随机方法(请说明由何人用什么方法产生随机序列):

采用区组随机化方法,以入院时间划分区组,区组长度4或6随机交替。由不参与临床研究的统计人员使用Research Randomizer软件生成随机序列,分配方案置于密封、不透光、按序编号的信封中,由研究护士在确认患者入组后,严格按入组顺序依次拆封。

Randomization Procedure (please state who generates the random number sequence and by what method):

Block randomization will be used, with block sizes of 4 or 6 randomly alternated based on admission time. A statistician not involved in the clinical study will generate the random sequence using Research Randomizer software. The allocation sequence will be placed in sealed, opaque, sequentially numbered envelopes. Research nurses will open the envelopes in strict order of enrollment after confirming eligibility and obtaining informed consent.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

由于干预措施为健康教育推送,无法对受试者和干预实施者设盲。本研究采用评估者盲和统计师盲:指定2名不参与分组与干预实施的研究护士作为专职结局评估者,独立完成各时间点评估,不询问分组情况;数据交由不知分组信息的统计师分析。

Blinding:

Due to the nature of the intervention (health education delivery), blinding of participants and intervention providers is not feasible. This study employs assessor blinding and statistician blinding: two designated research nurses not involved in allocation or intervention will independently perform outcome assessments without knowledge of group assignment. Data will be analyzed by a statistician blinded to group allocation.

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:

采用纸质病例记录表(CRF)收集问卷数据,由经过统一培训的研究护士在各评估时间点(基线、术后第4周、术后第12周)完成PG-SGA、FACT-G、GSRS等量表的评估与填写。实验室数据(白蛋白、前白蛋白等)从医院信息系统(HIS)直接导出。所有纸质问卷在收集后24小时内由双人独立录入Excel数据库并进行一致性核对。电子数据存储于加密的专用研究电脑,仅研究团队核心成员可访问。患者身份信息采用研究编号进行匿名化处理,身份信息与编号的对应表单独加密保存。

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

Data will be collected using paper Case Record Forms (CRF). Research nurses trained uniformly will complete the PG-SGA, FACT-G, and GSRS assessments at each evaluation time point (baseline, postoperative week 4, and postoperative week 12). Laboratory data (albumin, prealbumin, etc.) will be directly exported from the Hospital Information System (HIS). All paper questionnaires will be independently entered into an Excel database by two researchers within 24 hours of collection, with consistency checks. Electronic data will be stored on an encrypted, dedicated research computer accessible only to core research team members. Patient identity will be anonymized using study codes, and the code-identity linkage file will be stored separately with encryption.
