Antimicrobial stewardship: Prescribing across the primary care health professions

We examined the patterns of antibiotic prescribing by medical and non-medical prescribers (dentists, nurse practitioners, and midwives) in Australia. We explored trends in the dispensed use of antibiotics (scripts and defined daily dose [DDD] per 1000 population/day) by Australian prescribers over the 12-year period, 2005 –2016. We obtained data on dispensed prescriptions of antibiotics from registered health professionals subsidized on the Pharmaceutical Benefits Scheme (PBS). There were 216.2 million medical and 7.1 million non-medical dispensed prescriptions for antibiotics over 12 years. The top four antibiot ics for medical prescribers were doxycycline; amoxicillin, amoxicillin plus clavulanic acid, and cefalexin, constituting 80% of top 10 use in 2005 and 2016; the top three for non-medical were amoxicillin, amoxicillin plus clavulanic acid and metronidazole (84% of top 10 use in 2016). The proportiona l increase in antibiotic use was higher for non-medical than medical prescribers. While medical prescribers preferentially prescribed broad-spectrum and non-medical prescribers moderate-spectrum antibiotics, there was a large increase in the use of broad-spectrum antibiotics over time by all prescri bers. One in four medical prescriptions were repeats. Overprescribing of broad-spectrum antibiotics conflicts with national antimicrobial stewardship initiatives and guidelines. The proportional higher increase in antibiotic use by non-medical prescribers is a concern. To ...
