The purpose of this manuscript is to address a gap in our efforts to incrementally improve wound care practice through evidence-based practice. The Pressure Sore Status Tool (PSST) provides data to extend evidence-based practice beyond clinical trials and into the clinical area itself. The computerized PSST was evaluated over one year through over 70 beta sites. Two studies which were part of that evaluation period are described which give a comparative analysis of wound stage and PSST scores, and similarities and differences in wound characteristics of four types of wounds: arterial/ischemic ulcers, neuropathic ulcers, pressure ulcers, and venous ulcers. In the first study, a relationship between PSST scores and staging scores for the presenting wound was present, indicating promise for the utilization of the PSST as an alternative to staging scores for describing changes in wound status. However, in the second study, clear difference was not noticeable between the four wound types, suggesting that discriminations regarding wound type may not be able to be made from PSST assessments. The goal of these studies was to provide feedback on the use of the computerized PSST, thereby providing feedback based on objective outcomes of the practice of clinicians themselves.
本手稿的目的是填补我们在通过循证实践逐步改善伤口护理实践方面的努力中的一个空白。压疮状态工具（PSST）提供的数据可将循证实践从临床试验扩展到临床领域本身。通过70多个测试站点对计算机化的PSST进行了为期一年的评估。描述了作为该评估期一部分的两项研究，它们对伤口阶段和PSST评分进行了比较分析，并对四种伤口（动脉/缺血性溃疡、神经性溃疡、压疮和静脉溃疡）的伤口特征的异同进行了分析。在第一项研究中，呈现伤口的PSST评分与分期评分之间存在关联，这表明PSST有望作为描述伤口状态变化的分期评分的替代方法。然而，在第二项研究中，四种伤口类型之间没有明显差异，这表明可能无法通过PSST评估来区分伤口类型。这些研究的目的是提供关于计算机化PSST使用情况的反馈，从而根据临床医生自身实践的客观结果提供反馈。
