Abstract
BACKGROUND: During the Coronavirus Disease 2019 (COVID-19) outbreak in the Netherlands, the demand for intensive care beds exceeded availability within days. Initially, patients were redistributed regionally by ground transport. When transport over longer distances became necessary, we initiated a new Helicopter Emergency Medical Service (HEMS) operation. We hypothesize that the transport of contagious COVID-19 patients is feasible and safe for patients and HEMS personnel. METHODS: In this retrospective, single-centre observational study, flight and monitor data were used to calculate the exposure time of the retrieval team to COVID-19 patients. All the crew members (n = 18) were instructed on the proper use of personal protective equipment (PPE), dressing and undressing routine using buddy check supervision and cleaning procedures. All the team members were monitored for possible COVID-19 symptoms, as advised by our National Institute for Health and Environment. One month after completing the aeromedical transport all crew members were asked to donate a blood sample which was examined for the presence of IgG antibodies to SARS-CoV-2. RESULTS: From March 24 to May 25, 2020 the HEMS team transported 67 ventilated critical care COVID-19 patients. The exposure time was 7451 min (124 h and 11 min). One HEMS member reported pneumonia 6 weeks before the start of the patient transport. He tested positive for IgG SARS-CoV-2 by serology testing. We speculate that he was infected before the start of the operation; irrefutable evidence is lacking to support this claim because we did not perform serology testing before this operation started. CONCLUSION: Occupational COVID-19 exposure during helicopter transport of ventilated critical care COVID-19 patients can be performed safely when proper PPE is applied.
