Purpose: The negative impact of non-adherence to the immunosuppressant medication (IM) regimen on transplant outcomes is well recognized. In an attempt to improve outcomes, the SIMpill® System is currently being utilized in kidney transplant(KT) recipients in a 3-year study in which allograft rejection is being evaluated.
Methods: KT recipients(n=46) were randomized to 4 groups, 2 Intervention Groups(I1 & I2) or 2 Control Groups(C1 & C2). Subjects enrolled in I1, I2 and C1 received the SIMpill® Electronic Medication Adherence Monitoring System. C2 did not receive a device. This system is a medication-dispensing device that communicates and stores timing of openings, or doses taken to a secure server. The Intervention Group subjects received notification if a scheduled IM dose was missed via text message and/or email. In addition, in I2, if a scheduled dose was missed despite the reminder message, a study provider was notified, enabling intervention
. In C1 no one received any feedback, but their adherence is stored on the server for analysis.
Results: At one year, 46 KT recipients were enrolled with an average follow-up of 334 days (median=413.5[range 118-559]). Seven of 9 rejections were ACR where 2 of the 9 were ABMR. Five of 7 ACR biopsies were categorized as Banff grade ≤ 2 while the other 2 were classified as borderline. Five of 9 rejection episodes resulted in hospital admission totaling 34 days. One of the 9 subjects with ACR experienced graft failure and died on post-transplant day 140
| Adherence Parameter | Intervention Group 1 & 2 N=20 | Control Group 1 N=26 | p-value |
| # of Biopsies performed | 4 | 9 | p=NS |
| Biopsy Proven Rejection(% of group) | 0(0) | 9(19.2) | <0.005 |
| LOS for treatment days | 0 | 34 | <0.001 |
| Total Doses Taken % | 90 | 84 | <0.03 |
| Days with Correct Dosing % | 87 | 74 | <0.02 |
.
Conclusions: Preliminary 1-year results demonstrate that utilization of the SIMpill® with feedback on adherence shows a potential reduction in biopsies performed, and rejection episodes as well possibly reducing hospitalizations and cost related to rejection.
