On August 4, 2020 a massive explosion struck the Beirut Harbor in Lebanon. Approximately 220 people were killed and over 7000 were injured, of which 12% were hospitalized. Despite being weakened by an economic crisis and increasing numbers of COVID-19 cases, the national healthcare system responded promptly. Within a day, International Emergency Medical Teams (I-EMTs) started arriving. Previous studies have found that I-EMTs have arrived late and have not been adapted to the context and dominating healthcare needs. The aim of this study was to document the organization, type, activity, and timing of I-EMTs deployed to Beirut and to discuss their relevance in relation to medical needs.

Data on all deployed I-EMTs were retrieved from all available sources, including internet searches, I-EMT contacts, and from the World Health Organization (WHO) EMT coordination cell (EMT CC) in Lebanon. The WHO EMT classification was used to categorize deployed teams. Information on characteristics, timing, and activities was retrieved and systematically assessed.

Nine I-EMTs were deployed to Beirut following the explosion. Five were equivalent to EMT Type 2 (field hospitals), of which three were military. The first I-EMT arrived within 24 hours, while the last I-EMT was set up one month after the explosion. Four civilian I-EMTs provided non-clinical support as EMT Specialized Care Teams. A majority of the I-EMTs were focused on trauma care. Three I-EMT Specialized Care Teams were rapidly re-tasked to support COVID-19 care in public hospitals.

A majority of the deployed I-EMT Type 2 were military and focused on trauma care rather than the normal burden of disease, including COVID-19. Re-tasking of EMTs requires flexible EMTs. To be better adapted, the I-EMT response should be guided by a systematic assessment of both healthcare capacities in the affected country as well as the varying health effects of hazards before deployment.
