Objectives of Study:

Primary Objective: To evaluate the efficacy of Saccharomyces boulardii in the prevention of antibiotic-associated diarrhea (AAD) in children. Secondary Objectives: To evaluate the safety of Saccharomyces boulardii in the prevention of AAD in children; To analyze the efficacy of Saccharomyces boulardii sachets in the prevention of pediatric antibiotic-associated diarrhea (AAD) among different pediatric subgroups (classified by types of antibiotics, routes of administration, combined use of antibiotics, etc.). Exploratory Objectives: To explore the differential gut microbiota characteristics that influence the preventive effect of Saccharomyces boulardii on AAD in children; To explore the effects of Saccharomyces boulardii on the diversity, abundance, and gene expression changes of the gut microbiota in children; To explore the effects of Saccharomyces boulardii on intestinal metabolism in children; To investigate the relationship between the clinical symptoms of pediatric antibiotic-associated diarrhea (AAD) and changes in the gut microbiota.

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:

1.数据采集 本研究的数据采集以病例记录表(Case Record Form, CRF) 为核心工具。CRF 由研究者根据试验方案设计,涵盖受试者基线资料(性别、年龄、疾病史、用药史等)、入组筛选信息、治疗过程记录(干预措施、用药依从性等)、疗效指标(腹泻发生率、持续时间、肠道菌群多样性等)、安全性指标(不良事件、严重不良事件发生情况)及实验室检测结果(粪便微生物组测序、代谢组学分析数据)等模块。 依据CRF生成电子CRF,即eCRF。研究者/临床协调员在EDC系统中按照及时、准确、完整、规范的原则进行eCRF填报。 2.数据管理 本研究采用电子数据采集和管理系统(Electronic Data Capture, EDC)进行数据的电子化录入、核查与管理。 包括 CRF 电子化构建、在线数据录入、逻辑核查(内置预设逻辑规则,自动识别矛盾数据)、数据疑问沟通与解答、数据锁定与导出等功能。

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

Data Collection The core tool for data collection in this study is the Case Record Form (CRF). Designed by the investigators in accordance with the trial protocol, the CRF covers the following modules: subjects' baseline data (gender, age, medical history, medication history, etc.), enrollment screening information, treatment process records (interventions, medication compliance, etc.), efficacy indicators (incidence and duration of diarrhea, intestinal microbiota diversity, etc.), safety indicators (occurrence of adverse events and serious adverse events), and laboratory test results (fecal microbiome sequencing, metabolomics analysis data, etc.). An electronic Case Record Form (eCRF) will be generated based on the CRF. Investigators/clinical research coordinators (CRCs) shall complete the eCRF in the Electronic Data Capture (EDC) system in accordance with the principles of timeliness, accuracy, completeness and standardization. Data Management This study adopts an Electronic Data Capture (EDC) system for electronic data entry, verification and management. The system is equipped with the following functions: electronic CRF development, online data entry, logical verification (with built-in preset logic rules to automatically identify contradictory data), communication and resolution of data queries, and data locking and export.
