The project will also create reusable evaluation tools transferable across environments. Through a combination of observation and interviews, investigators will examine librarian involvement in three existing Vanderbilt CICS intensive care units. The project will collect detailed information about the ways in which clinicians incorporate CICS-provided information into their workflows. Next, investigators will conduct a randomized trial to evaluate the effect of CICS on decision-making. Investigators will compare clinicians' intended course of care vs. actual care when CICS results are provided and when clinicians seek information themselves.
