The Veterans' Sentinel Act aims to significantly improve the Department of Veterans Affairs' collection and analysis of data related to suicides and attempted suicides by veterans on VA property, mandating annual evaluations of statistical trends and prevention recommendations. A key provision establishes a working group within 90 days to collect and analyze comprehensive data on these "on-campus suicides," reviewing root cause analysis data and information from the Behavioral Health Autopsy Program , including family interviews, while also documenting data deficiencies. This working group is further tasked with considering and implementing improvements to the VA's data collection processes, such as modifying incident reports, creating specific fields for on-campus incidents, and developing a unified management system to consolidate data from various sources. It will communicate regularly with VA medical centers to coordinate efforts, and the Secretary must provide annual briefings to Congress on its progress. Upon the working group's conclusion (operating for two to five years), a detailed report outlining its effectiveness and recommendations for enhancing data collection and management must be submitted to Congress.
