NHS Scotland has recorded its worst weekly performance for accident and emergency waiting times in almost two years, new figures reveal.

During the week ending January 8, more than one in ten patients (12.1%) waited more than four hours to be admitted, transferred or discharged from the country's A&E departments.

The Queen Elizabeth University Hospital in Glasgow recorded its worst weekly A&E performance since opening in April 2015.

A quarter of patients (25.2%) at the new hospital had to wait beyond the waiting time target of four hours.

Two other hospitals, Hairmyres in East Kilbride, South Lanarkshire, and Glasgow Royal Infirmary, also recorded a quarter of their A&E patients missing the target.

The Scottish Government has set health boards a target of ensuring no more than 5% of patients wait more than four hours.

The latest figures show it is the worst performance in A&E departments for 22 months, since the week ending March 1, 2015.

The week was also the worst for patients having to wait more than 8 and 12 hours in the last 22 months.

A total of 454 patients had to wait more 8 hours while 101 had to wait 12 hours, more than double the waiting time target.
