RESUMO
OBJECTIVE:To study the correlation between the rate of inpatients using antibacterials and the cross-sectional rate of inpatients using antibacterials.METHODS:A cross sectional study was conducted on the use of antibacterials in 1040 inpatients between May 22 and May 23 in 2007.Besides,the discharge case histories of 100 cases were collected randomly for an analysis.RESULTS:Of the total 1 040 inpatients,510(49.04%)used antimicrobials.The rate of inpatients using antibacterials in comprehensive ICU took the lead at 100%,followed by pediatric department(86.05%)and the department of nephrology(84.62 %).The average rate of inpatients using antibacterials in surgery department was significantly higher than in the department of internal medicine(63.52% vs.33.94%).81% of the discharged cases used antibacterials.The irrational use of antibacterials manifested as improper timing of medication,prolonged use of antibacterials for prophylactic purpose etc.CONCLUSION:The proportion of the patients using antibacterials in descending order were inpatients,cross-sectional inpatients and outpatients.It is necessary to tighten control on the rational use of antimicrobials.
