Infecções urinarias de origem comunitária diagnosticadas no Hospital Universitário Ana Bezerra (HUAB) entre os anos de 2015 a 2017.

Abstract

Community infection is indicated as that identified or incubated at admission, as long as it is not related to the previous hospitalization in the same hospital. Such infections can be caused by several microorganisms, especially bacteria and fungi. Therefore, this study aimed to verify the most prevalent microorganisms, their sensitivity profile, as well as the age group and gender of individuals affected by community-origin urinary infection diagnosed in a University Hospital of Rio Grande do Norte, from 2015 to 2017. Therefore, a descriptive, epidemiological, analytical and retrospective study was developed, and the data collected from the computer files of the microbiology laboratory of that hospital. The age group most affected for females was between 20 and 29 years and for males was 70 to 79 years and 80 to 89 years, with females being the most affected in the three years studied, accounting for more than 90% of cases. The most frequent pathogen isolated in urine was Escherichia coli for the same period. In verifying the sensitivity tests for the E. coli strains, it was found that 100% of the E.coli strains, regardless of the year, were sensitive to the antibacterial meropenem and cefoxitin. Large percentages of resistance were observed to antibiotics ampicillin, sulfamethoxazole + trimetropime, tetracycline and cephalotin. Worrying results were observed regarding the isolation of strains resistant to fluoruquinolones, antibacterial strains highly prescribed empirically in medical practice. Then, the study becomes relevant because it aims to contribute to minimize these infections and bring wide benefits, because it will be possible to determine a microbial profile for physicians and identify the best way for the prevention, control and correct use of medication, reducing the use of antimicrobials in an erroneous way, adopting the rational use of drugs, especially broad-spectrum antibacterials such as quinolones, reducing the selective pressure and reducing bacterial resistance.
