Background: The aim of this cohort study was to assess the inter-observer agreement of three diabetic foot classification systems: the Wagner, the University of Texas and the PEDIS.
Methods: We included 250 consecutive patients diagnosed of diabetic foot syndrome in 2009-2013. Wound scores were recorded at admission and a reevaluation was performed simultaneously or 24h later by a different evaluator. Demographical, laboratory data and associated risk factors were obtained from the patients’ medical records.
Results: The Kappa coefficient showed a moderate inter-observer agreement between the first evaluation and the reevaluation for Wagner scale (Kappa=0.55; 95% CI: 0.507-0.593), University of Texas scale (Kappa=0.513; 95% CI: 0.463-0.563) and for PEDIS scale (Kappa=0.574; 95% CI: 0.522-0.626).
Conclusions: This moderate agreement shows that these scales should not be used alone for management decisions regarding diabetic foot syndrome and should, therefore, be integrated with other clinical data to ensure an adequate handover.
