The document discusses the clinical effect of having a pharmacist as part of the medical team in an ICU setting. It recommends that pharmacists provide liaison services between pharmacy and medical staff, review medication regimens and antibiotic therapy, provide pharmaceutical data collection and evaluation, assist with protocols for antimicrobial prophylaxis and infectious disease therapy, assess risks and report adverse drug reactions, manage changes to medications in the post-operative period, provide drug and medical device information and monitoring, and assist with toxicology emergencies.
