About this study
Official title: Phenotyping Adherence Through Technology-Enabled Reports and Navigation: The PATTERN Study
This study is being conducted to adapt and pilot test a technology-enabled, primary care strategy for routinely monitoring medication use and adherence among older adults with multiple chronic conditions and polypharmacy.
Read the detailed description
Our study aims are to:
Aim 1: Adapt the PATTERN intervention for use in primary care using input from key stakeholders. During Aim 1, the Northwestern research team will solicit opinions from key informants (patients, clinicians, practice administrators) to ensure PATTERN meets the needs of primary care.
Aim 2: Assess the PATTERN intervention's feasibility and acceptability for use in primary care. During Aim 2, the investigators will conduct a 2-arm, patient-randomized controlled trial at a Northwestern Medicine primary care practice. Participants will be recruited and randomly assigned, using a random number generator application, to either the PATTERN intervention or usual care. Usual care refers to the normal standard clinical practices at the participating practice. Participants will be followed for 6 months.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
The PATTERN InterventionBehavioural
The intervention components include:
- An adherence assessment that requests patients to self-report via MyChart about their medication use. The assessment provides a link between the health center and the patient ahead of a regularly scheduled clinic visit.
- Care alert notifications directed to a nurse pool and/or member of the clinical care team when a medication adherence related problem is identified by the adherence assessment. The alert will also include the type of problem the patient is experiencing (cognitive, psychological, medical, regiment, social and/or economic). Once they receive these alerts, the care team can then activate appropriate staff and/or resources to respond.
| Study group | Role | What they receive |
|---|---|---|
| Usual Care | No intervention | Usual care includes: 1. The normal standard clinical practices at the participating practice. 2. No specific materials to promote PATTERN, and no additional materials that include adherence assessments or care alert notifications. |
| The PATTERN Intervention | Active comparator | The intervention components include:
1. An adherence assessment completed by participants ahead of a regularly scheduled clinic visit.
2. Care alert notifications directed to a nurse pool and/or member of the clinical care team. Receives: Behavioral: The PATTERN Intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
Medication Adherence
Participants' medication adherence will be measured at about 2-4 weeks after their clinic visit using a validated self-report measure: ASK-12. The 12-item measure assesses general medication attitudes and beliefs across three domains: 1) inconvenience/forgetfulness, 2) treatment beliefs, and 3) behaviors. Response options range from "Strongly Disagree" to "Strongly Agree". Scores can range from 12-60 with higher scores representing greater barriers to adherence.
Measured: About 2-4 Weeks
Secondary outcomes (1)
Fidelity
The investigators will examine participants' completion rates of the routine medication adherence assessment. This will be identified via the EHR.
Measured: By the scheduled clinic visit (baseline)
