Background:
Diverticular disease has a changing disease pattern with limited epidemiological data.
Aim:
To describe diverticular disease admission rates and associated outcomes through national population study.
Methods:
Data were obtained from the English 'Hospital Episode Statistics' database between 1996 and 2006. Primary outcomes examined were 30-day overall and 1-year mortality, 28-day readmission rates and extended length of stay (LOS) beyond the 75th percentile (median inpatient LOS = 6 days). Multiple logistic regression analysis was used to determine independent predictors of these outcomes.
Results:
Between the study dates 560 281 admissions with a primary diagnosis of diverticular disease were recorded in England. The national admission rate increased from 0.56 to 1.20 per 1000 population/year. 232 047 (41.4%) were inpatient admissions and, of these, 55 519 (23.9%) were elective and 176 528 (76.1%) emergency. Surgery was undertaken in 37 767 (16.3%). The 30-day mortality was 5.1% (n = 6735) and 1-year mortality was 14.5% (n = 11 567). The 28-day readmission rate was 9.6% (n = 21 160). Increasing age, comorbidity and emergency admission were independent predictors of all primary outcomes.
Conclusions:
Diverticular disease admissions increased over the course of the study. Patients of increasing age, admitted as emergency and significant comorbidity should be identified, allowing management modification to optimize outcomes.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
