Patient injuries in the treatment of superficial venous insufficiency registered in Finland between 2004 and 2017

Objectives This study aimed to identify the unintended incidents that led to patient injuries (PIs) in the treatment of superficial venous insufficiency (SVI). Methods PI claims filed with the Finnish Patient Insurance Centre between 2004 and 2017 involving SVI were reviewed. Factors contributing to PI were identified and classified. Results Eighteen (13.2%) of 136 compensated PIs in the specialty of vascular surgery were related to SVI. Only 4.7% of 383 SVI claims were compensated. The incidence of PIs was 9.9 per 100 000 patients. Fifteen patients had open surgery (83.3%) and three (16.7%) endovenous treatment. Two (11.1%) patients had necrotising fasciitis, four (22.1%) had deep vein injuries and two (11.1%) had a permanent nerve injury. Two (11.1%) patients had retained endovenous material that required surgical removal. Conclusions PIs were identifiable during all stages of care, perioperative injuries related to open surgery being the most common.
