Objectives To study the epidemiological characteristics of 6307 cases of rheumatism patient's hospitalized infection in rheumatology in 2006-2011, study the prevalence of infection and the characteristics of rheumatology patients, and to analyze the influencing factors.

Methods Retrospective analysis the data of 6307 cases of patients in rheumatology in 2006-2011 who admitted to our hospital, analysis of various types of epidemiological characteristics in 1137 cases of infection, analysis of the incidence differences in different years and months and seasons, and analysis of the infection incidence difference of risk factors, and analysis of infection site differences.

Results Over the analysis of the incidence of infection in different years, the incidence of infection in 2010 was the most (40.89%). The high incidence of infection of the month was 4,5,6, concentrated in spring and summer (21.44% incidence, 20.16%). Infection group's age (43.11±18.86) and length of stay (12.82±10.88) were higher than non-infected group (40.37±18.52, 9.99±12.39), and the percentage of women infected group (68.69%) was more than non-infected group (64.18%), the odds ratio (OR) was 1.225. Study the site of infection, lung and kidney infection rate was the highest (26.47%, 17.68%). Tuberculosis infection in patients with younger, male-dominated and most happen in lung, and fungal infections in patients with age generally higher, mostly women and mostly associated with multiple infections and happen in mouth.

Conclusions The risk factors for infection in rheumatology are spring and summer, older age, long hospital stay, women, etc., should pay attention to the associated protective measures to reduce the incidence of infection.
