Background
� Threats of MDR organisms and public health emergencies have exposed the need for more robust antimicrobial stewardship and for collaboration in the emergency preparedness.
� There is a need for coordinated efforts to effectively manage this «new deal».
� However, financial pressures are likely to compete with the expanding roles and expectations of physician-epidemiologists in IPC.
What is antimicrobial stewardship?
• A strategy, a coherent set of actions designed to use antimicrobial responsibly.
• Responsible use: it should be defined and translated into context- and time-specific actions

Respondents’ Opinion
In March 2012, a 55-question online survey was e-mailed to 94 physicians or pharmacists in acute care hospitals in the United States. Response rate was around 52%.

Strategies for controlling transmission of multidrug-resistant (MDR) pathogens in the intensive
care unit (ICU)
• Reduce selection pressures
– Improved antimicrobial (including disinfectants?) stewardship
– Ensure balancing measures are also considered
• Prevent spread (targeted or vertical strategies)
– Screening strategies
– Improve infection control e.g. hand hygiene, isolation measures
• Consider decolonisation (Horizontal strategies)
Reducing the reservoir and perhaps increasing colonisation resistance?

•Contact precautions and antimicrobial stewardship are effective in preventing nosocomial MRSA infections.
•Before-after study� implementation of a bundle approach consisting of MRSA active surveillance, contact precautions for MRSA positive patients, and CFZ based AMP stewardship

• Review of 31 studies� 7 RCTs, before/after
controlled studies or before/after uncontrolled styudies with interrupted-time-series analysis.
• IDS intervention was associated with a significant improvemente on the appropriateness of antibiotic prescribing as compared with prescriptions without any IDS input.
