研究目的:

本研究旨在通过随机对照试验,评价术前数字化认知训练方案在拟行非体外循环冠状动脉旁路移植术(Off-pump Coronary Artery Bypass Grafting, OPCABG)患者中的应用价值,重点观察其对术后认知功能障碍(Postoperative Cognitive Dysfunction, POCD)发生率的影响,为围术期神经认知保护策略提供循证医学证据。  

Objectives of Study:

This study is designed as a randomised controlled trial to assess the efficacy of a preoperative digital cognitive training programme in patients undergoing off-pump coronary artery bypass grafting (OPCABG). The primary focus is to evaluate its effect on the incidence of postoperative cognitive dysfunction (POCD), thereby providing high-quality evidence to inform perioperative neurocognitive protection strategies.

组别:

认知数字疗法组

样本量:

67

Group:

Digital Cognitive Therapy Group

Sample size:

干预措施:

除了接受常规术前准备外,试验组患者将从入院第1天开始接受每天1次,每次60分钟的认知数字化训练。认知训练师在入院第1天对患者进行设备使用方法的宣教,并告知患者尽量选择一天中的某一固定空闲时间进行训练,中间可以暂停休息,当日必须完成。手术前认知训练总时长至少为5个小时。认知训练师应关注后台信息,如果患者当天没有完成有效训练,由认知训练师通过打电话方式提醒患者完成训练。

干预措施代码:

Intervention:

In addition to standard preoperative preparation, patients in the intervention group will undergo daily digital cognitive training sessions lasting 60 minutes each, starting from the first day of admission. On the first day, a cognitive trainer will instruct patients on how to use the training device and advise them to perform the sessions at a consistent, convenient time each day. Breaks are allowed during the session, but each day’s training must be completed. The total preoperative training duration must be at least 5 hours. The cognitive trainer will monitor the backend data, and if a patient fails to complete an effective session on a given day, the trainer will remind the patient by phone to complete the training.

随机方法(请说明由何人用什么方法产生随机序列):

随机序列由独立的临床研究协调员(CRC)利用电子数据采集系统(EDC)内置的随机化模块生成。采用计算机生成的随机数字表法进行随机分组,按照预设的1:1比例将受试者分配至干预组和对照组。随机序列由系统自动生成并保存,研究者在受试者完成入组并确认符合纳入标准后,通过EDC系统获取随机分组结果。随机序列对研究实施人员保持隐藏。

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

An independent Clinical Research Coordinator (CRC) will generate the randomisation sequence using the randomisation module embedded in the Electronic Data Capture (EDC) system. Participants will be allocated to the intervention group or the control group at a 1:1 ratio according to a computer-generated random sequence. The allocation sequence will be automatically generated and maintained within the EDC system. Investigators will access the allocation assignment only after participant enrolment and confirmation of eligibility. Allocation concealment will be ensured throughout the randomisation process.

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:

本研究为开放标签随机对照试验。由于干预措施的性质,受试者及研究实施人员无法实施盲法。为降低测量偏倚,主要结局指标的评估由独立的结局评价人员完成,评价人员不参与随机分组及干预实施,并对受试者分组信息保持盲态。

Blinding:

This study is designed as an open-label randomized controlled trial. Due to the nature of the intervention, blinding of participants and study personnel is not feasible. To minimize assessment bias, the primary outcome measures will be evaluated by independent outcome assessors who are not involved in the randomization process or intervention delivery and will remain blinded to group allocation throughout the study.

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:

本研究采用CRF与EDC系统相结合的数据管理模式。研究数据首先记录于CRF,由经过培训的CRC录入EDC系统。系统设置逻辑核查、范围核查及缺失值检查等功能,对异常数据进行自动提示和追踪。研究数据采用编码化管理,受试者身份信息与研究数据分开保存。所有数据均存储于具有权限管理和审计追踪功能的EDC系统中。研究结束后完成数据核查和锁库,确保数据的真实性、完整性和安全性。

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

Data will be collected using Case Report Forms (CRFs) and managed through an Electronic Data Capture (EDC) system. Trained Clinical Research Coordinators (CRCs) will enter CRF data into the EDC system. Automated validation procedures, including logic, range, and missing-data checks, will be applied to ensure data quality. Participant information will be coded, and identifiable personal information will be stored separately from study data. The EDC system will provide secure storage, access control, and audit trail functions. Data verification and database locking will be conducted at the end of the study to ensure data integrity, completeness, and confidentiality.
