Treatment and study plan

Primary outcomes

  1. mortality

    Time frame: From diagnosis of pneumonia to discharge from hospital or up to 90 days, whichever came first

    Mortality is defined the patient died in hospital.

Secondary outcomes

  1. severe pneumonia

    Time frame: From diagnosis of pneumonia to discharge from hospital or up to 90 days, whichever came first

    The pneumonia deteriorated and reached the criteria of severe pneumonia. Severe pneumonia was diagnosed according to the guideline published by ATS.

  2. initial treatment failure

    Time frame: From diagnosis of pneumonia to discharge from hospital or up to 90 days, whichever came first

    Initial treatment failure means the patients' condition progressively deteriorated although comprehensive treatment was administrated. As a result, the treatment should be changed or the patient required admission to ICU.
