The fourth volume of "Trends in Wound Care" focuses on two particular wound types: leg ulcers and pressure ulcers. These wounds account for a large proportion of the demands made on the time and financial resources available within wound care. It is therefore important that we equip ourselves with the available knowledge in order to make best use of these resources. In addition, care of patients with leg ulcers and pressure ulcers is of topical interest. This is in some part due to the difficulty in ascertaining prevalence rates as recent, accurate and widespread prevalence data of these wounds is not available in the public domain. It would seem appropriate that the move towards bench-marking would encourage the gathering and publication of this data on a national scale. Within the overall theme in this volume, the focus remains on improving patient outcomes and reducing morbidity. It is for this reason that chapters included also examine assessment, principles of management and key considerations in dressing selection.We hope that you enjoy this latest addition to the "Trends in Wound Care" series that provides an update and easy reference source within this fascinating field of care.
