Abstract
BACKGROUND Patients with inflammatory bowel disease (IBD) may be at increased risk for acute diverticulitis (AD) complications due to luminal inflammation and immune modifying medications. We aimed to assess outcomes of acute diverticulitis in patients with IBD. METHODS A propensity-matched analysis of the National Inpatient Sample database was performed to assess outcomes of AD in adult patients (older than 18 years) from 2004 to 2013 with and without IBD. Outcomes included in-hospital mortality, need for percutaneous drainage, surgery, venous thromboembolism (VTE), total cost, and length of stay (LOS). A subgroup analysis comparing patients with Crohn's disease (CD) and ulcerative colitis (UC) was performed. RESULTS After propensity matching, compared with non-IBD patients (n = 15,015); Patients with IBD (n = 15,106) did not have significantly higher rate of mortality and surgical intervention but had significantly higher rates of percutaneous drainage (4% vs 3.4%; P = 0.002), VTE (1.1% vs 0.7%; P < 0.001), longer LOS (P < 0.001), and total cost (P < 0.001). Compared with CD, UC was associated with significantly higher rates of surgical intervention (20.3% vs 19%; P = 0.04), in-hospital mortality (1.4% vs 0.4%; P < 0.001), VTE (1.6% vs 0.7%; P < 0.001), total cost ($41,672 ± $61,358 vs $33,951 ± $54,376; P < 0.001), and LOS (6.4 ± 6.4 vs 5.7 ± 5.3; P < 0.001). From 2004 to 2013, there was a significant increase of IBD (range 0.5% to 0.8%; P = < 0.001) in AD patients with overall stable mortality (0.5% to 1.0%; P = 0.47) of AD in patients with IBD. CONCLUSIONS Patients with IBD are at increased risk of complicated diverticulitis and worse outcomes compared with matched controls. Optimal AD management strategies in IBD are needed.

Abstract
Question Does an association exist between high cost-sharing insurance plans and patient presentation with and surgical management of acute appendicitis or acute diverticulitis? Findings In this cohort study of 151 852 patients, higher patient cost sharing was associated with lower odds of presenting with early, uncomplicated disease, receiving optimal surgical care, and receiving minimally invasive surgery. Meaning Policymakers should be aware of the clinical and financial implications of patient health care behaviors associated with increased cost sharing. Importance Treatment delays are associated with increased morbidity and cost of disease, although the extent to which cost sharing influences timely presentation and management of acute surgical disease remains unknown. Given recent policy changes using cost sharing to modify health care behavior, this study examines the association of cost sharing with the health of the patient at presentation and with receipt of optimal or minimally invasive surgery. Objective To assess whether cost sharing is associated with the likelihood of early, uncomplicated patient presentation or with surgical management of 2 representative emergency general surgery diagnoses: acute appendicitis and acute diverticulitis. Design, Setting, and Participants This cohort study used Health Care Cost Institute claims from January 1, 2013, through December 31, 2017, to analyze data of commercially insured individuals hospitalized for acute appendicitis or diverticulitis. In total, 151 852 patients in the data set aged 18 to 64 years and presenting with acute appendicitis or diverticulitis were included as identified using the International Classification of Diseases, Ninth Revision and the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision. Data were analyzed from January 2020 through February 2021. Exposures The primary exposure was patient total cost sharing incurred for the index hospitalization, defined as their summed deductible, copayments, and coinsurance. Main Outcomes and Measures The primary outcome was early, uncomplicated disease presentation. Secondary outcomes were receipt of optimal surgical care and minimally invasive surgery if undergoing an operation. Analyses were conducted with multivariable logistic regression models to adjust for patient characteristics and community-level socioeconomic and geographic factors. High cost sharing was defined as quartile 4 (>$3082), and low cost sharing as quartile 1 ($0-$502). Results Among 151 852 patients, 52.4% were men, and the total cost-sharing median was $1725 (interquartile range, $503-$3082). Higher cost sharing was associated with lower odds of early, uncomplicated disease presentation (odds ratio, 0.63; 95% CI, 0.61-0.65). Patients with higher cost sharing were less likely to receive optimal surgical care (odds ratio, 0.96; 95% CI, 0.93-0.99) or minimally invasive surgery (odds ratio, 0.89; 95% CI, 0.84-0.95). Conclusions and Relevance The findings of this cohort study suggest that, as policymakers debate the degree of cost sharing in public and private insurance plans, attention should be given to the clinical and financial implications associated with care delays.

