干预措施:

在本研究中,干预组患者将接受基于虚拟现实(VR)技术的术前ICU环境预适应干预,该干预通过PICO-VR头戴设备播放一段时长不足5分钟的高清360度全景视频实施。该视频旨在帮助患者熟悉ICU的典型环境、声音、工作人员角色和护理流程,从而做好心理准备。视频模拟真实的多床位ICU环境,呈现患者可能遇到的各种临床场景,包括心电监护仪的报警声、机械通气设备等医疗设备的展示,ICU医生进行日常查房并解释临床决策(如实验室检查结果和治疗方案)的过程,以及护士提供24小时床旁监护和护理的场景。此外,视频还展示了辅助人员帮助患者进行影像学检查时的体位调整、个人卫生护理和活动协助等操作,以及预防压疮的定时翻身、口腔护理、雾化治疗和吸痰等常规护理流程。对于气管插管的患者,视频还演示了如何通过视觉交流辅助工具(如图片板)进行沟通,包括表达"你疼吗?"或"你想喝水吗?"等常见需求。 术后,将启用一个名为智能化谵妄护理系统(AI-AntiDelirium)的平台,该平台依据PADIS 指南和系统设计原则构建。AI-AntiDelirium 平台由四个核心模块组成:谵妄评估、谵妄风险因素评估、个性化护理计划制定和护理活动清单管理。谵妄的筛查工作将采用由本研究团队研发的智能混乱评估方法(Intelligent Confusion Assessment Method for theIntensive Care Unit, iCAM-ICU)进行。CAM-ICU 是一种在国际上广泛认可并被认为是筛查ICU 谵妄的金标准的工具, 我们团队做的CAM-ICU 该工具中的注意力筛查检查(ASE)具有很高的可靠性,kappa 系数为 0.83(P<0.1),评分者之间的可靠性也很高,kappa 系数为 0.92(P<0.001)。CAM-ICU 还显示出高灵敏度(91.8%和 93.4%)和特异性(90.8%和 87.7%)。iCAM-ICU 是为 ICU 谵妄筛查设计的智能化评估系统,该工具在护士研究者中展现出了 0.96 的高Kappa一致性系数,证明了其卓越的信度。与诊断的金标准相比,iCAM-ICU 在护士研究者中的敏感性为 95.2%和 93.7%,特异性为 93.3%和 93.2%,显示出良好的效度。在临床护士中,该工具的敏感性和特异性分别为 86.7%和 97.7%。干预将主要由床边护士实施,他们将在干预开始前 2 周接受 AI-Antidelirium 的培训。工作人员将在其个人数字助理(PDA)上安装 AIAntiDelirium平台,并接受多模式教育,以熟悉所有程序。对于 ICU 谵妄评估,床边护士将使用 AIAntiDelirium 的 iCAMICU 模块每天至少两次评估 ICU 谵妄,一次在上午 8 点至 10 点之间,一次是在下午 4 点至 6 点之间。评估完成后,系统将自动指示患者是否患有谵妄。风险因素评估模块将依据预测模型来评估谵妄发生的可能性。对于风险因素评估,床边护士将应用风险因素评估模块来评估患者是否存在以下 10 个谵妄相关风险因素中的一个或多个:(1)听力障碍,(2)视力缺陷,(3)疼痛,(4)使用镇静剂或镇痛药,(5)使用机械通气,(6)使用留置导管,(7)感染,(8)不动,(9)睡眠障碍,以及(10)缺乏家庭陪伴。个性化护理计划制定模块旨在为每位患者提供定制化的 ICU 谵妄护理方案,而护理活动清单管理模块则便于医护人员规划和执行针对性的护理活动。通过这些综合措施,本研究旨在为 ICU 患者的谵妄预防和管理提供科学、系统的辅助工具。护理计划模块将根据现有的风险因素自动生成个性化的 ICU 谵妄措施。ICU 护士将审查每位患者的所有干预措施,以确定护理计划是否可行。护理活动清单模块将根据个性化护理计划自动提供每次干预的时间表及其持续时间、强度或剂量以及提供者。护士将在整个轮班期间实施个人干预。护士在完成干预后点击 PDA 上的干预按钮后,智能化谵妄护理系统会自动记录他们的姓名和完成时间。

Intervention:

