Several recent advances in wound care may offer promise for the treatment of hard-to-heal venous leg ulcers. One such treatment is Apligraf (Graftskin), a bilayered, living human skin construct. To assess the economic impact of Graftskin, a model was constructed to compare the annual medical costs and cost-effectiveness of treating hard-to-heal venous leg ulcers with Graftskin vs. compression therapy using Unna's boot. A semi-Markov model was used to describe the pattern of ulcer treatment, healing, and recurrence among patients with venous leg ulcers. Patients received 1 of 2 treatment regimens, Graftskin or Unna's boot, and were followed in the model for a 12-month period. The analysis was done from the perspective of a commercial health plan; therefore, only direct medical costs were included. Health care resource use included the primary therapeutic intervention, additional compression dressings, physician office visits, home health visits, laboratory tests and procedures, management of adverse events, and hospitalizations. The model estimated the annual medical cost of managing patients with hard-to-heal venous leg ulcers to be $20,041 for those treated with Graftskin and $27,493 for those treated with Unna's boot. In addition, treatment with Graftskin led to approximately 3 more months in the healed state per person per year than did treatment with Unna's boot. Because patients treated with Graftskin experienced improved healing compared with those treated with compression therapy using Unna's boot, they required fewer months of treatment for unhealed ulcers. As a result, the use of Graftskin for treating hard-to-heal venous leg ulcers resulted in lower overall treatment costs.
伤口护理领域最近的几项进展可能为治疗难愈合的下肢静脉溃疡带来希望。其中一种治疗方法是Apligraf(Graftskin),一种双层的活人体皮肤构建物。为了评估Graftskin的经济影响,构建了一个模型,以比较使用Graftskin治疗难愈合的下肢静脉溃疡与使用Unna靴进行压迫治疗的年度医疗成本和成本效益。使用半马尔可夫模型来描述下肢静脉溃疡患者的溃疡治疗、愈合和复发模式。患者接受两种治疗方案之一,即Graftskin或Unna靴,并在模型中随访12个月。分析是从商业健康保险计划的角度进行的;因此,只包括直接医疗成本。医疗资源的使用包括主要治疗干预、额外的压迫敷料、医生门诊、家庭健康访视、实验室检查和程序、不良事件管理以及住院治疗。该模型估计,使用Graftskin治疗难愈合的下肢静脉溃疡患者的年度医疗成本为20,041美元,而使用Unna靴治疗的患者为27,493美元。此外,与使用Unna靴治疗相比,使用Graftskin治疗每年每人的愈合状态大约多3个月。由于与使用Unna靴进行压迫治疗的患者相比,使用Graftskin治疗的患者愈合情况有所改善,他们未愈合溃疡所需的治疗月数更少。因此,使用Graftskin治疗难愈合的下肢静脉溃疡导致总体治疗成本更低。
