S203 Resurgence of Mortality Trends From Pancreatobiliary Disorders in the United States Population: Insight From the CDC WONDER Database (1999 to 2023)

Introduction: Although healthcare has improved over the years, literature data indicate that deaths from pancreatobiliary disorders remain consistently high. Despite this burden, national-level trends over an extended period remain underexplored. This study aims to analyze long-term mortality patterns associated with pancreatobiliary disorders among adults in the United States from 1999 to 2023. Methods: We retrospectively evaluated pancreatobiliary disorders-related mortality data (ICD-10 Codes: K80-86) from the CDC WONDER database for individuals aged ≥45 in the United States from 1999 to 2023. Age-adjusted mortality rates (AAMR) per 100,000 people were extracted and stratified by year, sex, race/ethnicity, Hispanic/non-Hispanic origin, 2013 urbanization classification, and census region. Annual percentage changes (APC) with 95% confidence intervals (CIs) were calculated using the Joinpoint Regression Program, with statistical significance set at P < 0.05. Results: A total of 202,383 deaths related to pancreatobiliary disorders occurred from 1999 to 2023, with an overall AAMR of 6.73 per 100,000 population. From 1999 to 2018, the AAMR declined with an APC of -0.92 (95% CI: -1.21 to -0.68; P < 0.000001), followed by a sharp rise by 2023 (APC: 2.83; 95% CI: 1.33 to 5.50; P = 0.0008). Men had a higher AAMR (7.97) than women (5.72). Among racial groups, Asians or Pacific Islanders showed a consistent decline (APC: -1.10; 95% CI: -1.65 to -0.40; P = 0.002000). Blacks or African Americans experienced a significant increase in AAMR from 2018 to 2023 (APC: 4.37; 95% CI: 0.75 to 12.95; P = 0.019996). Similarly, Whites showed a rising trend during the same period (APC: 3.03; 95% CI: 1.29 to 6.95; P = 0.001200). CENS-R1: Northeast (2018 to 2023) and CENS-R2: Midwest (2017 to 2023) showed upward trends with APCs 3.97 (95% CI: 2.42 to 6.51; P < 0.000001) and 2.58 (95% CI: 0.85 to 7.20; P = 0.000400), respectively. Large Central Metro counties showed a stable decline from 2001 to 2023 (APC: -1.37; 95% CI: -1.79 to -1.22; P = 0.001200). The non-Hispanic population exhibited higher AAMR than the Hispanic population (6.75 vs 6.57). Conclusion: Despite initial declines, mortality from pancreatobiliary disorders in the United States has increased significantly since 2018, with notable disparities across demographic and regional groups. Targeted prevention and equitable access to care are essential to stem the recent upsurge in pancreatobiliary-related mortality.
