Australian harm reduction services are provided via a mix of modalities, including fixed-site needle and syringe programmes (NSP) and syringe-dispensing machines (SDMs). SDMs are cost-effective and provide 24-h anonymous access to needles/syringes, often to underserved geographic areas, and can attract clientele who may choose not to use NSPs. The introduction of COVID-19 control measures saw disruptions and adaptations to the provision of harm reduction services. It is possible that SDMs filled the gap in otherwise disrupted harm reduction services in Melbourne. In this paper, we use data from four SDMs and an NSP to explore changes to harm reduction usage during periods of COVID-19 lockdowns in Melbourne, Australia, in 2020.
Our data span September 2017-December 2020. We analysed daily counts of SDM use and monthly counts of NSP use, according to unique presentations to both. Auto-regressive integrated moving average (ARIMA) time-series models were fitted to the data with the effects of lockdowns estimated via a step function.
Across the study period, we estimated 85,851 SDM presentations and 29,051 NSP presentations. Usage across both the SDMs and the NSP declined during the COVID-19 lockdowns, but only the decline in SDM usage was significant in ARIMA analysis.
The slight, but significant decline in SDM use suggests barriers to access, though this may have been mitigated by SDM users acquiring needles/syringes from other sources. The decline, however, may be a concern if it led to lowered needle/syringe coverage and a subsequent increase in injecting risk. Further work is needed to properly explore potential changes in preference for needle/syringe acquisition site and associated barriers. Importantly, this work adds to the body of literature around the impacts of COVID-19 on harm reduction provision and potential areas of improvement.
澳大利亚的减少伤害服务通过多种模式提供,包括固定地点的针具和注射器方案(NSP)和注射器分发机(SDM)。SDM 具有成本效益,可以提供 24 小时匿名获取针头/注射器的途径,通常针对服务不足的地理区域,并且可以吸引可能选择不使用 NSP 的客户。引入 COVID-19 控制措施后,减少伤害服务的提供发生了中断和调整。在墨尔本,SDM 可能填补了中断的减少伤害服务的空白。在本文中,我们使用来自四个 SDM 和一个 NSP 的数据,探索了澳大利亚墨尔本 2020 年 COVID-19 封锁期间减少伤害使用的变化。
我们的数据跨越 2017 年 9 月至 2020 年 12 月。我们根据两者的独特呈现,分析了 SDM 使用的每日计数和 NSP 使用的每月计数。自动回归积分移动平均(ARIMA)时间序列模型拟合到数据中,封锁的影响通过阶跃函数进行估计。
在整个研究期间,我们估计有 85851 次 SDM 呈现和 29051 次 NSP 呈现。在 COVID-19 封锁期间,SDM 和 NSP 的使用都有所下降,但只有 SDM 使用的下降在 ARIMA 分析中具有统计学意义。
SDM 使用量略有下降,但具有统计学意义,表明存在获取障碍,尽管这可能通过 SDM 用户从其他来源获取针头/注射器而得到缓解。然而,如果这导致针头/注射器覆盖率降低和随后的注射风险增加,这种下降可能令人担忧。需要进一步的工作来正确探索对针头/注射器获取地点的偏好变化和相关障碍的潜在变化。重要的是,这项工作增加了关于 COVID-19 对减少伤害服务提供的影响和潜在改进领域的文献。
