Treatment of a Chronic Foot Ulcer with “SNaP” Mechanically Powered, Ultra-Portable, Negative Pressure Wound Therapy: A Case Study

Background

Grade 4 pressure ulceration is full thickness tissue loss, which can include undermining and tunnelling.  Stage 4 ulcers can extend into muscle and supporting structures, with a risk of osteomyelitis (EPUAP 2014) . The impact for the patient is frequently debilitating with a negative impact on the patient’s quality of life and that of their relatives.  The impact for the health service is prolonged treatment times, increased costs and extra strain on resources.  The costs associated with treating pressure ulcers in the U.K. vary, but these costs represent a significant burden on the NHS, which is likely to increase as a result of an increasingly ageing population.  A study in 2004 estimated the costs of treatment varied from £1,064 for a grade 1 pressure ulcer to £10,551 for a grade 4 pressure ulcer.  The total cost of treating pressure ulcers in the UK was estimated to be £1.4 - £2.1 billion annually, which was 4% of total NHS expenditure and significantly most of this cost was for nursing time. (Bennett 2004)

Aims

To show resolution of a non-healing grade 4 pressure ulcer using SNaP Negative Pressure Wound Therapy, the positive impact on quality of life and cost effectiveness against long term use of conventional dressings.
