Abstract

Background: This Delphi study aimed to develop the Observer Scale of the Patient and Observer Scar Assessment Scale (POSAS) 3.0 for measurements of scar quality in patients with all types of scars. The POSAS 3.0 Patient Scale has been developed using an extensive qualitative study, which has been published separately.

Methods: An online, 3-round Delphi study was performed with 124 international scar experts from 23 countries spanning 7 continents. Panelists rated their (dis)agreement with proposals regarding the wording and relevance of scar characteristics on a 5-point scale ("strongly disagree" to "strongly agree"), and provided arguments for their decisions. Consensus was reached if ≥67% of the panelists agreed or strongly agreed to a proposal.

Results: Consensus was reached on the inclusion of 9 items. Two versions of the Observer Scale of the POSAS 3.0 have been developed, 1 generic version including 7 items, and 1 linear scar version, containing the same 7 items and 2 additional scar-specific items.

Conclusions: This is the first study using the Delphi process to develop an instrument for the assessment of scars. Panelists from all over the world reached a consensus on the content of 2 versions of the Observer Scale, the generic version and the linear scar version. By involving the potential end-user community of the new POSAS version in its development, we expect the developed instrument to have high content validity. For a comprehensive scar assessment, the Observer Scale should be used in combination with the Patient Scales of the POSAS 3.0.

病人观察量表和疤痕观察量表的发展：一项国际德尔菲研究。

背景：本德尔菲研究旨在开发患者观察量表和观察疤痕评估量表（POSAS） 3.0，用于测量所有类型疤痕患者的疤痕质量。POSAS 3.0患者量表是通过广泛的定性研究制定的，已单独发表。方法：对来自7大洲23个国家的124名国际疤痕专家进行了一项在线的3轮德尔菲研究。小组成员以5分制（“非常不同意”到“非常同意”）对关于疤痕特征的措辞和相关性的建议进行了（不同意）评级，并为他们的决定提供了论据。如果≥67%的专家组成员同意或强烈同意一项提案，则达成共识。结果：对纳入的9个项目达成共识。POSAS 3.0的观察者量表有两个版本，一个是通用版本，包括7个项目，一个是线性疤痕版本，包含相同的7个项目和2个额外的疤痕特定项目。结论：这是第一个使用德尔菲法开发疤痕评估工具的研究。来自世界各地的小组成员就观察员量表的2个版本，通用版和线性疤痕版的内容达成了共识。通过让新POSAS版本的潜在最终用户社区参与其开发，我们期望开发的工具具有高内容效度。为了进行全面的疤痕评估，应结合POSAS 3.0的患者量表使用观察者量表。

期刊介绍： Plastic and Reconstructive Surgery—Global Open is an open access, peer reviewed, international journal focusing on global plastic and reconstructive surgery.Plastic and Reconstructive Surgery—Global Open publishes on all areas of plastic and reconstructive surgery, including basic science/experimental studies pertinent to the field and also clinical articles on such topics as: breast reconstruction, head and neck surgery, pediatric and craniofacial surgery, hand and microsurgery, wound healing, and cosmetic and aesthetic surgery. Clinical studies, experimental articles, ideas and innovations, and techniques and case reports are all welcome article types. Manuscript submission is open to all surgeons, researchers, and other health care providers world-wide who wish to communicate their research results on topics related to plastic and reconstructive surgery. Furthermore, Plastic and Reconstructive Surgery—Global Open, a complimentary journal to Plastic and Reconstructive Surgery, provides an open access venue for the publication of those research studies sponsored by private and public funding agencies that require open access publication of study results. Its mission is to disseminate high quality, peer reviewed research in plastic and reconstructive surgery to the widest possible global audience, through an open access platform. As an open access journal, Plastic and Reconstructive Surgery—Global Open offers its content for free to any viewer. Authors of articles retain their copyright to the materials published. Additionally, Plastic and Reconstructive Surgery—Global Open provides rapid review and publication of accepted papers.
