The number of ostomy care clinician experts is limited and the majority of ostomy care is provided by non-specialized clinicians or unskilled caregivers and family. The purpose of this study was to obtain content validation data for a new standardized algorithm for ostomy care developed by expert wound ostomy continence nurse (WOCN) clinicians. After face validity was established using overall review and suggestions from WOCN experts, 166 WOCNs self-identified as having expertise in ostomy care were surveyed online for 6 weeks in 2009. Using a cross-sectional, mixed methods study design and a 30-item instrument with a 4-point Likert-type scale, the participants were asked to quantify the degree of validity of the Ostomy Algorithm's decisions and components. Participants' open-ended comments also were thematically analyzed. Using a scale of 1 to 4, the mean score of the entire algorithm was 3.8 (4 = relevant/very relevant). The algorithm's content validity index (CVI) was 0.95 (out of 1.0). Individual component mean scores ranged from 3.59 to 3.91. Individual CVIs ranged from 0.90 to 0.98. Qualitative data analysis revealed themes of difficulty associated with algorithm formatting, especially orientation and use of the Studio Alterazioni Cutanee Stomali (Study on Peristomal Skin Lesions [SACS™ Instrument]) and the inability of algorithms to capture all individual patient attributes affecting ostomy care. Positive themes included content thoroughness and the helpful clinical photos. Suggestions were offered for algorithm improvement. Study results support the strong content validity of the algorithm and research to ascertain its construct validity and effect on care outcomes is warranted.
造口护理临床专家的数量有限，大多数造口护理由非专业临床医生或无技能的护理人员及家属提供。本研究的目的是获取由伤口造口失禁专科护士（WOCN）临床专家开发的一种新的造口护理标准化算法的内容效度数据。在通过WOCN专家的全面审查和建议确立表面效度后，2009年对166名自称在造口护理方面有专业知识的WOCN进行了为期6周的在线调查。采用横断面混合方法研究设计和一个有30个项目、采用4点李克特量表的工具，要求参与者对造口算法的决策和组成部分的效度程度进行量化。还对参与者的开放式评论进行了主题分析。使用1至4的量表，整个算法的平均得分为3.8（4 = 相关/非常相关）。该算法的内容效度指数（CVI）为0.95（满分1.0）。各个组成部分的平均得分在3.59至3.91之间。各个CVI在0.90至0.98之间。定性数据分析揭示了与算法格式相关的困难主题，特别是《皮肤造口改变研究》（SACS™工具）的定位和使用，以及算法无法涵盖所有影响造口护理的个体患者特征。积极的主题包括内容的全面性和有用的临床照片。针对算法改进提出了建议。研究结果支持该算法具有很强的内容效度，有必要进行研究以确定其结构效度及其对护理结果的影响。
