Summary Socioeconomic deprivation ( SED ) influences likelihood of pre‐emptive kidney transplantation ( PET ), but the mechanisms behind this are unclear. We explored the relationships between SED and patient characteristics at referral, which might explain this discrepancy. A retrospective cohort study was performed. SED was measured by Scottish Index of Multiple Deprivation ( SIMD ). Logistic regression evaluated predictors of PET . A competing risks survival analysis evaluated the interaction between SED and progression to end‐stage kidney disease ( ESKD ) and death. Of 7765 patients with follow‐up of 5.69 ± 6.52 years, 1298 developed ESKD requiring RRT ; 113 received PET , 64 of which were from live donors. Patients receiving PET were “less deprived” with higher SIMD (5 ± 7 vs. 4 ± 5; P = 0.003). This appeared independent of overall comorbidity burden. SED was associated with a higher risk of death but not ESKD . Higher SIMD decile was associated with a higher likelihood of PET ( OR 1.14, 95% CI 1.06, 1.23); the presence of diabetes and malignancy also reduced PET . SED was associated with reduced likelihood of PET after adjustment for baseline comorbidity, and this was not explained by risk of death or faster progression to ESKD . Education and outreach into transplantation should be augmented in areas with higher deprivation.
