The EPIS Framework

The CEBC has adopted the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework as the basis for its implementation work. The EPIS framework was developed by CEBC-affiliated implementation scientists at the Child and Adolescent Services Research Center (CASRC) through funding from the National Institute of Mental Health (NIMH)(Aarons, Hurlburt, & Horwitz, 2011; see below for link to article). It is based on existing research on implementation and was developed specifically for use in child welfare and similar service sectors.

Article summary: Implementation science is a quickly growing discipline. Lessons learned from business and medical settings are being applied but it is unclear how well they translate to settings with different historical origins and customs (e.g., public mental health, social service, alcohol/drug sectors). This paper describes the multilevel, four phase EPIS (Exploration, Preparation, Implementation, Sustainment) model of the implementation process, derived from existing literature, and applies it to public sector services. The paper highlights features of the model likely to be particularly important in each phase, while considering the outer and inner contexts of public sector service systems.
