The epidemiology and burden of gastroparesis: Real‐world data from a large healthcare provider in Israel

Abstract

AbstractBackgroundGastroparesis is a gastrointestinal motility dysfunction characterized by delayed gastric emptying in the absence of gastric mechanical obstruction. Data on the epidemiology of gastroparesis are sparse even though the condition substantially impairs patients' quality of life. The aim of this study was to describe the epidemiology and estimate the short‐term healthcare resource use burden of gastroparesis in a large population.MethodsThis cross‐sectional study utilized computerized data from Maccabi Healthcare Services, a 2.5‐million member state‐mandated health organization in Israel. Data were collected between 2003 and 2018 to assess the prevalence of gastroparesis. Definite gastroparesis was defined by gastroparesis diagnosis and gastric emptying test. Probable gastroparesis was defined by gastroparesis diagnosis only. To compare the healthcare resource utilization (HCRU), data were also collected on controls that were individually matched (1:2) for age, sex, and comorbidities.Key ResultsA total of 522 patients with gastroparesis were identified (21.1 per 100,000 WHO age‐standardized), including 204 with definite gastroparesis (8.6 per 100,000 WHO). Male to female ratio was 1:2 and mean ± SD age of 54.7 ± 17.1 years. Diabetes accounted for 25.9% of gastroparesis cases and the rest were idiopathic. Gastroparesis patients were more likely to have cardiovascular diseases (10% vs. 6.9% for controls, p = 0.034) and lower prevalence of obesity (17% vs. 24.4%, p < 0.001). HCRU within the 2 years after index date were higher with more hospitalizations than controls (26.4% vs. 15.4%, p < 0.001), and more emergency room visits (31.6% vs. 24.1%, p = 0.002).Conclusions & InferencesGastroparesis is uncommon or under‐documented in community care settings. Gastroparesis in general is associated with cardiovascular morbidities, lower BMI, and elevated utilization of healthcare services.
