Background:

Traditionally, the antibiogram (ABG) is generated manually and is limited in scope. There is an increased demand for an expanded spectrum ABG.

Objective:

Cumulative ABG reports help guide clinical decisions in using appropriate antimicrobial therapy in healthcare facilities. We designed and validated an expanded ABG to include separate reports for the various specimen sources and patient care units.

Methods:

In this study, microbial culture and susceptibility results available in SafetySurveillor® (Premier Inc., Charlotte, NC) were analyzed based on the 2002 NCCLS M39-A guidelines. The automated analysis included the generation of ABG reports for various patient care units (primary) and further by various specimen sources (secondary). The ABG reports were presented in a tabular format. In addition to indicating percent susceptibility, numerator and denominator values were also presented in these reports. The values for each organism/antibiotic combination were validated using other reports within the software.

Results:

The automated ABG reports were generated and displayed in the software in a tabular format. In addition to a hospital-wide antibiogram, the following reports were generated: outpatient, inpatient, adult ICU, general medical/surgical, pediatrics, and pediatric ICU. Furthermore, specimen source specific ABG reports for each patient care unit included blood, urine, non-urine, wound, central nervous system, upper respiratory tract, and lower respiratory tract. The percent susceptibility results were validated and were in agreement with the number of isolates in both the numerator and denominator.

Conclusions:  

The automation of an expanded cumulative antibiogram helps in making reliable reports available in a timely manner. More importantly, automation and standardization of ABG reports will allow for cross-facility comparison. By leveraging technology in antibiogram creation, healthcare facilities are able to eliminate manual and resource consuming methods for generating these reports.
