Background: COPD is the third leading cause of mortality worldwide. CKD is a major healthcare concern that commonly coexists with COPD, increasing morbidity and mortality of both conditions. Methods: Utilizing data from the CDC WONDER database, COPD and CKD-related deaths from 1999 to 2020 were identified. Age-adjusted mortality rates (AAMRs) per 100,000 individuals were determined, using ICD-10 codes J40-44 and N18 for COPD and CKD, respectively. Joinpoint regression was used to analyze trends and annual percentage change (APC) variations for deaths stratified by year, sex, and geographical groups. Results: From 1999 to 2020, 172,439 COPD and CKD-related deaths were identified. Most occurred in inpatient medical facilities (44%), followed by nursing homes/long-term care facilities (23.6%), decedent’s homes (23.4%), and hospice/outpatient/ER facilities (5.5% each). Overall, AAMRs increased from 1999 to 2020 (APC 3.82). Males had higher AAMRs (27.49) than females (13.38), although the rise was more significant in females. When stratified by race, there was a consistent rise in AAMRs across all groups. Most notably, NH American Indian/Alaska Natives had the greatest increase in AAMR (21.05), while NH Asian/Pacific Islanders had the least (8.83). Non-metropolitan areas had greater AAMRs than in urban areas (23.21 vs. 17.87). AAMRs also varied regionally: Midwest (28.43), South (23.49), West (22.44), and Northeast (21.62). States in the upper 90th percentile of COPD & CKD-related deaths included West Virginia, North Dakota, Kentucky, Vermont, and Indiana, which had four times the AAMRs of states in the lower 10th percentile. Conclusion: The consistently rising mortality rate in COPD and CKD patients raises an important need to be explored. Persistent disparities exist, particularly among NH American Indian/ Pacific Islander males and individuals in the Midwest and rural areas, highlighting the need for targeted interventions for vulnerable groups and regions.
