Association of Multimorbidity with Mortality and Healthcare Utilization in Chronic Kidney Disease

Objectives Chronic kidney disease (CKD) almost universally occurs in individuals with other medical problems. However, few studies have described CKD-related multimorbidity using a framework that identifies chronic conditions as concordant (having overlap in treatment goals) versus discordant (having opposing treatment recommendations) and unrelated (having no overlap, but contributing to complexity via different resource requirements). Design Retrospective cohort. Setting Veterans Affairs (VA) Medical Centers. Participants VA patients (n = 821,334) ages 18–100 years with at least one outpatient visit and incident CKD defined as an estimated glomerular filtration rate
