However, this feedback to physicians and information campaigns could be better focused, as practitioners and patients are broadly targeted. Indeed, in the case of the United Kingdom, feedback practices focusing on physicians with the highest prescribing rates for antibiotics were effective in reducing their use, while patient-focused information campaigns had limited effects (OECD, 2017b). Hospitals represent around a quarter of overall pharmaceutical sales in France, and the share of generics use there was only 2.3% in value in 2013 (ANSM, 2014). This low share is partly explained by different patient pathologies and hospitals’ heavier and more innovative treatments (OECD, 2015b), but producers also often sell branded drugs at discounted prices to gain a wider market (Dahan, 2016).
