AFSS: athlete's foot severity score. A proposal and validation

We developed a simple scoring system to evaluate the severity of tinea pedis (Athlete's foot severity score, AFSS). The AFSS consists of a clinical evaluation, using a three-point scale, of erythema and scaling in the plantar and interdigital spaces of the feet, and counts of interdigital spaces involved. Each foot is evaluated separately. The validity of the AFSS was assessed in 224 soldiers of the Israel Defense Force using mycological cultures as the main outcome measure and subjective assessment of pruritus as the secondary outcome measure. Mycological examinations were performed in 106 patients who had clinical evidence of tinea pedis. AFSS was significantly associated with culture results (P<0.0001), as well as with the presence of pruritus (P=0.002), and pruritus scores (P=0.025). We conclude the AFSS is valid for the clinical evaluation of tinea pedis severity in military settings. The application of AFSS to civilian morbidity should be subjected to further evaluation.
