How do you prescribe antibiotic in icu?

In the ICU, antibiotic prescribing involves a careful assessment of the patient's clinical condition, identification of the likely pathogens, and consideration of local antibiotic resistance patterns. Empirical therapy is often initiated based on common infections, tailored later with culture results when available. Dosages and duration should be adjusted for renal or hepatic function, and ongoing monitoring is essential to evaluate treatment response and make necessary modifications. Multidisciplinary collaboration with infectious disease specialists can enhance the effectiveness and appropriateness of antibiotic therapy.
