MDR A. baumannii was defined as resistance to at least two b-lactam antimicrobials (including ceftazidime, factors; the results being presented as an odds ratio (OR with a 95% confidence inter-val (95% logistic regression analysis, using the backward likelihood ratio selection method, was used to assess independent factors related to contracting MDR A. baumannii bacteremia and those related to p-value ≤ was considered statistically significant.
RESULTS
During the 3-year period of the study, there were 84 episodes in 79 patients with positive blood cultures for A. baumannii, indicating an incidence of cases per 10,000 hospital these, the incidences of MDR- and PDR- A. bau-mannii bacteremia were and cases per 10,000 hospital admissions, respec- was an increasing trend in antimicrobial resistance to several drugs during the 3-year study (Fig 1.
Medical records were available for 65 cases (%.Of these, 16 cases were excluded from the study due to contami-nation (6 cases, mixed infection (9 cases and transfer to another hospital (1 case. Among the remaining 49 cases, 25 (51% and 24 cases (49%, respectively, had non-MDR and MDR A. baumannii bacteremia and 15 of the 24 MDR A. baumannii cases (% had PDR A. baumannii infection.
