Debating the relative unimportance of pressure-reducing equipment

Abstract:
This article examines some assumptions underlying the provision of pressure-reducing equipment, and argues that failure to 'act first and ask questions later' may be a key source of pressure damage. Indeed, it is argued that prevention of pressure damage can be simplified by identifying three groups of patients: those who have pressure ulcers; those who will develop them in faction is not taken; and those who will not get them. The linkage of risk assessment scores and guidelines is challenge as erroneous and misleading.
