David Hide is a staff nurse who currently works in the emergency department of Holby City Hospital. He started working in the department at the end of April 2016 as a replacement for Ben "Lofty" Chiltern who left the previous month. Prior to joining the ED, David had taken a two-year break from his career following a split from his wife, Rosa. Suffering from bipolar, David found it hard to control his emotions during this time and was deemed unfit to work by the Department of Work and Pensions. However, after getting his life back on track, he joined Holby in need of a fresh start.
