Overview

Diabetic foot is classified according to its severity and factors such as the requirement of oral or parenteral antibiotics, outpatient management or hospitalization, and surgical intervention.

Diabetic foot infections are classified according to the severity of involvement to assist with clinical decision-making regarding the need for oral or parenteral antibiotics, outpatient management or hospitalization, and surgical intervention. The Infectious Disease Society of America (IDSA) introduced a classification scheme for these infections in their 2004 guidelines, broadly categorized as mild, moderate, and severe infections based upon the extent of infection and inflammation.^[1]

The International Working Group on the Diabetic Foot (IWGDF) published a similar classification system in 2012.^[2]
The aforementioned systems were externally validated in a longitudinal study to assess prognostic value, which demonstrated increased risk for amputation among patients with infections classified as severe.^[3]

Clinical Manifestation	PEDIS Grade	IDSA Severity
No symptoms or signs of infection	1	Uninfected
Local infection involving only the skin and the subcutaneous tissue without involvement of deeper tissues and without signs of SIRS If erythema, must be >0.5 cm to ≤2 cm around the ulcer. Exclude other causes of an inflammatory response of the skin (eg, trauma, gout, acute charcot neuro-osteoarthropathy, fracture, thrombosis, venous stasis).	2	Mild
Local infection with erythema >2 cm or involving structures deeper than skin and subcutaneous tissues (eg, abscess, osteomyelitis, septic arthritis, fasciitis) without signs of SIRS	3	Moderate
Local infection with the signs of SIRS, as manifested by ≥2 of the following: Temperature >38 °C or <36 °C Heart rate >90 beats/min Respiratory rate >20 breaths/min or PaCO2 <32 mm Hg White blood cell count >12,000 or <4,000 cells/μL or ≥10% immature (band) forms	4	Severe
