  5. 5. Chronic wounds: The overall incidence of venous stasis syndrome and venous ulcer were 76.1 and 18.0 per 100,000 person-years, respectively. The incidence of both was higher in women than in men (83.7 vs 67.4 per 100,000 person-years for venous stasis syndrome; 20.4 vs 14.6 per 100,000 for venous ulcer) and increased with age for both sexes.

  7. 7. Chronic wounds: the facts Chronic or nonhealing ulcers: -defective remodeling of the extracellular matrix, -a failure to reepithelialize, -and prolonged inflammation. Monitoring of acute and chronic wounds: by measuring in an objective, precise, and reproducible way
  8. 8. Middle Ages?
  9. 9. Chronic wounds: 1. the prevalence and cost of managing chronic wounds continue to escalate, 2. despite the availability of advanced wound care products , specialists and consultants , and the creation of risk assessment tools and wound healing centers. 3. serious morbidity and financial costs precipitated by these wounds, 4. a serious call is made to health care providers, payers, and policymakers to revisit the way such wounds are managed today.
  10. 10. Chronic wounds: the problem 1.Treatment decisions are based on visual perception . 2.Descriptive analysis of wounds is poorly standardized and rarely reproducible . 3.The assessment and measurement of the temporal changes of wounds using digital images can now be calibrated, reducing the difficulty of obtaining reproducible color content . The color content of the images becomes independently of any camera settings and illumination features. 4. Growing demand for randomized clinical trials, health technology assessments and increasing economical pressure on health budgets: optimal data sharing with standardization and agreements on universals and instances . 5. Consistent, controlled and universally accepted vocabularies seems essential for documenting, describing and comparing wounds. 6. Ontologies (controlled vocabularies) promise to help address many of the difficulties currently experienced in managing large image databases.

  12. 12. non-invasive wound assessment by image analysis: Wound bed preparation - a procedure aimed at assisting clinicians in wound bed assessment and the development of strategies to maximise healing potential - is now recognised as an important aspect of care. The Red-Yellow-Black-scheme is commonly used for classifying chronic wounds. S implified direction for selecting appropriate dressings for open wounds by focusing on the phase of healing as evidenced by the predominant condition of the wound base The associated development of the TIME framework (Tissue management; Inflammation and infection control; Moisture balance; Epithelial (edge) advancement) offers clinicians a practical tool for translating wound bed preparation into practice.

  14. 15. non-invasive wound assessment bymage analysis: measurement Wound measurement and assessment is important for several reasons including: Tracking patient progress to ensure that healing of a specific wound is progressing with the selected treatment regime  Allowing institution managers to audit patient progress and institution effectiveness Building a reliable and consistent database for outcomes based studies of wound care Improving patient compliance Consistently documenting patient care for reimbursement purposes and for protection of the health care provider against litigation.

  17. 18. 1. a free accessible database and archive system for high-quality multidimensional digital images of wounds, with their supporting metadata. 2. anonimized images and their metadata available electronically for personal study, educational (clinical dicision support systems), commercial, medical and scientific research purposes. 3. tools and interfaces to assist in the submission, discovery, downloading and visualization of such images, and making comparisons between them. 4. links between these images and relevant items including semantics, clinical information, ontologies , etc. 5. facilitate effective data representation and information visualisation through the construction of adaptive interfaces that meet the needs of individual users. 6. To provide tools for assisting in annotation of wound images and the development of ontologies related to these images. 7. To develop theoretical (mathematical, colorimetric,...) models related to the language and terminology used by the wound care community.
