Overview
This section provides a short and straight to the point overview of the disease or symptom. The first sentence of the overview must contain the name of the disease.
Causes
Life Threatening Causes
Life-threatening causes include conditions that may result in death or permanent disability within 24 hours if left untreated. Diabetic foot superseded with the following may result in sepsis and death.
- Infected diabetic foot
- Osteomyelitis
Common Causes
- Poor glycemic control
- Peripheral neuropathy
- Peripheral arterial disease
- Peripheral ischemia
- Improper footwear
- Foot deformities including Charcot arthropathy
Diagnosis
Assessment of diabetic foot includes evaluation of peripheral arterial disease, peripheral neuropathy, and foot deformities. Shown below is an algorithm summarizing the diagnosis of diabetic foot and diabetic foot ulcers according to the recommendations of the American Diabetes Association and International Diabetes Federation- Clinical Practice Recommendations on the Diabetic Foot 2017. "Guidelines". [1]
Characterize the symptoms: ❑ Onset ❑ Type of sensation ❑ Location ❑ Nocturnal variation ❑ Aggravating factors ❑ Relieving factors Obtain a detailed history: ❑ Onset of diabetes ❑ Duration of diabetes ❑ Compliance with medication ❑ History of glycemic control ❑ History of other diabetic complcatios ❑ Foot deformities/injuries/ulcers ❑ History of lower limb amputation ❑ Type of footwear ❑ Foot hygiene ❑ History of claudication ❑ Smoking history | |||||||||||||
Examine the patient: Inspection ❑ Location of ulcer ❑ Integrity and charcteristic (dry/cracked) of skin ❑ Sweating Palpation ❑ Pedal (dorsalis pedis) pulses ❑ Vibration sensation ❑ Ulcer site- warmth, tenderness, edema Non-invasive tests ❑ Semmes-Weinstein monofilament test ❑ Probe-to-bone test if suspected osteomyelitis ❑ Measure ABI (Ankle-Brachial Index) with a Arterial doppler | |||||||||||||
Order tests: ❑ Glycosylated hemoglobin/ HbA1c ❑ Fasting plasma glucose ❑ Complete blood count ❑ ESR and CRP ❑ Deep tissue specimen for culture | |||||||||||||
Treatment
Assessment of diabetic foot includes evaluation of peripheral arterial disease, peripheral neuropathy, and foot deformities. Shown below is an algorithm summarizing the diagnosis of diabetic foot and diabetic foot ulcers according to the recommendations of the American Diabetes Association and International Diabetes Federation- Clinical Practice Recommendations on the Diabetic Foot 2017. "Guidelines". [2] [3] [1]
Adapted from Diabetes Care. 2013;36(9):2862-71. and Clin Infect Dis. 2012;54(12):e132-73.
Prophylactic measures and Diabetic foot care in all patients ❑ Glycemic control ❑ Apporpriate footwear and podiatric care • ❑ Mechanical offloading • Cast Walkers • Total contact casting • Therapeutic shoes ❑ Vascular care to prevent and treat peripheral arterial disease | |||||||||||||||||||||||||||||||||||||||||||
❑ Local wound care ❑ Debridement | |||||||||||||||||||||||||||||||||||||||||||
Peripheral arterial disease or signs of ischemia | Medication/Surgical or endovascular revascularization | ||||||||||||||||||||||||||||||||||||||||||
Presence of infection | • Mechanical or chemical wound debridement • Culture • Biopsy | ||||||||||||||||||||||||||||||||||||||||||
• Assess severity of infection according to the table below • Treat with antiobiotics according to the table below | |||||||||||||||||||||||||||||||||||||||||||
If infection does not resolve within 30 days- • Consider hyperbaric oxygen therapy | |||||||||||||||||||||||||||||||||||||||||||
• Observe foot • Establish regular care • Reassess in 2-3 months | |||||||||||||||||||||||||||||||||||||||||||
- DFI is classified based on its severity according to the Infectious Diseases Society of America (IDSA) guideline or the PEDIS grade developed by International Working Group on the Diabetic Foot (IWGDF). (see Table below)
- Selection of empiric antimicrobial regimen should be determined by the severity of DFI and the likely etiologic agents.
|
- 5. What is the appropriate route, setting, and duration of antibiotic therapy?
- The table below describes the recommended route, setting, and duration of antibiotic therapy based on the extent and severity of DFI.
|
Empiric Therapy
▸ Click on the following categories to expand treatment regimens.
Uninfected (Grade 1) ▸ No Evidence of Infection Mild (Grade 2) ▸ Acute Infection Without Recent Antibiotic Use ▸ High Risk for MRSA
Moderate to Severe (Grade 3–4) ▸ Chronic Infection or Recent Antibiotic Use ▸ High Risk for MRSA ▸ High Risk for Pseudomonas aureuginosa ▸ Polymicrobial Infection |
|
Do's
- Check for signs of ischemia.
- Check for signs of infection.
- Always get a wound culture to determine the type of organism and choice of antibiotic.
- Prophylactic podiatric care.
- Mechanical offloading in all patients. [2]
Don'ts
- Don't treat the ulcer without treating the underlying infection, ischemia, and appropriate glycemic control.
