In the week ending January 24, Wishaw A&E recorded 1180 attendancies.
Of these, only 86.8 per cent were seen within the Scottish Government’s target of four hours - for Lanarkshire as a whole that was 91.7 per cent, and nationally in Scotland 93.8 per cent.
In Wishaw 186 people waited over four hours, 21 people waited over eight hours, and two had to wait over 12 hours.
The figures are released just as better news on waiting times nationally was being welcomed.
During the month of December 94.9 per cent of patients were seen and subsequently admitted, transferred or discharged within four hours from Scotland’s A&E departments.
This is five percentage points higher than December 2014 and the best performance during the month of December since 2009, although Scottish Ministers expect 95 per cent of patients to be dealt with in the four-hour period.
Health Secretary Shona Robison welcomed the national figures.
“We know that the winter months bring additional demands across the whole health and social care services,” she said.
“We have seen that demonstrated over recent weeks, but, thanks to the dedication of NHS and social care staff, we have also seen a consistent improvement on last year.
“However, there is no doubt that A&E performance will continue to fluctuate, not only from week to week, but also from hospital to hospital, particularly at this time of year. There is still clearly more work to be done to build on and retain performance across the whole country.”
