Abstract
BACKGROUND: Approximately 20%-50% of antimicrobial use in hospitals is inappropriate. Limited data exist on the effect of frontline provider engagement on antimicrobial stewardship outcomes.
METHODS: A three-arm pre-post quality improvement study was conducted on three adult internal medicine teaching services at an urban academic hospital. Data from September through December 2016 were compared to historic data from corresponding months in 2015. Intervention arms were (1) Educational bundle (Ed-only); (2) Educational bundle plus antimicrobial stewardship rounds twice weekly with an infectious disease-trained clinical pharmacist (Ed+IDPharmDx2); and (3) Educational bundle plus internal medicine-trained clinical pharmacist embedded into daily attending rounds (Ed+IMPharmDx5).
RESULTS: Total antibiotic use decreased by 16.8% (p < 0.001), 6.8% (p = 0.08), and 33.0% (p < 0.001) on Ed-only, Ed+IDPharmDx2, and Ed+IMPharmDx5 teams, respectively. Broad-spectrum antibiotic use decreased by 26.2% (p < 0.001), 7.8% (p = 0.09), and 32.4% (p < 0.001) on the Ed-only, Ed+IDPharmDx2, and Ed+IMPharmDx5 teams, respectively. Duration of inpatient antibiotic therapy decreased from 4 to 3 days on the Ed+IMPharmDx5 team (p = 0.01). Length of stay for patients who received any antibiotic decreased from 9 to 7 days on the Ed-only team (p < 0.001) and from 9 to 6 days on the Ed+IMPharmDx5 team (p < 0.001). There was no significant change in 30-day readmission to the same facility, transfer to ICU, or in-hospital mortality for any team.
CONCLUSION: Multidisciplinary, frontline provider-driven approaches to antimicrobial stewardship may contribute to reduced antibiotic use and length of hospital stay.
