Abstract:
OBJECTIVE To analyze the pattern of antibiotic usage and antibiotic resistance tendency in our hospital.METHODS The use of antibiotics was evaluated by calculating DDDs;the bacteria were isolated and identified,and the susceptibility was tested by using microdilution method.Ten species of the most common bacteria,such as Staphylocccus aureus,and their antibiotic resistance tendency in two years were evaluated.RESULTS The average antibiotics days were 11.6 in two years.Ten species with 8967 strains were isolated in which 57.70% bacteria were Gram-negative.The rate of extended spectrum ?-lactamases(ESBLs) of Enterobacteriacae was 31.18%.42.3% Bacteria were Gram-positive,the isolation rate of MRSA was up to 76% and 56.8%,respectively.CONCLUSIONS The total cost of antibiotics remains at a high level.The ESBLs is still the major problem in gram negative germ.Vancomycin-resistant Enterococcus has been discovered.It is urgent to conduct epidemiological investigation and to take appropriate measures to control bacterial resistance and antibiotics usage.
