RESUMO
As part of an infection management protocol, antimicrobial dressings offer an appropriate, cost-effective choice for the management of localised bioburden in chronic wounds. The choice of antimicrobial can impact significantly not only on the treatment outcomes and cost but also on the safety and well-being of the patient. This retrospective study investigates these outcomes comparing health care records of 2572 patients with open chronic wounds, who were treated either with an Integrated Care Wound Bundle (ICB) including nanocrystalline silver (NCS) dressings (n = 330) or without NCS dressings and not on a ICB (n = 2242) in the community from March 2016 to March 2018. Wounds treated in the NCS dressing treatment bundle had a mean healing time of 10.46 weeks, vs 25.49 weeks for the non-ICB treated wounds. In addition, the average interval time between dressing changes was in favour of the NCS dressing treatment bundle (3.98 vs 1.87 days), contributing to a substantial reduction in mean treatment labour costs ($1251 vs $6488). The use of a NCS dressing demonstrated improved efficacy and cost effectiveness of labour required for chronic wound management; highlighting the importance of choosing an effective antimicrobial dressing as part of an infection management protocol.
