Area of Science:

  • Infectious Diseases
  • Clinical Pharmacy
  • Health Informatics

Background:

  • Effective antimicrobial prescribing is crucial for patient outcomes and combating antimicrobial resistance.
  • Clinicians utilize various resources to inform antimicrobial selection and dosing.
  • Understanding resource utilization can identify opportunities for improved decision support.

Purpose of the Study:

  • To identify the resources healthcare providers use when prescribing antimicrobials.
  • To explore factors associated with the use of external resources in antimicrobial decision-making.
  • To assess the potential utility of point-of-electronic-order-entry decision support.

Main Methods:

  • Telephone surveys were conducted with 157 clinicians immediately after antimicrobial prescription.

  • Data collected included the use of external resources (consultation, print, digital) and prescriber characteristics.
  • Multivariate analysis examined associations between prescriber factors and external resource use.

    • Main Results:

    • 55% of prescribers used at least one external resource; 45% relied solely on personal experience.
    • Consulting another person (38%) and using print/digital resources (34%) were common.
    • Use of external resources was linked to being on a medical service (OR 2.99) or being an intern (OR 13.65).

    Conclusions:

    • A significant proportion of clinicians utilize external resources for antimicrobial prescribing.
    • Interns and those on medical services were more likely to seek external guidance.
    • The majority of providers (80%) found point-of-electronic-order-entry information helpful, suggesting potential for improved antimicrobial stewardship.
