National Preparedness for 988

988, a national mental health emergency hotline number, went live throughout the United States in July 2022. 988 connects callers to the 988 Crisis & Suicide Lifeline, previously known as the National Suicide Prevention Lifeline. The transition to the three-digit number aimed to respond to a growing national mental health crisis and to expand access to crisis care. We examined preparedness throughout the U.S. for the transition to 988. In February and March 2022, we administered a national survey of state, regional, and county behavioral health program directors. Respondents (n=180) represented jurisdictional coverage of 120 million Americans. We found that communities throughout the U.S. appeared ill-prepared for rollout of 988. Fewer than half of respondents reported their jurisdictions were 'somewhat' or 'very' prepared for 988 in terms of financing (29%), staffing (41%), infrastructure (41%), or service coordination (47%). Counties with higher representation of Hispanic/Latinx individuals were less likely to report being prepared for 988 in terms of staffing (OR: 0.62, 95 %CI: 0.45, 0.86) and infrastructure (OR: 0.68, 95 %CI: 0.48, 0.98). In terms of existing services, sixty percent of respondents reported a shortage of crisis beds and fewer than half reported availability of short-term crisis stabilization programs in their jurisdictions. Our study highlights components of local, regional, and state behavioral health systems in the U.S. that require greater investments to support 988 and mental health crisis care.
