摘要
目的了解医院老年病科老年患者医院感染发病情况及其危险因素,探讨如何有效预防和控制老年患者医院感染。方法采用回顾性调查方法,对某医院老年病科1826例年龄>60岁的老年患者医院感染病例资料进行统计分析。结果老年病科60岁以上的老年患者医院感染发病率为14.46%。在270例次医院感染患者中有224例次为呼吸道感染,占82.96%;泌尿系感染27例次,占10.00%。住院时间由10d以内增加到30d,医院感染发生率由1.89%增加到14.39%;住院时间>60d者,医院感染发生率占46.21%。医院感染患者送检的微生物标本中检出阳性率41.24%,其中真菌占22.5%,肺炎克雷伯菌占17.5%。结论老年患者医院感染发生率比较高,感染部位呼吸道感染为主,感染病原菌以真菌为主;患者年龄越大,住院时间越长,医院感染发生率越高。
Objective To investigate the situation and risk factors for nosocomial infection in old patients hospitalized in geriatric department, and to explore the effective prevention and control of nosocomial infection in old patients. Methods A retrospective investigation on 1826 medical records of the patients aged above 60 years hospitalized in our hospital geriatric department was carried out. Results The incidence rate of nosocomial infections in patients aged above 60 years was 14. 46%. Of 270 cases, 224 were infections of respiratory tract （ 82.96% ）, 27 were infections of urinary tract （ 10.00% ）. As the hospitalization time lengthened from 10 days to 30 days, the incidence rate increased from 1.89% to 14.39%. The incidence rate was 46.21% when the hospitalization duration exceeded 60 days. The positive detection rate of microbiological specimens taken from patients with nosocomial infections was 41.24% , with fungi and Klebsiella pneumoniae as the most common pathogens （22.5% and 17.5% respectively）. Conclusions The incidence rate of nosocomial infections was high in elderly patients. The main infection site was respiratory tract and the main pathogen was fungi. The risk factors related with the nosocomial infections included the patient＇s age and the duration of hospitalization.
