Insights
Prospective audit with real-time feedback significantly reduced vancomycin use in hospitalized children. This intervention lowered vancomycin days of therapy (DoT) and associated pharmacy costs.
Area of Science:
- Pediatric Infectious Diseases
- Antimicrobial Stewardship
- Health Services Research
Background:
- Vancomycin is frequently used in pediatric hospital settings.
- Evaluating interventions to optimize antibiotic use is crucial for patient outcomes and cost-effectiveness.
Purpose of the Study:
- To assess the impact of prospective audit with real-time feedback on vancomycin utilization.
- To determine the effect of this intervention on pharmacy costs in a pediatric hospital.
Main Methods:
- A prospective audit and feedback intervention was implemented in 2012 at Monroe Carell Jr Children's Hospital at Vanderbilt (MCJCHV).
- Vancomycin use (days of antibiotic therapy per 1000 patient-days) was compared before and after the intervention.
- Interrupted time series analysis was used to compare vancomycin use at MCJCHV with academic children's hospitals with and without established antimicrobial stewardship programs (ASPs).
Main Results:
- Monthly vancomycin use decreased significantly from 114 to 89 DoTs/1000 patient-days post-intervention (P < .0001).
- No significant difference in the trend of vancomycin use was observed when compared to institutions with ASPs.
- Vancomycin use at MCJCHV was significantly lower compared to children's hospitals without ASPs (P < .001).
Conclusions:
- Prospective audit with real-time feedback effectively reduced vancomycin use in a pediatric hospital setting.
- The intervention led to a significant decrease in vancomycin days of therapy and associated costs.
- This strategy demonstrates the value of antimicrobial stewardship interventions in optimizing antibiotic prescribing practices.
Introduction:
The use of vancomycin is common among hospitalized children. We sought to evaluate the impact of prospective audit with real-time feedback on vancomycin use and pharmacy costs.
Methods:
Vancomycin use was evaluated at Monroe Carell Jr Children's Hospital at Vanderbilt (MCJCHV) before and after the implementation of prospective audit with intervention and feedback to providers in 2012. Antibiotic use was compared to academic children's hospitals with established antimicrobial stewardship programs (ASPs). Two similar pediatric academic institutions without an ASP were used as nonintervention controls. Analysis of monthly days of antibiotic therapy (DoT) per 1000 patient-days was performed by interrupted time series analysis.
Results:
Monthly vancomycin use decreased from 114 DoTs/1000 patient-days to 89 DoTs/1000 patient-days ( P < .0001). We did not find significant differences in the slope of change in vancomycin use between MCJCHV and institutions with ASPs either before or after the intervention ( P = .86 and P = .71, respectively). When compared to children's hospitals without ASPs, the use of vancomycin was significantly lower at MCJCHV ( P < .001).
Conclusion:
The use of vancomycin at academic children's hospitals with an ASP is declining. In our experience, prospective audit with real-time intervention and feedback to providers significantly reduced the use and costs associated with vancomycin.
