Health disparities in time to diagnosis and survival post-diagnosis of cirrhosis in individuals with alcohol use disorder: A retrospective cohort study.

OBJECTIVE: This study investigates the impact of race, gender, and ethnicity on the progression from diagnosis to cirrhosis and subsequent survival in patients with alcohol use disorder, with a specific focus on identifying potential disparities in health outcomes.

METHOD: Employing a STROBE-compliant, retrospective cohort design, we analyzed data from patients diagnosed with alcohol use disorder from January 2000 to December 2022, using the University of California Health Data Warehouse. We estimated survival functions using the Kaplan-Meier method and assessed demographic associations using both bivariate and multivariate Cox proportional hazards models.

RESULTS: The analysis highlighted a significant association between Hispanic ethnicity and an accelerated timeline for both the diagnosis of alcohol-related cirrhosis following diagnosis of alcohol use disorder and mortality post-cirrhosis diagnosis. The former was evident only in bivariate analysis, but the latter association persisted in multivariate analysis. Gender did not demonstrate a significant correlation with the time to these outcomes, though multiracial identification emerged as a protective factor.

CONCLUSIONS: The study reveals critical health disparities in the progression and outcomes of cirrhosis, particularly between Hispanic and non-Hispanic patients. These findings underscore the urgent need for targeted healthcare interventions and policies that address these disparities. Future research should delve deeper into the multifaceted factors influencing these outcomes, facilitating the development of more nuanced and effective prevention and treatment strategies for alcohol use disorder and its severe complications.
