A major innovation which will save the lives of patients has been invented by doctors in King’s Lynn.

Consultant Dr Peter Young and Dr Maryanne Mariyaselvam, who are based at the Queen Elizabeth Hospital, have devised WireSafe.

It’s designed to prevent a guide wire being left in a patient after a central line, or central venous catheter, has been inserted.

In August 2017, the Royal College of Emergency Medicine issued a safety alert identifying guide wire retention as the top ranking ‘never event’ in emergency medicine.

The device, which is a box containing all of the equipment needed to complete the insertion procedure, can only be opened using the guide wire as a key and ensures it is safely removed.

Under simulated tests, WireSafe has been proven to be 100pc effective in ensuring that the guide wire is removed at the critical time.

Dr Young said: “Central lines are often inserted during incredibly stressful situations and the current procedure relies on the clinicians remembering to remove the guide wire by following a check list, which is not always possible if a doctor is distracted, tired or inexperienced.

“We have created a human engineered solution to eliminate that issue and ensure positive results for both the patients and the doctors. We have found that doctors are psychologically harmed as a result of incidents like this.

“As doctors we have the privilege of making an impact on individual people’s lives but we also have the ability here to support doctors to do their job safely.”

Dr Young and Dr Mariyaselvam came up with the idea after spotting the potential to improve the current operating procedure which relies on doctors following a check list while inserting the central line in emergency situations.

Dr Mariyaselvam, who is based at the hospital but is completing a Doctorate with Cambridge University, said “We came up with an out of a box solution to help make life easier for the doctor to complete the medical procedure and to make the incident impossible.

“We looked at the whole process of the procedure and were able to define when the issue was most likely to happen. We want to prevent any harm coming to patients and to support clinicians to do their job safely.

“By using the equipment you are supposed to be removing, it’s an ideal safety solution.”

WireSafe, which contains a suture, suture holder and antimicrobial dressing, can only be opened by passing the wire through the lightbulb shape key on the front.

The box, which is made from environmentally friendly material, also provides a convenient and safe disposal of the guide wire and sharps.

Dr Young added: “The average NHS innovation takes 17 years to go through the relevant processes but WireSafe has taken two years and it is now being used by several hospitals across the country.

“This is the perfect device as it not only protects the patient but also the doctor and the institution.”
