The Road to 988/911 Interoperability: Three Case Studies on Call Transfer, Colocation, and Community Response.

The 988 Suicide and Crisis Lifeline-known more simply as 988-holds promise for significantly improving the mental health of Americans and accelerating the decriminalization of mental illness. However, the rapid transition to 988 has left many gaps as communities scramble to prepare-not the least of which includes determining how 988 will interface with local 911 response systems and law enforcement. 911 is often the default option for individuals experiencing mental health emergencies, despite the fact that 911 call centers have limited resources to address behavioral health crises. Since 988 launched in 2022, one key area of focus has been ways that jurisdictions approach 988/911 interoperability: the existence of formal protocols, procedures, or agreements that allow for the transfer of calls from 988 to 911 and vice versa. This study presents case studies from three jurisdictions that have established models of 988/911 interoperability. It provides details related to interoperability in each model, including the role of each agency, points of interagency communication, and decision points that can affect the way a call flows through the local system. It also identifies facilitators, barriers, and equity-related considerations of each jurisdiction's approach, as well as lessons learned from implementation. This study should be of interest to jurisdictions that are looking to implement 988/911 interoperability, including those that are spearheading local initiatives and those that are responding to state-level legislation. Its findings are relevant to 988 call centers, public safety answering points, mobile crisis units, law enforcement, and local and state decisionmakers.
