2 I am speaking to you as an independent physician, no entity paid for my travel and I will not receive an honorarium for my presentation Full time employed Professor of Surgery at the University of Illinois Hospital and Health Sciences System I am currently not on any industry scientific advisory board or speaker s bureau I am a consultant to Accelecare wound centers, a management company in Bellevue WA

3 Field of wound care 1962, 1978, 1982, 1998

4 The Scope of the Problem 14 billion dollar global industry US 2 billion dollar market, with a CAGR of 10% between 2010 and % US population > 65 in 2020 Elderly have more chronic disease states Increased venous ulcerations Increased peripheral arterial disease, amputations, stroke, MI etc. 8% US diabetic, 15% develop a diabetic foot ulcer 67% US population is overweight Increases in surgical procedures

5 The Scope of the problem Chronic wounds lead to lost days of work, decreased quality of life, depression Acute wounds with substandard treatment can transition into chronic wounds Complications from surgical wounds can lead to increased length of stay, higher healthcare costs and readmissions Pressure ulcers can impact the most vulnerable populations, the elderly and spinal cord injured patients

6 The scope of the problem

7 CER Need for better evidence Gaps in quality and efficiency in health care 18% GDP, 2009 or 2.5 trillion By 2025 will be > 25% GDP Up to 30% of spending reflects medical care of uncertain or questionable value IOM reports <50% of treatments delivered are supported by evidence

8 Wound care is Unique? Is it? Treatments take a long time Treatments can span sites of care Not all patients can be cured/healed Access to care can be compromised Nutritional issues Psychological impact of disease on patient and care providers Costly therapy

9 Wound care is Unique? Is it? Complex group of patients with a highly prevalent condition that has a large economic impact on the healthcare industry Innovation can be slow based on regulatory pathways, product adoption, poorly defined endpoints, Clinical situations often require clinicians to use multiple agents at the same time or in sequence despite research based on each treatment utilized as a stand alone therapy

10 The last two slides could be used in a presentation focused on Oncology, Transplantation, Connective tissue disorders, Spinal cord injury, etc.

11 Wound Care Patients Medically complex but unlike most other medical conditions, the wound is a manifestation of a collection of underlying co-morbid conditions. This potentially confounds the treatment directed at the wound surface and complicates research. Currently treatments are currently regulated based on their impact on complete healing A cancerous lesion might be treated with neo-adjuvant chemo to shrink the mass, followed by surgical excision, followed by radiation therapy Each therapeutic step would be assessed on its ability to achieve the desired outcome

12 Wound Care Patients Standard of care Has been decided in wound care but wide variation exists within each subcategory Debridement- High powered venturi effect water based removal of full thickness slough is a debridement, use of a sterile 2mm curette is a debridement. Offloading, Moist environment, bioburden control, Oncology- removal of colon and harvesting nodes is fairly uniform Need to agree upon SOC in all trials

14 Donaldson BMJ 2002 Declining effectiveness Problem Between /46 studies with economic outcomes ended up with results in box C1 So recommendations to approve due to increasing cost effectiveness but leads to overall increase in cost Problems with allocative efficiency A? B C? Increasing cost

15 Can we predict who will heal? How long should it take What treatments should we use In what order / In what setting If they heal will it stay healed Will/Can the patient adhere to protocol What are the goals and objectives of the patient and do they have access Centers of Excellence Economic alignment for total episode of care

16 Site of Care Outcomes Table 1. The Overall Healing Rate and the Mean and Median Time to Healing from Two Sources 2008 Third Congress of the World Union of Healing Societies, Toronto, Canada *Ref Ennis et al Ostomy/Wound Management 1998;44(11):22-39 Communit y Hospita l-based Outpati ent Clinic* Number of Wounds Tertiary care Hospit al Outpati ent Clinic Wounds Healed 225 (74%) 252 (73%) Kaplan Meier derived mean time to healing 14± 1 12 ± 1 Kaplan Meier derived median time to healing 9 ± 1 9 ± 1

21 Solutions? Think about the trial designs required for wound care technologies of the near future Registries, SOC, Use product/technology to achieve specific physiological endpoints Cell therapy, gene therapy, small molecular weight proteins, systemic pharma based therapy, scaffoldings with active cytokines etc. Think about quality of healing, how important is total healing if it only lasts for 3 weeks? Non invasive diagnostic methods to assess quality of healing need to be developed Consider patient focused outcomes and include patient input in trial design of future innovations
