研究目的: |
描述ICU 成年患者中谵妄的临床表型分布特征,并识别ICU 患者脑功能状态(正常、谵妄、昏迷)随时间变化的动态轨迹,分析不同谵妄临床表型和波动轨迹与临床结局之间的关联。 |

|
Objectives of Study: |
To describe the distribution of clinical delirium phenotypes among adult ICU patients, to identify dynamic trajectories of brain function states (normal, delirium, coma) over time in ICU patients, and to examine the associations between different delirium phenotypes and fluctuation trajectories and clinical outcomes. |

|
排除标准: |
1. 入院前存在严重认知障碍(如重度痴呆); 2. 存在严重的原发性神经系统疾病(如严重创伤性脑损伤、大面积脑梗死或脑出血); 3. 在ICU 期间持续处于昏迷状态(Richmond 躁动-镇静评分[RASS] 持续为-4或-5 分),无法进行谵妄评估; 4. ICU 住院期间缺乏谵妄评估记录; 5. 关键变量(如APACHE II 评分、每日SOFA 评分、每日RASS 和CAM-ICU 评估)的数据缺失率超过20%。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Pre-existing severe cognitive impairment prior to admission (e.g., severe dementia); 2. Severe primary neurological disorders (e.g., severe traumatic brain injury, massive cerebral infarction, or intracerebral hemorrhage); 3. Persistent coma throughout the ICU stay (Richmond Agitation–Sedation Scale [RASS] consistently −4 or −5), precluding delirium assessment; 4. Absence of delirium assessment records during the ICU stay; 5. Missing data rate >20% for key variables (e.g., APACHE II score, daily SOFA score, and daily RASS and CAM-ICU assessments). |

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: |
研究所有信息均通过临床大数据平台导出后,由完全独立的第三方专业加密人员进行脱敏(去标识化)及加密处理,该第三方人员仅负责数据加密并设置访问密码,不参与后续任何研究流程,且与本研究团队无任何隶属或合作关系,确保其不会接触或利用研究数据。脱敏加密后的数据中不包含可识别受试者身份的姓名、手机号、身份证号、登记号等信息,根据所获得的信息无法联系到受试者,因此申请免除知情同意。本研究为纯科学研究,旨在探索ICU谵妄的临床表型特征,无任何商业转化计划或商业利益关联。若未来基于本研究模型开发的应用涉及商业转化,将重新提交伦理审查申请并严格遵守知情同意要求。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
All study information will be exported from the clinical big data platform and then de-identified (anonymized) and encrypted by a completely independent third-party professional data security specialist. This third-party specialist is responsible only for data encryption and access password setting, does not participate in any subsequent research procedures, and has no affiliation or collaborative relationship with the research team, thereby ensuring that they will not access or use the research data. The de-identified and encrypted dataset does not contain personally identifiable information such as participants’ names, mobile phone numbers, national identification numbers, or registration numbers. Based on the information obtained, participants cannot be contacted; therefore, a waiver of informed consent is requested. This study is purely for scientific research purposes and aims to explore the clinical phenotypic characteristics of ICU delirium, with no plan for commercial translation and no commercial interests involved. If any future application developed from the study model involves commercial translation, a new ethics review application will be submitted, and informed consent requirements will be strictly followed. |
