Self-reported non-adherence to immunosuppressive medication detected by the BAASIS predicts allograft rejections in kidney transplant recipients

Of the total study cohort [median age 56 years (IQR 46-63), 75 (33%) female], 125 recipients (55%) reported non-adherence at least once. Self-reported non-adherence increased within the first 3 months from 11% to 31% and remained between 27% and 32% at months 6 to 24 post-transplant. Our findings support the clinical value of the BAASIS. Its implementation into routine post-transplant care may facilitate the identification of clinically relevant medication non-adherence, enabling timely interventions.
