Arthur Digby is a fictional character from the BBC medical drama Holby City, played by actor Rob Ostlere.

Ostlere's first days on-set influenced various aspects of Arthur's characterisation such as his "preppy attire", fidgeting with his glasses and his clumsy nature.

In his first year on-screen he works closely with mentor Antoine Malick (Jimmy Akingbola) and staff nurse Chantelle Lane (Lauren Drummond).

His second year saw him working alongside F1 doctors Dominic Copeland (David Ames) and Zosia March (Camilla Arfwedson) while remaining on Keller.

Writers then introduced an issue lead storyline for the character as Arthur begins to behave anxiously, self medicating and finally being diagnosed with General Anxiety Disorder (GAD).

Arthur approaches patient cases with over-analytical enthusiasm, forgoing the bedside manner for piles of medical journals and unusual diagnoses.Arthur is characterised as having his own sense of logic that differs to the rest of the hospital staff.

This was made worse following his first day on-set when Producers mistook Ostlere's bag for an acting prop belonging to Arthur because it fitted their vision of the character.

[2] Glaser told Melanie Hancill of The People her character Gemma and Arthur share a competitive relationship because they are trying to earn the same role and the F1 prize in the hospital.

Arthur struggles to live up to his new-found reputation, especially when he fails to reach a diagnosis for a patient and hastily dismisses a staff nurse's accurate findings.

Consultant general surgeon Michael Spence (Hari Dhillon) decides to reward Arthur by placing him in charge of the ward.

[14] Chantelle is critically injured in the accident and he rescues her from the wreckage, the actor added that "it's emotional for him seeing the girl he loves in danger."

[15] Chantelle offers her support to Arthur, Drummond explained that her and Ostlere's characters are brought to the realisation that their close bond is not helping them overcome their ordeals.

[16] Following the departures of Drummond and Akingbola, Ostlere began working closely with David Ames and Camilla Arfwedson who play F1 doctors Dominic Copeland and Zosia March respectively.

Working together on Keller Ward proves problematic because Arthur and Malick were close colleagues so his return inevitably causes friction.

In an interview published by What's on TV, Ames stated "there's clearly a lot of friction between them and Dom likes to push Arthur's buttons, not least just to entertain himself.

Arthur takes control of Keller on Sacha's orders, but an opportunistic Dom makes him appear unable to manage the situation.

The set is named "Arthur's flat" and often film in dressing gowns and Ostlere uses the on-set bed to rest, learn his lines and tried to spend more time there.

[22] In 2015, Producer Simon Harper decided to split up the trio having Dom staying on Keller, Zosia moving to Darwin and Arthur working on AAU.

Ostlere told Bill Gibb from The Sunday Post that Arthur's storyline was realistic because of the demands junior doctors face in the NHS.

[26] Ostlere learned that many people in society experience anxiety and believed that it was an important subject matter for Holby City to portray.

It was also important for the show to make the storyline accurate for instance having "full-blown panic attacks" and more subtle moments with Arthur struggling to control it inside.

[26] Dom decides to take Arthur to a seaside resort to give him a break and help him recover following the orders of concerned CEO Henrik Hanssen (Guy Henry).

[28] After his professional hero Professor Walter Dunn (Philip Fox) was admitted to AAU with issues related to alcoholism, Arthur received "a massive wake-up call" during a conversation with Guy Self (John Michie).

[32] The examination is a result of Arthur being tested for compatibility to become a live liver donor for Morven's ill father Austin Shreve (Clinton Blake).

[34] Gillian Nuttall, founder of Melanoma UK praised Holby City for raising awareness of the condition and credited them with an increase in callers to their helpline.

Arthur returns alongside Essie and Jasmine Burrows (Lucinda Dryzek); they all appear as a vision to Jac Naylor (Rosie Marcel), who is terminally ill and fears dying.

"[22] The Holby City audience viewed Arthur, Dom and Zosia as the show's "dream team" and were sad when they furthered their careers separately.

He targeted Arthur as being one of the causes, adding "oh yes, and if this weren't bad enough, our beloved Dr Digby starts down a very dodgy road.

[43] A reporter of the South Wales Echo found it odd that the "scarily confident" Zosia and "dear little Digby" had so much in common as friends despite being "complete opposites".

[45] Another opined that Arthur and Dom's feud is the type of behaviour likely to make viewers research private health care rather than use the NHS.
