本研究利用瑞士1998-2022年各城市DCR分阶段引入的准自然实验，通过双重差分法发现DCR开放使5公里内毒品相关住院率降低约35%，其中致命结果下降35%，支持DCR作为有效减少伤害策略。
AI 中文摘要
本文估计了毒品消费室（DCR）开放对瑞士毒品相关住院的因果效应。我利用1998年至2022年间瑞士各城市DCR的分阶段引入，使用个体层面的医院记录和双重差分估计器。DCR的开放使设施5公里范围内的毒品相关住院率降低了约35%。这种减少在致命结果中最为显著，致命结果下降了35%，而麻醉品中毒住院则上升了相当的数量，这与DCR将可能致命的过量用药转化为非致命住院相一致。精神和行为障碍住院下降了32%，而肝炎和HIV的估计则不精确。这些发现支持DCR作为有效减少伤害策略的作用。
英文摘要
This paper estimates the causal effect of drug consumption room (DCR) openings on drug-related hospitalizations in Switzerland. I exploit the staggered introduction of DCRs across Swiss cities between 1998 and 2022, using individual-level hospital records and a difference-in-differences estimator. DCR openings reduce drug-related hospitalization rates by roughly 35\% within 5 km of a facility. The reduction is most pronounced for fatal outcomes, which fall by 35\% while narcotics poisoning hospitalizations rise by a comparable amount, consistent with DCRs converting potentially fatal overdoses into non-fatal hospitalizations. Mental and behavioral disorder hospitalizations decline by 32\% while estimates for Hepatitis and HIV are imprecise. The findings support the role of DCRs as an effective harm reduction strategy.
