The CICS is a well-established program that facilitates evidence-based practice by delivering targeted information in answer to complex, patient-specific questions. The CICS places librarians with specialized training in medical subject areas and in information retrieval ("clinical informationists") on clinical teams in intensive care settings. Acting as expert consultants, they analyze the biomedical literature to identify, filter, and present the best examples of each clinical viewpoint expressed about key problems.
