Brief Summary

Medication non-adherence is a major risk factor for graft dysfunction and graft loss among pediatric and adult transplant recipients. Rates of non-adherence in these populations are estimated between 30 and 70%, with the highest prevalence in adolescent and young adult (AYA) transplant recipients. Treatment-related factors known to impact rates of adherence include the number of medication doses per day and the number of tablets or capsules a patient takes per day, or "pill burden". One approach to minimizing dosing frequency and pill-burden includes transitioning patients to once-daily formulations. The current literature investigating utilization of once-daily immunosuppressive regimens in the AYA kidney transplant population is limited.

Outcome Measures

Primary Outcomes (7)

  • Health-Related Quality of Life: as assessed by change in PedsQL

    Pediatric Quality of Life (PedsQL) Transplant Module Version 3.0 will be used to assess quality of life prior to and after transition from twice to once daily immunosuppressant medication regimen. Health-related quality of life (HRQOL) has been defined as an individual's subjective experience of their illness, and the impact that illness and its treatment have on the individual's functioning in a variety of domains. The PedsQL is a 46-item self- and parent-report measure that rates HRQOL in 8 domains (medication adherence, medication side-effects, social relationship, physical discomfort, worries regarding health status, treatment anxiety, impact on appearance, and communication). The PedsQL Transplant Module assesses physical functioning, emotional functioning, social functioning, and school functioning and was developed through focus groups, cognitive interviews, pretesting, and field testing measurement development protocols. Higher scores indicate lower problems.

    Day 0, Day 60, Day 210

  • Adherence to medical therapies and medications: as assessed by Medication Event Monitoring System (MEMS) at Day 30

    MEMS data will be accessed prior to transition to once-daily medications (baseline adherence) and analyzed accordingly. Dates and times in which medication bottles were opened will be recorded.

    Day 30

  • Adherence to medical therapies and medications: as assessed by Medication Event Monitoring System (MEMS) at Day 60

    MEMS data will be accessed the first month of transition to once-daily medications (intervention adherence) and analyzed accordingly. Dates and times in which medication bottles were opened will be recorded.

    Day 60

  • Adherence to medical therapies and medications: as assessed by Medication Event Monitoring System (MEMS) at Day 210

    MEMS data will be accessed 6 months after transition to once-daily medications (retention adherence) and analyzed accordingly. Dates and times in which medication bottles were opened will be recorded.

    Day 210

  • Adherence to medical therapies and medications: as assessed by Change in Tacrolimus Trough Concentration Variance

    Tacrolimus trough goals between 4-7ng/mL as per Transplant Immunosuppression Protocols. Student T-test, repeated measures for parametric data). The standard deviation of tacrolimus troughs will be calculated from the 4 tacrolimus trough values obtained for clinical care purposes preceding Study Visit 1 (SD1). The standard deviation of tacrolimus troughs will be calculated again from the 4 tacrolimus trough values obtained for clinical care purposes preceding Study Visit 4 (SD2).

    Day 0, Day 30, Day 60, and Day 240

  • Adherence to medical therapies and medications:as assessed by Change in Adolescent Medication Barriers Scale (AMBS)

    17 item scale that corresponds to the Parent Medication Barriers Scale (PMBS) with 16 items. Both have strong internal consistency and are scored on a 5-point Likert scale from Strongly Disagree to Strongly Agree. A total score can be calculated, and there are subdomains of disease frustration/adolescent issues, regimen adaptation/cognitive issues, and ingestion issues, with an additional parent reminder domain on the PMBS. Lower scores indicate less barriers to medication adherence.

    Day 0, Day 60, Day 210

  • Adherence to medical therapies and medications: as assessed by Change in The Medical Adherence Measure (MAM)

    Semi-structured interview that has four general modules to assess adherence with medication, diet, exercise, and clinic attendance, as well as illness-specific modules. For the purpose of this study, the Medication and Clinic Attendance Modules will be completed. Non-adherence scores can be calculated based on the degree of adherence on a spectrum of 0%-100% adherent to capture the fluctuations and intricacies of occasional or slightly inconsistent adherence. Missed adherence score = number of doses missed out of the doses prescribed × 100%. Late adherence score = number of doses taken late out of the doses prescribed × 100%, where late is defined as greater than one hour later than the usual routine. Adherence is assessed for each medication separately and then averaged across medications.

    Day 0, Day 60, Day 210

Secondary Outcomes (5)

  • Long-term measures of graft and patient survival: as assessed by change in serum creatinine and urinary protein

    Day 0, Day 30, Day 60, Day 210, and Day 240

  • Long-term measures of graft and patient survival: as assessed by change in markers of proteinuria

    Day 30 and Day 210

  • Long-term measures of graft and patient survival: as assessed by number of episodes of rejection

    Up to Day 240

  • Long-term measures of graft and patient survival: as assessed by change in presence of donor-specific antibody monitoring

    Day 0 and Day 240

  • Long-term measures of graft and patient survival: as assessed by change in presence of BK virus screening results

    Day 0 and Day 240
