Objectives:
• Review appropriate ulceration work up
• Become familiar with the IDSA guidelines for diagnosis/treatment of diabetic foot infections
• Understand treatment approaches for open ulcerations
Wound Evaluation
• Location– Bony prominence, proximal vs distal
• Size– Dimensions, depth, shape
• Tunneling/Undermining– Sinus tracts
• Bed– Granular/fibrotic/necrotic– Exposed tendon or bone
• Edges– Definition
Etiology of Ulcerations
• P‐ Pressure
• I‐ Infection (SSSI vs osteomyelitis)
• C‐ Circulation (vascular disease)
• S‐ Swelling
Rogers, LC. Diabetic Foot Ulcers: A Clinical Practice Pathway. 2016
Infection
• 5 cardinal signs of infection– Rubor‐ redness
– Calor‐ heat
– Dolor‐ pain
– Tumor‐ swelling
– Functio laesa‐ loss of function
– Also consider in cases of abscess:• Fluctuance
• Crepitus
• Radiographic signs of gas/fluid/air
Lipinski BA., et al. 2012 Infections Disease Society of America Clinical Practice Guideline for the Diagnosis and Treatment of Diabetic Foot Infections. Clinical Infectious Diseases: 54(12); 132‐173. 2102
Infection
• Other findings not indicative of wound infection:
– Drainage
– Smell
• Osteomyelitis
Initial Evaluation
Infection
• Decide whether or not
infection is present
– Manage infection if
present

IDSA Guidelines
• In which diabetic patients with a foot wound should I suspect infection, and how should I classify it?
1: Consider possibility in any DFU
‐ looking for redness, warmth, swelling, pain
2: Be aware of factors that increase risk
‐ + PTB, >30 days, recurrent wounds, traumatic wounds, PVD, Renal disease, or barefoot walking
IDSA Guidelines
• How should I assess a diabetic patient presenting with a foot infection
4: 3 levels‐ whole, foot/limb, wound
5: Diagnose based on at least 2 classic symptoms
IDSA Guidelines
• When and how should I obtain specimen for culture from a patient with a diabetic foot infection?
16: For uninfected wounds, DO NOT CULTURE
17: Send specimen prior to starting ABX
18: Send specimen, not swab
‐ After irrigation/debridement
IDSA Guidelines
• How should I select ABX?
19: Uninfected wound should NOT be treated with ABX
20: Infected wounds should be started on ABX, need to be in conjunction with appropriate wound care
21: Empiric therapy based on severity
22: Definitive therapy based on cultures
23‐24: Length based on severity
IDSA Guidelines
• When should I consider imaging studies, and which should I select?
25: Plain film x‐rays for all DFU
26: MRI only I abscess questionable or to R/O OM
27: IF no MRI, consider bone scan
Rogers, LC. Diabetic Foot Ulcers: A Clinical Practice Pathway. 2016
Circulation/Vascular
• Palpate pedal pulses
• CFT
• Doppler
• Consider NIVS even in the presence of palpable pedal pulses if the wound is not progressing as expected
• Referral for revascularization

Circulation/Vascular
– Pulses
• Popiteal
• posterior tibial
• dorsalis pedis
Circulation/Vascular
– Capillary Refill
– Digital Hair Growth
Rogers, LC. Diabetic Foot Ulcers: A Clinical Practice Pathway. 2016
Pressure‐ offloading
• Difficult and individualized
• Most effective is Total Contact Cast or Other Non‐removeable device
• Numerous other options exist– NWB
– AFO
– Custom shoes/orthotics
– Diabetic shoes

Treatment of DFU‐ Debridement
• Sharp debridement of open ulcerations removes fibrotic tissue and bacteria, stimulates angiogenesis, and turns a chronic wound into an acute wound
Myers, BA. The Wound Care Practitioner: Guidelines for Clinical Practice. Taken from: Wound Management: Principals and Practice, Third edition. Pearson 2012
Dressings
• Moist wounds heal 3‐5 times faster than dry wounds
• Divided into two basic types:– Primary dressing
• Dressing that comes into contact with the wound, sometimes called the contact layer
– Secondary dressing• Placed over the primary
dressing• Provides increased protection,
cushioning, absorption, or occlusion
• Functions of dressings:– Create moist wound
environment• Absorb excess exudate• Donate moisture to the wound
– Provide thermal insulation (37‐38 degrees C)
– Provide barrier to microorganisms
– Protect exposed nerve endings
– Hemostasis– Edema control– Elimination of dead space
Myers, BA. The Wound Care Practitioner: Guidelines for Clinical Practice. Taken from: Wound Management: Principals and Practice, Third edition. Pearson 2012
Dressings
• Continuum of dressings
– Gauze
– Impregnated Gauze
– Semipermeable Film
– Hydrogel
– Semipermeable Foam
– Hydrocolloid
– Alginate
Dressings
• Gauze:
– Example: Kerlix, Kling, Nu‐Gauze
– Benefits: Cheap, readily available
– Limitations: Adhere to wound bed, non‐selective debridement, higher infection rate
Dressings
• Impregnated Gauze:
– Example: Xeroform, adaptic
– Benefits: Decrease trauma, decrease pain
– Limitations: more costly, require secondary dressing
Dressings
• Semipermeable Film:
– Example: Tegaderm
– Benefits: Moisture retentive, allow visualization, encourage autolytic debridement
– Limitations: Adhesive, limited on amount of drainage, can not be used on infected wounds
Dressings
• Hydrogel:
– Example: SAF‐GEL, Solosite, AQUASORB
– Benefits: Moisture retentive, encourage autolytic debridement, reduce pain, inexpensive
– Limitations: may dehydrate, can not be used on highly exudative wounds, require secondary dressing
Dressings
• Semipermeable Foam:
– Example: Mepilex
– Benefits: Moisture retentive, encourage autolytic debridement, thermal insulation, protection
– Limitations: Adhesive, may roll, expensive
Dressings
• Hydrocolloid:
– Example: Aqua‐cell, Duo‐derm
– Benefits: Absorb drainage, able to be packed into tunneling wounds
– Limitations: Leave residue in wound, may cause hypergranulation, expensive
Dressings
• Alginate:
– Example: CURASORB
– Benefits: Absorbent, used on infected wounds
– Limitations: Requires secondary dressing, care must be taken on exposed tendon/bone
