Little is known on the trends of aeromedical retrieval (AR) during social isolation.
To compare the pre, lockdown, and post-lockdown AR patient characteristics during a period of Coronavirus 2019 (COVID-19) social isolation.
An observational study with retrospective data collection, consisting of AR between 26 January and 23 June 2020.
There were 16 981 AR consisting of 1983 (11.7%) primary evacuations and 14 998 (88.3%) inter-hospital transfers, with a population median age of 52 years (interquartile range 29.0-69.0), with 49.0% (n = 8283) of the cohort being male and 38.0% (n = 6399) being female. There were six confirmed and 230 suspected cases of COVID-19, with the majority of cases (n = 134; 58.3%) in the social isolation period. As compared to pre-restriction, the odds of retrieval for the restriction and post-restriction period differed across time between the major diagnostic groups. This included, an increase in cardiovascular retrieval for both restriction and post-restriction periods (odds ratio (OR) 1.12, 95% confidence interval (CI) 1.02-1.24 and OR 1.18 95%, CI 1.08-1.30 respectively), increases in neoplasm in the post restriction period (OR 1.31, 95% CI 1.04-1.64) and increases for congenital conditions in the restriction period (OR 2.56, 95% CI 1.39-4.71). Cardiovascular and congenital conditions had increased rates of priority 1 patients in the restriction and post restriction periods. There was a decrease in endocrine and metabolic disease retrievals in the restriction period (OR 0.72, 95% CI 0.53-0.98). There were lower odds during the post-restriction period for retrievals of the respiratory system (OR 0.78, 95% CI 0.67-0.93), and disease of the skin (OR 0.78, 95% CI 0.6-1.0). Distribution between the 2019 and 2020 time periods differed (P < 0.05), with the lockdown period resulting in a significant reduction in activity.
The lockdown period resulted in increased AR rates of circulatory and congenital conditions.
在社交隔离期间，航空医疗后送（AR）的趋势鲜为人知。
比较 2019 年冠状病毒病（COVID-19）社交隔离期间，封锁前、封锁中和封锁后的 AR 患者特征。
这是一项回顾性数据收集的观察性研究，包括 2020 年 1 月 26 日至 6 月 23 日的 AR。
共有 16981 次 AR，包括 1983 次（11.7%）初次疏散和 14998 次（88.3%）院内转院，人群中位数年龄为 52 岁（四分位距 29.0-69.0），其中 49.0%（n=8283）为男性，38.0%（n=6399）为女性。有 6 例确诊病例和 230 例疑似病例，COVID-19 病例大部分（n=134；58.3%）发生在社会隔离期间。与限制前相比，限制期和限制后期间，主要诊断组之间的检索几率在不同时间存在差异。这包括心血管检索的增加，限制期和限制后期间的（比值比（OR）1.12，95%置信区间（CI）1.02-1.24和 OR 1.18，95%CI 1.08-1.30），肿瘤的增加在限制后期间（OR 1.31，95%CI 1.04-1.64）和先天性疾病的增加在限制期间（OR 2.56，95%CI 1.39-4.71）。心血管疾病和先天性疾病在限制期和限制后期间有更高的 1 级优先患者比例。限制期内分泌和代谢性疾病检索的几率降低（OR 0.72，95%CI 0.53-0.98）。在限制后期间，呼吸系统（OR 0.78，95%CI 0.67-0.93）和皮肤疾病（OR 0.78，95%CI 0.6-1.0）的检索几率较低。2019 年和 2020 年期间的分布不同（P<0.05），封锁期导致活动量显著减少。
封锁期导致循环系统和先天性疾病的 AR 率增加。
