【摘要】：目的分析骨科创伤患者医院获得性肺炎(HAP)的危险因素,为制定预防控制措施提供依据。方法回顾性调查2011年6月—2015年5月某院骨科病房创伤患者发生HAP的情况,并采用单因素和多因素logistic回归分析其危险因素。结果共调查骨科创伤患者2 578例,发生HAP92例,HAP发病率3.57%。92例HAP患者共检出病原菌107株,主要为肺炎克雷伯菌(22株,占20.56%)、大肠埃希菌(14株,占13.08%)、鲍曼不动杆菌(13株,占12.15%)等。住院日数≥15 d、吸烟史≥3年、卧床≥7 d、伴有基础疾病、合并症、留置导尿管≥7 d、采用手术治疗、采用机械通气、入住ICU、开放性损伤、血糖≥11 mmol/L、血浆清蛋白30 g/L、血红蛋白浓度90 g/L和糖皮质激素使用≥4 d等14个因素均是骨科创伤患者发生HAP的危险因素(均P0.05)。多因素logistic回归分析显示,吸烟、卧床、手术治疗、机械通气、使用糖皮质激素和贫血6个因素为骨科创伤患者发生HAP的独立危险因素。结论骨科创伤患者HAP与多种因素有关,其中以手术治疗、机械通气、糖皮质激素使用、长期吸烟、卧床和贫血等6个因素为主。
[Abstract]:Objective to analyze the risk factors of (HAP) in orthopedic trauma patients with hospital-acquired pneumonia, and to provide evidence for prevention and control measures. Methods the incidence of HAP in trauma patients in orthopedic ward from June 2011 to May 2015 was investigated retrospectively. the risk factors were analyzed by univariate and multivariate logistic regression analysis. Results A total of 2578 patients with orthopaedic trauma occurred HAP. The incidence of HAP was 3.57%. A total of 107 strains of pathogenic bacteria were detected in 92 patients with HAP, mainly Klebsiella pneumoniae (22 strains, 20.56%), Escherichia coli (14 strains, 13.08%) and Acinetobacter baumannii (13 strains, 12.15%).
