Li et al reported the CCERW score for evaluating an adult with community-acquired pneumonia (CAP). This can help to identify a patient who may benefit from more aggressive management. The authors are from Henan College of Traditional Chinese Medicine in China.
Patient selection: community-acquired pneumonia and >= 45 years of age
Parameters:
(1) confusion (C)
(2) serum creatinine (C)
(3) electrolyte disturbance involving sodium or potassium (E)
(4) respiratory failure (R)
(5) white blood cell count (W)

total score =
= SUM(points for all 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: 6
• The higher the score the greater the risk of treatment failure.
