Antimicrobial Stewardship Implementation
In its broader holistic sense, antibiotic stewardship is the careful and responsible management of antibiotic resources in the interest of long-term sustainability.
There is general consensus that antibiotic resistance development and spread can be curtailed by limiting antibiotic use, discouraging misuse, and reducing the burden of infectious disease.1 An optimally functioning antimicrobial stewardship program is instrumental in accomplishing these goals. It can have significant positive impacts on morbidity and mortality, (Fig. 1) and potentially reduce healthcare costs in the range of 20-35%.2,3 Importantly, it plays a critical role in broad-based, larger scale efforts to help preserve our antibiotic resources for future generations.

Champions of Stewardship Programs
Numerous countries have championed national stewardship programs—with diverse strategies and varying degrees of success. Belgium's experiments in mass media campaigns resulted in a 36% decline in antibiotic prescriptions. This prompted France to initiate its own successful Antibiotics are not Automatic Anymore campaign, which is directed at the public and general practitioners, particularly in the implementation of rapid strep diagnostic tests for upper respiratory infections.
Other programs, e.g., Sweden's effective STRAMA initiative, the newly evolving Vietnam Resistance Program (VINARES), South Africa's Best care… Always! and the EU's ABS International, focus primarily on hospital-based stewardship efforts. In contrast, the Get Smart: Know When Antibiotics Work campaign in the U.S. is an example of an ongoing, multi-faceted approach that targets the general public, as well as healthcare facilities.5-10
