Wound Assessment and Management

Assessment Frequency and Healing Progress

• Wounds should be assessed at least daily with dressing changes to allow for proper inspection and evaluation of healing progress, as recommended by the American Diabetes Association 1
• Daily assessment is required for most wounds to monitor healing progress and detect complications early, with more frequent debridement associated with higher healing rates 1
• For wounds that are poorly perfused, deep, large, or necrotic, clinical re-evaluations should accompany treatment strategy 1

Infection Management and Re-evaluation

• Prompt and frequent assessment of foot infection with antibiotics and debridement is recommended, with repeated wound assessment during follow-up necessary to evaluate wound characteristics and identify signs of biofilm or infection 2, 3
• Infection severity should be defined using the IWGDF/IDSA infection classification and WIfI (Wound, Ischemia, foot Infection) classification, as recommended by the Infectious Diseases Society of America 4
• The following table outlines recommended antibiotics based on infection severity:

1, 3, 5

• Treat mild infection with oral antibiotics such as amoxicillin/clavulanate, dicloxacillin, clindamycin, or cephalexin for 1-2 weeks, as recommended by the Infectious Diseases Society of America 3, 1
• Treat moderate infection with oral or parenteral antibiotics based on the clinical situation, with options including amoxicillin/clavulanate, ceftriaxone, trimethoprim-sulfamethoxazole, or levofloxacin for 1-3 weeks, as recommended by the Infectious Diseases Society of America 3, 6, 1
• Treat severe infection with immediate hospitalization, aggressive surgical debridement, broad-spectrum intravenous antibiotics, and urgent vascular assessment with potential revascularization, as recommended by the Infectious Diseases Society of America 3, 6

Standardization of Wound Assessment and Management

• Inconsistent assessment, such as lack of standardized wound assessment, leads to poor outcomes, highlighting the importance of wound management guidelines, as recommended by the American Diabetes Association and the Infectious Diseases Society of America 3, 7, 8
• Choose dressings based on wound characteristics, such as using continuously moistened saline gauze or hydrogels for dry/necrotic wounds, alginates or foams for exudative wounds, and hydrogels or hydrocolloids for wounds requiring autolysis, as recommended by the Infectious Diseases Society of America 3, 6
• Avoid using topical antiseptic or antimicrobial dressings for wound healing of diabetes-related foot ulcers, as evidence does not support their use for promoting wound healing, according to the American Diabetes Association 7
• Avoid using honey or bee-related products for wound healing in diabetic foot ulcers, as advised by the Infectious Diseases Society of America 7
• Clean wounds regularly with water or saline to promote healing, and control exudate to maintain a moist wound environment, as recommended by the Clinical Infectious Diseases guidelines 9
• Select dressings based on exudate control, comfort, and cost, considering hydrogels for autolytic debridement and enzymatic debridement for sloughy wounds, as suggested by the Clinical Infectious Diseases guidelines and the American College of Cardiology 10, 2, 3

Vascular Assessment and Management

• Assess vascular status by checking peripheral pulses and consider non-invasive vascular studies, and consider revascularization if ischemic (toe pressure <30 mmHg), as recommended by the American College of Cardiology and the Diabetes/Metabolism Research and Reviews 2, 1, 11, 12
• Perform vascular imaging if toe pressure is less than 30 mmHg, TcPO2 is less than 25 mmHg, ankle pressure is less than 50 mmHg, or toe-brachial index is less than 0.5, as recommended by the American College of Cardiology and the Diabetes/Metabolism Research and Reviews 11, 12
• Revascularization is essential for wounds with underlying vascular insufficiency, as stated by the American College of Cardiology and the Infectious Diseases Society of America 13, 1

Multidisciplinary Care and Patient Education

• A coordinated approach is essential, involving vascular surgeons, infectious disease specialists, endocrinologists, podiatrists/foot surgeons, and wound care specialists, as recommended by the Infectious Diseases Society of America 4
• A coordinated care approach with a structured team composition, including wound care specialists, vascular surgeons, infectious disease specialists, endocrinologists, nutritionists, and physical therapists, is necessary for optimal wound care, as stated by the American College of Cardiology and the Infectious Diseases Society of America 13
• Optimizing diabetes management with target individualized HbA1c goals is recommended for patients with poor wound healing, as suggested by the American College of Cardiology 14
• Educate patients on signs of infection requiring prompt medical attention, and the importance of wound care compliance and follow-up, as recommended by the Clinical Infectious Diseases guidelines and the American Diabetes Association 6, 12
• Instruct patients on proper foot care, recognition of signs and symptoms of new or worsening infection, and prevention of contralateral foot ulcers, as recommended by the American Diabetes Association 12

Follow-up and Reassessment

• Reassess wounds frequently to evaluate healing progress, with follow-up within 2-3 days for infected wounds and 7-10 days for initially uninfected wounds, and monitor for signs of spreading infection or deterioration, as recommended by the American College of Cardiology and the Clinical Infectious Diseases guidelines 2, 6
• Delayed recognition and intervention can lead to severe diabetic foot infections escalating to limb and life-threatening conditions within hours, as stated by the Infectious Diseases Society of America 4
• Inappropriate antibiotic selection, such as using narrow-spectrum antibiotics for severe infections, can lead to poor outcomes, as recommended by the Infectious Diseases Society of America 6
• Delayed referral to multidisciplinary foot services can result in significant clinical deterioration, as stated by the Infectious Diseases Society of America 4
• Neglecting underlying conditions, such as vascular insufficiency, diabetes control, or nutritional status, will prevent healing, as recommended by the American College of Cardiology 2
