Supervised injecting facilities (SIFs) are effective in reducing the harms associated with injecting drug use among their clientele, but do SIFs ease the burden on ambulance services of attending to overdoses in the community? This study addresses this question, which is yet to be answered, in the growing body of international evidence supporting SIFs efficacy.
Ecological study of patterns in ambulance attendances at opioid-related overdoses, before and after the opening of a SIF in Sydney, Australia.
A SIF opened as a pilot in Sydney's 'red light' district with the aim of accommodating a high throughput of injecting drug users (IDUs) for supervised injecting episodes, recovery and the management of overdoses.
A total of 20,409 ambulance attendances at opioid-related overdoses before and after the opening of the Sydney SIF. Average monthly ambulance attendances at suspected opioid-related overdoses, before (36 months) and after (60 months) the opening of the Sydney Medically Supervised Injecting Centre (MSIC), in the vicinity of the centre and in the rest of New South Wales (NSW).
The burden on ambulance services of attending to opioid-related overdoses declined significantly in the vicinity of the Sydney SIF after it opened, compared to the rest of NSW. This effect was greatest during operating hours and in the immediate MSIC area, suggesting that SIFs may be most effective in reducing the impact of opioid-related overdose in their immediate vicinity.
By providing environments in which IDUs receive supervised injection and overdose management and education SIF can reduce the demand for ambulance services, thereby freeing them to attend other medical emergencies within the community.
监督注射设施（SIF）在减少其服务对象与注射吸毒相关的危害方面非常有效，但 SIF 是否减轻了救护车服务机构应对社区中过量用药的负担？本研究针对这一问题，该问题在支持 SIF 有效性的国际证据不断增加的情况下尚未得到解答。
在澳大利亚悉尼开设 SIF 前后，对与阿片类药物相关的过量用药的救护车出勤模式进行的生态研究。
SIF 作为试点在悉尼的“红灯区”开设，目的是为大量接受监督注射的吸毒者（IDU）提供注射场所、康复和管理过量用药。
在悉尼 SIF 开设前后，共发生 20409 例与阿片类药物相关的过量用药救护车出勤事件。在悉尼医疗监督注射中心（MSIC）附近和新南威尔士州（NSW）其他地区，在 MSIC 开设之前（36 个月）和之后（60 个月），每月与疑似阿片类药物相关的过量用药救护车出勤的平均次数。
与新南威尔士州其他地区相比，在悉尼 SIF 开设后，该中心附近救护车服务机构应对与阿片类药物相关的过量用药的负担显著下降。这种影响在营业时间和 MSIC 区域内最大，表明 SIF 可能在减少其附近地区与阿片类药物相关的过量用药影响方面最为有效。
通过提供 IDU 接受监督注射和管理和教育的环境，SIF 可以减少对救护车服务的需求，从而使他们能够在社区内应对其他医疗紧急情况。
