Results:Of all 513 cases, the nosocomial infections occurred in 54 cases with an infection rate of 10. 5%. The respiratory system was the predominant infection site, accounting for 81. 5%. The incidence of nosocomial infections was high in the patients of more than 75 years old, with more than 5 years of course of disease, or with concomitant physical illness (P<0. 05). Conclusions: The respiratory is the most common infection sites for the elderly patients with mental disorders. The major objects in prevention are the patients with advanced age, long duration and concomi-tant physical illness.
