目的了解住院老年患者下呼吸道念珠菌感染情况及相关危险因素,为有效控制呼吸道念珠菌感染提供依据。方法采用回顾性调查方法,对某医院老年病房住院老年患者下呼吸道念珠菌感染情况进行了调查与分析。结果从该医院老年病房482例下呼吸道感染的老年患者病原学标本中检出病原菌316株,其中检出念珠菌72株,构成比为22.8%。在检出的感染念珠菌中,白色念珠菌占68.8%。高龄、基础疾病、住院时间、侵入性操作和长期大量使用抗菌药物等构成老年患者下呼吸道念珠菌感染的重要危险因素。结论该医院老年病房住院患者下呼吸道念珠菌感染率较高,影响因素复杂,应有重点地加强防控对策。
Objective To investigate the prevalence of Candida infections in lower respiratory tract and related risk factors in elderly patients in hospital and provide evidence for effective control of Candida infections in respiratory tract. Methods A retrospective investigation was conducted to investigate the lower respiratory tract Candida infection in hospitalized elderly patients in a hospital ward. Results A total of 316 strains of pathogenic bacteria were detected in pathogenic specimens of 482 elderly patients with lower respiratory tract infection in the hospital’s elderly ward, of which 72 Candida were detected with a ratio of 22.8%. Candida in the detection of Candida albicans accounted for 68.8%. Elderly patients, underlying diseases, hospitalization time, invasive procedures and long-term extensive use of antimicrobial agents constitute an important risk factor for lower respiratory tract Candida infections in elderly patients. Conclusion The prevalence of candidiasis in the lower respiratory tract of hospitalized patients in the ward of the hospital is high, and the influencing factors are complex. Therefore, prevention and control measures should be emphasized.
