S1633 Helicobacter pylori Eradication Testing: Is Ordering or Completion the Issue? A Retrospective Review of a Single Health System

Abstract

Methods: We utilized the SEER Census Tract-level Socioeconomic Status and Rurality Database from 2006-2018 to calculate incidence rates (IR) and incidence rate ratios (IRR) of EOGC among Hispanic and non-Hispanic persons by census tract rural-urban location, age, year, and stage of disease. We estimated age-adjusted (to the 2000 US standard population) IRs per 100,000 persons using SEER*Stat version 8.4.0. We used Tiwari method to estimate IRRs with 95% CIs, comparing rates in 2006 and 2018 among Hispanic and non-Hispanic persons in rural and urban settings and Joinpoint software (v4.9.1.0) to evaluate annual percent change (APC). Results: Incidence rates of EOGC were significantly higher among Hispanic persons than non-Hispanic persons in both rural settings (1.44 vs 0.68 per 100,000 persons; IRR 2.12, 95% CI 1.64-2.73) and urban settings (1.75 vs 0.86 per 100,000 persons; IRR 2.04, 95% CI 1.91-2.16). Hispanic persons had higher incidences of EOGC in both rural and urban settings in every age group and stage (Table ). From 2006 to 2018 the APC was 1.40% for Hispanic persons living in rural census tracts compared to -10.
