Abstract:
Objective To determine the distribution and antibiotic resistance of hospital - associated pneu-monia(HAP) in senile patient,and the high risk factors of HAP,pathogenic bacterium and prognosis,so as to instruct the clinic prevention and treatment. Methods Patients with age over 60 years old,who were diagnosed of HAP with confirmed pathogens. Pathogens were identified, then the antibiotic resistance was determined by Kirty-Baucer disk dif-fusion assay. High risk factors of HAP, pathogenic bacterium and prognosis were analyzed by Logistic regression analy-sis. Results The first 10th pathogens of HAP patients were pseudomonas aeruginosa( 16.1% ),staphylococcus au-reus( 14.6% ) ,klebsiella pneumonia( 10.2% ), escherichia coil (8.8%) ,staphylococcus hemolyticus (7.3%). MR-SA accounted for 90% in staphylococcus aureus. The drug resistance of pseudomonas aeruginosa to imipenem was 29.5%. The high risk factors of HAP were acute brain accident, hypoalbuminemia, tracheal intubation or mechanical ventilation, rennal failure,COPD, gastric tube, anaemia,liver disfunction,long length of stay ( all P < 0.05 ). The mor-tality of senile HAP was 29.2%. Conclusion There are high antibiotic resistance and high mortality of HAP in se-nile patients. Measures should be taken to modify the risk factors.
