Abstract

Background: Despite its essential and life-saving role in the treatment of many medical conditions, access to medical oxygen remains limited in many countries. In 2021, Partners In Health established an oxygen distribution network in Lesotho to increase medical oxygen access.

Methods: We conducted an observational study reporting on the design, implementation, and outcomes of a national oxygen distribution network in Lesotho from November 2022 through January 2024. Oxygen delivery data were abstracted from tracking logs and analysed in Stata. Continuous and ordinal variables were summarised by medians and ranges. Categorical variables were described using frequencies and proportions.

Results: Over the 15 month study period, the network expanded from one oxygen production hub serving five recipients to four hubs and 21 recipients located across nine of Lesotho's 10 districts. The network delivered 1565 filled cylinders containing 9619.23 m3 oxygen, enough to treat 601 patients. For the 13 recipients with inpatient beds, the median monthly volume of oxygen delivered per bed was 1.43 m3 (IQR: 0.57 to 2.31).

Conclusion: This study demonstrates the feasibility of an oxygen distribution network in Lesotho, providing proof-of-concept for an intervention to improve oxygen access in low- and middle-income countries. By employing real-time monitoring and redundant sourcing, the network provided a reliable oxygen supply responsive to variations in demand and periods of oxygen plant downtime. This study also provides insights into facility-level oxygen consumption, which may help policymakers improve quantification and prediction of oxygen demand. Future efforts should focus on enhancing data collection, characterising oxygen usage and strengthening infrastructure to promote sustainable oxygen security.

莱索托全国氧气配送网络的设计、实施和成果。
背景:尽管医用氧气在许多疾病的治疗中起着至关重要的救生作用,但在许多国家,医用氧气的供应仍然有限。2021 年,健康伙伴组织在莱索托建立了一个氧气配送网络,以增加医用氧气的供应:我们开展了一项观察性研究,报告了 2022 年 11 月至 2024 年 1 月期间莱索托全国氧气配送网络的设计、实施和成果。氧气配送数据摘自追踪日志,并在 Stata 中进行分析。连续变量和顺序变量用中位数和范围进行总结。分类变量采用频率和比例进行描述:在为期 15 个月的研究期间,该网络从一个氧气生产中心为 5 名受援者提供服务扩展到四个中心和 21 名受援者,分布在莱索托 10 个区中的 9 个区。该网络提供了 1565 个装满氧气的气瓶,内含 9619.23 立方米氧气,足以治疗 601 名病人。在拥有住院床位的 13 个接收方中,每张床位的每月氧气输送量中位数为 1.43 立方米(IQR:0.57 至 2.31):这项研究证明了在莱索托建立氧气配送网络的可行性,为改善中低收入国家的氧气供应提供了概念验证。通过采用实时监控和冗余来源,该网络提供了可靠的氧气供应,可应对需求变化和制氧厂停工期。这项研究还提供了对设施一级耗氧量的深入了解,这可能有助于政策制定者改进对氧气需求的量化和预测。今后的工作重点应放在加强数据收集、描述氧气使用情况和加强基础设施建设上,以促进可持续的氧气安全。

期刊介绍: BMJ Global Health is an online Open Access journal from BMJ that focuses on publishing high-quality peer-reviewed content pertinent to individuals engaged in global health, including policy makers, funders, researchers, clinicians, and frontline healthcare workers. The journal encompasses all facets of global health, with a special emphasis on submissions addressing underfunded areas such as non-communicable diseases (NCDs). It welcomes research across all study phases and designs, from study protocols to phase I trials to meta-analyses, including small or specialized studies. The journal also encourages opinionated discussions on controversial topics.
