TIME POINT PREVALENCE RATE SURVEY OF HOSPITAL INFECTIONS ON 489 PATIENTS WITH INFECTIOUS DISEASES

To evaluate the charasteristics and risk factors of hospital infections in patients with contagious diseases, 489 patients with contagious diseases were analyzed. Among 18 patients who contracted hospital infections, 17 were suffering from chronic hepatitis. 77 78% of them were over 40 years old. Infection of ascitic fluid, lower respiratory tract, and blood stream comprised 77 78% of the infections. Most of the doctors used antibiotics empirically. The survey showed that patients over 40 years old in an infectious diseases hospital were vulnerable to hospital infections. Hospital infection often occurred in the abdomen, lower respiratory tract, and blood stream. Abdominal paracentesis liver puncture biopsy, and lumbar puncture were the first three exogenous risk factors.
