目的 构建首发脑出血患者并发卒中相关性肺炎的风险预测模型并验证模型的预测性能。方法 回顾性分析2012年1月—2022年12月广州市第一人民医院治的419例首发脑出血患者的临床资料，按照7︰3比例随机化分为训练列（293例）和验证队列（126例）。统计基于开发队列数据，采用Logistic回归模型分析首发脑出血患者并发卒中相关性肺炎的影响因素，并构建风险预测模型。基于开发队列和验证队列数据，采用校准曲线、受试者操作特征（ROC）曲线下面积和决策曲线分析模型的预测性能。结果 419例首发脑出血患者中有113例发生卒中相关性肺炎，发生率为26.97%。美国国立卫生研究院卒中量表（NIHSS）评分、吞咽困难、初始血肿体积、中性粒细胞百分比与白蛋白比值（NPAR）、中性粒细胞计数与淋巴细胞计数比值（NLR）、手术治疗、气管插管、留置胃管均是首发脑出血患者并发卒中相关性肺炎的影响因素（P＜0.05）。基于上述影响因素构建了首发脑出血患者并发卒中相关性肺炎的风险预警模型，校准曲线显示模型在开发队列和验证队列中预测卒中相关性肺炎发生率均与实际发生率相近；ROC曲线显示此模型在开发队列、验证队列中预测的曲线下面积分别为0.906（95%CI：0.867~0.937）、0.884（95%CI：0.815~0.934）；决策曲线分析显示当开发队列阈概率在3%~80%内、验证队列阈概率在2%~76%内使用此模型干预比全/无干预更有临床价值。结论 基于NIHSS评分、吞咽困难、初始血肿体积、NPAR、NLR、手术治疗、气管插管、留置胃管构建的首发脑出血患者并发卒中相关性肺炎的风险预测模型具有良好预测性能和临床应用价值。

      Objective To construct a risk prediction model for stroke associated pneumonia in patients with initial cerebral hemorrhage（ICH）and validate the predictive performance of the model．Methods A retrospective analysis was conducted on the clinical data of 419 patients with ICH admitted to our hospital from January 2012 to December 2022．They were randomly divided into a development cohort（293 cases）and a validation cohort（126 cases）according to a 7∶3 ratio．The Logistic regression model was used to analyze the influencing factors of stroke related pneumonia in patients with ICH based on the development cohort data，and a risk prediction model was constructed．Based on the development cohort data and validation cohort data，the predictive performance of the model was analyzed using calibration curves，receiver operating characteristic（ROC）curve，and decision curve analysis．Results Among 419 patients，113 developed stroke associated pneumonia，with a rate of 26.97%．The National Institutes of Health Stroke Scale（NIHSS）score，swallowing difficulties，initial hematoma volume，neutrophil percentage to albumin ratio（NPAR），neutrophil count to lymphocyte count ratio（NLR），surgical treatment，endotracheal intubation，and indwelling gastric tube were all independent influencing factors for stroke associated pneumonia in patients with ICH（P＜0.05）．Based on the above influencing factors，a risk prediction model for stroke associated pneumonia in patients with ICH was constructed．The calibration curve showed that the predicted incidence of stroke associated pneumonia by the model in both the development and validation cohorts was close to the actual incidence．The ROC curve showed that the predicted area under the curve for this model in the development cohort and validation cohort was 0.906（95%CI：0.867-0.937）and 0.884（95%CI：0.815-0.934），respectively．The decision curve analysis showed that when the threshold probability of the development cohort was between 3%-80%，and the threshold probability of the validation cohort was between 2%-76%，the intervention using this model was more clinically valuable than all/no intervention．

Conclusions The risk prediction model for stroke associated pneumonia in patients with ICH based on NIHSS score，swallowing difficulties，initial hematoma volume，NPAR，NLR，surgical treatment，tracheal intubation，and indwelling gastric tube has good predictive performance and clinical application value．

目的 调查非重症监护室护士对住院卧床老年患者肺康复的知信行现状,探讨其影响因素。方法 采用自行设计的卧床老年患者肺康复知信行现状调查问卷,对广州市第一人民医院的555 名非重症监护室护理人员进行调查。结果 共回收有效问卷513份。调查对象肺康复知信行总分为（76.01±12.27）分,知识维度、态度维度、行为维度得分分别为（14.09±3.25）、（21.89±3.38）、（40.03±9.87）分。多元回归分析显示,主要影响护士对住院老年卧床患者实施肺康复知信行的因素为护龄、是否参加过肺康复相关培训及科室是否已开展肺康复（P<0.05）。结论 非重症监护室护士对卧床老年患者肺康复的态度积极,行为良好,但知识有待提升。建议开展卧床老年人相关肺康复培训,激励护士主动学习肺康复新理念的积极性和主动性,强化理论联系临床实践,从而提高临床护理质量。

Objective To investigate the knowledge,attitude and practice of non-intensive care unit（ICU）nurses about pulmonary rehabilitation of hospitalized bedridden elderly patients,and to explore the influencing factors．Methods A self-designed questionnaire on the status of knowledge,attitude and practice about pulmonary rehabilitation of bedridden elderly patients was used to investigate 555 non-ICU nurses in our hospital．Results A total of 513 valid questionnaires were collected．The total score of pulmonary rehabilitation was（76.01±12.27）,and the scores of knowledge,attitude and practice were（14.09±3.25）,（21.89±3.38）and（40.03±9.87）,respectively．Multiple regression analysis showed that the main factors affecting nurses' knowledge,attitude and practice in implementing pulmonary rehabilitation for hospitalized elderly bedridden patients were nursing age,whether they had participated in training related to pulmonary rehabilitation and whether pulmonary rehabilitation had been carried out in the unit（P<0.05）．Conclusions Non-ICU nurses have positive attitudes and good practice toward pulmonary rehabilitation for bedridden elderly patients,but their knowledge needs to be improved．It is recommended that training on pulmonary rehabilitation for the bedridden elderly be carried out to motivate nurses to learn new concepts of pulmonary rehabilitation,strengthen the link between theory and clinical practice,and improve the quality of clinical care．
