Background The Centers for Disease Control and Prevention (CDC) proposed standard definitions for acquired resistance in bacterias. Resistant bacteria were categorized as multidrug-resistant (MDR), extensively drug-resistant (XDR) and pandrug-resistant (PDR). This study describes the incidence of Gram-negative MDR, XDR and PDR in 12 private and adult intensive care units (ICU's) from Belo Horizonte, Minas Gerais, the sixth most populated city in Brazil, with approximately 3 million inhabitants. Methods Data were collected between January/2013 to December/2017 from 12 ICU's. The hospitals used prospective healthcare-associated infections (HAI) surveillance protocols, in accordance to the CDC. Antimicrobial resistance from six Gram-negatives, causing nosocomial infections, were evaluated: Acinetobacter sp. Klebsiella sp. Proteus sp. Enterobacter sp. Escherichia coli, and Pseudomonas sp.. We computed the three categories of drug-resistance (MDR+XDR+PDR) to define benchmarks for the resistance rate of each Gram-negative evaluated. Benchmarks were defined as the superior limits of 95% confidence interval for the resistance rate. Results After a 5 year surveillance, 6,242 HAI strains were tested: no pandrug-resistant bacteria (PDR) was found. Acinetobacter sp. was the most resistant Gram-negative: 206 strains from 1,858 were XDR (11%), and 1,638 were MDR (88%). Pseudomonas sp. : 41/1,159 = 3.53% XDR; 180/1,159 = 15.53% MDR. Klebsiella sp. : 2/1,566 = 0,1% XDR; 813/1,566 = 52% MDR. Proteus sp. : 0/507 = 0% XDR; 163/507 = 32% MDR. Enterobacter sp. : 0/471 = 0% XDR; 148/471 = 31% MDR. Escherichia coli : 0/681 = 0% XDR; 157/681 = 23% MDR. Benchmarks for the global resistance rate of each Gram-negative (MDR+XDR+PDR): Acinetobacter sp. = 92%; Klebsiella sp. = 62%; Proteus sp. = 40%; Enterobacter sp. = 48%; Escherichia coli = 33%; Pseudomonas sp. = 30%. Conclusion This study has calculated the incidence of Gram-negative MDR, XDR and PDR, and found a higher incidence of MDR Acinetobacter sp. with an 88% multiresistance rate. Henceforth, developing countries healthcare institutions must be aware of an increased risk of infection by Acinetobacter sp.. Benchmarks have been defined, and can be used as indicators for healthcare assessment. Disclosures All authors: No reported disclosures. [ABSTRACT FROM AUTHOR] |
