研究目的: |
构建并验证基于术前肺功能指标、CT 三维定量指标及 EIT 指标等多因素预测模型,明确三大板块指标对 VATS 患者术后肺不张的预测价值,为术前风险分层及预防提供参考。以 CT 为金标准,评价术后 EIT 指标与 CT 结果在肺不张评估中的相关性和评价一致性,明确 EIT 用于 VATS 患者术后肺不张筛查的可行性。 |
||||||||||||||||||||||
|
Objectives of Study: |
Construct and validate a multi-factor prediction model based on preoperative pulmonary function indicators, CT three-dimensional quantitative indicators, and EIT indicators, clarify the predictive value of the three major indicators for postoperative atelectasis in VATS patients, and provide a reference for preoperative risk stratification and intervention. Using CT as the gold standard, evaluate the correlation and consistency of postoperative EIT indicators and CT results in the assessment of atelectasis, and clarify the feasibility of using EIT for screening and monitoring of postoperative atelectasis in VATS patients. |

||||||||||||||||||||||
|
Exclusion criteria: |
1. Emergency surgery; 2. Pre-existing atelectasis or clinically significant pulmonary conditions that may substantially affect pulmonary function and imaging assessment (e.g., severe pulmonary infection, pleural effusion, pneumothorax); 3. Severe dysfunction of major organs such as the heart, liver, or kidneys; 4. Psychiatric disorders, cognitive impairment, or other conditions preventing completion of the relevant examinations; 5. Missing clinical records, imaging data, or test results that fail to meet analysis requirements; 6. Conversion to open thoracotomy during surgery. |

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
The de-identified raw research data shall be completely uploaded and publicly disclosed within 6 months after the completion of full data cleaning, statistical analysis, finalization and formal publication of the research results. If the study involves achievement transformation or subsequent extended analysis, the data sharing deadline may be appropriately extended, but the total extension period shall not exceed 12 months after the completion of the study, and the reason for extension shall be noted on the clinical trial registration platform simultaneously.The de-identified data is planned to be shared on the National Population Health Science Data Center (Special Zone for Clinical Medical Research), with the official public URL: https://www.ncmi.cn. |

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: |
本研究为回顾性研究,数据来源于医院信息系统的既往资料,包括电子病历(HIS)、影像系统(PACS)、EIT数据导出平台等。由研究人员按预设变量表进行提取与录入,采用唯一研究编号替代姓名与住院号,建立“身份识别表”与“研究数据库”分离存放。数据录入后进行双人核对与逻辑检查(范围值、缺失值、异常值),必要时回溯原始记录更正。电子数据存储于单位受控电脑/服务器并加密、设置访问权限与密码,定期备份;纸质资料(如有)置于上锁柜中。数据仅用于本研究分析与学术发表,以汇总形式报告,不公开任何可识别个人信息;保存期限按单位要求执行,期满按规定销毁或继续留存用于审计/复核。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
This is a retrospective study. Data will be extracted from existing hospital information systems, including the electronic medical record/HIS, the picture archiving and communication system (PACS), and the EIT data export platform. Trained study personnel will extract and enter data according to a predefined variable list. A unique study ID will be used to replace personal identifiers (e.g., name and medical record number), and the “linkage file” (identifier key) will be stored separately from the analytic dataset. After data entry, a two-person verification and logic checks (range checks, missing values, and outliers) will be performed, with source data verification and correction when necessary. Electronic data will be stored on institution-controlled computers/servers with encryption, password protection, and role-based access control, and will be backed up regularly; paper records (if any) will be kept in a locked cabinet. Data will be used solely for analysis and academic publication, reported only in aggregate, and no identifiable personal information will be disclosed. Data will be retained in accordance with institutional requirements and, upon expiration, will be destroyed per policy or retained for audit/verification as required. |
