Wound care innovation for the tropics
Chronic non-healing wounds (diabetic foot ulcers, pressure injuries, and venous leg ulcers) disproportionately affect the elderly population. Tropical climate further complicates the prognosis of chronic wounds as a humid and warm environment is favourable for bacterial infection. Chronic wounds such as diabetic foot ulcers often lead to amputations and pose significant health care challenges to clinicians. Singapore has the second-highest proportion of people with diabetes among developed nations and roughly around four diabetes-related amputations in a day. Better care and treatments for diabetic foot ulcers and other chronic wounds could prevent poor prognosis and save lives. Chronic wounds incur high costs and negatively impact mobility, well-being, and quality of life.
Our Approach
The Wound Care Innovation for the Tropics (WCIT) programme is a first-of-its-kind research program focusing on wound care in tropical climates. Our focus is to transform the care of chronic wounds, deliver better health outcomes and reduce economic burdens.
Our approach encompasses the following areas of research
- World's largest library of Asian chronic wound samples to identify biomarkers and drug targets.
- Develop innovations in advance dressings, diagnostics, and practice support patients.
- Improved wound models to support preclinical testing.
- First central wound registry in Asia with over 800 patients to improve health service delivery.
- Forge strong clinical ties with five new wound-focused center's set up in Singapore in the past two years.
By accelerating the development of novel wound care therapies and practices, our programme aims to position Singapore as a new focal point in Asia for its world-class research and development in the field of chronic wounds.
Key Projects
Multi-Omics technologies for investigation of biomarkers
The 'Omics' approach applies cutting-edge technologies to comprehensively profile biological molecules (biomarkers) in the body, such as proteins, metabolites, and wound microbes.
In particular for wound care research, the discovery of biomarkers for chronic non-healing wounds is done using the largest library of wound samples in the world with >2,000 samples from 250+ multi-ethnic patients in Singapore.
These biomarkers can provide unprecedented insight into diabetic foot ulcers and venous leg ulcers, and guide a new generation of diagnostic, prognostic and therapeutic applications for improving wound care.
Platform Technology – in vitro and in vivo models of wound healing
The Asian Skin Biobank has various in vitro wound models that enables the evaluation of novel wounds. This Skin-in-a-dish model is developed from human skin reconstructed ex vivo using de-cellularised native human dermal scaffolds and donor keratinocytes.
Another breakthrough innovation is the world’s first perturbed wound healing in vivo model which recapitulates many features of human chronic wounds. This was developed by Prof David Becker, who has a joint appointment with SRIS and NTU.
Singapore Wound Registry
This is the world’s first major wound care registry based on Asian data in a tropical climate. It has collected anonymised information from >800 patients on Venous Ulcers, Pressure Ulcers and Diabetic Foot Ulcers from major hospitals in Singapore. Data on patients with chronic wounds were also analysed retrospectively.
This Wound Registry collaboration provides healthcare practitioners with practical insights for improved clinical protocols and better patient outcomes.
Pressure Sensors for Venous Leg Ulcers
Sensors are incorporated into the compression bandage to measure pressure. This innovation could be used in the training of nurses so they apply the correct amount of pressure when bandaging patients’ venous leg ulcers, to improve the effectiveness of compression therapy. The sensors are made of thin multi-layer film consisting of an array of micron-sized chambers, each filled with dye solution. Upon compression, the microchambers will rupture and release the dye to indicate that sufficient pressure has been achieved.
Haloflow for Prediction and Evaluation of Diabetic Foot Ulcers
This Haloflow system enables the detection of early phase micro- and macro-vascular disease in diabetic patients before serious clinical manifestations appear. Assessments can be done non-invasively using a portable hand-held probe.
Antibacterial and Bio-functional Wound Dressings
Cationic hydrogel dressings that are highly effective against bacteria and biofilms. They are available as stable non-leaching gels as well as leaching gels that can release active components in response to bacterial enzymes, and be easily incorporated into dressings.
