After patients receive autologous hematopoietic stem cell reinfusion, blood routine tests are perfor

Measure method:

Body temperature is measured using an electronic thermometer, and the occurrence of febrile neutropenia is determined based on blood routine results.

Outcome:

Incidence of febrile neutropenia

Type:

Primary indicator

测量时间点:

自体造血干细胞回输后,每隔一天进行血常规化验,每天至少测量4次体温

测量方法:

采用体温计测量体温,抽取血常规判断是否发生粒缺。粒缺指外周血中性粒细胞绝对计数(ANC)<0.5×109/L,或预计 48 h 后 ANC<0.5×109 /L;严重粒缺指ANC<0.1×109 /L。发热指指单次腋温≥38.0℃,或腋温≥37.7℃持续超过 1h。粒缺伴发热的发生率=各组发热例数/各组总例数

Measure time point of outcome:

After patients receive autologous hematopoietic stem cell reinfusion, blood routine tests are perfor

Measure method:

Body temperature is measured using a thermometer, and neutropenia is determined based on blood routine results. Neutropenia is defined as an absolute neutrophil count (ANC) in peripheral blood < 0.5×10?/L, or an anticipated ANC < 0.5×10?/L within 48 hours. Severe neutropenia is defined as ANC < 0.1×10?/L. Fever is defined as a single axillary temperature ≥ 38.0°C, or axillary temperature ≥ 37.7°C lasting more than 1 hour. The incidence of febrile neutropenia is calculated as the number of febril

随机方法(请说明由何人用什么方法产生随机序列):

由联络员将区组长度定为 4,具体步骤:采用 Excel 中 Rand 函数生成 0-1 之间均匀分布的随机数,将其复制至 Excel 另一行中生成随机数字 1,将每个区组中的随机数字由小到大排列,得到序号 R,R1-R2 为 试验组,R3 到 R4 为对照组。

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

The randomization sequence was generated by the study coordinator using the RAND() function in Microsoft Excel software to produce uniformly distributed random numbers between 0 and 1. For each block of length 4, four random numbers were generated and sorted in ascending order, resulting in a sorting rank R (1 to 4) within each block. The first two subjects (R1, R2) in each block were assigned to the experimental group (low bacterial diet group), and the last two (R3, R4) were assigned to the control group (aseptic diet group). The generation of the randomization sequence was performed independently by the study coordinator, and the allocation was concealed

本研究的数据采集包括:患者人口学信息、临床特征、饮食干预记录、每日体温测量值、血常规结果、感染事件(粒缺伴发热、血培养阳性、大便培养阳性等)、腹泻发生情况、住院时长及体重变化等。所有数据由研究协调员使用电子病例报告表(eCRF)进行双人独立录入,并定期与原始病历核对以确保准确性。数据管理采用密码保护的数据库,仅授权研究人员可访问。数据将保存至研究结束后的10年

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

Data collected in this study include demographic information, clinical characteristics, dietary intervention records, daily temperature measurements, blood routine results, infectious events (febrile neutropenia, positive blood culture, positive stool culture, etc.), occurrence of diarrhea, length of hospital stay, and body weight changes. All data will be double-entered independently by study coordinators using an electronic case report form (eCRF) and regularly verified against source medical records to ensure accuracy. Data management will be performed using a password-protected database accessible only to authorized research personnel. Data will be retained for 10 years after study completion.
