摘要
目的了解某医院1996—2000年医院获得性肺炎(HAP)的发病情况及其危险因素变化趋势。方法建立医院感染监测网,监测住院患者的HAP发病率和病死率及其危险因素。结果共监测住院患者55 214例,发生医院感染1 758例(平均3.18%),其中HAP患者893例(1.62%),占医院感染患者的50.80%。5年间HAP平均年发病率为166/万,其中男性占131/万,明显高于女性35/万(u=4.58,P<0.01);每年平均病死率15.90%,其中男性113例(12.65%),女性29例(3.25%),两者比较,差异有显著性(u=8.79,P<0.01)。基础疾病、住院天数、住重症监护室天数、手术及其他介入性操作等危险因素皆逐年升高(均P<0.05)。结论HAP居此次调查中医院感染的首位,男性患者发病率和病死率均高于女性;引起HAP的危险因素多呈上升趋势,应进行针对性监控。
Objective To investigate the occurrence of hospital-acquired pneumonia （HAP） and analyse on related risk factors in a hospital during the years of 1996-2000. Methods Nosocomial infection（NI） surveillance network was established to monitor the morbidity, mortality and risk factors of HAP patients. Results A total of 55 214 inpatients were monitored, 1 758 （3. 18%） NI occurred, 893 patients developed HAP, which accounting for 50. 80% of NI patients. The average annual incidence during five years was 166/10 000, male patients accounting for 131/ 10 000, which was obviously higher than that of female patients of 35/10 000 （u = 4. 58, P〈0. 01） ; the average annual mortality was 15.90%, male patients were 113 cases （12. 65%）, female patients were 29 cases （3. 25%）, there was significant difference between the two （u=8. 79, P〈0. 01）. The risk factors, such as primary diseases, hospitalization days, operation and the other invasive manipulations increased year by year （all P〈0. 05）. Conclusion HAP was the main NI in the investigation, the morbidity and mortality of male patients were both higher than that of female patients; the risk factors for HAP had a tendency of increase year by year, monitor should carried out accordingly.
