title: Providing cost-effective treatment of hard-to-heal wounds in the community through use of NPWT.
abstract: OBJECTIVE
  The treatment of non-healing wounds accounts for a high proportion of wound care costs. Advanced technology treatments, such as negative pressure wound therapy (NPWT), could be cost-effective if they result in faster healing. The objective of this study is to assess the effect on healing and the cost-effectiveness of a single-use NPWT (i.e PICO by Smith & Nephew) when used on hard-to-heal wounds in a community setting.
  
  
  METHODS
  This was a cohort case study in which wounds were treated with NWPT for 2 weeks. Wounds were assessed every 2-4 weeks to a healed state. The weekly cost of treatment prior to intervention, that is, the products used and nurse time, were compared with treatment costs associated with NWPT and after a return to standard treatment.
  
  
  RESULTS
  The study included 9 patients with leg ulcers or pressure ulcers that had been slow healing or non-healing for at least 6 weeks. While treated with NPWT, the average weekly reduction in wound size was 21%. The wound size achieved with NPWT was reached on average 10 weeks earlier than predicted. The increased healing rate continued after PICO stopped and 5 wounds healed on average 8 weeks later. Frequency of dressing changes fell from 4 times weekly at baseline to 2 times a week with NPWT and to 1.8 after NPWT stopped. Weekly cost of treatment with NPWT was, on average, 1.6 times higher than the baseline, but fell to 3 times less when NPWT stopped owing to the reduction in dressing changes. The amount of change in healing rate was considerably higher than the increase in costs associated with NPWT.
  
  
  CONCLUSIONS
  NWPT is a cost-effective treatment for hard-to-heal wounds. Wounds decreased in size and healed more quickly under NWPT treatment than under standard treatment. Additional NPWT costs can be quickly offset by faster healing and a shortened treatment period.
