Improving the antibiotic duration of therapy with the implementation of antimicrobial lanyard cards and education in a regional hospital

Background

There is increasing evidence to support reducing antibiotic duration of therapy (DoT). The Therapeutic Guidelines: Antibiotic (version 16 [TG]) have been updated accordingly. However, these recommendations are not consistently followed.

Aim

The project aimed to reduce antibiotic DoT for common infections using antimicrobial lanyard cards and education.

Method

A retrospective pre- and post-implementation audit was undertaken to examine whether antimicrobial stewardship education and lanyard cards defined DoT per infection and severity in accordance with the TG improved antibiotic DoT for common respiratory, urinary, abdominal, and skin infections. Cards were distributed to doctors and pharmacists, with education delivered by an antimicrobial stewardship (AMS) pharmacist. This project was exempt due to the local policy requirements that constitute research by the Darling Downs Hospital and Health Service Human Research Ethics Committee (Reference no: EX/2022/QTDD/86644). The justification for this ethics exemption was as follows: the study conformed with the National Health and Medical Research Council (NHMRC) Ethical considerations in quality assurance and evaluation activities; education was incorporated as part of routine, scheduled sessions ran at Toowoomba hospital and staff were provided with information on the project as part of the education; consent was not required from staff to attend the education nor for using the lanyard cards; the research did not include any assessment of the education program, use of lanyard cards, or involvement of staff.

Results

For all patients an improvement was found in the percentage of antibiotics prescribed per the TG (55–72%, p = 0.0095). This included statistically significant differences for respiratory (42–89%, p = 0.0002), but not for urinary (87–91%, p = 0.99), skin (58–77%, p = 0.3039), or abdominal infections (48–44%, p = 0.6990). The mean total excess treatment days decreased across all infections from 1.86 to 0.95 days (p = 0.0036, 95% confidence interval = −1.52 to −0.30).

Conclusion

The introduction of antibiotic DoT cards, with AMS education, can improve antimicrobial prescribing in line with the TG in a regional hospital.
