The COVID-19 pandemic led authorities to evacuate via various travel modalities critically ill ventilated patients into less crowded units. However, it is not known if interhospital transport impacts COVID-19 patient's mortality in intensive care units (ICUs). A cohort from three French University Hospitals was analysed in ICUs between 15th of March and the 15th of April 2020. Patients admitted to ICU with positive COVID-19 test and mechanically ventilated were recruited.
Among the 133 patients included in the study, 95 (71%) were male patients and median age was 63 years old (interquartile range: 54-71). Overall ICU mortality was 11%. Mode of transport included train (48 patients), ambulance (6 patients), and plane plus helicopter (14 patients). During their ICU stay, 7 (10%) transferred patients and 8 (12%) non-transferred patients died (p = 0.71). Median SAPS II score at admission was 33 (interquartile range: 25-46) for the transferred group and 35 (27-42) for non-transferred patients (p = 0.53). SOFA score at admission was 4 (3-6) for the transferred group versus 3 (2-5) for the non-transferred group (p = 0.25). In the transferred group, median PaO/FiO ratio (P/F) value in the 24 h before departure was 197 mmHg (160-250) and remained 166 mmHg (125-222) in the first 24 h post arrival (p = 0.13). During the evacuation 46 (68%) and 21 (31%) of the patients, respectively, benefited from neuromuscular blocking agents and from vasopressors. Transferred and non-transferred patients had similar rate of nosocomial infections, 37/68 (54%) versus 34/65 (52%), respectively (p = 0.80). Median length of mechanical ventilation was significantly increased in the transferred group compared to the non-transferred group, 18 days (11-24) and 14 days (8-20), respectively (p = 0.007). Finally, ICU and hospital length of stay did not differ between groups.
In France, inter-hospital evacuation of COVID-19 ventilated ICU patients did not appear to increase mortality and therefore could be proposed to manage ICU surges in the future.
新冠疫情致使当局通过多种交通方式，将重症机械通气患者转移至人员密度较低的病房。然而，院际转运对重症监护病房（ICU）中新冠患者死亡率的影响尚不清楚。对法国三家大学医院的一个队列进行了分析，研究对象为2020年3月15日至4月15日期间入住ICU的患者。纳入的患者为新冠病毒检测呈阳性且接受机械通气的ICU患者。
在纳入研究的133例患者中，95例（71%）为男性，中位年龄为63岁（四分位间距：54 - 71岁）。ICU总体死亡率为11%。转运方式包括火车（48例患者）、救护车（6例患者）以及飞机加直升机（14例患者）。在ICU住院期间，7例（10%）转运患者和8例（12%）未转运患者死亡（p = 0.71）。转运组入院时的中位简化急性生理学评分（SAPS II）为33（四分位间距：25 - 46），未转运患者为35（27 - 42）（p = 0.53）。转运组入院时的序贯器官衰竭评估（SOFA）评分为4（3 - 6），未转运组为3（2 - 5）（p = 0.25）。在转运组中，出发前24小时的中位动脉血氧分压/吸入氧浓度比值（P/F）为197 mmHg（160 - 250），到达后的最初24小时仍为166 mmHg（125 - 222）（p = 0.13）。在转运过程中，分别有46例（68%）和21例（3l%）患者使用了神经肌肉阻滞剂和血管活性药物。转运患者和未转运患者的医院感染率相似，分别为37/68（54%）和34/65（52%）（p = 0.80）。与未转运组相比，转运组的机械通气中位时长显著延长，分别为18天（11 - 24天）和14天（8 - 20天）（p = 0.007）。最后，两组间的ICU住院时长和住院总时长无差异。
在法国，对新冠机械通气ICU患者进行院际转运似乎并未增加死亡率，因此未来可考虑用于应对ICU床位紧张的情况。
