Implementing outpatient antimicrobial stewardship in a primary care office through ambulatory care pharmacist-led audit and feedback.

OBJECTIVES: This study aimed to determine the impact of a pharmacist-led antimicrobial stewardship program (ASP) intervention on outpatient antibiotic prescribing for upper respiratory tract infections (URIs) and urinary tract infections (UTIs) in a primary care office. The primary outcome of this study was to characterize antibiotic prescribing over time. Secondary outcomes included describing ambulatory care pharmacist (ACP) workload and types of feedback given. METHODS: A retrospective pilot study was conducted within a primary care office. The office included a 0.6 full-time equivalent ACP and is part of a health system supported by a pharmacist and a physician co-led ASP. Education and guidelines were provided by the ACP and ASP leads before the intervention period August 2017-February 2018. The ACP provided bi-weekly audit of all URI and UTI prescriptions and written feedback to prescribers. RESULTS: During the 7-month intervention period, 1107 prescriptions were audited by the ACP, 825 URI and 282 UTI. The most common reasons for feedback included inappropriate agent (26.3%) or prolonged duration of therapy (24.3%). Guideline-concordant agent prescribed for a UTI increased from 20% at baseline to a median of 69.2%, whereas duration increased from 55% to 70.4%. Guideline-concordant agent prescribed for a URI increased from 43.3% to 86.8%, whereas the median duration of therapy decreased from 10 to 7 days. CONCLUSION: An ACP-led ASP intervention within a primary care office incorporating audit and feedback improved antibiotic prescribing for URIs and UTIs, including prescribing antibiotics when indicated, guideline-concordant antibiotic selection, and duration of therapy. Pharmacists practicing in ambulatory care settings may serve a vital role in leading successful outpatient ASP interventions.

Comparison of Diagnosis and Prescribing Practices Between Virtual Visits and Office Visits for Adults Diagnosed With Sinusitis Within a Primary Care Network.

BACKGROUND: Many antibiotics prescribed in the outpatient setting result from upper respiratory tract infections (URTIs); however, these infections are often viral. Virtual visits have emerged as a popular alternative to office visits for URTIs and may be an important target for antimicrobial stewardship programs. METHODS: This retrospective cohort study evaluated adult patients diagnosed with sinusitis treated within a single primary care network. The primary objective was to compare guideline-concordant diagnosis between patients treated via virtual visits vs in-office visits. Guideline-concordant bacterial sinusitis diagnosis was based on national guideline recommendations. Secondary objectives included comparing guideline-concordant antibiotic prescribing between groups and 24-hour, 7-day, and 30-day revisits. RESULTS: A total of 350 patients were included in the study, with 175 in each group. Patients treated for sinusitis were more likely to receive a guideline-concordant diagnosis in the virtual visit group (69.1% vs 45.7%; P < .001). Additionally, patients who completed virtual visits were less likely to receive antibiotics (68.6% vs 94.3%; P < .001). Guideline-concordant antibiotic selection was similar between groups (67.5% vs 64.8%; P = .641). The median duration of therapy in both groups was 10 days (P = .88). Patients completing virtual visits were more likely to revisit for sinusitis within 24 hours (8% vs 1.7%; P = .006) and within 30 days (14.9% vs 7.4%; P = .027). CONCLUSIONS: In adult patients presenting with sinusitis, care at a virtual visit was associated with an increase in guideline-concordant diagnosis and a decrease in antibiotic prescribing compared with in-office primary care visits. Virtual visit platforms may be a valuable tool for antimicrobial stewardship programs in the outpatient setting.
