SUPREME-DM (Diabetes Mellitis) Treatment Study

July 15, 2014 updated by: HealthPartners Institute

An Intervention to Feedback 'Early' Non-Adherence Data to ImproveCardiovascular Disease Risk Factor Outcomes in Patients With Diabetes

This multisite pragmatic clinical trial was designed to assess the effectiveness of a single scripted telephone call to diabetes patients who (a) were currently above recommended clinical goals for glucose, blood pressure, or lipids, and (b) had recently been prescribed a new medication for that specific clinical domain. The goals of the intervention were to improve primary adherence and persistence to the newly prescribed medication and to improve control of glucose, blood pressure, and lipids.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This randomized trial tested the hypothesis that a telephone contact with a patient recently prescribed a new medication for uncontrolled glycated hemoglobin (A1c), blood pressure, or low-density lipoprotein cholesterol would improve (a) primary medication adherence, (b) medication persistence, (c) medication possession ratio, and (d) A1c, blood pressure or low-density lipoprotein cholesterol control. This study was part of the larger Agency for Healthcare Research and Quality funded SUPREME-DM study. The clinical trial reported here was coordinated and led by HealthPartners Institute for Education and Research, while data collection was coordinated through Kaiser Permanente Northwest and analysis was conducted at Kaiser Permanente Colorado. The clinical intervention sites for this study included Kaiser Permanente Northern California, Group Health Cooperative, Marshfield Clinic, and Geisinger Clinic.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • At each clinical intervention site, study subjects were selected if they:

    • were age 18-75 years
    • met study criteria for diabetes mellitus before study enrollment
    • received clinical care at a designated clinic or medical center involved in this study for at least 15 months before enrollment
    • were prescribed a new class of medication (not filled in the past 180 days) for A1c, BP, or LDL that was uncontrolled at the time of medication prescription (A1c>=8%, systolic BP>= 140 mm Hg, or LDL >=100 mg/dL).

Exclusion Criteria:

  • Study subjects were excluded if they were younger than 18 years of age
  • Older than 75 years of age
  • Did not have evidence of diabetes mellitus prior to study enrollment

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Intervention phone call
The intervention arm consisted of one protocol-structured telephone call from an interventionist who was a nurse health manager (1 site), diabetes educator or diabetes educator trainee (1 site), or pharmacist (2 sites). Interventionists followed the same structured telephone interview protocol to ascertain whether the subject had started taking the new prescription. Those taking the new medication as prescribed received positive reinforcement. Those who either had not filled the prescription or were not taking the medication as directed, were asked about reasons for nonadherence and assisted in identifying and resolving barriers. The median call lasted < than 5 minutes, and up to 3 call attempts were made. Most intervention calls occurred within 2 to 6 weeks after the prescription date.
Behavioral: Intervention Phone Call
The intervention arm consisted of one protocol-structured telephone call from an interventionist who was a nurse health manager (1 site), diabetes educator or diabetes educator trainee (1 site), or pharmacist (2 sites). Interventionists followed the same structured telephone interview protocol to ascertain whether the subject had started taking the new prescription. Those taking the new medication as prescribed received positive reinforcement. Those who either had not filled the prescription or were not taking the medication as directed, were asked about reasons for nonadherence and assisted in identifying and resolving barriers. The median call lasted < than 5 minutes, and up to 3 call attempts were made. Most intervention calls occurred within 2 to 6 weeks after the prescription date.
NO_INTERVENTION: Control arm - usual care
Those in the control arm received usual care.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
60 day Medication Adherence
Time Frame: 60 days
In a pragmatic randomized trial, we randomly assigned 2,378 adults with diabetes mellitus who were recently prescribed a new class of medication for elevated glycated hemoglobin (A1c) >= 8%, blood pressure >= 140/90 mm Hg, or low-density lipoprotein cholesterol >=100 mg/dL, to receive (a) one scripted telephone call from a diabetes educator or clinical pharmacist to identify and address nonadherence to the new medication or (b) usual care. Hierarchical linear and logistic regression models were used to assess impact on (a) first medication fill within 60 days of prescription,
60 days
120 day medication adherence
Time Frame: 120 days
In a pragmatic randomized trial, we randomly assigned 2,378 adults with diabetes mellitus who were recently prescribed a new class of medication for elevated glycated hemoglobin (A1c) >= 8%, Blood pressure >= 140/90 mm Hg, or low-density lipoprotein cholesterol >=100 mg/dL, to receive (a) one scripted telephone call from a diabetes educator or clinical pharmacist to identify and address nonadherence to the new medication or (b) usual care. Hierarchical linear and logistic regression models were used to assess impact on (b) >=2 medication fills within 180 days of prescription,
120 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Composite Control Level of Blood pressure, A1c and/or LDL
Time Frame: 180 days
In a pragmatic randomized trial, we randomly assigned 2,378 adults with diabetes mellitus who were recently prescribed a new class of medication for elevated glycated hemoglobin (A1c) >= 8%, Blood pressure >= 140/90 mm Hg, or low-density lipoprotein cholesterol >=100 mg/dL, to receive (a) one scripted telephone call from a diabetes educator or clinical pharmacist to identify and address nonadherence to the new medication or (b) usual care. Hierarchical linear and logistic regression models were used to assess impact on (c) clinically significant improvement in a composite measure of A1c, Blood pressure, or low-density lipoprotein cholesterol
