We are extremely grateful to all NHS and care staff for their hard work and dedication in trying to meet patient needs in such exceptional circumstances. This includes those who have returned to the NHS (such as clinicians returning from academia, retirement and other industries); students who have left their training early to do so, and staff that have been redeployed to manage capacity constraints in other areas of the NHS. We share concerns that some NHS and care staff are suffering from fatigue, exhaustion and a general feeling of being “burnt out” and that the wellbeing of staff (particularly their mental health) is at significant risk.
