This study was performed to measure if the introduced interventions in leg ulcer care in a selected Swedish county yield a detectable reduction in leg ulcer prevalence in the population. A validated postal questionnaire sent to 10,000 (9,868) randomly selected 30–89 year olds in the Skaraborg county (255,042 inhabitants). All positive responders were telephone interviewed and verified ulcer patients were clinically examined including assessment of arterial/venous circulation with hand-held Doppler and, where indicated, duplex ultrasound scanning. All results were compared with numbers from 1990 (initial study). The response rate was 82% (8,070/9,868), 200 active ulcers and 290 previous ulcers. The calculated prevalence was 0.75% for 30–89 years and 1.05% for 50–89 years (2.1% in 1990). The leg ulcer prevalence was reduced by 32% (0.52% compared to 0.77% in 1990), and the relative risk was reduced by 50% (95%, CI 0.36–0.69). The study shows a true reduction in leg ulcer prevalence detectable in the population supporting a successful care of leg ulcer patients.
