Introduction:
Antibiotic misuse and overuse, among other factors, are the main drivers of increased antimicrobial resistance. Although cefalexin is generally recommended as a second-line agent, recent trends in Aotearoa New Zealand (NZ) indicate increased community use, highlighting the need for closer scrutiny.
Aim:
This preliminary study aimed to assess the appropriateness and guideline compliance of cefalexin prescribing.
Methods:
We conducted a cross-sectional study reviewing all cefalexin prescriptions issued at a single urban medical centre in Ōtautahi Christchurch, NZ, during July-August 2023. Retrieved prescriptions were assessed for guideline compliance and clinical appropriateness using a modified audit survey based on national and regional guidelines.
Results:
We identified 27 cefalexin prescriptions provided to 25 patients (16 female, 20 NZ European; median age 48.9 years, IQR 49.7). Soft tissue (n = 11, 42.3%) and genito-urinary infections (n = 10, 38.5%) were the most common indications. Of the assessable prescriptions (n = 26), 14 (53.8%) were guideline compliant, and 15 (57.7%) were clinically appropriate. Indications were documented in 22 cases (84.6%) - 6 on the prescription and 19 in the clinical record.
Discussion:
This exploratory study identifies areas for targeted antimicrobial stewardship interventions in general practice to promote improved prescribing practices. A larger multicentre study is planned to further investigate prescribing patterns and appropriateness.
Insights
This study found that over half of cefalexin prescriptions in New Zealand were not fully guideline compliant or clinically appropriate. Interventions are needed to improve antimicrobial stewardship and cefalexin prescribing practices.
Area of Science:
- Pharmacology
- Infectious Diseases
- Public Health
Background:
- Antimicrobial resistance is a growing global threat driven by antibiotic misuse.
- Cephalexin is a second-line antibiotic, but its community use is increasing in New Zealand.
- This trend necessitates a closer examination of cefalexin prescribing patterns.
Purpose of the Study:
- To evaluate the appropriateness and guideline adherence of cefalexin prescriptions.
- To identify areas for improvement in antimicrobial stewardship.
Main Methods:
- A cross-sectional study was conducted at an urban medical center in Christchurch, NZ.
- Prescriptions from July-August 2023 were reviewed for guideline compliance and clinical appropriateness.
- A modified audit survey based on national and regional guidelines was utilized.
Main Results:
- 27 cefalexin prescriptions were analyzed.
- Soft tissue and genito-urinary infections were the most common indications.
- Only 53.8% of prescriptions were guideline compliant, and 57.7% were clinically appropriate.
Conclusions:
- The study highlights suboptimal cefalexin prescribing in primary care.
- Targeted antimicrobial stewardship interventions are recommended.
- A larger, multicenter study is planned for further investigation.
