Objective:

To evaluate the outcomes of shorter antibiotic courses compared to longer courses in hospitalized patients with community-acquired pneumonia who are clinically stable by day 3.

Approach:
    Key Findings:
    • Mortality was less than 1% in both short- and longer-duration groups.
    • Readmission rates were about 8% to 9% within 30 days.
    • Urgent health care visits and Clostridioides difficile infections occurred at similar rates.
    • Antibiotic-associated adverse events were uncommon and similar between groups.
    Interpretation:

    Findings apply to clinically stable patients hospitalized with community-acquired pneumonia, but only about 10% met eligibility criteria, limiting generalizability.

    Limitations:
    • Few patients received short-course therapy.
    • Residual confounding may have influenced results.
    • Low event rates limited precision.
    • Follow-up was limited to 30 days.
    Conclusion:

    Shorter antibiotic courses were associated with similar outcomes compared to longer courses in clinically stable patients, supporting guidelines for shorter treatment durations.
