【Abstract】 OBJECTIVE To investigate the characteristics and preventive measures of nosocomial infection in aged patients. METHODS Retrospective survey was carried out in 64 aged patients for the situation of nosocomial infection. RESULTS Total nosocomial infection rate was 7.11%, and the mortality was 9.375%, significantly higher than that of uninfected cases (χ 2=7.44, P<0.01). The infection rate increased in winter and in spring (66.6%). The respiratory tract was found to be the most commonly involved sites (54.6%). Nosocomial infection is related to long period hospitalization, long duration of combined antibiotics and steroids, dysfunction of immunity and aggressive procedures. The most common bacteria were Gram negative bacilli (64%). CONCLUSIONS To control using antibiotics, reduce hospitalization time, enhance immunity, lessen aggressive procedures and other induced factors in order to reduce nosocomial infections.更多还原
