Abstract

Aim: To evaluate antimicrobial usage in the school-based clinics against operating guidelines.

Method: Antimicrobial prescribing data (2014) from 10/18 participating pharmacies serving 14,153/23,588 primary school children of the programme were accessible. Prescriptions from 5/10 pharmacies were available for identifying type, amount, and indication of the medicine. One pharmacy serving a defined population (n=3,513) with single healthcare provider delivering the school programme was selected for detailed evaluation and identifying individuals receiving multiple treatments.

Results: Data from 10 pharmacies (n=7,889 prescriptions) showed 91.2% of prescriptions were for group A streptococcal-positive throat swab, 8.8% for skin infections. More detail from 5/10 pharmacies showed only 2% of group A streptococcal pharyngitis treatments (107/4,672) were not first-line (56 cephalexin and 51 rifampin prescriptions). Fusidic acid (159/452, 35.18%) or cephalexin (169/452, 37.39%) were most commonly used for skin infection. Analysis in the defined population showed <4% (151/4,325) of assessed skin conditions received antimicrobials, and only 6 individuals received more than one course of oral antimicrobial over the year.

Conclusion: Antimicrobial administration demonstrates high compliance with the protocol. There was very limited use of second-line antimicrobials for recurrent pharyngitis. Most skin infections did not require antimicrobial treatment. Repeated antimicrobials for individuals were rare.
