Introduction: Gastrointestinal (GI) bleeding is a critical complication for chronic kidney disease (CKD) patients, raising mortality risks due to physiological changes and comorbidities. This study analyzes GI bleeding-related mortality trends among CKD patients in the United States (US) from 1999 to 2020.

Methods: Data from the Centers for Disease Control and Prevention Wide‐ranging Online Data for Epidemiologic Research (CDC WONDER) on US CKD patients aged ≥ 25 years, with CKD and GI bleeding listed as underlying or contributing causes of death, were analyzed for GI bleeding-related mortality. Age‐adjusted mortality rates (AAMRs) per 100,000 were calculated, and Joinpoint regression assessed trends. Annual percentage change (APC), and average annual percentage change (AAPC) stratified by year, gender, race, and geographic region.

Results: A total of 41,697 GI bleeding–related deaths occurred among CKD patients. AAMR increased from 1.1 per 100,000 in 1999 to 3.0 in 2020 (AAPC 4.2 %; 95 % CI: 2.9–5.4 %). From 1999 to 2009, AAMR declined to 0.8 (APC –2.9 %; 95 % CI: –8.2–0.0 %), surged to 2.0 by 2012 (APC 31.4 %; 95 % CI: 12.5–41.9 %), then rose gradually to 3.0 by 2020 (APC 4.4 %; 95 % CI: –2.2–7.1 %). Males had higher AAMR (2.1; AAPC 3.9 %; 95 % CI: 2.6–5.0 %) than females (1.3; AAPC 4.3 %; 95 % CI: 2.9–5.4 %). By race, non‐Hispanic Black patients had the highest AAMR (3.4; AAPC 2.7 %; 95 % CI: 1.3–4.2 %), with declines from 1999–2008, a sharp rise through 2011, and a moderate increase thereafter. Non‐Hispanic Asian/Pacific Islander patients had AAMR 1.8 (AAPC 3.8 %; 95 % CI: 2.1–7.0 %), Hispanic patients 1.8 (AAPC 3.3 %; 95 % CI: 1.7–4.8 %), and non‐Hispanic White patients 1.4 (AAPC 4.5 %; 95 % CI: 3.4–5.6 %). Non‐metropolitan areas recorded AAMR 1.8 (AAPC 4.1 %; 95 % CI: 2.8–5.4 %) compared to metropolitan areas 1.6 (AAPC 4.1 %; 95 % CI: 2.8–5.7 %). Regionally, the Midwest had AAMR 1.7 (AAPC 4.1 %; 95 % CI: 2.9–5.3 %), the West 1.6 (AAPC 4.8 %; 95 % CI: 3.2–6.2 %), the South 1.6 (AAPC 4.0 %; 95 % CI: 2.4–5.4 %), and the Northeast 1.5 (AAPC 3.6 %; 95 % CI: 1.9–5.1 %). States in the top 90th percentile of AAMR included South Carolina, District of Columbia, and Rhode Island (2.6); South Dakota (2.4); and Washington and North Dakota (2.3).

Discussion: GI bleeding-related mortality among CKD patients in the U.S. has markedly increased over the past two decades. Demographic and geographic disparities underscore the need for targeted public health efforts to improve outcomes for at-risk CKD patients.
