, first presentation of ulcerative colitis, C-reactive protein ⩾ 45 mg/l on day 3 of therapy and bowel frequency ⩾8 on day 3. Conclusion: The need for an immunomodulator prior to admission with acute severe ulcerative colitis increases the medium-term colectomy rate by three-fold at 1 year. Prospective studies are needed to confirm these findings and develop strategies to reduce the high risk in this subgroup of patients. [ABSTRACT FROM AUTHOR]
