CHRP Program

What is CHRP?

The Coalition for Harm Reduction and Prevention (CHRP), pronounced "chirp," is an innovative Hub and Spoke model/intervention.

Although the Hub and Spoke model has been used successfully for opioid use disorder treatment, CHRP is pioneering its use for broader harm reduction and prevention efforts in rural settings!

The CHRP program is being developed in collaboration with a diverse network of community partners including a community advisory board (CAB) and interviews with rural providers and rural people who use substances. Together, we aim to identify barriers and facilitators to the adoption of prevention and harm reduction services and hub-and-spoke models. These insights will inform the design of the CHRP program, ensuring it effectively meets rural community needs.

What exactly is a Hub and Spoke model?

A Hub and Spoke model is a research study that brings together core expertise, resources, and administration in a central "Hub," which supports and coordinates multiple "Spoke" sites participating in research studies.
In the CHRP study, the University of Michigan/VA, Michigan State University, WMed (Western Michigan University School of Medicine) will serve as the "Hub" sites. The 16 rural-serving Michigan clinics that participate in CHRP activities are the "Spoke" sites.

Is CHRP a research study, a program, or both?

Great question! The answer is: Both!

The CHRP Program is an innovative intervention designed to bring harm reduction and prevention services to rural areas using the Hub and Spoke model. It’s being developed collaboratively with our community partners to address real-world rural barriers and needs.
The CHRP Study refers to the research process evaluating and informing the program, including gathering input from our community advisory board, conducting interviews, and assessing barriers and facilitators. The study’s findings directly shape the program itself, ensuring it is effective and responsive.

In short, the CHRP Study is the research that guides the development and evaluation of the CHRP Program, and the CHRP Program is the intervention being tested and refined through this study.

What is the CHRP Study Purpose?

Funded by the National Institutes of Health (NIH), the CHRP study will refine and test the CHRP program, a multi-component Hub and Spoke model designed to support the implementation of prevention and harm reduction services in rural-serving primary care, substance use, & mental health clinics.

Who will take part in the CHRP study?

Participants: 16 rural-serving clinics across Michigan (Spoke Clinics). These will be primary care, mental health or substance use clinics.
Timeline: Spoke Clinics enrolled in the CHRP study will begin collaborating with the CHRP team in 2027–2028. The intervention phase for each Spoke Clinic will last 6 months, followed by post-intervention assessments.

What support is provided to participating Spoke Clinics?

CHRP Hubs will provide centralized services and resources to participating Spoke Clinics. Examples include:

Dedicated CHRP Hub Champion (full-time CHRP team member) to provide individualized implementation guidance
Clinician and staff training via monthly virtual learning collaboratives
Brief tele-health delivered counseling to help patients reduce substance use risk
CHRP Service Navigator to help patients connect to substance-related, mental health and transportation services
Expertise from addiction care leaders at the University of Michigan, Michigan State University and Western Med hubs.
Stipend for clinic Spoke Champion after intervention phase
Clinic staff participants receive remuneration for CHRP study assessments

CHRP Program Goal

CHRP’s goal is to support rural-serving clinics in improving their prevention and risk reduction services, ultimately enhancing patient outcomes in communities at risk for substance use disorders.
