Sack the sock! RUH takes major step to reduce unnecessary use of compression socks
The Royal United Hospitals (RUH) Bath NHS Foundation Trust is improving patient comfort, reducing waste and saving millions of single-use compression socks from landfill after updating guidance on the use of anti-embolic, or compression, stockings.
Compression socks, have long been used in healthcare settings to help prevent blood clots (venous thromboembolism) in patients following surgery or during periods of reduced mobility. However, the latest evidence shows that for many patients who are already receiving bloodthinning medication, compression stockings do not provide any additional benefit. Research has also found no benefit from their routine use for patients undergoing day-case procedures.
In response, the RUH's Haematology team has swiftly updated guidance to ensure compression stockings are only used where they are clinically needed.
This has improved the comfort of patients, reduced risks associated with sock use, such as skin irritation, and is expected to save around 270 metrics tons of CO2 a year. The change in guidance is also expected to save the RUH a total of £2.5millon over the next five years.
Sophie Millington, Lead Nurse for Thrombosis and Anticoagulation at the RUH said:
"Our priority is always to provide safe, evidence-based care for our patients. The latest research shows that these socks do not provide additional benefits for many patients when appropriate medication is already being used to prevent blood clots.
"By updating our guidance, we can continue to protect patients from blood clots while reducing unnecessary treatment, improving comfort and supporting our sustainability goals. It's a great example of how small changes can make a big difference for our patients, for the wider NHS and for the planet."
The initiative supports the RUH's wider ambition to reduce waste, improve value and contribute to the NHS net zero agenda.
