Pathogen Profile

Multidrug-resistant Pseudomonas aeruginosa

Pseudomonas aeruginosa is a common cause of healthcare-associated infections including pneumonia, bloodstream infections, urinary tract infections, and surgical site infections. Some P. aeruginosa are becoming more resistant to even antibiotics of last resort, and are described as multidrug-resistant.

Geographic Location

#permalink to section

Antimicrobial resistance varies by location, driven by a number of factors, including antibiotic use and infection control practices in individual healthcare facilities, the underlying health and age of the patient population, and regional spread from nearby locations.

Changes Over Time in Multidrug resistance Among Pseudomonas aeruginosa

#permalink to section

This graph displays percent antimicrobial resistance from 2011 to 2022 for all event types. Blank areas of the chart represent 0% resistance, indicating that zero resistant pathogens were reported for the selected year, phenotype, and HAI type. “Insufficient data” indicates that less than 20 pathogens were isolated and tested for resistance.

Due to definition changes, caution should be used when reviewing this phenotype over time.

Infectious Event Type

#permalink to section

Modern healthcare employs many types of devices (for example, catheters, ventilators, etc.) and procedures to treat patients and to help them recover. Infections can be associated with the devices used during medical procedures. These healthcare-associated infections (HAIs) include central line-associated bloodstream infections and catheter-associated urinary tract infections. Infections may also occur at surgery sites, known as surgical site infections.

Multidrug resistance Among Pseudomonas aeruginosa by HAI Type

This graph displays percent antimicrobial resistance by HAI type in 2022.

Healthcare Facility Type

#permalink to section

The setting or type of healthcare facility can influence the types of procedures and prevention measures that are related to healthcare-associated infections and antimicrobial resistance.

Footnotes

  • HAIs include Catheter-associated Urinary Tract Infections (CAUTI), Central Line-associated Bloodstream Infections (CLABSI), and Surgical Site Infections (SSI).
  • CI (Confidence Interval) - The national, regional, and state-level data included in Antimicrobial Resistance information are displayed with 95% confidence intervals around the percent resistance, which were calculated using a mid-P exact test and are an indication of precision.
  • Map legends are classified using the Jenks Natural Breaks method.
  • The definition for this phenotype underwent changes in 2021. For more information, refer to the AR&PSP Phenotype Definitions
