数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

第一部分:病例报告表(CRF)—— 数据采集的蓝图 CRF是专门为该项研究设计的纸质或电子表格,用于在源点记录所有研究数据。它是整个研究数据质量的基石。 本研究的CRF包含以下模块: 1. 筛查与知情同意模块 · 患者筛查编号 · 知情同意书签署日期与版本 · 是否符合所有纳入标准(是/否) · 是否符合所有排除标准(是/否) 2. 基线资料模块 · 患者编号(代替姓名以保护隐私) · 人口统计学:性别、出生日期、年龄 · 疾病特征:病程、受累侧别、畸形类型(内翻/外翻)、Kellgren-Lawrence分级 · 基线评分:HSS评分、Lysholm评分、VAS评分 3. 手术与围术期模块 · 随机分组信息(治疗组/对照组) · 手术日期、手术开始与结束时间、手术总时长 · 术中出血量(mL) · 关节镜下发现与处理记录(复选框/文本描述): · 滑膜清理范围 · 软骨损伤分级及处理方式(微骨折等) · 半月板处理(缝合/部分切除) · 是否取出游离体 · 是否行外侧支持带松解 · 截骨相关记录(对照组:术中透视次数,矫正后力线角;治疗组:3D导板贴合情况) 4. 术后随访模块 · 术后首次下床时间 · 术后6周、3个月、6个月、12个月随访日期 · 各时间点的HSS评分、Lysholm评分、VAS评分 · 疗效评估(显效/有效/无效) · 并发症记录表: · 并发症类型(愈合不良、感染、下肢静脉血栓) · 发生日期 · 严重程度 · 与手术的关系 · 处理措施及结局 5. 数据质量签名 · 记录者签名与日期 · 核对者签名与日期 第二部分:电子数据采集(EDC)系统—— 数据管理的核心 EDC系统是一个安全的在线平台,研究人员将CRF上的数据录入其中,以便进行高效的管理、核查和分析。上图清晰地展示了数据从CRF录入到EDC系统,并通过核查质疑流程最终形成清洁数据库的路径。 在该研究中的EDC系统应用流程: 1. 系统构建与用户管理 · 研究数据库创建:根据CRF的设计,在EDC系统中构建相应的电子表格,设置变量类型(如数值、文本、日期、单选等)。 · 权限控制:为每位研究人员创建独立账户,并分配不同权限(如仅限数据录入、数据核查、数据管理等)。 2. 数据录入 · 研究人员按照CRF内容,将数据及时录入EDC系统。 · 系统可设置强制字段,确保关键数据不遗漏。 3. 数据核查——这是EDC系统的核心价值 · 自动逻辑核查:系统可预设核查规则,自动标记可疑数据。例如: · 范围核查:VAS评分录入为11分(应0-10分)。 · 逻辑核查:患者“术后下床时间”早于“手术结束时间”。 · 一致性核查:Kellgren-Lawrence分级为IV级的患者不应被纳入(根据排除标准)。 · 访视窗口核查:术后3个月随访日期不在规定时间窗内(如+/-2周)。 · 人工审核:数据管理员或主要研究者定期审查数据,对异常趋势或缺失数据提出疑问。 4. 数据质疑与管理 · 当系统或管理员发现问题时,会在EDC内向研究中心发出数据质疑。 · 研究中心的研究人员收到质疑后,必须核对原始病历和CRF,并在EDC系统中进行回复或修正。所有质疑和回复的记录都会被永久保存,形成完整的审计轨迹。 5. 数据锁定 · 在所有数据录入完成并通过核查、所有质疑均已解决之后,数据库将被锁定。 · 锁定的数据库将导出为统计格式(如.csv或.sav),用于最终的统计学分析。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Part I: Case Report Form (CRF) — The Blueprint for Data Collection The Common Report Format is a paper or electronic form specifically designed for this study, used to record all study data at the source. It serves as the cornerstone of the overall data quality for the entire study. The Common Report Format for this study includes the following modules: 1.Screening and Informed Consent Module Patient Screening Number Date and Version of Informed Consent Signature Whether all inclusion criteria are met (Yes/No) Whether all exclusion criteria are met (Yes/No) 2.Baseline Information Module Patient Number (instead of name to protect privacy) Demographics: Gender, Date of Birth, Age Disease Characteristics: Disease duration, Affected Side, Deformity Type (Varus/Valgus), Kellgren-Lawrence Grade Baseline Scores: HSS Score, Lysholm Score, VAS Score 3.Surgery and Perioperative Module Randomization Group Information (Treatment Group/Control Group) Surgery Date, Start and End Time of Surgery, Total Surgery Duration Intraoperative Blood Loss (mL) Arthroscopic Findings and Management Records (Checkboxes/Text Description): Scope of Synovectomy Cartilage Injury Grade and Treatment Method (e.g., Microfracture) Meniscus Management (Suture/Partial Resection) Whether Loose Bodies Were Removed Whether Lateral Retinaculum Release Was Performed Osteotomy-Related Records (Control Group: Number of Intraoperative Fluoroscopies, Corrected Mechanical Axis Angle; Treatment Group: 3D Guide Fit Status) 4.Postoperative Follow-up Module Time of First Ambulation Postoperatively Follow-up Dates at 6 Weeks, 3 Months, 6 Months, and 12 Months Postoperatively HSS Score, Lysholm Score, and VAS Score at Each Time Point Efficacy Evaluation (Markedly Effective/Effective/Ineffective) Complication Record Form: Type of Complication (Poor Healing, Infection, Lower Extremity Venous Thrombosis) Date of Occurrence Severity Relationship to Surgery Management Measures and Outcome 5.Data Quality Signatures Recorder's Signature and Date Verifier's Signature and Date Part II: Electronic Data Capture (EDC) System — The Core of Data Management The EDC system is a secure online platform where researchers enter data from the Common Report Form (CRF) for efficient management, verification, and analysis. The figure clearly illustrates the path of data from entry into the Common Report Form to the Electronic Data Center (EDC) system, through the query verification process, and finally forming a clean database. The application process of the EDC system in this study: 1.System Construction and User Management Study Database Creation: Based on the design of the Common Report Form, corresponding electronic spreadsheets are created in the Electronic Data Center system, with variable types set (e.g., numeric, text, date, single choice). Permission Control: Independent accounts are created for each researcher, with different permissions assigned (e.g., limited to data entry, data verification, data management). 2.Data Entry Researchers enter data into the Electronic Data Capture (EDC) system in a timely manner according to the content of the Common Report Form. The system can set mandatory fields to ensure critical data is not omitted. 3.Data Verification — This is the core value of the Electronic Data Center (EDC) system Automatic Logical Verification: The system can preset verification rules to automatically flag suspicious data. For example: Range Check: A service score entered as 11 (should be 0-10). Logical Check: A patient's "Postoperative Ambulation Time" is earlier than "Surgery End Time". Consistency Check:Patients with a Kellgren-Lawrence grade IV should not be included (based on exclusion criteria). Window verification: The postoperative 3-month follow-up date falls outside the specified time window (e.g., +/-2 weeks). Manual review: Data administrators or principal investigators regularly review the data, raising questions about abnormal trends or missing data. 4. Data Challenge and Management When the system or administrator identifies an issue, a data challenge will be issued to the research center within the EDC. Upon receiving a query, the researchers at the research center must verify the original medical records and CRF, and respond or correct them in the EDC system. All records of queries and responses will be permanently retained, forming a complete audit trail. 5.Data Lockdown The database will be locked after all data entry is completed and verified, and all questions have been resolved. Locked databases will be exported in statistical formats (e.g.,.csv or.sav) for final statistical analysis.
