The Garrett Lee Smith (GLS) Memorial Act, continuously funded since 2004, has supported comprehensive, community-based youth suicide prevention efforts throughout the United States. Compared to matched communities, communities implementing GLS suicide prevention activities have lower population rates of suicide attempts and lower mortality among young people. Positive outcomes have been more pronounced with continuous years of implementation and in less densely populated communities. Cost analyses indicate that implementation of GLS suicide prevention activities more than pays for itself in reduced health care costs associated with fewer emergency department visits and hospitalizations. Although findings are encouraging, the heterogeneity of community suicide prevention programs and the lack of randomized trials preclude definitive determination of causal effects associated with GLS. The GLS initiative has never been brought fully to scale (e.g., simultaneously impacting all communities in the United States), so beneficial effects on nationwide suicide rates have not been realized.

Garrett Lee Smith 纪念法案：预防自杀倡议的描述和回顾


自 2004 年以来持续资助的 Garrett Lee Smith （GLS） 纪念法案支持了美国各地以社区为基础的全面青少年自杀预防工作。与匹配的社区相比，实施 GLS 自杀预防活动的社区自杀未遂的人口率较低，年轻人的死亡率较低。随着连续多年的实施和人口密度较低的社区，积极成果更加明显。成本分析表明，实施 GLS 自杀预防活动在降低与减少急诊就诊和住院相关的医疗保健成本方面物超所值。尽管研究结果令人鼓舞，但社区自杀预防计划的异质性和随机试验的缺乏排除了对与 GLS 相关的因果效应的明确确定。GLS 计划从未完全规模化（例如，同时影响美国的所有社区），因此尚未实现对全国自杀率的有益影响。
