To investigate the incidence of hospital-acquired pneumonia (HAP) and bacteriological characteristics in the emergency observation area, and to provide the basis for the prevention and control of HAP in emergency observation area.
Clinical data of HAP patients in the emergency observation area, department of respiratory medicine, surgical intensive care unit(SICU), and the medical intensive care unit (MICU)in the First Affiliated Hospital of Sun Yat-sen University during January 1st – December 30th, 2015 year were collected, especially bacteriological reports of blood culture and sputum culture. All clinical data were collected and analyzed by three attending physicians according to the diagnostic criteria of HAP.
The incidence of HAP was significantly higher than that in the department of respiratory medicine, SICU and MICU (P<0.05). The positive rate of bacterial culture in emergency observation area was only 6.2%, significantly lower than other departments. The top five bacteria of nosocomial infection in the emergency observation yard were Bauman Acinetobacter (41.57%), Escherichia coli (20.22%), Staphylococcus aureus (13.48%), Klebsiella pneumoniae (8.99%) and Pseudomonas aeruginosa (3.37%), and the resistant bacteria was at a relatively high level.
The incidence of HAP in emergency observation area was high, however, the positive rate of bacterial culture of sputum specimens was lower, and the positive proportion of ESBL and MRSA was high. The prevention and control of HAP in the emergency observation area should be strengthened.
