    Staphylococcus aureus is a major cause of pneumonia in critically ill ICU patients, complicating treatment due to methicillin resistance.

  • 2

    De-escalation of antibiotic therapy from broad-spectrum to β-lactam is recommended for patients with methicillin-susceptible Staphylococcus aureus pneumonia.

  • 3

    Studies indicate that de-escalation practices lead to shorter ICU stays and lower hospitalization costs without increasing mortality rates.

  • 4

    Antimicrobial stewardship, including de-escalation strategies, is essential in minimizing antibiotic resistance in ICU settings.

  • 5

    This multicenter study aims to evaluate clinical outcomes of de-escalated versus standard antibiotic therapy for MSSA pneumonia in critically ill patients.
