The BORDER III trial found that five-layer silicone border dressings effectively prevented pressure injuries in long-term care, but the value of this approach is unknown. Our objective was to analyse the cost-effectiveness of preventing facility-acquired pressure injuries with a quality improvement bundle, including prophylactic five-layer dressings in US and Australian long-term care. Markov models analysed the cost utility for pressure injuries acquired during long-term care from US and Australian perspectives. Models calibrated outcomes for standard care compared with a dressing-inclusive bundle over 18 monthly cycles or until death based on BORDER III outcomes. Patients who developed a pressure injury simulated advancement through stages 1 to 4. Univariate and multivariate probabilistic sensitivity analyses tested modelling uncertainty. Costs in 2017 USD and quality-adjusted life years (QALYs) were used to calculate an incremental cost-effectiveness ratio (ICER). Dressing use yielded greater QALYs at slightly higher costs from perspectives. The US ICER was $36 652/QALY, while the Australian ICER was $15 898/QALY, both of which fell below a willingness-to-pay threshold of $100 000/QALY. Probabilistic sensitivity analysis favoured dressings as cost-effective for most simulations. A quality improvement bundle, including prophylactic five-layer dressings, is a cost-effective approach for pressure injury prevention in all US and Australia long-term care residents.
BORDER III 试验发现,五层硅胶边缘敷料能有效预防长期护理中的压力性损伤,但这种方法的价值尚不清楚。我们的目的是分析在美国和澳大利亚的长期护理中,使用质量改进包预防机构获得性压力性损伤的成本效益,其中包括预防性的五层敷料。Markov 模型从美国和澳大利亚的角度分析了长期护理中获得的压力性损伤的成本效用。模型根据 BORDER III 的结果,对标准护理与包括敷料在内的护理包进行了 18 个月或直至死亡的比较校准。出现压力性损伤的患者模拟进入 1 到 4 期。单变量和多变量概率敏感性分析测试了模型的不确定性。2017 年美元和质量调整生命年(QALY)的成本用于计算增量成本效益比(ICER)。从两个角度来看,敷料的使用在略微增加成本的情况下产生了更多的 QALYs。美国的 ICER 为 36652 美元/QALY,澳大利亚的 ICER 为 15898 美元/QALY,均低于 10 万美元/QALY 的支付意愿阈值。概率敏感性分析倾向于认为敷料在大多数模拟中具有成本效益。包括预防性五层敷料在内的质量改进包是预防美国和澳大利亚所有长期护理居民压力性损伤的一种具有成本效益的方法。
