Transplant-specific risk factors for rejection are well documented, yet psychosocial variable correlation with rejection risk is not; this analysis seeks to determine the relationship between psychosocial variables and rejection outcomes.
Psychosocial data was collected from pre-transplant evaluation reports for patients transplanted from 2006-2016. Patients without psychosocial records were excluded. A multivariate logistic regression was performed using STATA software with rejection as the dependent variable.
Adequate drug coverage was significant for decreased rejection risk (OR=0.27,p<0.001), while lacking follow up compliance was significant for increased rejection risk (OR= 5.17, p<0.001). Other variables were not statistically significant.

This analysis considers rejection risk in the setting of a multivariate analysis with other known risk factors for rejection. Both protective factors and risk factors were identified, showing that pre-transplant evaluation psychosocial factors impact post-transplant outcomes.
