Vertical vs Horizontal Implementation of O-TLM (037)

Study Information


The Texas Christian University (TCU) JCOIN Research Center is testing two different strategies to implement an Opioid Treatment Linkage Model (O-TLM). The model is designed to link individuals under community supervision with appropriate community-based treatment services. O-TLM seeks to improve interagency collaboration through staff training and cross-system data sharing.

The study examines how best to implement this model, by engaging 18 sites in Illinois, New Mexico, and Texas. In half of the sites, a “vertical implementation” approach will train all program personnel within each unit simultaneously. In the remaining sites, a “horizontal implementation” approach will train one “lead-off” unit, which will test and refine its procedures, and then it will train other units until the model is adopted agency-wide.

The goal of the study is to learn how best to implement new models of service delivery, and whether individual treatment outcomes vary depending on the model used.
