A Continuous Adherence Score, but Not Dichotomous BAASIS Screening, Is Associated with Graft Function in Kidney Transplant Recipients

Background/Objectives: Non-adherence to immunosuppressive medication is a principal modifiable determinant of kidney allograft survival, yet its associations with objective graft function remain inconsistent, in part because the Basel Assessment of Adherence to Immunosuppressive Medications Scale (BAASIS) dichotomises infrequent and persistent non-adherence together. We tested whether a continuous adherence measure and psychological acceptance of illness are more closely associated with graft function than BAASIS.
