The Pacific Southwest and Mountain Plains Addiction Technology Transfer Centers created a new product to assist behavioral health providers and peer support specialists that provide services to People with Substance Use Disorders (PWSUDs) using the telephone (mobile, landline, or internet phones). This document provides sample policies and recommended practices that behavioral health providers and peer support specialists can use and/or adapt to help guide the delivery of Audio-Only Telehealth (AOTs). Many behavioral health treatment and peer support experts predict that patients/clients/peers will receive services in a hybrid delivery mode (in-person, videoconferencing, and telephone) in the near future. As such, behavioral health providers and peer support specialists will need to expand their skills and competencies while agencies and/or organizations will need policies and practices in place to guide service delivery utilizing AOTs. This product can be used as a starting point to assist in the implementation of AOTs or to enhance current AOTs. Additional products, infographics with tips, and training events regarding AOTs will be coming soon.
