The 100th episode of the hit TV show 24 Hours in A&E filmed at St George’s Hospital is set to air tonight.

The Channel 4 docuseries, which is now into its 14th series, reaches the centenary landmark this evening (January 16).

The 100th episode – ‘Wrong Place, Wrong Time’ – will feature three middle-aged women who were stabbed in broad daylight in a supermarket car park in Surrey.

Although they were previously unknown to each other, they were rushed to St George’s for specialist trauma care following the horrific attack.

St George’s Dr Will Glazebrook, consultant in emergency medicine, said: “We are indebted to every non-clinical team and support team, who help make this series possible.

“They often work out of hours and beyond their job descriptions, but not in a way they begrudge, because it remains, after all these years, a fantastic and exciting project to be part of.

“So why do we continue to do it? There are many reasons, although first and foremost is the fantastic opportunity we get to celebrate and promote what we do, and put our best foot forward.

“At a time when the NHS is under more pressure than ever, 24 Hours in A&E is a weekly reminder, were it needed, of the amazing work the NHS does all day every day – and night – not only at St George’s, but across the whole country.

“The 110 fixed cameras used to film the programme could be put up in any emergency department in the country and the same level of care and passion would be recorded.”

The docuseries comes after 56 days of filming in April and May last year, with 100 fixed rig cameras and 76 microphones capturing the goings on within the hospital’s emergency department.

It is now the longest-running programme of its category on television in the United Kingdom and is said to average between 2 million and 2.5 million viewers per episode.

Dr Glazebrook added: “Another of the great things about the programme is that, working in an emergency department, we rarely get to see what happens when patients leave either to go home or are admitted.

“At St George’s, we can see 500 patients per day and getting meaningful follow up information on this number is impractical and impossible. 24 Hours in A&E affords a peek into the work of the rest of the hospital, but more interestingly, the follow up of home and family is more rewarding to me.”

The 24 Hours in A&E programme was relocated to St George’s after six seasons and 70 episodes in King’s College Hospital in 2014.

Spencer Kelly, 24 Hours in A&E’s executive producer also said: “24 Hours in A&E is a series where you often see the best of humanity.

“Staff caring for patients, families supporting loved ones and patient stories about overcoming life’s challenges are genuinely life affirming and positive – and maybe more poignant in this day and age.”

The 100th episode will air at 9pm on Channel 4 tonight (January 16).
