Evaluating the burden of illness of metabolic dysfunction–associated steatohepatitis in a large managed care population: The ETHEREAL Study

Year: 2024

Type: article

Abstract: BACKGROUND: Metabolic dysfunction-associated steatohepatitis (MASH; formerly nonalcoholic steatohepatitis) is the inflammatory form of metabolic dysfunction-associated steatotic liver disease (formerly nonalcoholic fatty liver disease). MASH is a progressive disease associated with increased risk for many hepatic and extra-hepatic complications such as cirrhosis, hepatocellular carcinoma, the requirement for liver transplantation, and cardiovascular (CV)-related and kidney-related complications. It is important to understand the clinical and economic burden of MASH. OBJECTIVES: To assess and compare the clinical and economic burdens of MASH in adults with the non-MASH population in a real-world setting. METHODS: This observational, retrospective study used the Healthcare Integrated Research Database (HIRD), which contains health care claims data for commercially insured and Medicare Advantage health plan members across the United States. All-cause, CV-related, and liver-related medical costs and health care resource utilization were evaluated in patients with at least 2 diagnoses of MASH during the patient identification period (October 1, 2016, to April 30, 2022) and compared with a non-MASH cohort 1:1 matched on age, Quan Charlson Comorbidity Index, region of residence, and health plan type and length of enrollment. Generalized linear regression with negative binomial and γ distribution models were used to compare health care resource utilization and medical costs, respectively, while controlling for confounders. Covariate-adjusted all-cause, CV-related, and liver-related hospitalization rate ratios and medical cost ratios were assessed and compared for the MASH and matched non-MASH cohorts. RESULTS: < 0.0001) times higher among patients with MASH. CONCLUSIONS: Compared with those of the non-MASH cohort with similar age, Quan Charlson Comorbidity Index, health plan, region of residence, and duration of enrollment, patients with MASH had significantly higher all-cause, CV-related, and liver-related hospitalizations and medical costs.
