About this study
Official title: Pilot Test of Patient Decision Aid for Medication-Assisted Treatment for Opioid Use Disorder
The aims of the current study phase (R21) are: Aim 1. Develop a patient decision aid (PtDA-MAT) by incorporating best available scientific evidence on MAT as well as feedback from patients and clinical providers related to clinical priorities, perceived utility, and acceptability; Aim 2. Conduct pilot testing of the PtDA-MAT in an iterative process guided by an expert panel and involving key stakeholders (e.g., patients, physicians, policymakers) and field-testing.
Read the detailed description
In response to RFA-DA-18-005 (Expanding Medication Assisted Treatment for Opioid Use Disorders in the Context of the SAMHSA Opioid STR Grants, R21/R33), this project will develop and test a patient decision support tool called Patient Decision Aid for Medication-Assisted Treatment (PtDA-MAT) for use in the CA H\&SS. The PtDA-MAT is designed to (1) improve patient knowledge and involvement and to subsequently improve treatment adherence and outcomes and (2) to support clinicians in informing and communicating with their patients with OUD along a continuum of care. The project will conduct 1 year of R21 to develop and pilot-test the PtDA-MAT to facilitate shared decision making in CA H\&SS, followed by 3 years of R33 to assess the effectiveness of the PtDA-MAT in a randomized controlled trial.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Patient Decision AidBehavioural
PtDA-MAT will provide information on MAT treatment options and pros and cons of each treatment option, and will assess patients' preferred options.
| Study group | Role | What they receive |
|---|---|---|
| Patient Decision Aid | Experimental | Patients in this arm will receive Patient Decision Aid for Medication Assisted Treatment for opioid use disorder. Receives: Behavioral: Patient Decision Aid |
| Record-only control group | No intervention | Treatment records of patients receiving treatment in the same clinic in the prior 3 months will be abstracted for comparison purposes. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Treatment Retention
Treatment retention will be defined as number of days from initial treatment admission to either MAT discontinuation or most recent clinic visit followed by 2 months gap in treatment
Measured: 3 months
Secondary outcomes (2)
Drug screening results
Primarily opioid-negative urine testing (as collected by clinics as part of routine care) and other substance use per self-report (e.g., cannabis, benzodiazepines, cocaine, amphetamines)
Measured: 3 month
Treatment Adherence
Treatment Adherence defined as proportion of clinic visits attended
Measured: 3 month

- Model description
- The Patient Decision Aid for Medication Assisted Therapy (PtDA-MAT) will be pilot-tested by patients and clinicians during actual visits with OUD patients to assess its acceptability and feasibility. We will track patients receiving PtDAT-MAT using their clinical and administration data over a 3-month period and compare outcomes to those of treatment admissions during the 3 months prior to the pilot testing to assess preliminary outcomes associated with PtDAT-MAT.

Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03394261, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2026; AzTrials last refreshed its copy on 7 Nov 2026.
