Introduction: The prevalence of obesity in the United States (US) has continued to rise from 30.5% to 41.9% in the years 2017-2020. The annual estimated medical cost related to obesity in the US was about $173 billion in 2019; with obese patients incurring a $1,861 higher medical costs compared to normal weight patients. Numerous studies have investigated the link between obesity and diverticulitis; which remains one of the most common gastrointestinal tract diagnoses among hospitalized patients in the US. However, data on the cost and burden of diverticulitis in hospitalized obese patients is lacking. We evaluated this burden in obese patients with diverticular disease using outcomes of in-hospital mortality, length of stay and total hospital charges.

Methods: We conducted a nationwide review from 2016 to 2017 using the National Inpatient Sample (NIS) data. NIS is the largest publicly available all-payer inpatient database in the United States with more than seven million hospital stays each year, as a part of the Healthcare Cost and Utilization Project (HCUP). Patients ≥ 18 years old obese patients with diverticular disease were identified using the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes. Adjusted odds ratio (OR) and confidence intervals (CI) at 99% were reported.

Results: We identified 1,744,106 patients who had obesity patients. The mean age of participants was 56 years with a female predominance at 61.8%. Obese patients with complicated small bowel diverticulitis were more likely to die during the hospital stay (2.4, 1.8-3.2), and incurred more charges compared to non-obese patients with complicated small bowel diverticulitis ($24,042, 17,366-30,718). A similar trend was observed in obese patients with simple large bowel diverticulitis (Table 1).

Discussion: We found that hospitalized obese patients with complicated small bowel diverticulitis were more likely to die during that hospitalization, and to incurred higher hospital charges compared to non-obese patients with diverticulitis. This study raises awareness regarding the risk incurred by this hospitalized patient population, and may require more attention to minimize such burden.
