Since antimicrobial resistance has increased steadily and varies by geographic location and patient population, the availability of up-to-date cumulative antimicrobial susceptibility is crucial. These data are also essential to monitor emerging trends in resistance at the local level to support clinical decision-making, evaluate infection control interventions, inform and participate in antimicrobial stewardship efforts, optimize microbiology susceptibility testing and reporting, and guide Pharmacy and Therapeutics Committee formulary decisions.

Enrollment in this study assists laboratories in meeting the CAP Laboratory Accreditation Program Checklist statement MIC.21946, Cumulative Susceptability Data, and The Joint Commission Antimicrobial Stewardship Standard, MM 09.01.01.


This study will assist the laboratory and health care facility with antimicrobial stewardship by ongoing comparison and trending of cumulative susceptibility rates for common microorganisms within a facility over time and between participating facilities.

Data Collection

Commulative susceptability data for each year from 2018 to 2020 will be collected for select microorganisms including Acinetobacter baumannii, Enterobacter cloacae complex, Escherichia coli, Klebsiella, pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Enterococcus species and Staphylococcus aureus. Standardized data collection methods will be used by all participants in accordance with recommended guidelines.

Performance Indicators

  • Annual antimicrobial susceptibility rate for select microorganisms and antibiotics in 2020.

  • Trend of antimicrobial susceptibility rates from 2018 to 2020 for specific microorganisms.

*The CAP requires accredited laboratories to have a quality management plan that covers all areas of the laboratory and includes benchmarking key measures of laboratory performance (GEN.13806, GEN.20316, COM.04000). The Joint Commission requires accredited hospitals to regularly collect and analyze performance data (PI.01.01.01, PI.02.01.01). CLIA requires laboratories to monitor, assess, and correct problems identified in preanalytic, analytic, and postanalytic systems (§493.1249, §493.1289, §493.1299).
