The human and economic burden of chronic wounds is increasing (Sen et al, 2009). In the United Kingdom alone, it is estimated that over 2.2 million wounds were treated by the National Health Service in 2012/13, at a cost of between £4.5 and £5.1 billion (Guest et al, 2015). Choice of wound dressing is therefore an important factor, not only in terms of comfort for the patient, but also in optimising clinical efficiency and thereby minimising treatment time and cost.
