- Brief Summary
Liver transplantation is increasingly performed for older adults with multiple comorbidities. Medication adherence is key to maintaining proper function of the transplanted liver and optimize health; however, adhering to post-transplant treatment is complex. This trial will study how available technology combined with transplant center resources and caregiver support can optimize medication adherence, quality of life, and health outcomes among new liver transplant recipients at 3 centers.
- Detailed Description
Liver transplant, the only cure for end-stage liver disease, is a costly and limited resource that increases survival. It is increasingly performed among older adults who have a higher burden of comorbidities, medical complexity, and are at risk of non-adherence. In addition, liver transplant recipients must manage complex immunosuppression regimens to maintain graft function. Inadequate immunosuppression adherence is common post-liver transplant and has many adverse consequences including liver graft rejection, graft failure, and re-transplantation. To maintain their health, liver transplant recipients must also self-manage regimens for multiple chronic conditions beyond liver transplant.
The TEST Trial intervention is a conceptual framework to address health system and patient level barriers to adherence. By following the Cumulative Complexity Model and the Multiple Chronic Conditions Model, this study focuses on liver transplant recipients and their involved caregivers. The TEST trial leverages the use of electronic health record and Way to Health (W2H) text message system to improve medication adherence.
TEST is a 2-arm, patient-randomized controlled trial at three large, diverse transplant centers: University of Pennsylvania (UPENN), Northwestern University (NU); University of Miami (UM). A total of 360 de novo LTRs age 50 or older (n=180 per arm) within 3 months of transplant will be recruited and randomized to intervention versus usual care for 18 months. Interviews will be conducted at baseline, 6, 12, and 18 months. The TEST intervention includes:
* Monthly W2H Adherence Assessment \& Clinician Alerts
* Medication Reminders
* Laboratory and Appointment Notifications
* Supplemental Self-Management Support
The primary objective of the study is to investigate the effectiveness of the TEST Trial to improve adherence to immunosuppressant and non-immunosuppressant medication regimens, functional health status, and health outcomes compared to usual care. Secondary objectives will measure study fidelity and cost effectiveness.

Group Intervention Description TEST Intervention TEST Intervention Clinical activities for Usual Care will also be provided in the TEST arm. The TEST intervention is a technology-enabled strategy to routinely monitor regimen use, adherence, and persistence via a 'low touch', easy to use, online behavioral toolkit - Way to Health . It was developed by University of Pennsylvania researchers to automate behavioral intervention. The TEST approach includes monthly adherence assessments, with tailored adherence support. The following components will be included in the intervention: * Monthly W2H Adherence Assessment \& Clinician Alerts * Medication Reminders * Laboratory and Appointment Notifications * Supplemental Self-Management Support
- Primary Outcome Measures
Name Time Method 24 Hour Recall 18 Months Patient self-report of how many pills and how often each medicine was taken over the last 24 hours. Patients will also be asked about the medical indication for each drug. Correct dosing will be measured as a yes/no per drug, having properly shown dose (number of pills), spacing (hours between doses), frequency (times per day), and total pills/day.
- Secondary Outcome Measures
Name Time Method Liver Graft Outcomes 18 Months The number of instances of liver graft rejection and liver graft failure post-transplant
EQ-5D-5L 18 Months Patient health outcomes will be measured using the EQ-5D-5L questionnaire. This tool measures mobility, self-care, usual activities, pain/discomfort, anxiety/depression, and self-rated health. Each dimension has 5 levels: no problem, sight problems, moderate problems, severe problems, and extreme problems. Patient choice for each results in a 1-digit number that expresses the level selected, and the digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. A lower score indicates a good health state while a higher score represents a more severe health state. In addition, there is a visual analogue scale (VAS) to indicate the general health status with 100 indicating the best health status and 0 being the worst health state
Post-Transplant Infection 18 Months The number of instances of patient having an infection (bacterial, viral, or fungal) post-transplant
ASK-12 18 Months The ASK-12 is a self-report scale that assess general medication attitudes and beliefs. The scale consists of 12 items across three domains (inconvenience/forgetfulness, treatment beliefs, and behaviors), with responses ranging from "Strong Disagree" to "Strongly Agree". The score can range from 12-60 with higher scores representing greater barriers to adherence.
Balance Test, seconds 18 Months The Balance Test is a measure of balance in participants. The patient is asked to hold three poses for up to 10 seconds: a side-by-side stand, a semi-tandem stand, and a tandem stand. The patient must be able to stand unassisted without the use of a cane or walker. The test administrator will count up to 10 seconds and record the time if the participant is not able to hold the pose for the full amount. Participants are given one point for each pose that they can hold for 10 seconds. Individuals with a lower amount of points have poorer balance and are deemed at great risk for falls.
Liver Frailty Index 18 Months The Liver Frailty Index (LFI) is a calculated measurement from the results obtained in the 30-second chair stand, balance test, and grip strength assessments. The LFI measurement is on a scale of 0-10 with 0 being the most healthy and robust and 10 being the most frail. This value is calculated using a normative sample of 1405 outpatients with cirrhosis awaiting liver transplantation.
Mortality 18 Months If a patient passes away in the study, the date of death and cause of death will be recorded along with the number of days death occurred post-transplant
Tacrolimus Lab Values, ng/mL 18 Months Tacrolimus lab values (ng/mL) will be tracked. Patient immunosuppression variability will be assessed with the tacrolimus coefficient of variation (COV) (100 x standard deviation/mean tacrolimus concentration) and the medication level variability index (MLVI, standard deviation of at least three values. The range for COV is 0-1 , and the MLVI range generally falls between 0-9. Nonadherence to medication can be seen in values \>= 0.30 for COV and greater than 2.5-2.6 for MLVI.
Fidelity will be measured through the number of completed monthly assessments, patient/caregiver engagement with text messages, and percent care alerts with clinical actions taken.Alcohol, Tobacco, and Drugs Survey 18 Months Health-related quality of life (HRQOL) will be measured in part by the Alcohol, Tobacco, and Drugs Survey. This is a questionnaire asking participants about their recent alcohol, drug, and tobacco use. The questions related to alcohol use are adapted from the AUDIT-C form. The tobacco and marijuana sections ask participants about their current and past smoking habits as well as the type of tobacco and marijuana they used. Those regarding alcohol assess the frequency of drinking and the quantity of drinks per drinking sessions.
30-Second Chair Stand, seconds 18 Months The 30-Second Chair Stand test is a measure of leg strength and endurance. The patient is asked to move from a seated position with arms crossed over the into the standing position and then sit back down. The test administrator counts the number of times the patient comes to a full standing position in 30 seconds. The number of successful completions indicates the risk of fall. This score is dependent on age category with \<14 for men and \<12 for women between the age of 60-64 indicating a greater risk for all
Grip Strength, pounds 18 Months Grip strength is a measure of muscular strength or the maximum force/tension generated by one's forearm muscles. It is measured in pounds. Participants are asked to squeeze a hand dynamometer as hard as possible for five seconds until a maximum number of pounds is reached. The test administrator records this maximum value and asks the participant to repeat the exercise two more times with a five second break in between. The three maximum values are averaged to obtain a final score. The lower the final score, the lower a persons grip strength is and thus their probability of physical frailty.
Days Alive Out of Hospital 18 Months The number of days a patient spends alive and not hospitalized for any reason
