Abstract
BACKGROUND AND OBJECTIVE: Adequate empirical treatment should be established for treatment urinary tract infections, considering the prevalence of the most frequent microorganisms in each geographic area and their susceptibility to different antibiotics. The objective of the study is to analyze the epidemiology of UTIs in our Health Area as well as to understand the antibiotic susceptibility of the most prevalent isolated microorganisms to guide empirical treatment. The objective was to establish a reasoned system for recommending ITU empirical therapy, based on the microorganisms causing episodes assisted in a Regional Hospital, knowing their antibiotic susceptibility. PATIENTS AND METHODS: A descriptive-retrospective study was carried out based on the results of 12,204 urine cultures of the year 2018. The overall empirical activity of the antibiotics tested was calculated, differentiating between episodes of the community and of in patients, adults and children. RESULTS: Escherichia coli was the most frequently isolated microorganism in all studied groups. The following microorganisms in frequency, in adults, were Enterococcus faecalis, Klebsiella pneumoniae and yeasts (8%). In the group of children these were Enterococcus faecalis and Proteus mirabilis. There was no difference in the activity of antibiotics against Escherichia coli, in adults or in children, of the community or in patients, with sensitivityto fosfomycin and nitrofuranto in greater than 96%; at imipenem and piperacillin-tazobactam greater than 94% and third generation cephalosporins greater than 90%. However, the overall empirical activity, without distinction by microorganism, was for fosfomycin 77.96-80.60% in adults and 92.73-94.50% in children; to prevent 77.70-78.74% in adults and 92.36-91.28% in children; for piperacillin-tazobactam of 77.57-80.03% in adults and 89.09-94.04% in children; and for cefotaxime of 53.28-54.76% in adults and 68.73-74.77% in children. CONCLUSIONS: Fosfomycin, piperacillin-tazobactam or imipenem were the best option for empirical treatment without covering all episodes in adults. Each Center must establish a reasoned profile of empirical treatment of the infection, which should also take into account risk factors for a microorganism and clinical severity.
