Healthcare-associated infections (HAIs) related to the use of medical devices are more likely to be antibiotic resistant than HAIs that result from surgical procedures, according to a report from the US Centers for Disease Control and Prevention's (CDC's) National Healthcare Safety Network (NHSN).
The study, published in Infection Control & Hospital Epidemiology, analysed data from central line-associated bloodstream infections, catheter-associated urinary tract infections, ventilator-associated events, and surgical site infections (SSIs) reported from US inpatient healthcare facilities between 2015-2017 among adult patients (≥18 years).
Overall, 5626 facilities performed adult HAI surveillance during this period, most of which were general acute-care hospitals with
Percentages of pathogens with non-susceptibility (%NS) to selected antimicrobials were calculated for each HAI type, location type, surgical category, and surgical wound closure technique.
Pathogens varied by HAI and location type.
Escherichia coli (18%), Staphylococcus aureus (12%), and Klebsiella spp (9%) were the three most frequently reported pathogens.
The %NS for most pathogens was significantly higher among device-associated HAIs than SSIs. For instance, 48% of tested Staphylococcus aureus isolated from device-associated infections were methicillin resistant (MRSA), compared with 41% among those isolated from SSIs.
In addition, pathogens from long-term acute care hospitals had a significantly higher %NS than those from general hospital wards.
