There are worries that Channel 4's long-running show, 24 Hours in A&E, might be cancelled after 13 years on screens.
The network stated that no new episodes would be filmed this year and that a decision regarding its future would be made later.
Since its debut in 2011, the series, which documents life in Britain's busiest hospital departments, has been a consistent presence on Channel 4, spanning 32 series and more than 300 episodes.
The show initially filmed at King’s College Hospital in London before relocating to St George’s Hospital in South London in 2014.
Over the past two years, it has increasingly featured episodes filmed in the North of England as part of Channel 4's effort to decentralise production from London.
Reports first emerged via Broadcast about Channel 4's decision to suspend filming, impacting more than 100 crew members employed by production company The Garden.
But the broadcaster has assured viewers there are some completed episodes ready for broadcast.
In a statement, a spokesperson for Channel 4 said: “24 Hours in A&E is a much loved Channel 4 show and audiences will still be able to watch new episodes in 2024 and 2025 across our streaming and linear channels
“Whilst we’re not filming more new episodes this autumn, we have a high number of recently filmed but not yet aired episodes, which means we’ll continue to bring all the behind-the-scenes access from Queen’s Medical Centre Nottingham’s A&E department.
“Channel 4 always looks to provide a mix of new shows and familiar returners and 24 Hours in A&E remains an important part of that distinctive blend.
“We’ll make a recommission decision at an appropriate time, once we’ve aired more of the episodes we have already filmed.”
The Standard has contacted Channel 4 for comment.
The update comes after Channel 4 bosses unveiled a new five-year plan in January, in which they announced the broadcaster will be focusing on streaming services rather than traditional television formats.
