The urgency to close DFU’s • 10 year prospective study of patients over 65, a neuropathic ulcer was predictive for a 45% mortality rate over 5 years.1 • Three most common factors leading to limb amputation: • Gangrene, infection, non-healing wound4 • Iversen, Tell, Riise, et al 2009 • Rogers, L. 2010
Standard Treatment Fails to Heal DFU’s Standard treatment: • Wound Bed preparation: Debridement • Infection Control • Revascularization • Off Loading Only 25% of patients who received this standard treatment healed by 16 weeks.5,6 5. Steed and colleagues J AM CollSurg 1996 Multicenter randomized 6. Margolis and colleagues, Diabetes Care 1992 Meta-analysis
A systematic review of literature revealed that between 30% - 40% of patients were not being treated according to current evidence.2 • A 2010 consensus panel identified that 20-30% of the care provided was inappropriate or dangerous.3 • Schuster and colleagues • Snyder, Kirsner and colleagues 2010 Consensus Report
Evidence Based DFU Treatment Guidelines abound Association for the Advancement of Wound Care American College of Foot and Ankle Surgeons American Diabetes Association American Orthopedic Foot and Ankle Society Wound Ostomy Continence Nurses Society Wound Healing Society
Guidlelines • Provide a standard framework for assessment and diagnosis. • Establish best practice standards for basic wound care interventions and expected progress. • Provide guidance for evidence based use of advanced wound therapies. • Provide a reference from which to measure outcomes.
Medical Management Glucose Control: HbA1c. <7%. Neurologic Testing: Monofilament 5.07 Vascular Assessment Edema Management: Elevation vs. compression Nutrition: Diabetic education, Pre-albumin Social barriers: Living situation, lack of family support, financial Patient beliefs and motivation: Motivational interviewing8 8. CARL J. POSSIDENTE, and colleagues Am J Health-Syst Pharm. 2005
Wound Assessment Measure the wound: Length x width x depth Consistency is key to tracking progress Probe to Bone Controversy8,9 Use appropriate size probe for the wound Can identify underlying foci of indolent infection in otherwise healthy appearing wound Wound tissue and Infection Healthy tissue is pink with advancing, adherent edge. Friable, dark tissue with undermined edges is not. 8.Lavery, et al Diabetes Care 2007 9. Grayson and colleagues, JAMA 1995
Basic Standard Wound Care Off load : If the offloading device can be removed it will be Caution in use of wheel chairs and crutches9 Debridement Reduces bacterial bioburden, reduces infection Converts wound to an active, proliferative state. Suggested weekly and as needed5 Surgical and Sharp recommended. Enzyme: Santyl the only one still on market. Manage /Rule Out Infection Provide Moist Wound healing 9. Orsted and colleagues, WoundCare 2007 5. Steed and Colleagues Regranex study, numerous other studies
Basic Standard Wound Care: Moist Wound Healing Goals: Maintain a moist wound surface Minimizes trauma to the wound tissue Minimize risk of infection Manage drainage to preserve peri-wound skin. 50% Reduction in wound size at 4 weeks Dressing selection should be based on choosing the most cost effective dressing which meets wound needs9 • Orsted and colleagues, WoundCare 2007
Basic Standard Wound Care: Moist Wound Healing Cleanse with noncytotoxic cleansers10 Saline, clean water, wound cleansers, surfactants Wound gels and pastes: Amorphous wound gel, Cadexomer Iodine wound paste, Manuka honey Wound Fillers: Gauze, Calcium alginate, collagen Cover dressings: Gauze, foam , hydrocolloids, composite dressings, film dressing, silver impregnated dressings 10. WOCN guideline2004
Home or Skilled Care Wound Supplies • Most Insurers cover primary and secondary dressings. • Coverage requires a complete prescription • Wound dimensions, date of assessment, supplies and frequency of change. • Limit number of dressing prescribed to accommodate for revised dressing needs as the wound changes. • Nursing Facilities and Home Health organizations are on strict formularies and need wound care orders written in generic terms. i.e. • Adhesive foam dressing vs. propriatary Allevyn, Hydrasorb , Polymem • Hydrocolloid • Calcium alginate
Reassess wounds regularly • Frequency based on needs of the wound and the patient. • Failure to achieve 50% reduction in size over 4 weeks indicates need to reevaluate; • Patient comorbidities • Offloading • Adequacy of debridement and wound care If goals have been met in these areas consider use of advanced wound therapies. 3,13,14, 3. Snyder, Kirsner, et al, 13. Bolton, et al N Engl J Med. 2004 14.Sheehan and colleagues, Diabetes Care 2003
Advanced Wound Therapies It is the basic care which prepares the wound for advanced therapies. Skip the basics and it will not make a difference what advanced therapies you use.7 • Frykberg, Wounds 2010
Advanced Therapies Negative Pressure Therapy Kalypto, Svedman, Renasys, VAC Manage drainage, enhance wound contraction and angiogenasis Extracellular Matrix products Oasis, Integra, GRAFTJACKET regenerative tissue matrix, Provide a scaffold for tissue in growth and cellular migration Cellular Based Tissue Technologies Apligraf, Dermagraftt. Both have FDA approval15, 16 Provide growth factors to the wound to stimulate healing Hyperbarics
Other Advanced Therapies • Platelet Rich Plasma • Ultrasonic spray (MIST, Celleration) • Electrical stimulation • Super oxidized water ( Dermacyn)
Advanced Wound Therapies By using a combination of these advanced therapeutic products based on their supporting clinical science and evidence we should be able to improve DFU healing. Advanced Therapies of course come at an advanced cost. A number have a favorable reimbursement which drives use. Remember Bercaplamin….
The Reality of Diabetic Ulcer Healing At the end you get back: A diabetic patient, With a Neuropathic foot, Who has a very expensive layer of skin over scar tissue. So what comes next?
Managing ComorbiditiesLifestyle/Psychosocial Factors Patient Compliance • Patient Centered Plan of Care • The wound belongs to the patient and he must be an active participant in the plan to heal it. • Motivational interviewing/Motivational Enhancement • Discovering the barriers the patient perceives and assisting him to discover his own solutions may result in improved compliance.
