Prevalence and appropriateness of in-person versus not-in-person ambulatory antibiotic prescribing in an integrated academic health system: a cohort study.
This retrospective cohort study examined the prevalence and appropriateness of all ambulatory antibiotic prescribing in an integrated health delivery system in the United States. The authors looked at prescribing at in-person visits and not-in-person visits (e.g. telephone, refills). Prescribing was divided into the following 5 appropriateness groups: 1) chronic antibiotic use; 2) antibiotic-appropriate; 3) potentially antibiotic-appropriate; 4) non-antibiotic-appropriate; and 5) not associated with a diagnosis. Over the 4-year study period, there were 714,057 antibiotic prescriptions ordered for 348,739 unique patients by 2,391 clinicians in 467 clinics with a patient population with a mean age of 41 years, 61% female and 78% White. Clinicians were mostly women (58%); were 78% physicians; and of those physicians were 42% primary care, 39% medical specialists, and 12% surgical specialists. The vast majority (81%) of antibiotics were prescribed at in-person visits, and 19% were not in-person visits (10% telephone, 5% orders only, and 3% refill encounters). Prescribing appropriateness was divided into 16% for chronic use, 15% antibiotic-appropriate, 39% potentially antibiotic-appropriate, 22% non-antibiotic-appropriate, and 8% not associated with a diagnosis. Prescription of antibiotics not-in-person were more likely to be chronic (20% versus 15%); less likely to be associated with appropriate or potentially appropriate diagnoses (30% versus 59%) or non-antibiotic-appropriate diagnoses (8% versus 25%); and more likely to be associated with no diagnosis (42% versus <1%).

Is the number of prescriptions an appropriate metric for outpatient antimicrobial consumption? A comparison between the prescription counts and days supplied.
Monitoring antibiotic use is essential for encouraging the appropriate use of antibiotics. However, defining appropriate metrics presents multiple challenges. The purpose of this study was to compare 2 metrics for antibiotic outpatient consumption at the Veterans Health Administration (VHA) pharmacies: the number of prescriptions in EMRs and the number of dispensed days, or days supplied. During the study period, 13,373,460 clinic visits (5.0%) of the 265,613,607 total clinic visits had an antibiotic prescription, and the total of days supplied was 182,793,572. The study found that the mean days supplied per prescription continued mainly unchanged during the study period. Comparing the number of prescriptions and days supplied normalized by the number of clinic visits, these 2 metrics changed in parallel, with only minor differences from 2010 to 2019. When the researchers focused on short-term prescriptions usually utilized for acute illnesses (14 days or less), prescription number and days supplied reflected an increasing discrepancy. The number of prescriptions underestimated the decline compared to days supplied. Alternatively, long-term prescriptions (15 days or more) reflected the opposite discrepancy. For comparisons between facilities, the researchers found considerable differences in rankings of healthcare systems based on the 2 metrics.

The AHRQ Safety Program for Improving Antibiotic Use in Practice.
The Agency for Healthcare Research and Quality (AHRQ) Safety Program for Improving Antibiotic Use was an antibiotic stewardship intervention implemented across the United States in 2020 in 389 primary and urgent care practices. The AHRQ Toolkit to Improve Antibiotic Use in Ambulatory Care has been created based on integration of the educational material used in the AHRQ safety program and the experiences of the participating practices. The toolkit includes presentations on developing, implementing, and maintaining antibiotic stewardship activities; a gap analysis tool; and a guide to accessing and reporting antibiotic prescription data. Practices can use these tools to build their antibiotic stewardship teams and begin working on programs. Improving antibiotic prescribing in ambulatory care is a critical need. Utilizing the AHRQ Toolkit to Improve Antibiotic Use in Ambulatory Care can assist practices in achieving their antibiotic stewardship goals.

Decline in oral antimicrobial prescription in the outpatient setting after nationwide implementation of financial incentives and provider education: an interrupted time-series analysis.
Researchers examined the impact of financial incentives to providers and provider education on overall antimicrobial prescription rates. They also analyzed how nationwide outpatient antimicrobial stewardship interventions in cases where antimicrobials were deemed unnecessary for uncomplicated respiratory infections and acute diarrhea affected different age groups before and after their implementation. The results indicated that prescription rates for all age groups showed a downward trend throughout the study period. Substantial reductions in prescription rates were observed among infants under 2 years, while provider education immediately reduced prescription rates in all age groups uniformly. Interventions did not affect the long-term trend for any age group.
