The overlapping COVID-19 crisis and the war starting in 2022 threaten front-line healthcare workers’ mental health, well-being and job retention in Ukraine. This paper provides a synopsis of a panel discussion held by the Global Mental Health Humanitarian Coalition in May 2022 and expert consultations with clinicians between December 2022 and February 2023 on these challenges. The crises created new problems and exacerbated many pre-existing difficulties. We found that healthcare workers had needed to mobilise previously untapped strengths, including portable emergency medical documents and bespoke local psychosocial support services, amid the costs and pressures of ongoing healthcare reforms.
