An improvement in accident-and-emergency waiting times at Scotland's newest hospital has been described as "promising" by Health Secretary Shona Robison.

Staff at the £842 million Queen Elizabeth University Hospital in Glasgow dealt with 93.8% of A&E patients within four hours, figures for the week ending November 15 showed.

The figure is a rise from 88.6% the previous week and compares to a record low of 77% in October.

The Scottish Government has set an interim target of having at least 95% of patients in A&E either admitted, transferred or discharged within four hours.

The latest weekly figures showed that performance remained stable at 94.4%.

Four health boards failed to meet the target - NHS Ayrshire and Arran (86.6%), NHS Highland (92.5%), NHS Greater Glasgow and Clyde (93.4%) and NHS Lanarkshire (94%).

Crosshouse Hospital in Kilmarnock was the worst-performing hospital that week, with 85.2% of patients seen within the four-hour target time.

Ms Robison said: "Performance for the week ending November 15 has remained stable with 94.4% of patients being seen within four hours at core A&E departments.

"While this is four percentage points higher than the same period last year, I have been clear that more needs to be done to improve and maintain A&E waiting times, in particular as we head into winter.

"However, progress has been made and monthly core site performance has exceeded 95% for three consecutive months, and is over two percentage points higher than September last year.

"The latest monthly performance figures also show that Scotland is the best-performing country in the UK."

Health boards were issued with advice in September on how to reduce A&E waiting times and Ms Robison added: "As we prepare to head into winter, we have been working closely with health boards and stakeholders to put further measures in place.

"This includes our winter guidance for boards, which was issued two months earlier this year than previous years, and additional investment of £10.7 million which will help ease pressure.

"Recently the Queen Elizabeth University Hospital in Glasgow announced a number of actions to increase assessment capacity and improve flow though the hospital, this includes the opening of the new ambulatory care unit and increased focus on discharge planning and multi-disciplinary working.

"It is promising to see that performance at the QEUH is at 93.8% this week, an improvement of over five percentage points compared to the previous week. This is an overall improvement of over 15 percentage points since week ending June 14.

"However, there is still more work to do and I am continuing to receive regular updates from sites experiencing challenges to ensure that progress is being made to drive down waiting times."
