研究目的: |
1.1通过纵向随访观察,识别ICU老年机械通气患者获得性衰弱的发展轨迹亚组及早期活动剂量的变化轨迹模式,探索两种轨迹的动态关联效应及相互影响机制,为后续剂量-效应分析和预测模型构建奠定基础。 1.2分析不同获得性衰弱轨迹亚组和早期活动剂量轨迹对患者结局机械通气时间、撤机成功率、ICU住院时间、28天死亡率、出院后功能状态、生活质量、再入院率、死亡率的独立及联合影响效应,明确早期活动剂量对改善患者结局的作用及最佳剂量范围。 1.3整合患者基线特征、动态临床指标、获得性衰弱轨迹及早期活动剂量轨迹等多维度数据,运用长短期记忆神经网络(Long Short-Term Memory,LSTM)构建ICU老年机械通气患者获得性衰弱的动态风险预测模型,验证模型的预测性能,为获得性衰弱的早期识别和精准防控提供科学依据。 |

Objectives of Study: |
1.1 Through longitudinal follow-up observations, identify the development trajectory subgroups of acquired frailty in elderly ICU patients undergoing mechanical ventilation and the trajectory patterns of early activity dose changes, exploring the dynamic associative effects and interaction mechanisms between the two trajectories, thus laying the foundation for subsequent dose-effect analysis and predictive model construction. 1.2 Analyze the independent and combined effects of different acquired frailty trajectory subgroups and early activity dose trajectories on patient outcomes including mechanical ventilation duration, weaning success rate, ICU length of stay, 28-day mortality, post-discharge functional status, quality of life, readmission rate, and mortality, clarifying the role of early activity dose in improving patient outcomes and determining the optimal dose range. 1.3 Integrate multidimensional data including patient baseline characteristics, dynamic clinical indicators, acquired frailty trajectories, and early activity dose trajectories, and apply Long Short-Term Memory (LSTM) neural networks to construct a dynamic risk prediction model for acquired frailty in elderly ICU patients undergoing mechanical ventilation, validating the predictive performance of the model, and providing scientific basis for early identification and precise prevention and control of acquired frailty. |

纳入标准: |
1.年龄≥60周岁; 2.接受有创机械通气,且预计通气时间≥48小时; 3.住重症监护室≥3天; 4.患者家属均知情研究内容。 |
||||||||||||||||||||||
|
Inclusion criteria |
1. Age >= 60 years; 2. Received invasive mechanical ventilation, with an expected ventilation time >= 48 hours; 3. Stayed in the intensive care unit for >= 3 days; 4. Patients' family members are fully informed about the research content. |
||||||||||||||||||||||
|
排除标准: |
1.存在不稳定骨折、重型颅脑损伤、肺栓塞、深静脉栓塞、活动性出血等,需制动或限制活动的情况。 2.预计短期停止治疗:预计在纳入后24小时内可能停止机械通气、放弃治疗或转出ICU。 3.既往参与试验:过去90天内已参与过相关临床试验(避免重复纳入影响结果)。 4.体外膜氧合支持:正在接受体外膜氧合(ECMO)支持的患者通常被排除,因其治疗模式和病情复杂性不同。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Presence of unstable fractures, severe craniocerebral injury, pulmonary embolism, deep vein thrombosis, active bleeding, or other conditions requiring immobilization or activity restriction. 2. Expected short-term treatment cessation: Mechanical ventilation withdrawal, treatment abandonment, or ICU transfer anticipated within 24 hours after enrollment. 3. Previous trial participation: Participation in related clinical trials within the past 90 days (to avoid duplicate inclusion affecting results). 4. Extracorporeal membrane oxygenation support: Patients currently receiving extracorporeal membrane oxygenation (ECMO) support are generally excluded due to the differences in treatment modalities and the complexity of their conditions. |
