研究目的: |
1.接受了结直肠癌切除术的患者,将患者分为吻合口漏组和无吻合口漏组,比较两组患者人口特征、术后PCT的差异。 2.基于多种机器学习,运用患者人口特征联合术后第2天/术后第3天/术后第2+3天PCT构建预测吻合口漏模型。 |
||||||||||||||||||||||
|
Objectives of Study: |
1.Patients who underwent colorectal resection were divided into an anastomotic leakage group and a non-anastomotic leakage group. The demographic characteristics and postoperative procalcitonin (PCT) levels were compared between the two groups. 2.Using multiple machine learning algorithms, predictive models for anastomotic leakage were developed and constructed based on patient demographic characteristics combined with PCT levels on postoperative day 2, postoperative day 3, and both postoperative days 2 and 3. |

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: |
(一)数据记录 1.研究者必须保证数据真实、完整、准确。2.研究者在入组研究参与者后及时填写病例报告表或临床研究数据记录表,保证病例报告表或临床研究数据记录表上的内容与病历内容一致。3.研究者记录做任何更正时只能划线,旁注改后的数据,由研究者签名并注明日期,不得擦涂、覆盖原始记录。4.实验室检查项目齐全且均可溯源。5.每例研究参与者数据收集结束后,研究者应及时填写好病例报告表或临床研究数据记录表上相关数据,并交本中心主要研究者审核、签名确认。 (二)数据管理 1. 数据的临床研究数据记录表的填写与移交 原始记录(原始病历、检查报告单等)需妥善保存。临床研究数据记录表的数据均来源于原始病历,由研究者填写,每个入选获得编码的病例必须完成临床研究数据记录表。完成的临床研究数据记录表由主要研究者审查后交数据管理员,进行数据录入与管理工作。 2. 数据库的设计及建立 建立临床研究数据库,记录CRF表中所有的信息。数据库的格式将尽量与CRF表的格式相对应以方便录入的进行。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1. Data Recording (1).Researchers must ensure that the data is true, complete and accurate. (2). After enrolling the research participants, the researchers should promptly fill out the case report form or the clinical research data record form to ensure that the contents on the case report form or the clinical research data record form are consistent with the medical records. (3). When researchers make any corrections to their records, they can only underline the modified data, annotate it with the researcher's signature and date, and must not erase or cover the original records. (4). The laboratory inspection items are complete and all can be traced. (5). After the data collection for each study participant is completed, the researcher should promptly fill in the relevant data on the case report form or clinical research data record form and submit it to the principal researcher of this center for review and signature confirmation. 2.Data Management (1). Filling in and transferring the clinical research data record form Original records (such as original medical records, examination reports, etc.) should be properly kept. The data in the clinical research data record form are all derived from the original medical records and filled in by the researchers. Each case that is selected and encoded must complete the clinical research data record form. The completed clinical research data record form is reviewed by the principal investigator and then submitted to the data administrator for data entry and management. (2). Database design and establishment Establish a clinical research database and record all the information in the CRF form. The format of the database will correspond as much as possible to that of the CRF table to facilitate the input process. |
