Vancomycin prescribing at a Brazilian hospital often did not follow guidelines, leading to resistance concerns. Improved education and infectious disease specialist review are needed for appropriate vancomycin use.

Area of Science:

  • Infectious Diseases
  • Hospital Pharmacy
  • Antimicrobial Stewardship

Background:

  • Emergence of vancomycin-resistant bacteria poses a significant public health threat.
  • Hospital Infections Control Practices Advisory Committee (HICPAC) guidelines aim to optimize vancomycin prescribing.
  • Evaluating adherence to these guidelines is crucial for antimicrobial stewardship.

Purpose of the Study:

  • To assess vancomycin utilization patterns at Uberlândia University Hospital in Brazil.
  • To determine the extent of adherence to HICPAC guidelines for vancomycin prescribing.
  • To identify factors associated with non-adherence and the emergence of resistant strains.

Main Methods:

  • A prospective study involving 31 patients receiving vancomycin over 10 months.

  • Nasal and rectal cultures were performed to monitor for Vancomycin-Resistant Enterococci (VRE) and Methicillin-Resistant Staphylococcus aureus (MRSA).
  • Patient records were reviewed to collect demographic and clinical data, and assess HICPAC guideline adherence.
  • Main Results:

    • 68% of vancomycin use (21/31 patients) did not adhere to HICPAC guidelines, primarily due to empirical prescribing without documented need.
    • Non-adherence was higher when vancomycin was used without Infectious Diseases (ID) specialist approval (81%) compared to with approval (53%).
    • Despite non-adherence, empirical vancomycin use approved by ID specialists in severely ill patients (75%) may have been appropriate, though outside guidelines.

    Conclusions:

    • Significant non-adherence to HICPAC vancomycin prescribing guidelines was observed.
    • There is a critical need for enhanced education on appropriate vancomycin use.
    • Increased review by ID specialists, particularly on medicine services, is recommended to improve vancomycin stewardship.
