HealthDay News — In two reports published online Nov. 25 in Infection Control & Hospital Epidemiology, authors present updated summaries of common pathogens and antimicrobial resistance patterns among health care-associated infections (HAIs) in adult and pediatric patients.
Lindsey M. Weiner-Lastinger, M.P.H., from the U.S. Centers for Disease Control and Prevention in Atlanta, and colleagues examined device-associated HAIs reported from adult location types, as well as surgical site infections (SSIs) among patients ≥18 years. The researchers found that the three most frequently reported pathogens were Escherichia coli, Staphylococcus aureus, and Klebsiella spp (18, 12, and 9 percent, respectively). Pathogens varied by HAI and location type; a distinct pathogen distribution was seen in oncology units versus other settings. The percentage of pathogens with nonsusceptibility (%NS) to selected antimicrobials was higher among device-associated HAIs than SSIs.
In a second study, Weiner-Lastinger and colleagues analyzed device-associated HAIs reported from pediatric patient care locations as well as SSIs among patients aged <18 years. The researchers found that the three most commonly reported pathogens were Staphylococcus aureus, Escherichia coli, and coagulase-negative staphylococci (15, 12, and 12 percent, respectively). Variation was noted in pathogens and the %NS by HAI type, location type, and/or surgical category. Antimicrobial nonsusceptibility was less prevalent in pediatric HAIs than adult HAIs overall.
“These data show that the threat of exposure to bacteria that are resistant to antibiotics extends across the nation,” Weiner-Lastinger said in a statement. “The data also serve as an urgent call for health care facilities and public health agencies to intensify their efforts to prevent the emergence and spread of antimicrobial resistance.”
