Abstract

OBJECTIVE

Wound dimensional assessments are important in determining the progress of a wound and the effect of interventions on wound healing. The FastSCAN (FS; Polhemus Inc, Colchester, Vermont) and Silhouette Mobile (SM; ARANZ Medical, Christchurch, New Zealand) are portable devices that quantify surface area, depth, and volume of wounds. This study evaluated their reliability in producing accurate wound measurements.

DESIGN AND SETTING

This study was conducted at the Waikato Hospital, Hamilton, New Zealand.

PATIENTS AND INTERVENTION

Eleven vascular patients with a combined total of 16 wounds underwent simultaneous wound measurements using three-dimensional computed tomography (CT) reconstruction, FS, and SM.

MAIN OUTCOME MEASURE

The validity of FS and SM was tested against CT. Additionally, the interoperator reliability and intraoperator reliability of FS and SM were determined.

MAIN RESULTS

The intraoperator reliability and interoperator reliability for volume recordings of the SM were 0.97 and 0.97, respectively, and for the FS were 0.96 and 0.97, respectively. The FS and SM measurements were not significantly different from CT. The SM consistently produced smaller wound volume and depth measurements compared with CT. In contrast, overestimation was observed for FS when compared with CT. However, the volume measurements in one wound were anomalous, being 10 times larger than CT measurements. Excluding this wound, there were strong correlations in wound volumes for SM and CT (r = 0.81; P ≤ .0001), for FS and CT (r = 0.99; P ≤ .001), and for SM and FS (r = 0.99; P ≤ .0001).

CONCLUSIONS

Measurements from FS and SM were comparable to CT. Therefore, SM and FS devices both offer the benefit of being noncontact portable devices that produce reproducible and reliable readings.

摘要

目的

伤口尺寸评估对于确定伤口的进展以及干预措施对伤口愈合的影响非常重要。FastSCAN（FS；Polhemus Inc，Colchester，Vermont）和 Silhouette Mobile（SM；ARANZ Medical，Christchurch，New Zealand）是两种可量化伤口表面积、深度和体积的便携式设备。本研究旨在评估它们在产生准确伤口测量值方面的可靠性。

设计和设置

本研究在新西兰汉密尔顿的怀卡托医院进行。

患者和干预措施

11 名血管病患者共有 16 处伤口，同时使用三维计算机断层扫描（CT）重建、FS 和 SM 进行了伤口测量。

主要观察指标

测试 FS 和 SM 的准确性。此外，还确定了 FS 和 SM 的操作者内和操作者间可靠性。

主要结果

SM 的体积记录的操作者内和操作者间可靠性分别为 0.97 和 0.97，FS 的分别为 0.96 和 0.97。FS 和 SM 的测量值与 CT 无显著差异。与 CT 相比，SM 始终产生较小的伤口体积和深度测量值。相比之下，FS 与 CT 相比存在高估。然而，一个伤口的体积测量值异常，是 CT 测量值的 10 倍。排除该伤口后，SM 和 CT（r = 0.81；P ≤.0001）、FS 和 CT（r = 0.99；P ≤.001）以及 SM 和 FS（r = 0.99；P ≤.0001）的伤口体积之间存在很强的相关性。
