Profile of bacterial incidence and antimicrobian resistence in a hospital

Abstract

Indiscriminate use of antimicrobian drugs has caught the attention of people because of their role in the development of multi-resistant microorganisms. This study intends to draw a bacteriological profile of infections in hospitalized patients, and the resistance and sensitivity to the antimicrobian drugs, raising the most common microorganisms per internment department and site where samples were collected. It is a descriptive study, cross-section, retrospective, document analysis of the 402 positive results of cultures during the period of one year in a hospital. The statistical treatment used was Pearson's X² test and Student-Newman-Keuls "t"test (p < 0,05). After the data was analyzed, it was observed that E. coli is the main cause of UTE infection; S. aureus of infections of the cornea and circulation system; and S. epidermidis of catheter infections. P. aeruginosa appeared in 19.5% of positive results, sensitive to imipenem in 77.2% of cases and resistant to amikacin, the main cause of infections in male medical clinic and ICU, at 61%. Therefore it is necessary that health workers should be aware of the rational and adequate use of antimicrobian drugs, minimizing the risk of individuals developing resistance to them.
