Avaliação da antibioticoprofilaxia em pacientes cirúrgicos no HospitalUniversitário Gaffrée e Guinle. This complication is one of the main forms of infections related to health care in Brazil, as demonstrated in a study conducted by the Ministry of Health, which observed SSI in 11% of all surgical procedures analyzed 4 . SSI occupies the third place in frequency among all the others, accounting for about 15% of all infectious processes observed in hospitalized patients 2,5 .Moreover, this type of complication involves financial burden to the patient, to the hospital and to the healthcare system. These facts make SSI an important public health problem and therefore a target for improving the quality of care to the patient who is candidate to surgical treatment 6 .Antibiotic prophylaxis is part of a set of measures that aim to reduce SSI incidence. The main aim of antibiotic prophylaxis is to reduce the bacterial load in the wound, to assist the natural host defenses in preventing SSI Efforts have been undertaken to establish protocols to guide the appropriate use of antibiotic prophylaxis for SSI prevention, whose goal is to provide health professionals with a standardized approach to the safe, effective and rational use of antimicrobials 9 .The aim of this study was to evaluate the use of antibiotic prophylaxis in surgical patients at the Gaffrée e Guinle University Hospital, in the city of Rio de Janeiro.

METHODSThis is a prospective study of a cohort composed of patients undergoing elective surgical procedures between January and September 2014. Of the 283 patients who were initially candidates to participate in the study, we excluded 27 because they do not meet the established criteria, the final sample thus comprising 256 cases.We conducted the study at the Gaffrée e Guin- The sample calculation considered the likelihood of appropriate use of antibiotic prophylaxis to 50%, with 95% confidence interval, and type I error <5%.Thus, the estimated sample of 232 patients.Data collection included three different times:preoperative time, perioperative one and up to the seventh postoperative day; we performed the record in a standardized form. In cases of administered antibiotic, we
STATISTICAL ANALYSISWe performed univariate analyzes by means of simple frequencies in order to describe the study sample, and bivariate analysis to detect differences in the distribution of independent variables for each outcome of interest, using the chi-square test. We also employed multivariate logistic regression, including the indepen-
