CPD Article | EQUINE Focus on Antibiotic Stewardship – What’s Hot and What’s Not? Catriona Lyle BVM&S MSc CertEM(IntMed) DipECEIM [email protected] Antibiotic stewardship can be defined as a systematic approach to optimise appropriate use of antimicrobials in order to improve patient outcome and limit emergence of resistant pathogens. The SAEVA Antibiotic Use Policy is available on the SAEVA website to help guide appropriate antibiotic use - http://www.saeva.co.za/wp-content/uploads/2018/07/ Antibiotic-Use-Policy-edited.pdf This article is not intended as a fully comprehensive article on antibiotic stewardship but provides an update on some topical issues in antibiotic stewardship both in the context of one health and specific to equine practice. What’s Hot? 1. One Health While there is growing awareness of multi-drug resistant pathogens within equine practice it is also important to consider the impacts of antibiotic use not only on the patients they are prescribed for but on other animals, people and the environment. One Health can be defined as an integrative effort of multiple disciplines and multiple government sectors and partners working locally, nationally, and globally to attain optimal health for people, animals, and the environment. SAEVA is represented in The South African Antibiotic Stewardship Programme (SAASP) which is engaging with stakeholders involved in human, animal and environmental health. 2. Being AWaRe The 2017 revision of the World Health Organisation’s (WHO) Essential Medicines List classified antibiotics into 3 categories (Access, WAtch and REserve) with the aims of improving access and clinical outcomes, reducing development of antibiotic resistance and preserving effectiveness of “last-resort” antibiotics. Access antibiotics are first-choice and second- choice antibiotics that are generally narrow-spectrum with lower resistance potential. WAtch antibiotics are broader-spectrum and therefore have greater resistance potential. A small number of antibiotics from the Watch group were also recommended for first- or second-line treatment for a few specific conditions in humans. REserve antibiotics should be treated as last- resort options i.e. used when alternatives have failed or cannot be used.
