Purpose: To evaluate the impact of and electronic feedback system (EFS), SIMpill Medication Adherence System®, on medication adherence in patients who have received a solid organ transplant.
Methods: A total of 89 solid organ transplant recipients were randomized to 1 of 4 groups; 2 intervention groups (I1 and I2) & 2 control groups (C1 and C2). Subjects in I1 or I2 received EFS, a medication-dispensing device that communicates timing of openings or doses taken to a secure server. 
If a medication dose is missed a text reminder message is sent to the subject (I1). In addition to patient reminders, providers were notified if consecutive doses were missed over a 72 hour period (I2), enabling intervention. C1 received an EFS device but feedback was not provided to the patient or provider. C2 did not receive an EFS device.
Results: A total of 39 subjects from two subgroups, I1 (N=20) and C1 (N=19), were selected for analysis with Mann-Whitney U tests. A majority of patients used the device for greater than 6 months. Median comparison of total doses taken, days with correct dosing, and doses taken within 2 hours of target time were significantly greater in I2 compared to C1.
| Adherence Parameter | Intervention Group 2 (N=20) | Control Group 1 (N=19) | p value |
| Total Doses Taken (% Median) |
97 | 88 | <0.001 |
| Days with Correct Dosing (% Median) |
94 | 74 | <0.001 |
| Doses Taken within Two Hours of Target Time (% Median) |
65 | 52 | <0.001 |
Conclusion: The use of an EFS, such as the SIMpill Medication Adherence System®, may improve adherence in solid organ transplant recipients, may allow for identification of medication non-adherence, and may facilitate provider intervention for non-adherence.