Abstract
OBJECTIVES Acute diverticulitis is the third most frequent cause of gastrointestinal admission in the USA. We sought to determine the incidence of recurrence within a 90-day period and determine its impact on mortality and hospital utilization. METHODS Nationwide Readmission Database (NRD) 2016 was used to identify patients ≥ 18 years old with a principal diagnosis of acute diverticulitis who were readmitted for recurrence within 90 days. The primary outcome was 90-day readmission rate for acute diverticulitis, and predictors were analyzed using a multivariate regression analysis. Secondary outcomes were mortality and hospital resource utilization. RESULTS A total of 171,238 admissions were included which met inclusion criteria. Ninety-day readmission for acute diverticulitis after index diverticulitis hospitalization was 8.9%. Readmissions were associated with in-hospital additional total cost of $444,726,560 and 65,685 total hospital days and mortality rate of 4.69% compared with mortality rate of 5.20% on index hospitalization (p < 0.01). In multivariable analysis, increased odds of readmission were associated with disposition against medical advice (OR 1.75, 95% CI 1.31-2.33), younger age (OR 0.98, 95% CI 0.98-0.99), and shorter length of stay (OR 0.99, CI 0.98-0.99). CONCLUSIONS Acute diverticulitis is frequently associated with recurrence within 90 days and bears a substantial financial and mortality burden. Targeted interventions are needed to minimize readmissions in identified subpopulations.

Abstract
BACKGROUND Owing to improved quality of computed tomography, a new category of complicated acute diverticulitis, including patients with pericolic air but without abscess formation, can be defined (Hinchey 1a). Recent studies question whether this new category of acute diverticulitis could be treated as uncomplicated cases. The aim of our study is to report on the clinical course of acute diverticulitis Hinchey 1a in current clinical practice. METHODS For this multicenter retrospective cohort study, patients presenting at the emergency department with Hinchey 1a acute diverticulitis as demonstrated by computed tomography scan, were identified. The primary outcome measure was successful conservative treatment with observation alone, antibiotics, and/or hospital admission. Readmissions, percutaneous drainage of abscesses, and emergency operations were considered as failure. RESULTS Between October 2016 and October 2018, 1,199 patients were clinically suspected for acute diverticulitis, of whom 101 (8.4%) were radiologically diagnosed to have type 1a acute diverticulitis (average age 57 (±13) years, 45% female) and started with conservative treatment. This was successful in 86 (85%) patients. One of the 15 unsuccessfully treated patients (1%) received percutaneous drainage of an abdominal abscess. Surgery was required in 9 cases (9%) after a median time of 6 days (range, 3 to 69 days). Although a difference in the volume of extraluminal air on computed tomography scan was found, this was not shown to be a risk factor for the clinical course. CONCLUSION Patients with type 1a acute diverticulitis can be treated successfully by conservative therapy in the majority of cases (85%). More research is required to define predictive factors for successful conservative management.

Abstract
BACKGROUND Acute diverticulitis (AD) is an increasingly common cause of acute hospital admissions. An understanding of its economic burden is necessary to plan resource allocation, and for targeting health research funding. The aim of this study is to obtain an accurate estimate of the cost of AD, accounting not only for the initial episode, but all related costs incurred during long-term follow-up. METHODS The study captures a cohort of patients who had an initial admission for AD from 1 January 2012-31 December 2012, and their treatment over a 6-year period. Cases were identified from a prospectively maintained database, with AD confirmed by computed tomography scan. The primary outcome was total healthcare cost related to AD. RESULTS The study included 170 patients. The total cost was NZD1 956 859 with a median cost per patient of NZD4814. A total of 57% of the cost was incurred for the initial inpatient admission, with the remaining 43% incurred through re-admission, follow-up appointments, investigations and management. Half of the total cost was incurred by 11.8% of the cohort. In multivariate analysis, high cost of care was significantly associated with complicated and recurrent disease, operative intervention and length of stay. CONCLUSION This study provides an accurate estimate of the overall cost of AD and its sequelae. There are considerable long-term costs associated with the index episode and a large proportion of the expenditure is incurred by a small group that included those with complicated disease. These findings are important for healthcare resource allocation and for targeting health research funding.

