Patrick has been described as "Casualty bad boy" by Marion McMullen of the Coventry Telegraph, who deemed him "arrogant, brusque and bad-tempered". Kelsey has disclosed that viewers of the show sometimes assume that he shares his character's temperament, but that he does not receive any hostility for it, surmising: "It must mean I'm somehow putting across the fact that there really is a nice bloke behind the brick wall that Patrick puts up." Kelsey feels that the only trait of Patrick's which he shares is his "dry sense of humour". He has assessed that Patrick is "very good" at his job, but that his bedside manner becomes worse as the series develops. He has stated, however, that: "Away from the eyes of his colleagues he is perfectly capable of showing real humanity and care." Kelsey believes that Patrick softened in the show's fifteenth series, but that he reverted to form "with a vengeance" in series sixteen. He believes that Patrick would be spoiled for the show's viewers if it was ever explained why he behaves the way he does, and prefers playing Patrick as the "bad guy". Discussing Patrick's relationship with PC Rachel James, Kelsey assessed: "Spiller and Rachel just fancy each other - it's all about sex." SHO Lara Stone was introduced as a love-interest for Patrick, with producer Mervyn Watson explaining: "I felt it would be good to bring Patrick Spiller into contact with a very worthy adversary, a woman who was his equivalent." Christine Stephen-Daly, who plays Lara, has commented that Patrick is Lara's type, but that they clash often as they are so similar, asserting that they are both: "arrogant, like getting their own way and enjoy being in control." Stephen-Daly feels that Lara is more "caring" than Patrick, whose bedside manner "leaves a lot to be desired." In an interview with Inside Soap, Kelsey revealed he took Patrick's coffin plaque, which is hung in his bathroom underneath the coffin plaque of his Emmerdale character, Dave Glover. He added he had "got a nice set now!"

Reception
Charlie Catchpole of the Daily Mirror was keen to see a television doctor who did not like people and cited Patrick as an example. Catchpole wrote, "he's selfish, cruel, bad-tempered, thick-skinned, homophobic and misogynistic. Just wait till we discover what his bad points are." A reporter for Daily Record noted that Patrick had a "lack of charm", which got him in trouble.
