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。以社区卫生服务中心为分层因素(本街道仅一家中心,分层后仅一层),在该层内采用区组随机化,区组长度随机变化(4或6),按1:1比例将社区分配至混合干预组和常规服务对照组。最终分配结果为干预组6个社区、对照组5个社区。随机序列由不参与现场招募的统计师使用R软件(版本4.3,设置随机种子)生成。

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

Block randomization method was adopted. The community health service center was taken as the stratification factor (there is only one center in this sub-district, leaving only one stratum after stratification). Within this stratum, block randomization was applied with randomly varied block sizes (4 or 6). Communities were allocated to the combined intervention group and the routine service control group at a 1:1 ratio. The final allocation resulted in 6 communities in the intervention group and 5 communities in the control group. The random sequence was generated by a statistician not involved in on-site recruitment using R software (Version 4.3, with a random seed set).

盲法:

本研究为开放标签设计,干预实施者和受试者均知晓分组。但结局指标评估采用盲法:从免疫规划信息系统提取接种记录的数据管理员和进行统计分析的分析师,在数据锁定和分析完成前均不知晓社区分组归属。

Blinding:

This study adopts an open-label design, in which both intervention implementers and participants are aware of the group allocation. However, blinding is applied to the evaluation of outcome indicators: data administrators who extract vaccination records from the immunization information system and analysts conducting statistical analysis remain unaware of the community group assignments until data locking and analysis are completed.

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:

数据采集:本研究通过“浙江省免疫规划信息系统”获取研究对象的流感疫苗接种记录。数据采集由经过培训的研究助理负责,采用盲法提取(提取人员不参与分组过程),确保数据的客观性。采集的内容包括:目标社区6-35月龄婴幼儿的流感疫苗接种状态(是否接种、接种剂次、接种日期)及基本人口学信息(性别、月龄、居住社区)。过程监控数据(短信平台推送成功率、点击率,社区医生结构化推荐扫码记录)由系统自动生成并导出。 数据管理:(1)数据存储:所有电子数据存储于医院的加密服务器中,仅课题组成员可凭授权账号访问。纸质材料(如问卷纪录、扫码登记表)存放于上锁的文件柜中。(2)数据保密:所有数据去除个人身份标识(姓名、身份证号、家庭住址等),仅以研究ID编号进行识别。数据导出和处理过程中严格保护参与者隐私。(3)数据使用:数据仅用于本研究所述的科学目的,不用于其他商业用途或未经批准的二次研究。(4)数据期限:研究结束后,数据将保存5年,期满后将按医院规定进行匿名化处理或销毁。

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

Data Collection: This study obtained influenza vaccination records of research subjects through the "Zhejiang Provincial Immunization Planning Information System". Data collection was undertaken by trained research assistants with blinded extraction (extractors did not participate in the grouping process) to ensure the objectivity of the data. The collected information included the influenza vaccination status (vaccination status, number of doses, vaccination date) and basic demographic information (gender, age in months, residential community) of infants aged 6 to 35 months in target communities. Process monitoring data (short message platform push success rate, click rate, structured recommendation QR code scanning records by community doctors) were automatically generated and exported by the system. Data Management: (1) Data Storage: All electronic data are stored on the hospital's encrypted servers, accessible only to research team members via authorized accounts. Paper materials (such as questionnaire records and QR code registration forms) are kept in locked filing cabinets. (2) Data Confidentiality: All personal identifiers (name, ID number, home address, etc.) are removed from the data, and participants are identified only by research ID numbers. Participants' privacy is strictly protected during data export and processing. (3) Data Usage: The data shall only be used for the scientific purposes stated in this study and shall not be used for other commercial purposes or unauthorized secondary research. (4) Data Retention Period: After the completion of the study, the data will be retained for 5 years. Upon expiration, the data will be anonymized or destroyed in accordance with hospital regulations.
