Cognitive impairment (CI) is common in end-stage renal disease (ESRD) patients and is associated with greater mortality. Despite this, cognitive function is not routinely measured at kidney transplantation (KT) evaluation. Cognitive assessment at KT evaluation may identify a vulnerable population and inform listing practices. Given known gender and age disparities in access to KT, we investigated the association between CI and KT listing to determine to if CI contributes to these known disparities.
We prospectively measured cognitive function at KT evaluation, using Modified Mini-Mental Status Exam (3MS), in 2,122 KT candidates. The patient's clinical teams were blinded to 3MS results. This validated tool assesses long-term memory, abstract thinking, delayed recall, and category fluency. CI was defined as a score <80 out of a possible 100 points. We used an adjusted Cox proportional hazards model to estimate the association of CI with listing stratified by sex and age.
Among KT candidates, 50.7% were African American, 60.2% were women, median age was 57.1 years and mean follow-up was 13.3 months. The overall prevalence of CI was 5.2% in women and 7.6% in men. Among candidates with no CI, 69.3% of women and 66.9% of men were listed for KT. Among candidates with CI, 3.6% of the women and 6.6% of the men were listed. CI was associated with not being listed among female candidates (HR=0.58, 95%CI: 0.37-0.92, p=0.021) but not male candidates (HR=0.90, 95%CI:0.67-1.21, p=0.5). CONCLUSIONS
Women with CI are at a significant disadvantage compared to men with CI for placement on KT waitlist. This finding may contribute to the known gender disparities in KT listing and access to KT.
