Following the outbreak of hostilities in Ukraine and the resultant humanitarian crisis, the State of Israel deployed a field hospital inside Ukraine. Challenges included a large refugee population, disruption of routine medical services to the local population, first-time deployment of a civilian field hospital, and deployment to a country at war.

The activity of the field hospital during a deployment in Ukraine is described along with lessons learned for future deployments.

A Rapid Assessment Team (RAT) performed needs assessment and coordination with local authorities. The main necessity encountered was delivery of primary care to both the refugee and local population. During the 6 weeks of deployment, 6,161 patients were treated in the hospital. 65 patients were hospitalized and 59 underwent surgery. The hospital was completely digitalized. 103 remote consultations were performed using telemedicine techniques. Capacity building of local teams was given high priority and 796 Ukrainian health professionals underwent training.

Deployment of a national civilian field hospital in a country of war is possible through coordination with local authorities while undertaking the necessary security measures.

The change in caseload from expected war trauma to predominantly primary care necessitated agility in planning and operation with subsequent adaptation of hospital and staff structure.

The use of telemedicine enhanced capabilities, allowing access to consultation with the most experienced specialists in Israel.

Capacity building of local teams should be given a high priority. This was implemented by combining clinical training and the inclusion of a medical simulation unit in the hospital.

Dispatching a team delivering medical care and extending a helping hand in time of need, especially when done by a national entity, contributes greatly to building the people's faith, hope, and resilience during the crisis, and has a critical role in the recovery effort.
