We aimed to identify variations in nitrous oxide (NO) procurement between Australian states and territories per public hospital bed by undertaking a cross-sectional analysis of NO procurement data for all Australian public hospitals from 1 January 2017 to 30 June 2022. Data were obtained from state and territory departments of health. All Australian public hospitals across six states and two territories were included. We obtained NO procurement data from Department of Health representatives from all states and territories, accounting for all 697 Australian public hospitals and four public dental hospitals. The main outcome measured in this study was NO procurement per public hospital bed by state or territory. Across the 5 years (1 January 2017 to 30 June 2022) an average of 242,054 (standard deviation (SD) 16,222) kg of NO, equivalent to 64,144 (4299) tonnes of carbon dioxide emissions (COe), were procured per annum. COe emissions from NO purchase varied more than threefold per public hospital bed between different states/territories (0.47-1.48 COe tonnes per hospital bed). There were significant variations in NO procurement between Australian states and territories when adjusted for public hospital bed numbers. Further analysis of this variation to determine cause and to guide mitigation interventions is therefore warranted.
我们旨在通过对 2017 年 1 月 1 日至 2022 年 6 月 30 日期间所有澳大利亚公立医院的一氧化二氮（NO）采购数据进行横断面分析，确定澳大利亚各州和地区每所公立医院的 NO 采购量差异。数据来自州和地区卫生部。本研究纳入了澳大利亚六个州和两个地区的所有公立医院。我们从所有州和地区的卫生部代表那里获得了 NO 采购数据，涵盖了所有 697 家澳大利亚公立医院和 4 家公立牙科医院。本研究的主要结果是按州或地区每所公立医院的 NO 采购量进行测量。在 5 年期间（2017 年 1 月 1 日至 2022 年 6 月 30 日），平均每年采购 242,054 公斤（标准差 16,222 公斤）一氧化二氮，相当于 64,144 吨二氧化碳排放量（COe）。不同州/地区每所公立医院的 NO 采购产生的 COe 排放量差异超过三倍（每所医院床 0.47-1.48 吨 COe）。在调整公立医院床位数量后，澳大利亚各州和地区之间的 NO 采购存在显著差异。因此，有必要进一步分析这种差异，以确定原因并指导缓解干预措施。
