“Our hardworking NHS staff have done an incredible job despite a very challenging winter.
“It is thanks to their efforts almost nine in 10 people were admitted, discharged or transferred within four hours despite our A&Es being the busiest they have been in a decade.
“In the last week alone, severe weather has caused significant disruption to our road and rail networks, and staff across our health service have once again gone that extra mile to ensure that the people of Scotland remain safe.”
