There is no single, agreed point at which a wound should be seen by a wound care specialist. What can be described is what a wound care center is, what its team does, and the signs that mean you should contact a clinician.
A wound care center is a medical facility for treating wounds that do not heal.
The team there examines and measures the wound, checks the blood flow in the area around the wound, works out why it is not healing, and creates a treatment plan. The team includes providers who oversee your care, nurses who clean and dress the wound and teach you how to care for it at home, and physical therapists who help with wound care and work with you to help you stay mobile.
Wounds commonly treated in these settings are pressure sores, surgical wounds, radiation sores, and foot ulcers due to diabetes, poor blood flow, chronic bone infection, or swollen legs.
A general rule of thumb for the public describes a wound as non-healing if it has not started to heal in two weeks, or has not completely healed in six weeks. That is general guidance. It is not The WISH Clinic’s definition, it is not a universal standard, and it is not a referral rule. What “non-healing” means, and why different cutoffs are used, is covered on its own Wound Wizard page.
What those numbers point to is the underlying idea rather than a deadline: a wound that is not progressing is the kind of wound these centers exist to assess. Whether that describes your own wound is a judgment for a clinician who can examine it.
