Clinical Negligence Claims Against Vascular Surgery in the United Kingdom: An Observational Study.

Background: Claims for clinical negligence awarded to patients and their families are on the increase. The annual "cost of harm" is approximately £7-9 billion in the United Kingdom. In 2017, the National Health Service (NHS) resolution service reported that they mediated more claims than in their entire history. Vascular surgery is a specialty with a disproportionately higher number of claims for clinical negligence. The aim of this observational study was to review the trends of clinical negligence claims in vascular surgery within the United Kingdom. The costs and the primary cause for the complaint were evaluated.

Methods: A retrospective observational study was performed. Clinical negligence claims in vascular surgery between the financial years of April 2005/2006 to April 2018/2019 were requested from NHS resolution under the Freedom of Information Act. Data were provided on November 8, 2019. All data were anonymized, and any categories containing fewer than five claims were removed to protect the identity of claimants.

Results: Over the 13-year period, 1,189 claims in vascular surgery were identified, with the annual mean (range) being 91 (20-134) claims per year. Of 1,189 claims, 875 (74%) are closed with payments made to the claimants. The mean annual total payment was £10,015,373. Delay in treatment was the most common cause for litigation claims in vascular surgery with 157 closed claims costing £33,255,248 over the 13-year period. Lower limb amputation was the most common primary injury claim with 140 closed cases but had a larger financial cost at £64,155,969.

Conclusions: Clinical negligence claims in vascular surgery within the United Kingdom have been increasing steadily over the last 13 years and with a changing claims culture is expected to continue. The most common cause for claims with damages paid was delay in treatment, and lower limb amputation was the most common injury suffered. Improved consent, better communication with patients, and a higher surgical skill level could significantly reduce the number of future claims.
