Every wound is unique. Like a fingerprint.

Every wound is unique — like a fingerprint, each one has its own healing signature. 10.5 million Americans are living with a wound that won't close — roughly one in six Medicare beneficiaries — and wound care costs U.S. Medicare more than $22 billion a year. A wound should close in four to twelve weeks. Chronic wounds write their own rules. ### Why no two ulcers behave the same Four forces drive chronic wounds, and every patient blends them differently: - Hyperglycemia — impairs cellular repair - Neuropathy — hides re-injury - Ischemia — starves the wound bed of perfusion - Immune loss — lets infection smolder Even within diabetic foot ulcers, ischemic waits on perfusion, neuropathic keeps re-injuring, and neuro-ischemic is both at once — the hardest to read and to heal. The best predictive models top out around 80% accuracy, and only after several tracked visits. You can't manage what you can't measure well. Hand measurements drift. Un-calibrated photos can't be compared. Every note stays a snapshot. ### From snapshots to a curve to a plan Healing Trajectory turns each visit's surface area, depth, and volume into one healing curve. When it turns back up, that's stalling — invisible visit to visit, unmistakable on the line. It reads the line, it doesn't just draw it: quantifying, flagging, verifying, and reading tissue, exudate, labs, and imaging together. Inside the Healing analytics dashboard, the whole wound story sits on one screen — measurement trends, trajectory summary, and infection assessment with ranked next actions: debride more often, use culture-guided antibiotics, check perfusion, optimize the patient, don't graft yet. Miss 50% area reduction by week four, and only 9% of diabetic foot ulcers close by week twelve. ### When the data doesn't add up A right plantar forefoot ulcer, beneath the third metatarsal — months of clean progress, then 48 hours that didn't add up. WoundScribe named the initial progress, called the recent deterioration atypical, weighed it against tissue quality, and declined to characterize the trajectory. A granulating, sloughy bed cannot be a five-centimeter deep defect — so it called it a documentation error, not clinical deterioration. Trajectory withheld. Four verification steps returned instead. No single visit looks wrong. The curve does. Every wound tells a story — WoundScribe reads it.
