Rashid "Rash" Masum is a fictional character from the BBC medical drama Casualty, played by actor Neet Mohan. He first appeared in the eleventh episode of series thirty-two, which was broadcast on 4 November 2017. Rash is introduced into the series as a junior doctor undergoing his first year of the Foundation Programme. Rash is characterised as a shy and bashful doctor; he is an eternal optimist who tries to make others laugh. Casualty's series producer Lucy Raffety billed Rash as an "innocent, cautious and nice" character. Mohan took a temporary break from the show in 2019 and upon his return writers introduced a more assertive version of the character, with his "innocence jaded".
Writers created a relationship story for Rash and hospital porter Gemma Dean (Rebecca Ryan). Their romance is made difficult due to Rash's shy persona. Producers decided to focus an entire series of Casualty highlighting the pressure the NHS workforce endure. Rash's role in the saga explored hospital hierarchy and how junior doctors are burdened with pressure. The story incorpoarated a feud with his mentor and consultant Ethan Hardy (George Rainsford). Rash also spars with F1 Mason Reede (Victor Oshin), but his subsequent death at work has a negative effect on Rash. Other stories include Mohan participating in a car stunt and dealing with grief following the death of his mother, Madia Masum (Buckso Dhillon-Woolley). For his portrayal of Rash, Mohan was nominated for a "Best Newcomer" award at the 2019 National Television Awards.
