Description
Summary:Background: Scarce data are available on the epidemiological trend of diverticulitis and its financial burden in Italy. The aim of this work was to explore a potential variation in the rate and costs of hospital admissions for uncomplicated and complicated diverticulitis over the last decade. Methods: We selected all hospitalizations for diverticulitis of residents in the Abruzzo Region, Italy between 2005 and 2015. Age-standardized hospitalization rates (HRs) per 100,000 inhabitants for overall, uncomplicated and complicated diverticulitis were calculated. A linear model on the log of the age-standardized rates was used to calculate annual percentage changes (APC). Costs were derived from the official DRG tariff. Results: From 2005 to 2015, the HR for acute diverticulitis increased from 38.9 to 45.2 per 100,000 inhabitants (APC + 1.9%). The HR for complicated diverticulitis increased from 5.9 to 13.3 (APC + 7.6%), whereas it remained stable for uncomplicated diverticulitis. The mean hospital cost was 1.8-times higher for complicated diverticulitis compared with that for uncomplicated disease and 3.5-times higher for patients with a surgery stay compared with that for patients with a medical stay. Conclusion: During the last decade, in the Abruzzo Region, the HRs for diverticulitis and their costs increased significantly, mainly due to disease complications. Further studies are needed to explore strategies to prevent complications and to realise cost-saving policies.
