When responding to OASIS questions about the healing status of wounds, look to this guidance from the Wound Ostomy and Continence Nurses Society (WOCN).
WOCN Wound Healing Criteria
0 -- Newly epithelialized
1 -- Fully granulating
2 -- Early/partial granulation
3 -- Not healing
Wound with ≥25% avascular tissue (eschar and/or slough) or Signs/symptoms of infection or
Clean but non-granulating wound bed or
Closed/hyperkeratotic wound edges or
Persistent failure to improve despite appropriate comprehensive wound management.
Note: A wound need only show one of the response 3 criteria listed to be considered not healing.
