Dataset for "Evidence-Performance Gaps in Knee Osteoarthritis Care Pathways in Switzerland. A Cross-Sectional Study Using Patient-Reported Data"

This dataset was generated within the research project “Evidence-Performance Gaps in Knee Osteoarthritis Care Pathways in Switzerland. A Cross-Sectional Study Using Patient-Reported Data.” The study investigated the different care pathways of patients with knee osteoarthritis (KOA) in Switzerland and how these align with international, clinical guideline recommendations. Data collection and participantsA cross-sectional online survey was conducted between December 2023 and April 2024. A total of 1,659 responses were received; after applying predefined inclusion and exclusion criteria, 1,410 participants were included in the final analysis. Respondents were grouped into three subpopulations: individuals participating in a structured exercise programme, patients after total knee arthroplasty (TKA), and patients receiving individual conservative care. Dataset versionsTwo versions of the dataset are provided in CSV format (UTF-8): Raw dataset: contains all 1,659 responses, including cases that were later excluded. Cleaned dataset: contains 1,410 valid responses after exclusion criteria were applied. Both datasets have been fully anonymised: direct identifiers (e.g. record ID, survey identifiers, timestamps) were removed, and indirect identifiers were minimised (e.g. year of birth excluded, only age included). As the data were collected anonymously, no ethics committee approval was required. Supporting documentation A README file describing the dataset structure and anonymisation process. A translated English version of the questionnaire and codebook.本数据集源自研究项目《瑞士膝骨关节炎（knee osteoarthritis, KOA）护理路径的证据-绩效差距：基于患者报告数据的横断面（cross-sectional）研究》。该研究针对瑞士膝骨关节炎患者的各类护理路径展开调研，旨在明确其与国际临床指南推荐方案的契合程度。 ### 数据收集与研究对象 本研究于2023年12月至2024年4月期间开展横断面线上调查，共回收1659份问卷回复。经预设的纳入与排除标准筛选后，最终纳入1410名参与者进行最终分析。受访者被划分为三个亚群体：参与结构化运动计划的个体、接受全膝关节置换术（total knee arthroplasty, TKA）的患者，以及接受个体化保守治疗的患者。 ### 数据集版本 本数据集提供两种UTF-8编码的CSV格式版本： 1. 原始数据集：包含全部1659份问卷回复，涵盖后续被剔除的案例。 2. 清洗后数据集：经排除标准筛选后的1410份有效回复。 所有数据集均已完成完全匿名化处理：直接识别标识符（如记录ID、问卷标识、时间戳）已被移除，间接识别标识符已做最小化处理（如剔除出生年份，仅保留年龄信息）。由于本数据采用匿名收集方式，无需获得伦理委员会批准。 ### 辅助文档 包含以下资料： 1. 说明文档：详述数据集结构与匿名化流程。 2. 问卷与编码手册的英文译本。
