Implementing TheraTrac 2 software and pharmacist education improved antimicrobial therapy interventions, leading to significant cost savings and reduced length of hospital stay for patients.

Area of Science:

  • Clinical Pharmacy
  • Health Informatics
  • Infectious Diseases

Background:

  • Antimicrobial therapy interventions can improve patient outcomes.
  • Effective interventions require timely access to susceptibility testing data.
  • Current manual processes for reviewing susceptibility data can be inefficient.

Purpose of the Study:

  • To prospectively evaluate the impact of an improved intervention program.
  • To assess the effectiveness of TheraTrac 2 software for electronic linkage of susceptibility results.
  • To determine the effect of pharmacist education on microbiologic topics.

Main Methods:

  • Prospective study comparing a new intervention group with a control group.
  • Study group utilized TheraTrac 2 software for immediate electronic access to susceptibility data.

  • Control group used manual review of hard-copy susceptibility testing data.
  • Three analyses were performed: intervention-only, diagnosis-related group (DRG) matched, and severity-adjusted DRG matched.

    • Main Results:

    • Analysis B (DRG-matched) showed a statistically significant decrease in length of stay (2.7 days, P=0.035) and variable direct costs ($2,626, P=0.008).
    • Analysis C (severity-adjusted DRG-matched) indicated reduced length of stay (1.2 days) and variable direct costs ($1,466).
    • While not statistically significant in Analysis A, the study group showed trends towards decreased mortality and length of stay.

    Conclusions:

    • The implementation of the TheraTrac 2 program resulted in substantial cost savings.
    • Improved antimicrobial stewardship through technology and education can enhance efficiency.
    • Further research may be warranted to confirm impact on mortality rates.
