Impact of regular collaboration between infectious diseases and critical care practitioners on antimicrobial utilization and patient outcome.

Objective: Antimicrobial stewardship programs have been shown to help reduce the use of unnecessary antimicrobial agents in the hospital setting. To date, there has been very little data focusing on high-use areas, such as the medical ICU. A prospective intervention was done to assess guideline compliance, antimicrobial expenditure, and healthcare cost when an infectious disease fellow interacts regularly with the medical ICU team.
