Wound Care

The global market for wound care encompasses traditional dressings and bandages, as well as advanced wound care products such as bioengineered skin and skin substitutes and wound care growth factors. Over the past 30 years, there has been a shift from traditional wound dressings towards advanced therapies that aim to optimize the wound healing environment. Advanced wound care is composed of biocompatible products that are intended to actively promote wound healing by interacting either directly or indirectly with wound tissues. Attempts to reduce the duration of hospital stays in order to limit healthcare costs and the goal of enhancing therapeutic outcomes are driving the demand for advanced wound care and closure products. One of the primary market drivers for advanced wound care products is the increasing incidence of chronic wounds, which are on the rise due to an aging population and a sharp rise in the incidence of diabetes and obesity worldwide. Both advanced age and chronic medical conditions are associated with a slower healing process, and all phases of wound healing are affected. The inflammatory response is decreased or delayed, as is the proliferative response. Espicom estimates that the global market for advanced wound care in 2013 had reached $6.2 billion, representing a growth rate of approximately 5% since 2012.

With a wide range of dressings to choose from, dressing selection is a significant challenge for wound care clinicians. The ideal dressing should induce rapid healing at reasonable cost with minimal inconvenience to the patient. In a healing wound, a cascade of events occurs that includes platelet accumulation, inflammation, fibroblast proliferation, cell contraction, angiogenesis, and re epithelization, ultimately leading to scar formation and wound remodeling. Collagen plays an important role in each of these phases of wound healing. Native intact collagen provides a natural scaffold or substrate for new tissue growth. Dressings containing collagen are thought to provide the wound with an alternative collagen source that is degraded over time, leaving the endogenous native collagen to continue normal wound healing.

Advanced wound dressings have the benefit of forming part of the natural tissue matrix and some of them play an important role in natural wound healing and new tissue formation. These characteristics make them the most attractive and fastest growing segment of the overall advanced wound care market, experiencing double digit growth in 2013. In certain instances, these matrices are incorporated with compounds such as growth factors and antimicrobials for delivery to the wound site. There are a number of advanced wound care dressings available that incorporate tissue derived collagen to enhance wound bed preparation.
