Casualty series 1

The first series of the British medical drama television series Casualty began airing on 6 September 1986, and concluded on 27 December 1986. The show was created by Jeremy Brock and Paul Unwin after the pair were both hospitalised for different reasons. Brock and Unwin were deeply concerned with what they saw within hospitals and decided to pitch a document in 1985 for the BBC. It was reported the pitch document 'read like a manifesto', and the show was then commissioned. Geraint Morris was appointed as the show's producer. Casualty was commissioned to boost ratings on BBC One at peak times after ratings began to decline between 1984 and 1985. Prior to first series airing, Brock and Unwin visited a hospital in Bristol where they met a charge nurse called Pete Salt. Salt was appointed the series medical advisor.

The first series of Casualty consisted of fifteen episodes, which aired weekly on a Saturday night. Each episode was individually titled. The first series featured ten main characters, who were all appointed different roles within the A&E department. By the end of the first series, two actors would not be returning for the second series: Julia Watson (Baz Samuels) and George Harris (Clive King). Watson eventually returned to the programme in 1995.

Development
The idea of Casualty came together when co-creators Jeremy Brock and Paul Unwin were both hospitalised for different reasons. During their time at the hospital, the pair were 'deeply concerned by what they saw'. Brock and Unwin pitched a document and sent it to the BBC in 1985. Unwin said in an interview with Radio Times that their pitch 'read like a manifesto', with the first sentence being: "In 1948, a dream was born - a National Health Service. In 1985, the dream is in tatters." Unwin said that he and Brock were both 'left–wing and passionate', and that they 'knew what stories there were to tell'. After the commissioning of Casualty, the BBC decided to team Unwin and Brock up with television producer Geraint Morris.

One of the reasons Casualty was produced was to help boost decreasing ratings for the BBC between 1984 and 1985 during peak viewing times on Friday and Saturday evenings. Before Brock and Unwin scripted the first series, they took a visit to a hospital based in Bristol. There, they met Pete Salt, a charge nurse. Salt was appointed the series medical advisor, advising the team of Casualty on what was and wasn't medically possible or accurate.