Participants in the intervention group will undergo a preoperative ICU orientation intervention using virtual reality (VR) technology. This intervention is delivered through a PICO-VR headset and consists of a high-quality, 360-degree panoramic video lasting less than five minutes. The purpose of this video is to help patients become psychologically prepared for the ICU environment by familiarizing them with typical sights, sounds, staff roles, and care procedures. The video simulates a realistic, multi-bed ICU environment and presents various clinical scenarios that patients are likely to encounter. These include exposure to medical devices such as ECG monitors with their beeping alarms, mechanical ventilators, and monitors with flashing indicator lights. It introduces patients to ICU physicians who perform daily ward rounds and explain clinical decisions, such as laboratory test reviews and treatment plans. Nurses are also shown providing 24-hour bedside monitoring and care. In addition, the video features support staff responsible for assisting patients with various procedures, such as repositioning for imaging (e.g., CT scans), helping with hygiene tasks, and assisting in mobility. Nursing care procedures such as regular turning to prevent pressure ulcers, oral care, nebulization therapy, and suctioning are demonstrated. Patients are also shown how they will be able to communicate while intubated using visual communication aids (e.g., picture boards) with common phrases such as "Are you in pain?" or "Do you want water?" Patients are informed that oral intake will be restricted for the first six hours after surgery, after which they may gradually resume fluid intake under supervision. The VR experience also highlights that staff will assist with feeding if needed. Early mobilization is encouraged, and patients are shown simple exercises, such as moving their arms and legs while in bed. Finally, the VR simulation explains the discharge process from the ICU to the general ward, showing how patients will be accompanied by nurses and support staff who transport their belongings and provide a structured handover to the ward nursing team. Postoperatively, all patients in the intervention group will receive care supported by the Artificial Intelligence Assisted Prevention and Management for Delirium (AI-AntiDelirium) platform. This system, based on the PADIS guidelines, includes four functional modules: (1) delirium assessment using the Intelligent Confusion Assessment Method for the ICU (iCAM-ICU); (2) risk factor evaluation; (3) personalized care plan generation; and (4) care activity checklist management. Bedside nurses, trained in the use of the AI platform, will perform ICU delirium assessments at least twice daily (once between 8:00–10:00 AM and once between 6:00–8:00 PM). The system will automatically identify patients at risk and suggest individualized care interventions accordingly. The platform assesses key delirium-related risk factors such as hearing or visual impairment, pain, sedative or analgesic use, mechanical ventilation, indwelling catheters, infections, immobility, sleep disturbances, and absence of family companionship. Based on these, a personalized care plan will be generated and reviewed by the nurses for feasibility. Scheduled interventions, including timing, duration, intensity, and responsible personnel, are displayed via the care activity checklist module. Nurses implement the interventions and record completion using their personal digital assistants (PDAs), allowing for automatic tracking and documentation.

Intervention:

Participants in the control group will receive standard preoperative care, which primarily involves verbal explanations about the surgical procedure and responses to any questions or concerns raised by the patient. No virtual reality or visual orientation will be provided prior to ICU admission. Following surgery, upon transfer to the intensive care unit (ICU), participants in the control group will receive postoperative care consistent with that of the intervention group. Specifically, the Artificial Intelligence Assisted Prevention and Management for Delirium (AI-AntiDelirium) platform will be utilized to guide delirium screening, risk assessment, and the implementation of personalized nursing interventions.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用置换区组随机化方法,设置4、6、8、10的变长区组,以确保干预组(接受虚拟现实ICU环境模拟联合AI-AntiDelirium护理)与对照组(仅接受AI-AntiDelirium护理)按1:1比例均衡分配。每个区组内两组人数相等(如区组大小为4时2:2分配,区组大小为6时3:3分配),并通过随机排列分配顺序降低可预测性和选择偏倚。随机序列由独立第三方使用R统计软件(4.5版)的blockrand程序包生成,该人员不参与受试者招募、干预实施或结局评估。根据该序列,研究团队将预先制备密封、不透光、按序编号的信封。每个信封仅标注与入组顺序对应的受试者编号(如患者001、002等)。

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

The randomization sequence will be generated using R statistical software (version 4.5) with the blockrand package by an independent third party who will not be involved in participant recruitment, intervention delivery, or outcome assessment. Based on this sequence, a set of sealed, opaque, and sequentially numbered envelopes will be prepared in advance. Each envelope will be labeled only with a participant identification number corresponding to the order of enrollment (e.g., Patient 001, 002, etc.).

公开/Public

盲法:

虽然无法实现完全盲法,但通过严格执行标准化操作流程、统一应用评估工具、以及仅采用经过验证的量表,可最大限度减少潜在偏倚。由单一经培训的研究者同时承担干预与评估任务虽有助于保持内部一致性、降低评估者间变异,但可能引入主观偏倚,该局限性将在研究中予以明确说明。

Blinding:

Due to the nature of the intervention, blinding of both the participant and the investigator is not feasible. The same researcher (the principal investigator) will deliver the intervention and conduct all outcome assessments using validated tools, including the iCAM-ICU, MMSE, Barthel Index (BI), and Sedation-Agitation Scale (SAS). Participants will be instructed not to discuss their group assignment during assessments to help reduce observer bias. Although full blinding is not possible, potential bias will be minimized through strict adherence to standardized protocols, consistent application of outcome measures, and the exclusive use of validated tools. The involvement of a single trained researcher in both intervention and assessment tasks may enhance internal consistency by reducing inter-rater variability; however, this approach also introduces the risk of subjective bias, which will be transparently acknowledged as a limitation in the study.
