    Abstract
    Knowledge of clinically and cost-effective wound management is an obvious requirement for surgeons, yet wound care education rarely features within the medical curriculum. As a result surgical trainees are often poorly placed to join in multidisciplinary wound management and may feel threatened when asked to manage wound complications. A vast range of dressing products exists yet robust evidence of the function and effectiveness of individual products is often lacking. An understanding of wound pathophysiology, a defined treatment goal and regular wound assessment combined with knowledge of basic wound dressing categories will provide guidance on product selection for different clinical situations and wound types.

      Wound dressings: principles and practice

      Oestrogen promotes healing in a bacterial LPS model of delayed cutaneous wound repair

      Crompton, R.; Williams, H.; Ansell, David M.; Campbell, Laura; Holden, K.; Cruickshank, S.; Hardman, M.J. (2016-04)
      Wound infection is a major clinical problem, yet understanding of bacterial host interactions in the skin remains limited. Microbe-derived molecules, known as pathogen-associated molecular patterns, are recognised in barrier tissues by pattern-recognition receptors. In particular, the pathogen-associated molecular pattern, lipopolysaccharide (LPS), a component of microbial cell walls and a specific ligand for Toll-like receptor 4, has been widely used to mimic systemic and local infection across a range of tissues. Here we administered LPS derived from Klebsiella pneumoniae, a species of bacteria that is emerging as a wound-associated pathogen, to full-thickness cutaneous wounds in C57/BL6 mice. Early in healing, LPS-treated wounds displayed increased local apoptosis and reduced proliferation. Subsequent healing progression was delayed with reduced re-epithelialisation, increased proliferation, a heightened inflammatory response and perturbed wound matrix deposition. Our group and others have previously demonstrated the beneficial effects of 17β-estradiol treatment across a range of preclinical wound models. Here we asked whether oestrogen would effectively promote healing in our LPS bacterial infection model. Intriguingly, co-treatment with 17β-estradiol was able to promote re-epithelialisation, dampen inflammation and induce collagen deposition in our LPS-delayed healing model. Collectively, these studies validate K. pneumoniae-derived LPS treatment as a simple yet effective model of bacterial wound infection, while providing the first indication that oestrogen could promote cutaneous healing in the presence of infection, further strengthening the case for its therapeutic use.

      A new methodology for costing wound care

      Harding, K.; Posnett, J.; Vowden, Kath (2013)
      Increasing pressure on health care budgets highlights the need for clinicians to understand the true costs of wound care, in order to be able to defend services against indiscriminate cost cutting. Our aim was to develop and test a straightforward method of measuring treatment costs, which is feasible in routine practice. The method was tested in a prospective study of leg ulcer patients attending three specialist clinics in the UK. A set of ulcer-related health state descriptors were defined on the basis that they represented distinct and clinically relevant descriptions of wound condition ['healed', 'progressing'; 'static''deteriorating; 'severe' (ulcer with serious complications)]. A standardised data-collection instrument was used to record information for all patients attending the clinic during the study period regarding (i) the health state of the ulcer; (ii) treatment received during the clinic visit and (iii) treatment planned between clinic visits. Information on resource use was used to estimate weekly treatment costs by ulcer state. Information was collected at 827 independent weekly observations from the three study centres. Treatment costs increased markedly with ulcer severity: an ulcer which was 'deteriorating' or 'severe' cost between twice and six times as much per week as an ulcer which was progressing normally towards healing. Higher costs were driven primarily by more frequent clinic visits and by the costs of hospitalisation for ulcers with severe complications. This exercise has demonstrated that the proposed methodology is easy to apply, and produces information which is of value in monitoring healing and in potentially reducing treatment costs.
