研究目的:

本研究旨在利用 AI 系统分析临床样本,为临床抢救危重真菌感染患者提供快速可靠的菌学依据,最终形成一套可复制的、数字化、标准化的真菌快速筛查临床路径,证明“荧光+AI”模式的有效性。  

Objectives of Study:

This study aims to utilize an AI system for analyzing clinical samples, so as to provide rapid and reliable mycological evidence for the emergency management of critically ill patients with fungal infections. Ultimately, it seeks to establish a reproducible, digitalized, and standardized clinical pathway for rapid fungal screening, thereby demonstrating the effectiveness of the combined fluorescence‑staining and AI approach.

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:

病例报告表/电子数据记录 在研究开始前,根据纸质版病例报告表内容建立Redcap电子数据库/EDC数据库。 数据管理 原始数据应统一记录在研究病历中,根据研究病历内容,可由研究者本人或指定/授权接受过培训的人员完成病例报告表填写及电子数据库的数据录入,确保信息的完整性和准确性。为保证数据的准确性,研究者每年进行不少于2次自查,定期委派人员到分中心进行项目质控,并接受医院、学校管理部门的检查。若发现病例报告表/电子数据库中登记的数据与原始记录(研究病历)不一致时,研究者应组织及时核实数据,对有误的部分按GCP法规要求进行修改,必要时应作相应说明。 系统中所有数据疑问解决后,由主要研究者、统计分析人员和数据管理人员召开审核会议,确定分析数据集,并对审核后的数据进行锁定,锁定后的数据文件不再做改动。如数据库锁定之后发现的问题如需修改,应严格按照解锁和再锁定的流程,进行数据的修改。

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

Data collection and Management:Case Report Form (CRF)/Electronic Data Capture (EDC) Prior to study initiation, an electronic database (REDCap database/EDC database) will be established based on the content of the paper Case Report Form (CRF). Data Management Source data should be uniformly recorded in the source documents (study medical records). Based on the source documents, the investigator or designated/authorized, trained personnel may complete the paper CRF and enter data into the electronic database, ensuring the completeness and accuracy of the information. To ensure data accuracy, the investigator will conduct self-audits no less than twice per year. Personnel will be periodically dispatched to sub-centers for project quality control, and the study will undergo inspections by hospital and institutional authorities. If discrepancies are identified between data recorded in the CRF/electronic database and the source documents (study medical records), the investigator must promptly organize data verification. Any erroneous parts must be corrected in accordance with GCP regulations, with corresponding explanations provided as necessary. After all data queries in the system are resolved, the Principal Investigator (PI), statistical analyst, and data manager will convene a review meeting to finalize the analysis dataset. The reviewed data will then be locked; once locked, the data files will not be altered. If issues requiring modification are discovered after database lock, data changes must be performed strictly following the formal procedures for unlocking and relocking the database.
