About

This is a multi-center randomized controlled trial comparing the effectiveness of community health worker (CHW) vs. usual clinician support in helping chronically-ill patients with low socioeconomic status to improve their health outcomes.

Full description

Community Health Workers (CHWs) have the potential to improve chronic disease outcomes among patients with low socioeconomic status (SES). Yet, widespread use of CHWs has been hampered by lack of standardized, scalable and evidence-based models. Our community-academic-health system team used participatory action research with low-SES patients to design IMPaCT (Individualized Management for Patient-Centered Targets). A randomized controlled trial (RCT) of 446 hospitalized patients with varied diseases demonstrated that a 2-week dose of IMPaCT improved access to care, mental health, activation, and quality of communication, while reducing recurrent hospital readmissions. We have adapted IMPaCT for use among low-SES primary care patients with multiple chronic conditions.

This RCT is designed to evaluate the newly adapted IMPaCT model in 3 primary care settings - academic, federally qualified health center, and VA. Upon enrollment in the trial, patients will collaboratively set a chronic disease management goal with their primary care provider. Patients will then be randomized to collaborative goal-setting versus goal-setting augmented by 6 months of support from an IMPaCT CHW. Follow-up will be conducted at 6- and 9- months post-enrollment.

The study design is a single-blinded, 2- armed, multi-site randomized controlled trial involving three clinic sites and 444 patients.

Trial design

Primary purpose: Health Services Research

Allocation: Randomized

Interventional model: Single Group Assignment

Masking: Single Blind

---

592 participants in 2 patient groups, including a placebo group

Usual clinician support

Placebo Comparator group

Description:

Prior to randomization, patients in this arm will already have set a chronic disease management goal with their primary care provider (who will have received training in collaborative goal-setting). After randomization, patients in the usual clinician support arm will receive usual care in accordance with guidelines at each site.

Treatment:

Other: Usual care

CHW support

Experimental group

Description:

Prior to randomization, patients in this arm will already have set a chronic disease management goal with their primary care provider (who will have received training in collaborative goal-setting). After randomization, patients in the CHW arm will receive the IMPaCT intervention.

Treatment:

Behavioral: IMPaCT
