Study summary

We will conduct a two-group randomized controlled trial to examine the eMocha DOT intervention with pediatric HT recipients.In this population, medication nonadherence remains a primary cause of late acute rejection (LAR) episodes, increased number of hospitalizations, graft failure, and patient mortality. Herein, we propose an innovative approach to promote medication adherence and improve patient and graft outcomes.

Read the detailed description

Few interventions have proven to be successful in promoting medication adherence and impacting short- and long-term post-transplant outcomes in adolescent heart transplant (HT) recipients. Improving adherence is a persistent challenge with youth experiencing chronic health conditions, especially among adolescent transplant recipients. Adolescent organ transplant recipients experience unique challenges remaining adherent to the complex post-transplant regimen, with rates of non-adherence as high as 40% to 60%. In this population, medication non-adherence remains a primary cause of late acute rejection (LAR) episodes, increased number of hospitalizations, graft failure, and patient mortality. Herein, we propose an innovative approach to promote medication adherence and improve patient and graft outcomes.

What researchers measure

Primary outcomes

  1. Medication adherence based on medication level variability index

    medication level variability index (MLVI). MLVI is calculated as the Standard Deviation of a set of at least 3 tacrolimus trough blood levels for each participant.

    Time frame: 12 weeks

  2. Directly observed medication adherence

    Number of doses observed and reviewed by nursing staff compare to number of prescribed doses per day

    Time frame: 1 weeks

  3. Late Acute Rejection

    Number of biopsy-proven rejection, clinician-assigned rejection

    Time frame: 6 months post-intervention

  4. Hospitalization

    Number of hospitalizations

    Time frame: 6 months post-intervention

  5. Patient Activation Measure

    A 13-item scale designed to measure a patient's perception of their knowledge, skill and confidence in managing their chronic health condition

    Time frame: Pretest at enrollment and posttest at 12 weeks

  6. Patient Assessment of Chronic Illness Care (PACIC)

    A 20-item scale with five subscales (scale of 1 (none) to 5 (always), total score 20 to 200, higher score being better outcome) that assess patient activation, delivery system design, goal setting, problem-solving and contextual counseling, and follow-up and coordination.

    Time frame: Pretest at enrollment and posttest at 12 weeks

  7. Self-reported user satisfaction with the DOT app

    Collected using a modified version of the engagement index questionnaire used

    Time frame: Pretest at enrollment and posttest at 12 weeks

  8. Engagement metrics

    Standard engagement metrics or paradata (e.g., amount, frequency, duration, and depth of use)

    Time frame: Pretest at enrollment and posttest at 12 weeks

  9. PedsQL 3.0 Transplant Module (PedsQL-TM)

    HRQOL

    Time frame: Pretest at enrollment and posttest at 12 weeks

  10. Adolescent Medication Barriers Scale (AMBS)

    To assess adolescent perceived barriers to medication adherence

    Time frame: Pretest, posttest

  11. Parent Medication Barriers Scale (PMBS)

    To assess parental perceived barriers to their child taking their medication

    Time frame: Pretest at enrollment and posttest at 12 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2024 (actual). Primary completion is estimated for Feb 2027, 28 months after the start.

Of 425 non-industry interventional studies with no phase under Medication Adherence, half reached primary completion within 22 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 42. This study's planned 28 months is above that.

Counting every sponsor, half of 442 studies reached it within 21 months; a quarter within 11 and three quarters within 41.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 16, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
