Brief Summary

A large body of research has demonstrated that intensive lifestyle interventions and metformin are effective treatments to prevent or delay diabetes among high-risk adults, yet neither treatment is routinely used in practice. This pilot study will develop and evaluate the Diabetes Risk Education and Communication Trial (DiRECT) intervention, which communicates information about diabetes risk and treatment options for preventing diabetes among primary care patients with prediabetes. Given that 38% of U.S. adults have prediabetes, this project has large potential to impact public health by developing a scalable intervention to promote the use of evidence-based treatments that lower diabetes risk in this population.

Outcome Measures

Primary Outcomes (1)

  • Intent to treat questionnaire: Participant initiation of treatment to intensive lifestyle (ILI) or Metformin

    The number of participants that initiate ILI, Metformin, or both treatments at follow-up is the primary outcome of the pilot trial, which will be assessed in the following ways. Because initiation of metformin requires a provider prescription, this will be assessed pragmatically using the electronic health record (EHR) and confirmed by participant self-report of taking at least 1 dose. Attendance logs will be used to confirm whether participants attended at least 1 ILI session. Those who received a prescription for metformin but do not take any doses will not be considered to have initiated treatment. Similarly, those who are referred to ILI but do not attend any sessions will not be classified as initiating treatment. Receiving a provider's prescription for metformin or referral for ILI without initiating treatment will be an exploratory outcome.

Study Arms (2)

DiRECT

EXPERIMENTAL

DiRECT consists of the following components that will be delivered by medical assistants before patients' routinely scheduled office visits: 1) a prediabetes decision aid focused on type 2 diabetes (T2D) risk and treatment options for preventing T2D; 2) a 'think aloud' exercise; and 3) formulating a preliminary treatment plan for T2D prevention.

Behavioral: DiRECT

Usual Care (UC)

ACTIVE COMPARATOR

Participants randomized to standard care will receive routine medical care without the medical assistant delivered DiRECT intervention.

Behavioral: Usual care (UC)

Interventions

DiRECTBEHAVIORAL

DiRECT participants will meet with a medical assistant (MA) before a routinely scheduled office and formulate a preliminary treatment plan for T2D prevention. Participants will attend their scheduled physician visit, during which they may make a definitive treatment plan to initiate metformin and/or ILI.
