Prospective Study of the Wilson Severity-of-Illness Scoring System for Complicated Skin and Skin Structure Infections

ABSTRACT Wilson et al. (Am. J. Surg. 185: 369–375, 2003) developed a disease severity classification system for use in complicated skin and skin structure infections (cSSSI). Two phase 3 trials of ceftaroline fosamil in cSSSI provided the opportunity to evaluate the association between Wilson Severity Risk Class and clinical cure rates. Our analyses did not confirm that an association exists between Wilson Severity Risk Class and clinical cure rate and, thus, did not validate its predictive utility.
