Sites and Pathogens of Nosocomial Infection:An Analysis of 2134 Cases

OBJECTIVE To understand the sites of nosocomial infection and its pathogenic bacteria. METHODS Infection sites and pathogens of 2134 patients with nosocomial infection were analyzed. RESULTS Totally 2235 infections were occurred. The main site was lower respiratory tract(30.47%),followed by upper respiratory tract(18.20%) and operated wound(12.17%). Among 815 strains,149 were Gram-positive bacteria,456 Gram-negative bacteria and 210 fungi. The rates of main Gram-positive cocci in lower respiratory tract,burned and operated wounds were 42.14%,20.00% and 12.86%,respectively; the rates of main Gram-negative rods in lower respiratory tract,burned wound and urinary tract was 44.14%,29.70% and 10.90%,respectively; the rates of fungi in lower respiratory tract,oral cavity and gastrointestinal tract was 41.90%,18.56% and 18.10%,respectively. CONCLUSIONS According to the main sites and pathogenic bacteria of nosocomial infection,countermeasure should be taken to prevent and control nosocomial infection.
