背景：下肢静脉性溃疡是一种常见于65岁及以上老年人的疾病。然而，发病率和流行率尚未得到很好的确定。目的：我们的目的是估计老年人下肢静脉性溃疡的患病率和发病率。方法：我们研究了全科医学研究数据库，验证了我们的病例确定策略，并估计了静脉性腿部溃疡的年患病率和发病率。结果：我们的确定策略的阳性预测值为98.3%（95%可信区间[CI]， 90.0, 100.0）。老年人下肢静脉溃疡的年患病率为1.69 （95% CI, 1.65, 1.74）。男性的总发病率为0.76 (95% CI, 0.71, 0.83)，女性为1.42(1.35,1.48)/ 100人年。结论：下肢静脉性溃疡是65岁及以上老年人的重要疾病。与以前的研究相比，由于我们使用的是已知规模人群的医疗记录，因此我们的结果是精确的，而且偏差较小。
Background: Venous leg ulcer is a disease most common in those aged 65 years and older. However, the incidence and prevalence have not been well established.Objective: Our purpose was to estimate the prevalence and incidence of venous leg ulcers in the elderly.Methods: We studied the General Practice Research Database, validated our case ascertainment strategy, and estimated the annual prevalence and incidence of venous leg ulcer.Results: The positive predictive value of our ascertainment strategy was 98.3% (95% confidence interval [CI], 90.0, 100.0). The annual prevalence of venous leg ulcer among the elderly was 1.69 (95% CI, 1.65, 1.74). The overall incidence rate was 0.76 (95% CI, 0.71, 0.83) for men and 1.42 (1.35, 1.48) per 100 person-years for women.Conclusion: Venous leg ulcer is a significant problem in those aged 65 years and older. As compared with previous studies, because we used medical records from a population of known size, our results are precise and less biased.
