Regimen Education and Messaging in Diabetes (REMinD)

Not Applicable

Completed

• Conditions: Medication Adherence; Diabetes Mellitus, Type 2
• Interventions: Behavioral: UMS Strategy; Behavioral: SMS Text Messaging

• Registration Number: NCT03185741
• Lead Sponsor: Northwestern University

Brief Summary

The investigators will leverage increasingly available technologies to impart a Universal Medication Schedule (UMS) in primary care to help patients living with diabetes safely use and adhere to complex drug regimens. The UMS standardizes the prescribing and dispensing of medicine by using health literacy principles and more explicit times to describe when to take medicine (morning, noon, evening, bedtime). This eliminates variability found in the way prescriptions are written by physicians and transcribed by pharmacists onto drug bottle labels. The proposed intervention will standardize prescribing within an electronic health record (EHR) so all medication orders include UMS prescription instructions ('sigs') and patients receive a medication information sheet with their after-visit summaries. Additionally, to help patients remember when to take prescribed medicines we will link unidirectional short message service (SMS) text reminders to the EHR, delivering medication reminders to patients around UMS intervals.

1. Test the effectiveness of the UMS, and UMS + SMS text reminder strategies compared to usual care.

2. Determine if the effects of these UMS strategies vary by patients' literacy skills and language.

3. Using mixed methods, evaluate the fidelity of the two strategies and explore patient, staff, physician, and health system factors influencing the interventions.

4. Assess the costs required to deliver either intervention from a health system perspective.

Detailed Description

The investigators will leverage increasingly available technologies to impart a Universal Medication Schedule (UMS) in primary care to help patients living with diabetes safely use and adhere to complex drug regimens. The UMS standardizes the prescribing and dispensing of medicine by using health literacy principles and more explicit times to describe when to take medicine (morning, noon, evening, bedtime). This eliminates variability found in the way prescriptions are written by physicians and transcribed by pharmacists onto drug bottle labels. The proposed intervention will standardize prescribing within an electronic health record (EHR) so all medication orders include UMS prescription instructions ('sigs') and patients receive a medication information sheet with their after-visit summaries. Additionally, to help patients remember when to take prescribed medicines we will link unidirectional short message service (SMS) text reminders to the EHR, delivering medication reminders to patients around UMS intervals.

The investigators will conduct a 3-arm, multi-site trial to test the effectiveness of the UMS, and UMS + SMS text reminder strategies compared to usual care. The investigators will enroll a total of 900 English and Spanish-speaking patients with poorly controlled type 2 diabetes mellitus. Enrolled patients will complete follow-up interviews 3 and 6 months following their baseline interview.

The aims of the investigation are to:

1. Test the effectiveness of the UMS, and UMS + SMS text reminder strategies compared to usual care.

2. Determine if the effects of these UMS strategies vary by patients' literacy skills and language.

3. Using mixed methods, evaluate the fidelity of the two strategies and explore patient, staff, physician, and health system factors influencing the interventions.

4. Assess the costs required to deliver either intervention from a health system perspective.

Arm && Interventions

Group	Intervention	Description
UMS Strategy + SMS Text Messaging	UMS Strategy	In addition to the components from the UMS strategy arm, patients will receive daily text message reminders for 6 months.
UMS Strategy + SMS Text Messaging	SMS Text Messaging	In addition to the components from the UMS strategy arm, patients will receive daily text message reminders for 6 months.
UMS Strategy	UMS Strategy	Patients of providers randomized to the UMS arm will receive study-related educational tools at their primary care visit to support the understanding, regimen consolidation, and use of prescriptions. These materials will be generated within the electronic health record. 1. Prescription instructions will be adapted to the UMS format to establish four standard time intervals (morning, noon, evening, bedtime) for prescribing and dispensing of medicine. UMS instructions also use simplified text and numeric characters instead of words to detail dose. 2. Single-page, plain language medication information sheets with important medication-related information following health literacy best practices.

Primary Outcome Measures

Name	Time	Method
Medication Adherence: Pill Count	6 months after baseline	Adherence will be measured for each prescription medication using an objective pill count of the number of pills within each prescription bottle. The proportion of pills taken over pills prescribed (PT/PP) will be calculated for each medication at baseline and 6Month. Pills taken will be calculated by subtracting the number of pills from the total quantity prescribed. Pills prescribed will be calculated by multiplying the number of pills prescribed each day by the number of days since the medication was filled. A proportion of pills taken over pills prescribed (PT/PP) of 80% or more is considered adherent.

Secondary Outcome Measures

Name	Time	Method
Medication Adherence: 24-hour Recall	6 months after baseline	Adherence will be measured for each prescription medication using self-report of how many pills and how often each medicine was taken over the last 24 hours. Patients are asked to specify the amount taken (i.e. dose) and when taken (to determine frequency and interval between doses). A patient is considered adherent on a specific medication if they answered all correctly: 1.dose, 2.frequency, 3.interval between doses
Medication Adherence: ASK-12	6 months after baseline	Adherence will be measured by the ASK-12 Adherence Barrier Survey, a subjective assessment of general adherence behaviors and barriers to treatment adherence.; The ASK-12 is scored by summing the selected responses (with scores ranging from 12 to 60) with higher scores indicating greater barriers to adherence.
Treatment Knowledge	6 months after baseline	Identification of drug purpose
