WHAT’S NEW
Clinical support for 2007 guidelines
This is the first study to clinically support the IDSA/ATS guidelines, which state that a 5-day course of antibiotic therapy for hospitalized adults with CAP is effective and without increased risk of adverse events.
CAVEATS
Generalizability to other meds and settings is unclear
This study focused on antibiotic duration for the treatment of CAP in hospitalized patients and mainly used quinolone antibiotics. It remains unclear if duration of therapy is as effective in the outpatient setting or when using alternative antibiotic regimens.
If patients continued to have symptoms (such as fever or low oxygen saturation on room air) after 5 days of antibiotic treatment, antibiotic treatment was continued in the study. Thus, patients in real life who continue to have symptoms may need individualized therapy and may require more than 5 days of antibiotics.
CHALLENGES TO IMPLEMENTATION
Antibiotics end before clinical improvement occurs
This study noted an average of 12 days in both groups for patients to achieve clinical improvement, with upwards of 15 to 18 days for patients to return to normal activity. Patients and providers may be dissatisfied if the treatment course ends days before clinical improvement of symptoms. This may cause prescribers to lengthen the duration of antibiotic therapy inappropriately.
