Scotland's A&E departments have missed a key waiting time target, according to the latest weekly figures.

In the week ending September 20, 94.4% of patients were seen and either admitted, transferred or discharged within four hours, down from 95.6% the week before.

Six health boards failed to meet the Scottish Government's interim target of 95% of people being dealt with in four hours.

These were NHS Ayrshire and Arran (89.9%), NHS Fife (92.9%), NHS Forth Valley (90.6%), NHS Greater Glasgow and Clyde (93.6%), NHS Lanarkshire and NHS Lothian (both 94.9%).

The poorest performing site was Ayr's University Hospital, which saw 83.9% of patients within the four-hour target.

Across Scotland, 88 people had to wait eight hours or more to be treated while two patients waited 12 hours or more.

Health Secretary Shona Robison said: "A&E performance is always likely to fluctuate from week to week. However it is encouraging to note that performance is over one percentage point better than the equivalent week last year - and there has been an overall improvement of over eight percentage points since weekly reporting began in February.

"However it is crucial, especially as we head into winter, that NHS boards across Scotland continue to work hard to ensure that A&E performance is maintained and improved upon. The Scottish Government will go on providing full support in terms of planning and investment to support these efforts.

"The level of improvement we have seen in Scotland this summer shows that while winter will continue to bring extra pressures that affect performance, the NHS has appropriate plans and processes in place to allow a prompt recovery."
