The Centor score is an appropriate screening method for acute tonsillitis but limited to patients of at least 15 years of age. The Centor score uses 4 signs and symptoms and a scale of 0 to 4 for diagnosis.
Both the sensitivity and specificity of this prediction rule are 75%, compared with throat cultures. Antibiotics are advised if the Centor score is 3 or above.
Using the subclavian site for central venous catheterization reduced infections and DVT to a minimum, but tripled the risk of pneumothorax compared to the internal jugular (IJ) position. Using the femoral position eliminated pneumothorax risk, and was comparable to the IJ in infection risk, but significantly increased DVT risk.
