Abstract
AbstractIntroductionSelf‐reported measures of immunosuppression adherence have been largely examined in research settings.MethodsIn this single center study of 610 kidney transplant recipients, we examined if a voluntary, non‐anonymous self‐report measure could identify non‐adherence in a routine clinic setting and how patients perceived such a measure. Non‐adherence was measured using the Basel Assessment of Adherence to Immunosuppressive Medications Scale (BAASIS) and patient perception was elicited using a customized questionnaire.ResultsNon‐responders to the survey (15%) were younger, more likely to be black, and less likely to have had a pre‐emptive transplant. Among complete responders (n = 485), 38% reported non‐adherence with non‐adherent patients being younger (54 y vs. 60 y; p = .01), less likely to have been on dialysis pre‐transplant (59% vs. 68%; p = .04), further out from transplant (37 vs. 22 months; p < .001) and had more rejections in the preceding year (8% vs. 3%; p = .02). Self‐reported non‐adherence was associated with higher calcineurin inhibitor intra‐patient variability (27.4% vs. 24.5%; p = .02), but not with donor‐specific antibody detection (27.8% vs. 21.2%, p = .15). Of patients providing feedback (n = 500), the majority of patients felt comfortable reporting adherence (92%), that the survey was relevant to their visit (71%), and that the survey did not interfere with their clinic visit (88%).ConclusionIn summary, a self‐reported questionnaire during clinic visits identified immunosuppression non‐adherence in a significant proportion of patients and was well received by patients. Integrating self‐report measures into routine post‐transplant care may enable early identification of non‐adherence.
