Introduction: Donor nephrectomy (DN) is a procedure performed to provide recipients with a kidney to treat end-stage renal disease. The following analysis evaluated depression diagnosis in DN patients compared to controls. Methods: DN patients and matched controls were identified between 2000 and 2009 from the Statewide Planning and Research Cooperative System database. Cohorts were tracked for depression incidence. Multivariable logistic regression was used to determine independent predictors of a postoperative depression diagnosis. Results: The total study cohort included 2108 DN cases and 2108 controls. In both donors and controls, the baseline rate of depression was 0.95% (n = 20). The 5-year incidence of depression diagnosis after exposure increased in both cohorts (donors: 2.5%, n = 53; controls: 7.2%, n = 152; P < .001). The 5-year relative risk for developing depression was 2.65 (CI 1.59-4.42, P = .0002) in donors and 7.60 (CI 4.79-12.07, P < .001) in controls. On multivariable regression, being a donor was associated with reduced risk of developing postoperative depression (OR = 0.322, CI 0.233-0.445, P < .001), and the greatest risk factor for postoperative depression was a prior depressive diagnosis (OR = 7.811, CI 3.814-15.997, P < .001). Conclusion: Our analysis shows that the strongest risk factor for depression was a prior diagnosis of depression. However, willingness to undergo donor nephrectomy is associated with less subsequent depression than the control population, suggesting that kidney donors may be a more resilient cohort.
