Integrating Palliative and Curative Wound Care Prevalence of Wounds Integrating Palliative and NPUAP (2001) Hospice population 14% – 28 % Curative Wound Care LTC and Rehab 2% – 28% SCI Units 10% – 30 % Rosene D. Pirrello, Pharmacist Specialist Palliative Care Team Tippett (2005) – 35% of 400 patients in a single hospice had a skin wound Reifsnyder and Magee (2004) – 26.9% of 980 patients at 4 hospices had pressure ulcers Outline What Types of Wounds? • Prevalence and type • Prevention • Assessment, preparation, dressing • Managing pain, odor, exudate, bleeding Types of Wounds How Many Wounds? • Pressure – 50 % • Malignant – 30 % • Venous / edematous – 10 % • Arterial – 5 % • Surgical – 5% • Diabetic – few • Skin Tears – ?

Pirrello, Pharmacist Specialist, Palliative Care Team University of California - UC Irvine Health PCQN 2014 Integrating Palliative and Curative Wound Care Wound Pain Debridement Nociceptive pain –due to chemical, • Surgery fastest, eg, scalpel, curette, scissors mechanical & thermal stimuli Aggressive – Wound edges Non-aggressive – Surrounding tissues • Autolytic (dressings) – Muscle sheaths • Enzymes – Periosteum Collagenase • Mechanical, e.g., hydrotherapy • Maggot therapy Wound Pain Neuropathic pain – due to nerve damage, death Debridement . Hyperalgesia – due to inflammation – Sensitizes & recruits REQUIRES ADVANCE PLANNING FOR PAIN – Nociceptors – Opioid receptors Allodynia TemporalProfile Plan for Pain Wound Pain Experience • Pre-medicate with analgesics / Adapted from Diane Krasner, 2010 anaesthetics • Choose analgesics to match pain temporal 1.

Use a dressing that will keep the ulcer bed Stove-top saline continuously moist. Wet-to-dry dressings 10 ml / 2 tsp salt in 1 liter / quart water should only be used for debridement and are not considered continuously moist saline Boil 3 - 20 minutes dressings Strength of evidence: A • Cleansers - more than one random controlled trial Skin – bacteriocidal Ovington L.
