Description

Healthcare professionals are generally well aware of the terms pressure, shear and friction in relation to pressure ulcers. They may be less familiar with use of microclimate when discussing pressure ulcer aetiology. Whilst most will have a basic understanding of some or all of these terms, there is a tendency for eyes to glaze over when terms like perpendicular force or tangential force are used. A major strength of the consensus document is that it explains the science behind pressure, shear, friction and microclimate and then applies it to practical issues.

Description

Until recently our understanding of pressure ulcer aetiology had made little significant progress since the classic studies of the early 1960’s. These landmark experiments attempted to define the relationship between tissue damage, the magnitude of external pressures and the duration of their application.
Since the 1960’s tissue loading other than direct pressure was accepted as a cause of pressure ulcers but shear forces remained technically challenging to quantify so both their significance in pressure ulcer development and their management in clinical settings remained largely theoretical. Other extrinsic factors have been considered to increase skin and soft tissue vulnerability to prolonged or high external loads, of these the local microclimate (for example temperature and humidity) at the skin-support surface interface has long been viewed as contributing to pressure ulcer development. Like shear forces, the microclimate was challenging to quantify. In consequence little systematic progress has been made towards reducing any deleterious effects caused by changes in skin temperature or humidity.


Recent advances in measurement technologies have opened avenues of research that provide enhanced understanding of the physical effects of pressure and shear. Concurrent interest in the loaded skin’s microclimate may lead to strategies to reduce the effects of loads on the skin and soft tissues. This presentation will focus upon some of the new advances in our understanding of the effects of loading on skin highlighting where these could lead to new or improved ways of preventing pressure ulcers.

Description

The concepts involved in understanding pressure, shear, friction and microclimate, and their roles in the development of pressure ulcers are widely acknowledged to be challenging. However, comprehension of these concepts should assist clinicians in consistent and effective implementation of pressure ulcer prevention protocols.

Description

The Economics of Wound Management with focus on Patients with chronic ulcers and impact on the health care system. 

The Economics of Wound Management is a topical issue in Australia and internationally.

Dr Jan Apelqvist from Lund University in Sweden provides a comprehensive yet practical insight into the current challenges faced in the treatment of wounds from both a clinical and economic perspective.

Using the model of hard-to heal diabetic foot ulcers, Dr Apelqvist discusses the increasing demand for quality outcome data as part of the economic decision-making process and turns our attention to resource utilization efficiency and assessment of consequence rather than simplistic cost arguments. Viewers of this presentation are invited to consider the impact of current models of care that are often fragmented in their delivery and reflect on intervention vs cost over time. The information offered within the presentation is wide ranging, evidence based and succinctly melds clinical practice, economic evidence and multidisciplinary models that result in quality outcomes and effective resource utilization.
