  1. Nutritional Considerations in Wound Healing Ronni Chernoff, PhD, RD

  2. Weight changes (losses or gains) may be related to a variety of risk factors

  3. Weight should remain stable during healing

  4. Immobilization and deconditioning are major factors in negative nitrogen balance

  5. To avoid or heal wounds of any type, nutrient needs must be met to support homeostasis

  6. However, nutrient requirements may change with age due to physiological, health status, body composition, and activity level changes

  7. Key nutrients needed for wound healing • Protein • Energy • Vitamin A • Vitamin C • Zinc

  8. Protein requirements are affected by: • decrease in total LBM • loss of efficiency in protein turnover • increased need to heal wounds, surgical incisions, repair ulcers, make new bone • infection • immobilization

  9. Protein requirements for older adults is 1 g/kg body weight

  10. Protein is necessary to make new tissue, fight infection, heal fractures

  11. Protein needs may be as high as 2+ g/kg body weight

  12. Energy needs increase with demands for wound healing, fracture repair, infection response

  13. To maintain weight, 20-25 kcals/kg body weight is usually adequate in a relatively sedentary adult

  14. For stress, wound healing, infection, fracture, energy needs may increase to as much as 35 kcals/kg body weight

  15. Vitamin A is needed for cell differentiation

  16. Vitamin A requirements in wound healing should not exceed 200% of the RDA

  17. Vitamin C • Status is related to dietary intake • Institutionalization, hospitalization and illness lead to sharp decreases in vitamin C intake

  18. Vitamin C • Decreases seen with chronic disease including atherosclerosis, cancer, senile cataracts, lung diseases, cognition, and organ degenerative diseases

  19. Vitamin C • Vitamin C is easily replaced • Smokers may need 2x RDA just to meet requirements

  20. Vitamin C • Vitamin C is important in wound healing because of its role in hydroxylation but tissue saturation is achieved easily and large doses are excreted in urine

  21. Zinc • Most older adults are not zinc deficient • Increased levels may be needed for wound healing but do not have to be very high (225mg/day in divided doses) • Large amounts of zinc interfere with absorption of other divalent ions

  22. Copper, iron, magnesium, manganese may be affected by large doses of zinc

  23. Meeting fluid requirements is often an issue in wound healing protocols

  24. Fluid intake can be estimated at 30 ml/kg body weight with a minimum of 1500 ml/day

  25. Sometimes pressure ulcers are unavoidable but optimal healing includes a nutrient dense diet that addresses the nutrient needs described

  26. Pressure Ulcer Management: Quick Tips Molly Brethour RN, CWOCN CAVHS Little Rock, Arkansas

  27. Wound Priorities Cause Cause Cause Establish goal Systemic factors Environmental modifications Then Optimize wound

  28. Determine Cause

  29. Unexpected Pressure

  30. Environment • Venous • Compression - compliance • Diabetic • Offloading • Foot care • Pressure ulcers: • Reduce pressure • Reduce shear / friction • Reduce moisture (Incontinence) • Increase mobility

  31. Interventions • Reduce or eliminate • Shear / friction • socks, boots, transfer sheets, • trapeze… • Moisture / Incontinence • Barrier creams / ointments • Bowel and bladder programs • Containment • Pressure • Repositioning bed and chair • Positioning devices, pressure reducing cushions • Support surfaces (mattresses) • Bridging heels

  32. Support the Host: Evaluate Systemic Factors • Tissue Perfusion • Nutrition • Infection • Medications • Diabetes • Aging

  33. Basic Principles to Optimize the Wound: Which dressing?! • M oisture • I nfection • N ecrtoic tissue • D eadspace • P rotect • I nsulate • E xudate

  34. Evidence-based Practice • Cleansing: Non-cytotoxic • Debridement: Use caution if arterial component • Dressing Choice: Base on ongoing wound assessment, principles of wound care, patient and setting • Address wound / dressing pain • Address goal and progress

  35. VHA Handbook 1180.2Assessment & Prevention of Pressure Ulcers ONS Special Issues Forum August 14, 2006

  36. Purpose of New Handbook • Establishes mandated procedures for assessment and prevention of pressure ulcers in ALL clinical settings at time of admission, upon inter- or intra-facility transfer, discharge, or other times as appropriate

  37. Scope • Identifies basic requirements for Interdisciplinary approaches to pressure ulcer: • Assessment • Reassessment • Prevention • Documentation • Relevant to all areas of clinical practice • In patient • Outpatient • Long Term Care

  38. Scope (cont) • Implements Braden Scale for: • Initial Assessment • On going assessment • Risk factors • Collaborative assessment and treatment planning essential with • Patient/resident • Family/surrogate/authorized decision maker

  39. Interdisciplinary ID Team • Must be comprised of at least: • Nurse (RN preferred, LPN &/or NA) • Primary Provider • Dietitian • Clinical Pharmacist Specialist • Rehabilitation Staff • Wound Care Specialist

  40. Wound Care Specialist • Inclusive of: • Wound Care Ostomy Continence Nurse (preferred but not required) AND/OR • Advanced Practice Nurse • Clinical Pharmacist Specialist • Rehabilitation Staff • OR any Clinician with specialized training in wound care

  41. ID Team Responsibilities • Implement education to: • Staff • Patient and/or • Caregiver and/or • Significant other • Assess all patients/residents

  42. ID Team Responsibilities (cont) • Use Braden Scale by qualified member of ID Team at time of: • Admission • Inter or intra – facility transfer • Discharge • As appropriate • Document results on ID assessment for and retain in CPRS • Formulate plan of care based on assessment

  43. ID Team Responsibilities (cont) • Acute Care: • Reassess all patients identified at risk (< 18) every 48 hours & more frequently if risk increased • Long Term Care • Reassess all residents weekly for first 4 weeks & thereafter monthly (no matter score) • HBPC • Reassess each visit if patient identified at risk • Outpatient Department • Refer all patients assessed as high risk to Interdisciplinary Team for comprehensive assessment

  44. ID Team Responsibilities (cont) • Assess nutritional status • Provide nutritional support • Consultation must be obtained with Wound Care Specialist on all patient assessed with pressure ulcers • Determine goal • Determine orders for prevention

  45. ID Team Responsibilities (cont) • Identify educational need • Record all treatment • Complete summary upon transfer or discharge of progress • Document patient outcome measures

  46. Braden Scale • Predicts individual’s level of risk for developing pressure ulcers • Scoring • 15-18 = at risk • 12-14 = moderate risk • ≤ 12 = HIGH RISK
