The Reliability and Validity of Color Indicators Using Digital Image Analysis of Peristomal Skin Photographs: Results of a Preliminary Prospective Clinical Study
Index: Ostomy Wound Manage. 2014;60(3):12–29.
Accurate assessment is necessary to evaluate peristomal skin condition, but objective methods are lacking. The purpose of this prospective, repeated-measures study was to evaluate the reliability and validity of color indicators using digital image analysis of peristomal skin photographs. The 6-month study was conducted among 21 patients (mean age 65.1 years old, 15 men) with ostomies (14 colostomies, six ileostomies, and one urostomy) at four outpatient clinics. Photographs taken by nurses of the peristomal area using point-and-shoot cameras were processed using digital image analysis, which involved color calibration, image processing, and indicator calculation. An erythema index (EI), melanin index (MI), and hypopigmentation index were created to represent increased degrees of red, black, and white color, respectively, and their average values in the peristomal region of an image were calculated relative to values for intact skin.
Use of a Portable, Single-use Negative Pressure Wound Therapy Device in Home Care Patients with Low to Moderately Exuding Wounds: A Case Series
Index: Ostomy Wound Manage. 2014;60(3):30–36.
Negative pressure wound therapy (NPWT) is widely used in the management of acute and chronic wounds. The purpose of this 8-week study was to evaluate outcomes of using a new canisterless, portable, single-use NPWT system in patients with wounds treated in a Canadian community healthcare setting. The device is designed to provide negative pressure at 80 ± 20 mm Hg, 24 hours a day of continuous usage, for a maximum wear time of 7 days. Data on wound outcomes, including exudate levels, wound appearance, and wound area, were collected weekly by a Registered Nurse as part of routine practice.
Loofah Sponge as an Interface Dressing Material in Negative Pressure Wound Therapy: Results of an In Vivo Study
Index: Ostomy Wound Manage. 2014;60(3):37–45.
Since the introduction of negative pressure wound therapy (NPWT), the physiological effects of various interface dressing materials have been studied. The purpose of this experimental study was to compare the use of loofah sponge to standard polyurethane foam or a cotton gauze sponge. Three wounds, each measuring 3 cm x 3 cm, were created by full-thickness skin excision on the dorsal sides of 24 New Zealand adult white rabbits. The rabbits were randomly divided into four groups of six rabbits each. In group 1 (control), conventional saline-moistened gauze dressing was provided and changed at daily intervals. The remaining groups were provided NPWT dressings at -125 mm Hg continuous pressure.
OWM: Please provide a short description of your background, training, and experience.
As a scientist, I have over 20 years of hands-on experience in the research and development of medical devices, including products for acute, chronic, and combat wound care. My technical expertise is in micro- and nano-technologies and system engineering. As an entrepreneur, I have extensive knowledge of the medical device industry and try to apply an innovative approach to business development and the introduction of new products. I am an inventor of over 100 United States and international patents, many of which have served as a basis for new products, processes, and companies. I hold an MSEE and PhD in Technology.
OWM: Please describe your education, training, and work experiences that have prepared you for your current position as the VP of the Critical & Chronic Care Division at 3M.
I have been with 3M’s Health Care Business for over 10 years, but I started my 3M career in the United Kingdom 28 years ago. I have worked in several different 3M businesses and divisions since that time, including the 3M Electronics and Energy Business and the 3M Industrial Business. I gained extensive healthcare experience while working in Europe, specifically in the United Kingdom, Germany, the Czech Republic, and Belgium, as well as in Singapore. Prior to joining 3M Critical & Chronic Care Solutions, I headed up 3M Unitek, our orthodontics business.

Quality and safety cannot be separated. Although many healthcare organizations have separate committees and reporting mechanisms for each area, quality and safety affect the patient concurrently.
Additionally, patient safety and caregiver safety are intertwined. If a caregiver performs a task that is unsafe to his/her own well-being and is injured, this can have a negative impact on the patient. For example, an employee who injures her back and is dealing with pain may not be concentrating as much on the patient as on her own situation, overextending her capabilities or under-providing care.
