The number of patients dying in emergency departments increased by a third last year compared with before the pandemic, an analysis suggests.

More than 23,000 patients died in accident and emergency in 2022, compared with 17,502 in 2019.

The new figures, released under freedom of information laws, come after patients experienced record waits in A&E last year.

Last year almost 350,000 patients waited 12 hours in A&E after a decision was made to admit them. That means an average of 1,000 patients a day were waiting that long, which is almost the entire figure for all of 2015.
