Knowledge

Students should be able to define and describe:

  • the difference between bronchitis and pneumonia
  • differentiate acute from chronic pneumonia.
  • the spectrum of organisms responsible for the clinical presentation of lower respiratory tract infection in community-acquired, nosocomial, or aspiration pneumonia and respiratory infections in the immunocompromised host.
  • patients who are at risk for impaired immunity.
  • the complications of acute bacterial pneumonia including:
    • bacteremia
    • sepsis
    • empyema
    • meningitis
    • metastatic microabscesses
  • the antimicrobial susceptibility patterns of s. pneumoniae
  • the rationale for antibiotic selection in different patient populations and the appropriate duration of therapy
  • the role of intravenous versus oral antibiotics in the management of community acquired pneumonia
  • the pharmacokinetics of commonly prescribed antibiotics
  • the role of pneumococcal vaccine and influenza vaccine

Skills

Students should demonstrate specific skills, including:

  • History-Taking Skills: Students should be able to obtain, document, and present an a medical history that differentiates among the etiologies of lower respiratory infection.
  • Physical Exam Skills: Students should be able to perform an appropriate physical exam to establish the diagnosis and severity of disease, including:
    • determining respiratory rate and level of distress.
    • recognizing rales, rhonchi and wheezes.
    • recognizing signs of pulmonary consolidation, parenchymal collapse and pleural effusion.
    • recognizing signs of pneumonia complications listed above.
  • Laboratory Interpretation: Students should be able to interpret:
    • a chest x-ray
    • gram stain and acid-fast stain of sputum
    • pleural fluid cell count, gram stain and chemistries
    • arterial blood gases
  • Students should be able to define the indications for and interpret (with consultation) the significance of the results of:
    • sputum culture and sensitivities and sputum cytology
 
  • Communication Skills: Students should be able to:
    • explain the results of the evaluation, treatment plan and prognosis of the disease to patients and their families.
    • educate about pneumococcal and influenza immunizations

  • Management Skills: Students should be able to:
    • select an appropriate empiric antibiotic regimen for community-acquired, nosocomial, immunosuppressed-host, and aspiration-pattern pneumonia.
