The Royal Alexandra Hospital is the main hospital in Paisley serving a large catchment area as much as 200 000 from Renfrewshire, stretching all the way to Oban and Argyll The hospital is owned and run by NHS Greater Glasgow and Clyde, previously NHS Argyll & Clyde.
Royal Alexandra provides the local catchment area with many services. These include: an A&E department; Psychiatric; general medical and surgical services; trauma and emergency surgery centre and a children's ward.
The hospital contains the only maternity unit for the whole South Clyde area, after this was done away with at Inverclyde Royal Hospital. The hospital also received some re-located services from Vale of Leven Hospital in Alexandria as part of a shuffle. Nonetheless, other services from this hospital will re-locate to Southern General in Glasgow to help balance this out fairly.
The hospital received patients from the 2007 Glasgow International Airport attack, including one of the suspects who was taken to the hospital under arrest with severe burns. Parts of the hospital were later evacuated when a suspect device, originally believed to be a suicide belt, was discovered on the suspect. On the afternoon of July 1 a controlled explosion of a car was carried out in the car park of the hospital.
