Objective: To analyse the risk factors of drug-resistant bacterial pneumonia in elderly inpatients in Shandong Province.

Methods: From January 2014 to December 2016, 10 cities and counties were randomly selected in Shandong Province, three medical institutions were also selected in each city or county, 200 cases of elderly patients with bacterial pneumonia were recruited as research objects in each of the medical institutions based on the random principle. They were receiving sputum culture and smear examination, analysis of bacterial pathogens characteristics and drug resistance related risk factors.

Results: A total of 6000 subjects were studied. The result of sputum culture and susceptibility test showed that 11352 bacterial strains were isolated, among which Klebsiella pneumoniae, Pseudomonas aeruginosa, Escherichia coli and Bowman had the largest number and the most serious drug resistance.

Conclusion: Klebsiella pneumoniae, Pseudomonas aeruginosa, Escherichia coli and Acinetobacter baumannii are the main pathogens in elderly patients with bacterial pneumonia in Shandong Province, and the serious drug resistance also needs attention.
