  • Maintenance wound: the wound could heal, but the cause is not corrected due to patient unwillingness to adhere to treatment or a lack of required system resources
  • Non-healable wound: the patient is ill or may have negative protein balance or inadequate blood supply that is not bypassable or dilatable
Q: Is the ulcer healable?  Healable ;Non-healable;Maintenance

Conduct noninvasive arterial tests

Conduct noninvasive arterial tests to rule out periphery arterial disease. See table with values and interpretations in topic "How to Select Adequate Compression Therapy Pressure Levels and Products"

Q: ABI results?  Normal (values) ;Abnormal (values)

Is hospital admission indicated?

If any of the following are selected -> yes

If none are selected -> no

Q: Does the patient show signs of any of the following?  Surgical debridement needed (e.g. extensive necrosis) ;Postoperatice complications requiring surgical interventon;Systemic infection (e.g. sepsis or SIRS) ;Necrotizing soft tissue infection

Manage according to Staging


[Admit to hospital]


STAGE 1: Manage underlying causes

Local Wound Care for Stage 1

Q: Notes  

Local Wound Care for Stage 2

Comprehensive local wound care including cleansing, control of  bioburden, barrier cream or wound moisture balance with appropriate dressing and periwound skin protection


HealableNon-healable/maintenance
Cleansing
  • Gently cleanse with sterile saline, water, 0.5-1% acetic acid, or wound cleanser
  • If solution cannot be retrieved/aspirated (due to undermining, sinuses, etc.), use forceps to hold moistened gauze ribbons and cleanse the wound. Ensure all gauze is retrieved.
  • Keep wound bed dry   
  • May cleanse ulcers with antiseptic agents to help manage bioburden, odor and moisture
Debridement
  • Stage 1 and 2 PU/PI: debridement not indicated
  • For Stage 1 and 2: do not debride
Infection and Bioburden Control
  • If no signs of infection, do not use antimicrobial dressings

Local Wound Care for Unstageable PU/PI

Conduct debridement: stage can only be determined when enough slough and/or eschar is removed to expose the anatomic depth of soft tissue damage involved


HealableNon-healable/maintenance
Cleansing
  • Gently cleanse with sterile saline, water, 0.5-1% acetic acid, or wound cleanser
  • If solution cannot be retrieved/aspirated (due to undermining, sinuses, etc.), use forceps to hold moistened gauze ribbons and cleanse the wound. Ensure all gauze is retrieved.
  • Keep wound bed dry   
  • May cleanse ulcers with antiseptic agents to help manage bioburden, odor and moisture
Debridement
  • Stages 3 and 4 PU/PI, unstageable PU/PI due to slough/eschar: debridement indicated for removal of devitalized tissue at initial assessment and on a regular basis until wound bed is covered with granulation tissue; for wounds with no signs of improvement despite standard care for 2 - 4 weeks; and for infected wounds. 
  • If dry eschar in ischemic limb: do not debride; monitor for signs of infection
  • Choice of debridement methods:
    • Choice depends on patient condition and resources (clinician's skills, license restrictions, resources available). 
    • For PU/PI with extensive necrosis, Stage 3 or 4 with undermining, sinus tracts or signs of infection (i.e. advancing cellulitis, crepitus, fluctuance, and/or sepsis secondary to ulcer-related infection): initial surgical debridement in the operating room is recommended  
    • If there is no urgent clinical need for drainage or removal of devitalized tissue: sharp conservative, mechanical, enzymatic, autolytic and/or biological debridement may be used
    • Sensate patients may not tolerate sharp debridement at the bed side and may need to be debrided in the operating room
  • For dry, stable eschars without fluctuance or erythema: do not debride

Q: Notes  

Local Wound Care for DTI

  • Protect affected skin with moisture barrier products and skin protectants
  • DTI can quickly evolve to Stage 3 or 4 PU/PI despite adequate care. If this evolvement occurs, PU/PI should be managed as Stage 3 or 4 accordingly
  • There are anecdotal data on the use of non-contact low frequency ultrasound for deep tissue injury [12][13]
Q: Notes  

For healable ulcers: signs of improvement in 2-4 weeks?

Q: Notes  

Continue treatment until completed healing, prevent new PU/PI


Reassess PU/PI

Q: For all healable PUs/PIs: Check differential diagnoses  
Q: For all healable PUs/PIs: is the cause being adequately addressed?  Checked for adequate pressure redistribution, repositioning, transfer and plan to increase mobility;Checked for adequate glycemic control and nutritional intake;Checked for adequate moisture/incontinence management;Checked for any co-factors that may be impeding healing (e.g., medications, smoking, immunosuppression, etc).;Checked for soft tissue infection and/or osteomyelitis;If applicable: checked for presence of any "acquired bursa" between the skin and underlying bone or at the base of the ulcer.;If ulcer is on lower extremity: checked for adequate vascular supply to the ulcer
Q: For all healable PUs/PIs: are patient's concerns addressed?  
Q: For all healable PUs/PIs: is local wound care adequate?  Debridement: checked for adequate removal of devitalized tissue and surrounding callus;Bioburden: checked for adequate management;Dressings: checked for excess exudate management, periwound protection, moist wound bed
Q: For infected PUs/PIs: assess the following factors  Checked for presence of unidentified necrotic soft tissue or bone;Checked for presence of an undrained abscess;Checked for presence of osteomyelitis that has not yet responded;Checked for presence of an untreated or an unidentified pathogen;Checked for presence of an antibiotic delivery problem;Checked for presence of an antibiotic non adherence issue;Checked for correction of any metabolic aberrations

Create new care plan

  • Generate care plan that addresses any factors or co-morbidities impairing healing
  • Biopsy or swab with validated method such as Levine technique to rule out infection/ osteomyelitis.
  • Consider use of adjunctive therapy 
  • For large ulcers, if important anatomical structures are exposed (e.g., vessels, tendon, nerves), or if osteomyelitis is present, consider surgical reconstruction with flaps if ulcer is large
  • Place consults/referrals as needed: Infectious disease specialist, physical therapist, occupational therapist, plastic surgeon, vascular specialist, behavioral medicine
