Abstract:
Objective To investigate infection pathogens and drug resistance of patients in the department of geriatrics ,so as to guide the rational use of antibacterial agents .Methods Retrospectively analysed data on clinical specimens of 1 563 cases of elderly patients from 2014 to 2013 .Results A total of 591 non‐repeated strains was isolated and the positive rate was 37 .8% .Strains mostly were isolated from sputum specimens (299 strains ,accounted for 50 .6% ) ,followed by urine specimens(171 strains ,accoun‐ted for 28 .9% ) ,secretion specimens(75 strains ,accounted for 12 .7% ) and blood specimens(15 strains ,accounted for 2 .5% ) .The isolated pathogenic bacteria mainly were gram‐negative bacteria(72 .60% ) ,which mostly were Pseudomonas aeruginosa .Acineto‐bacter baumannii ,Escherichia coli and Staphylococcus aureus has relatively high resistance rates against most of antibacterial agent . A total of 54 strains of multi‐drug resistant bacteria were isolated ,which was accounted for 56 .3% .Conclusion The pathogenic bacteria in the elderly patients mainly are gram‐negative bacteria ,pathogens have high resistance rates to antimicrobial agents ,and the multi‐drug resistance is serious ,so it is necessary to use antibacterial agents rationally based on the results of drug susceptibility tests .