Abstract
Background and Aim Inflammatory bowel disease (IBD) and diverticulitis both increase morbidity, especially when associated with in‐patient hospitalization. This study aimed to evaluate whether hospitalization burden differs for diverticulitis in patients with a history of Crohn's disease (CD) compared to ulcerative colitis (UC). Method All patients hospitalized for acute diverticulitis with pre‐existing UC or CD in 2014 were selected using the national in‐patient sample. Cases were identified using the International Classification of Diseases, Ninth Edition codes. Primary outcomes were mortality, cost of admission, length of stay (LOS), and colectomy. Results A total of 1815 patients were admitted with diverticulitis, and those with CD had a hospitalization associated with decreased cost (aOR −14 537, 95% CI −27 316 to −1758; P = 0.026) and LOS (aOR −1.31, 95% CI −2.41 to −0.208; P = 0.02) compared to UC. A second analysis comparing diverticulitis hospitalization between those with CD and those with the absence of IBD showed no significant difference in mortality (aOR 2.47, 95% CI 0.59 to 10.36; P = 0.22), LOS (aOR 0.03, 95% CI −0.47 to 0.54; P = 0.92), or cost of admission (aOR −2196, 95% CI −6933 to 2539; P = 0.36) between the cohorts. Conclusion Patients with UC have worsened hospitalization outcomes when being treated for diverticulitis compared to CD. While the findings may be a result of a difference in colectomy rates, the etiology may also be multifactorial. These conclusions have not been previously described, and further investigations would better characterize these associations.

Abstract
Background and Objectives: The diverticular disease includes a broad spectrum of different "clinical situations" from diverticulosis to acute diverticulitis (AD), with a full spectrum of severity ranging from self-limiting infection to abscess or fistula formation to free perforation. The present work aimed to assess the burden of complicated diverticulitis through a comparative analysis of the hospitalizations based on the national administrative databases. Materials and Methods: A review of the international and national administrative databases concerning admissions for complicated AD was performed. Results: Ten studies met the inclusion criteria and were included in the analysis. No definition of acute complicated diverticulitis was reported in any study. Complicated AD accounted for approximately 42% and 79% of the hospitalizations. The reported rates of abscess varied between 1% and 10% from all admissions for AD and 5-29% of the cases with complicated AD. An increasing temporal trend was found in one study-from 6% to 10%. The rates of diffuse peritonitis ranged from 1.6% to 10.2% of all hospitalizations and 11% and 47% of the complicated cases and were stable in the time. Conclusions: The available data precluded definitive conclusions because of the significant discrepancy between the included studies. The leading cause was the presence of heterogeneity due to coding inaccuracies in all databases, absence of ICD codes to distinguish the different type of complications, and the lack of coding data about some general conditions such as sepsis, shock, malnutrition, steroid therapy, diabetes, pulmonary, and heart failure.

Abstract
BACKGROUND Older age has long been linked to risk of diverticulitis, but the epidemiology is seldom described for a national population. The aim of this study was to investigate age- and gender differences in incidence, temporal trends, lifetime risk and prevalence related to acute diverticulitis hospitalisations in New Zealand. METHODS Records of all hospitalisations with diverticulitis the primary diagnosis were obtained from the Ministry of Health for the period 2000-2015. The first acute diverticulitis admission recorded for an individual was taken as an incident event; all others were classified as recurrent. Trends in age- and sex-specific and age-standardised incidence rates are described, and lifetime risk and prevalence estimated. RESULTS Over the 16 years from 2000 to 2015, 37,234 acute hospitalisations for diverticulitis were recorded in 28,329 people aged 30 + years (median = 66 years). Rates of incident hospitalisations rose with age, from 5/10,000 person-years at age 50-54 years to 19/10,000py by age 80-84 years. Rates for women were lower than men before age 55 years, but higher thereafter. Age-standardised rates rose 0.2/10,000py annually, but approximately doubled among men aged < 50 years. Lifetime risk was estimated at over 5%, with the prevalence pool rising to over 1.5% of the population aged 30+ in 2030. CONCLUSIONS Rapid increases in diverticulitis admissions among young men since 2000 correspond with increases reported elsewhere but remain unexplained; notably young women follow similar trends 5-10 years later. Increasing incidence, combined with population ageing, adds urgency to explain diverticular formation, to understand factors that trigger or provoke their inflammation/infection, and to clarify treatment and (self-)management pathways.
