Summary

Antibiotic prescribing in the Acute Medicines Assessment Unit (AMAU) shows overuse, particularly intravenous routes, with many unproven infections. Optimizing treatment duration and antibiotic selection based on culture results can improve prescribing practices.

Area of Science:

  • Internal Medicine
  • Infectious Diseases
  • Clinical Pharmacy

Background:

  • Antibiotic stewardship is crucial in hospital settings to combat antimicrobial resistance.
  • The Acute Medicines Assessment Unit (AMAU) is a key area for initial antibiotic management of acutely unwell patients.

Purpose of the Study:

  • To evaluate the quality and continuity of antibiotic treatment in the AMAU.
  • To assess empirical antibiotic prescribing, administration, adherence to policy, and microbiological investigation utilization.

Main Methods:

  • A prospective study was conducted over 3 months in the AMAU at Aberdeen Royal Infirmary.
  • All patients initiated on empirical antibiotics upon admission were followed until discharge.

Main Results:

Related Experiment Videos

  • 17% of 1303 admitted patients received empirical antibiotics, with 52% adhering to hospital policy.
  • Appropriate specimens were collected from 77% of patients; 29% had significant microbial growth.
  • 49% of patients with significant growth received inappropriate empirical regimens, and 55% were not switched to appropriate antibiotics.

Conclusions:

  • Significant overuse of antibiotics, especially intravenous, was observed in the AMAU, often without clear infection indicators.
  • Treatment duration and antibiotic selection could be improved by considering culture results and sepsis profiles.
  • Implementing an early switch policy and optimizing prescribing based on microbiological data is recommended for unproven infections.
