    Current guidelines recommend prompt initiation of antimicrobial treatment after obtaining blood cultures in suspected infective endocarditis (IE).

  • 2

    This study assessed the impact of deferring antimicrobial treatment in clinically stable patients with suspected IE across two Swiss hospitals.

  • 3

    Among 1230 episodes, 30-day mortality was 5% with no significant difference between immediate and deferred treatment groups.

  • 4

    The composite primary endpoint of new embolic events or infections also showed no significant difference between immediate and deferred treatment.

  • 5

    Deferring antimicrobial treatment until blood culture results in clinically stable patients with suspected IE did not worsen clinical outcomes.
