About A&E types
Type 1 departments are major, consultant-led A&Es open 24 hours with full resuscitation facilities. Types 2 and 3 are single-specialty units (such as eye casualty), urgent treatment centres and minor injury units. The “all types” figure includes all of these, which is why it is usually higher than the type 1 figure.
