Trial Outcomes & Findings for Transplant Regimen Adherence for Kidney Recipients by Engaging Information Technologies: The TAKE IT Trial (NCT NCT03104868)

NCT ID: NCT03104868

Last Updated: 2024-09-19

Results Overview

An in-person pill count using established guidelines will be conducted. When in-person interviews are not possible, pill count will be done over the phone. Adherence will be assessed within drugs. The proportion of pills taken/pills prescribed will be calculated per medication. Patients will be considered non-adherent for a medication if this score is \<=80% and adherent if pills taken/pill prescribed\>80% (0=non-adherent, 1=adherent).

Measure
Usual Care
Patients in this group will receive the usual standard of care.
Intervention
Patients in this group will receive the Transplant regimen Adherence for Kidney recipients by Engaging Information Technologies (TAKE IT) strategy components. TAKE IT Strategy: The TAKE IT Strategy includes: 1. Programming the electronic health record (EHR) to organize/simplify daily regimen schedules and generate electronic, tangible, print, low literacy medication education materials at every clinical encounter. 2. Short Message Service (SMS) text-messaging to remind patients when to take all their medicine. 3. A web-based patient portal that requests patients to periodically report upon their medication use, providing a continuous link between the transplant center and patient beyond routine in-person visits. 4. EHR notifications directed to the transplant center nurse coordinator if an adherence-related problem is identified by the web-based portal assessment, who then can activate appropriate staff to respond.

PRIMARY outcome

Timeframe: 1 year - 1.5 years

Population: Analyses included a pill count collected at 1 year or at 1.5 years if a pill count was not collected at 1 year. Observations were excluded if: 1.Medications were not in pill form; 2.Participants couldn't provide accurate quantities on their bottles; 3.Missing Fill or Start Dates, 4.Participants started their medications that day; 5. Pro re nata (PRN) Medications.

An in-person pill count using established guidelines will be conducted. When in-person interviews are not possible, pill count will be done over the phone. Adherence will be assessed within drugs. The proportion of pills taken/pills prescribed will be calculated per medication. Patients will be considered non-adherent for a medication if this score is \<=80% and adherent if pills taken/pill prescribed\>80% (0=non-adherent, 1=adherent).

SECONDARY outcome

Timeframe: 1 year

Population: Observations were excluded if participants did not complete the 24-hour recall questions.

Patients are asked to self-report 1) proper dose (# pills), 2) spacing (hours between doses), 3) frequency (times per day), and 4) total pills/day for each prescribed medication over the last 24 hours. Responses are coded as correct or incorrect. Patients will be scored 'yes' if they have demonstrated proper use by correctly reporting all components of the medicine.

SECONDARY outcome

Timeframe: 1 year

Population: We discovered the wrong timepoint was used in the original analysis. Results were updated in March 2024.

The Ask-12 is a self-report scale that assesses general medication attitudes and beliefs. The scale consists of 12 items across three domains (inconvenience/forgetfulness, treatment beliefs, and behaviors), with responses ranging from "Strongly Disagree" to "Strongly Agree". Score can range from 12-60 with higher scores representing greater barriers to adherence.

SECONDARY outcome

Timeframe: Value at 2 years minus value at baseline

Population: Participants were analyzed if we were able to retrieve a baseline and 2 year eGFR value from the chart to calculate change. Results were updated in March 2024 after receiving additional data from Mayo Clinic.

Change in eGFR (estimated glomerular filtration rate), ml/min/1.73m\^2 over 2 years. Values were not adjusted for race.
