Medical oxygen services are essential for the care of acutely unwell patients. We aimed to assess the effects of a multilevel, multicomponent health-system intervention on hypoxaemia detection, oxygen therapy, and mortality among neonates and children attending level IV health centres and hospitals in Uganda.
For this before-after intervention study, we included children who attended paediatric or neonatal wards of 24 level IV health centres and seven general or regional referral hospitals in the Busoga and North Buganda regions of Uganda between June 1, 2020, and June 30, 2022. All neonates younger than 1 month and children aged 1 month to 14 years were eligible for inclusion. We excluded neonates who were not sick but stayed in the maternity ward for routine postnatal care. The intervention involved clinical training, mentorship, and supportive supervision; provision of pulse oximeters and cylinder-based oxygen sources; biomedical-capacity support; and support to develop and disseminate oxygen supply strategies, oxygen therapy guidelines, and lists of essential oxygen supplies. Trained research assistants extracted individual patient data from case notes using a standardised electronic data collection form. Data were collected on health-facility details, age, sex, clinical signs and symptoms, admission diagnoses, pulse oximetry readings, oxygen therapy details, and final patient outcome. The primary outcome was the proportion of admitted neonates and children with a pulse oximetry oxygen saturation reading documented in their patient case notes on day 1 of health-facility admission (ie, pulse oximetry coverage). We used mixed-effects logistic regression to evaluate the effect of the intervention.
We obtained data on 71 997 eligible neonates and children admitted to 31 participating health facilities; the primary analysis included 10 001 patients in the pre-intervention period (ie, June 1 to Oct 30, 2020) and 51 329 patients in the post-intervention period (ie, March 1, 2021, to June 30, 2022). Because 1356 patients had missing data for sex, 4365 (46·7%) of 9347 in the pre-intervention group and 22 831 (46·2%) of 49 410 in the post-intervention group were female; 4982 (53·3%) in the pre-intervention group and 26 579 (53·8%) in the post-intervention group were male. The proportion of neonates and children with pulse oximetry at admission increased from 2365 (23·7%) of 10 001 in the pre-intervention period to 45 029 (87·7%) of 51 328 in the post-intervention period. Adjusted analysis indicated greater likelihood of a patient receiving pulse oximetry during the post-intervention period compared with the pre-intervention period (adjusted odds ratio 40·10, 95% CI 37·38-42·93; p<0·0001).
Large-scale improvements in hospital oxygen services are achievable and have the potential to improve clinical outcomes. Governments should be encouraged to develop national oxygen plans and focus investment on interventions that have been shown to be effective, including the introduction of pulse oximetry into routine hospital care and clinical and biomedical mentoring and support.

医用氧气服务对于急性不适患者的护理至关重要。我们旨在评估一项多层次、多组成的卫生系统干预措施对乌干达四级卫生中心和医院就诊的新生儿和儿童的低氧血症检测、氧疗和死亡率的影响。
在这项前后干预研究中,我们纳入了 2020 年 6 月 1 日至 2022 年 6 月 30 日期间在乌干达布萨加和北布干达地区的 24 个四级卫生中心和 7 个普通或区域转诊医院的儿科或新生儿病房就诊的儿童。所有年龄在 1 个月以下的新生儿和 1 至 14 岁的儿童都有资格入组。我们排除了那些没有生病但因常规产后护理而留在产科病房的新生儿。干预措施包括临床培训、指导和支持性监督;提供脉搏血氧仪和基于气瓶的氧气源;生物医学能力支持;以及支持制定和传播氧气供应策略、氧疗指南和基本氧气供应清单。经过培训的研究助理使用标准化电子数据采集表从病历中提取患者的个体数据。数据收集内容包括医疗机构的详细信息、年龄、性别、临床症状和体征、入院诊断、脉搏血氧仪读数、氧疗细节和最终患者结局。主要结局是在医疗机构入院第一天(即脉搏血氧仪覆盖率)记录在患者病历中的入院新生儿和儿童的比例。我们使用混合效应逻辑回归来评估干预的效果。
我们获得了 31 家参与医疗机构的 71997 名合格新生儿和儿童的数据;主要分析包括干预前期间的 10001 名患者(即 2020 年 6 月 1 日至 10 月 30 日)和干预后期间的 51329 名患者(即 2021 年 3 月 1 日至 2022 年 6 月 30 日)。由于 1356 名患者的性别数据缺失,因此在干预前组中,有 4365(46.7%)名患者和在干预后组中,有 22831(46.2%)名患者为女性;在干预前组中,有 4982(53.3%)名患者和在干预后组中,有 26579(53.8%)名患者为男性。入院时接受脉搏血氧仪检测的新生儿和儿童比例从干预前组的 10001 名患者中的 2365 名(23.7%)增加到干预后组的 51328 名患者中的 45029 名(87.7%)。调整分析表明,与干预前相比,干预后患者接受脉搏血氧仪检测的可能性更大(调整后的优势比 40.10,95%CI 37.38-42.93;p<0.0001)。
大规模提高医院氧气服务是可行的,并且有可能改善临床结局。应鼓励政府制定国家氧气计划,并将投资重点放在已证明有效的干预措施上,包括将脉搏血氧仪引入常规医院护理以及临床和生物医学指导和支持。
