A Longitudinal, Real World, Observational Registry of Chronic Wounds and Ulcers and the Patients Who Have Them

WOUNDJOURNEY is a longitudinal, real-world observational registry focused on the chronic disease burden and patient journey of individuals with chronic wounds and ulcers. Data collection began in 2005 and continues prospectively, capturing structured clinical data at the point of care using a purpose-built certified EHR or EDC system. These data are securely transmitted to the U.S. Wound Registry (USWR), a CMS-designated Qualified Clinical Data Registry (QCDR).

All major wound types are represented: Diabetic foot ulcers (DFUs), diabetic ulcers not on the foot, Venous leg ulcers (VLUs), Arterial ulcers, Pressure ulcers/injuries, Surgical complications, Traumatic wounds, Vasculitic/inflammatory, and sickle cell-related ulcers, and chronic non-pressure ulcers.

The registry collects detailed data on standard-of-care practices and advanced wound care interventions, including brand-specific information on: Advanced dressings (e.g., collagen, antimicrobial), Compression therapy, Offloading devices, Cellular and/or tissue-based products (CTPs) also called Cellular, Acellular, or Matrix-like Products (CAMPs) or "skin substitutes," Negative pressure wound therapy, MIST therapy (low-frequency ultrasound), Topical oxygen therapy (TOT), Hyperbaric Oxygen Therapy (HBOT), Topical growth factors (e.g., Becaplermin), Enzymatic and mechanical debridement, Fluorescent imaging for bacterial load, Topical antibiotics and antimicrobials, and other treatments.

The registry captures key elements of the patient journey, including: Frequency of debridement, Sites of care, number of patient visits and number of wound visits, Dressing changes, Use and timing of advanced therapies, Comorbid disease burden and clinical complexity, Patient Frailty, number of wounds and ulcers per patient, patient time in service, wound time service, patient and wound outcomes, the development of new wounds while in service and complication rates.

Wounds are risk stratified using the Wound Healing Index, enabling case-mix adjustment and longitudinal outcome tracking. Follow-up may extend over five years, capturing outcomes such as: Complete healing (epithelialization), Non-healing, Major and minor amputations, Mortality, and Loss to follow-up or transfer of care. Quality of care is assessed using wound-specific quality measures. The registry integrates real-world clinical care with research and quality improvement, supporting a learning healthcare system model.
