Predictive validity of the Braden scale for assessing risk of developing pressure ulcers and dependence-related lesions.
In 2014, a new theoretical model explained the mechanism of the development of pressure ulcers (PUs) and that of seven types of lesions known as dependence-related lesions (DRL). The aim of this study was to calculate the incidence of DRL that have been classified as PUs and to check the predictive validity of the Braden scale for assessing DRL in accordance with the new theoretical model in an intensive care unit (ICU). Method This longitudinal, prospective study was conducted in a Spanish ICU. The patients were monitored for 14 days in the ICU until they developed DRL, died, or were discharged. The patients' risk of developing DRL was assessed each day using the Braden scale. The following parameters were taken as reference for validating the scale: sensitivity (Se), specificity (Sp), positive and negative predictive values (PPV and NPV, respectively), relative risk (RR) and the area under the receiver operating characteristic (ROC) curve. ⋯ The Braden scale has demonstrated a moderate capacity for predicting PUs and DRL caused by moisture, but no capacity for predicting DRL caused by friction.

Randomized Controlled TrialThe use of modern dressings in managing split-thickness skin graft donor sites: a single-centre randomised controlled trial.
To identify the most appropriate, most suitable and most efficient dressing for split-thickness skin graft (STSG) donor sites. Comparing the wound healing rate, pain severity and duration, as well as the dressing change frequency in four randomised patient groups. ⋯ The fastest healing time was demonstrated by patients in the TBF group. The pain was not as severe and for a shorter period of time in modern dressing study groups. However, the pain was lightest and felt shortest in TBF dressing group. The modern dressings PU and PUSM had to be changed more frequently than TBF.

The effect of negative pressure wound therapy with antibacterial dressings or antiseptics on an in vitro wound model.
The aim of this study was to investigate the bacterial bioburden in experimental in vitro wounds during the application of conventional negative pressure wound therapy (NPWT), with and without antimicrobial dressings (polyhexanide, silver), against NPWT instillation of octenidine. ⋯ Both intermitted instillation of octenidine and silver-based dressings in standard NPWT were significantly superior compared with non-antimicrobial polyurethane foam dressings or PHMB coated gauze dressing after 48 hours.

To systematically review the published academic literature on the cost of chronic ulcers. ⋯ There was large variability in study methods, perspectives, cost components and jurisdictions, making interpretation of costs difficult. Nevertheless, it appears that the cost for the treatment of chronic ulcers is substantial and greater attention needs to be made for preventive measures.
