The increasing demand for skin quality interventions in aesthetic medicine underscores the necessity for objective, evidence-based assessment tools that may be used to evaluate novel interventions or devices.
To develop and validate a 5-point photonumeric rating scale for assessing overall skin quality, including radiance, color evenness, and smoothness.
The IBSA (Institut Biochimique SA) Composite Skin Quality Scale was developed and underwent live validation with 88 real-world patients, chosen to encompass a broad spectrum of skin qualities and Fitzpatrick skin types. Scale validation was performed by board-certified plastic surgeons and dermatologists over 2 rounds, 2 weeks apart. Reliability was assessed through intrarater and interrater agreements, utilizing weighted kappa statistics and intraclass correlation coefficient (ICC). The scale's ability to discern a clinically relevant 1-grade difference was evaluated with 72 photo pairs.
Combined intrarater reliability results showed weighted kappa values of 0.812 (right side) and 0.815 (left side) and an ICC of 0.903 for both sides, indicating an almost perfect agreement. Interrater reliability ranged from substantial to almost perfect, with kappa coefficients between 0.654 and 0.853 and ICCs between 0.657 and 0.855 across all rater pairs in both rounds. The ability to detect a clinically relevant 1-point difference using the scale was established.
Integrating various key aspects of skin quality, the IBSA Composite Skin Quality Scale is a clinically relevant and highly reliable tool, suitable for skin assessment in clinical studies of new aesthetic technologies and products.
美容医学中对皮肤质量干预措施的需求不断增加，凸显了使用客观、循证评估工具来评估新型干预措施或设备的必要性。
开发并验证一种用于评估整体皮肤质量（包括光泽度、颜色均匀度和平滑度）的5分数字评分量表。
开发了IBSA（生物化学研究所SA）综合皮肤质量量表，并在88名真实患者中进行了现场验证，这些患者涵盖了广泛的皮肤质量和Fitzpatrick皮肤类型。量表验证由获得委员会认证的整形外科医生和皮肤科医生分两轮进行，两轮间隔2周。通过评分者内和评分者间的一致性评估可靠性，使用加权kappa统计量和组内相关系数（ICC）。用72对照片评估该量表辨别临床上相关的1级差异的能力。
综合评分者内可靠性结果显示，加权kappa值右侧为0.812，左侧为0.815，两侧的ICC均为0.903，表明几乎完全一致。评分者间可靠性从高度一致到几乎完全一致，两轮中所有评分者对的kappa系数在0.654至0.853之间，ICC在0.657至0.855之间。确定了使用该量表检测临床上相关的1分差异的能力。
IBSA综合皮肤质量量表整合了皮肤质量的各个关键方面，是一种临床相关且高度可靠的工具，适用于新美容技术和产品临床研究中的皮肤评估。
