Five health boards are failing to meet waiting-time targets for treating patients in accident and emergency (A&E), according to the latest weekly figures.

NHS Ayrshire and Arran, Forth Valley, Grampian, Greater Glasgow and Clyde and Lanarkshire fell short of the Scottish Government's interim goal to treat 95% of people in four hours.

NHS Greater Glasgow and Clyde was the worst-performing health board in the week ending June 21, with 91.8% of people seen within the target despite a significant improvement at South Glasgow University Hospital.

Last week, the health board revealed performance at Scotland's newest hospital improved by 11 percentage points to 89.6% after troubleshooters were sent in to help.

Aberdeen Royal Infirmary and Wishaw General Hospital were the worst-performing A&E sites, both with 87.8% patients seen within the target time.

Of the 25,338 people who attended Scotland's 30 emergency departments, 1,537 waited longer than four hours to be admitted, transferred or discharged.

The proportion of patients seen within that time was 93.9%, an improvement from 92.2% the previous week.

The figures show 80 people waited for more than eight hours and just one patient spent over 12 hours in A&E.

Health Secretary Shona Robison said: "Today's figures show an overall improvement of nearly eight percentage points since weekly reporting began in February.

"This demonstrates that, supported by the Scottish Government, our NHS staff are working extremely hard to cut waiting times and deliver a first-class service.

"I appreciate that there will be fluctuation in performance but I am confident that we are making progress.

"Long waits in particular have seen a further reduction since last week and, in fact, a substantial reduction since weekly reporting began in February.

"This week has seen the highest percentage of people seen and treated within four hours since weekly reporting began.

"The summer months do tend to show improvement, so what is important now is that we retain these levels of performance as we head towards next winter and make more, sustainable progress towards meeting our world-leading targets."
