Reducing inappropriate prescribing of antibiotics in English primary care: evidence and outlook.

Antibiotics are indispensable for treating bacterial infections, but their effectiveness is threatened by the emergence and spread of antibacterial resistance. Antibiotics are unique among drugs since the more they are used, the less effective they become because bacterial resistance is likely to develop. In response to this threat, the UK government aims to reduce inappropriate antibiotic prescribing in humans by 50% by 2020. A team at Public Health England has found that at least 20% of antibiotic prescriptions in primary care in England were inappropriate, which, if correct, implies that antibiotic prescribing nationally needs to be reduced by 10% by 2020. These data are published in five articles in a Supplement to JAC entitled Appropriateness of antibiotic prescribing in English primary care. Inappropriate prescribing was found in every general practice included in the analyses so each one should attempt to reduce unnecessary prescriptions, not just high-prescribing practices. An ambition of 10% reduction in antibiotic prescriptions seems attainable when compared with the reduction targets of other European countries. The need for substantial improvements in data quality that are necessary to further safeguard this precious resource is also highlighted by the authors in this Supplement.
