Outcome Measures
The primary outcome measures were focused on medication adherence. We included medication adherence from studies involving eHealth interventions for transplant recipients as objective measures (medication compliance monitored by electronic devices, and clinical measures such as tacrolimus serum concentration levels, coefficient of variation for blood tacrolimus level,the proportion of patients obtaining normal tacrolimus trough variability) and subjective measures (self-report questionnaires, such as Basel Assessment of Adherence to Immunosuppressive Medication Scale). Secondary outcome includes renal function, rejection and patient satisfaction.
