Abstract
Accountable Care Units are a disruptive innovation that has moved care on acute care units from a traditional silo model, in which each discipline works separately from all others, to one in which multiple disciplines work together with patients and their families to move patients safely through their hospital stay. This article describes the "what," "how," and "why" of the Accountable Care Units model as it has evolved in different locations across a single health system and includes the lessons learned as different units and hospitals continue working to implement the model in their complex care environments.
