Risk factors for MRSA colonization, including:
|
CAP: community-acquired pneumonia; MRSA: methicillin-resistant Staphylococcus aureus; IV: intravenous; COPD: chronic obstructive pulmonary disease.
* The presence of these risk factors generally warrant empiric treatment in patients with CAP of any severity.
¶ The presence of these factors should raise suspicion for MRSA or Pseudomonas infection and generally warrants treatment in those who are severely ill; in others, the need for empiric treatment should take into account local prevalence, severity of illness, and overall clinical assessment.
Δ This factor is associated with community-acquired MRSA infection, which can cause severe toxin-mediated infection. Refer to the UpToDate topic on MRSA infections and treatment of CAP in patients with risk factors for MRSA infection for further detail.آیا می خواهید مدیلیب را به صفحه اصلی خود اضافه کنید؟
