Overview

Community acquired pneumonia should be distinguished from healthcare-associated pneumonia as these diseases have different causative organism, prognosis, diagnostic and treatment guidelines.

Diagnostic Criteria

Community-Acquired pneumonia

Patient who has not been hospitalized or in an institutional setting for the past 2 weeks and have the following findings:

  • CXR findings of a new infiltrate. Although there is no gold standard for the diagnosis of community acquired pneumonia (CAP), a new infiltrate on chest radiograph in the setting of acute respiratory complaints (e.g., cough and dyspnea) is considered highly suggestive of CAP.
  • At least 2 of the four need to be present. The four symptoms are fever, cough, dyspnea, chest pain.

Hospital Acquired Pneumonia

According to the Infectious Diseases Society of America and the American Thoracic Society healthcare-associated pneumonia includes any patient who meet the below criteria [1]

  • Hospitalized in an acute care hospital for 2 or more days within 90 days of the infection;
  • Resided in a nursing home or long-term care facility;
  • Received recent intravenous antibiotic therapy, chemotherapy, or wound care within the past 30 days of the current infection;
  • Attended a hospital or hemodialysis clinic.
