title: Predictors and Moderators of Educational Interventions to Increase the Likelihood of Potential Living Donors for Black Patients Awaiting Kidney Transplantation.
abstract: Our aim was to identify predictors and moderators of the effects of a house calls (HC) educational intervention, relative to a group-based (GB) intervention and to individual counseling (IC), in a randomized controlled trial to increase the likelihood of having living donor (LD) evaluations initiated and live donor kidney transplantation (LDKT). Black adults wait listed for kidney transplantation (N = 152) were randomized into one of the three educational conditions. We examined demographic, clinical, psychosocial, and socio-contextual baseline characteristics as predictors and moderators of having a potential LD initiate evaluation. HC assignment (OR =2.024.7311.05, P = 0.001), younger age (OR =0.910.940.98, P = 0.001), more willingness to discuss donation with others (OR =1.081.371.75, P = 0.01), and larger social network (OR =1.011.091.18, P = 0.04) were significant multivariable predictors of having ≥1 LD initiate evaluation. Age (P = 0.03) and social network size (P = 0.02) moderated the effect of HC relative to IC and GB, but not GB relative to IC, on LD evaluation initiation. Our findings suggest that HC is most effective for patients <60 years old and those with average or large social network size.
