Using and sharing data to provide the appropriate response to high utilizers’ needs is challenging work, but it results in meaningful outcomes for individuals, families, and the community. Effective use of data can also reduce the number of individuals held in jail pretrial simply because they cannot afford bail, reduce recidivism, and help develop better programs for individuals with mental health and substance use disorders. Creating a network for information sharing and engaging in effective planning and coordination is critical to building a consensus around which data can and will be shared. Key stakeholders must understand the legal framework for information sharing to design and implement effective criminal justice and health and human services collaborations. Staff members must be trained to respond to questions about the purpose and limits of data sharing.
