Antibiotic use: how to improve it?

Antibiotics are an extremely important weapon in the fight against infections. However, antimicrobial resistance is a growing problem. That is why the appropriate use of antibiotics is of great importance. A proper analysis of factors influencing appropriate antibiotic use is at the heart of an effective improvement programme, as interventions can only result in improved medical behaviour if they are well attuned to the problems, the target group, and the setting in which the change is to take place. Determinants of appropriate and inappropriate prescribing are not only found in patient knowledge and behaviour, in the way medical professionals think and act, and in the way in which patient care is organised, but also in the wider, socio-cultural environment of doctors and their patients. We present several relevant factors at each of these 4 levels and various possible measures that could be an effective response to them. The reasons why antibiotic use is inappropriate are complex. This means that any programme to rationalise antibiotic use - if it is to be effective - will have to include activities at all 4 levels discussed above. A national programme for 'appropriate antibiotic use' could be considered, including patient, professional and organisational-oriented activities. In addition, close international cooperation is required involving international guidelines, agreements, monitoring and feedback of information, and implementation programmes.
