CARRION JIMENEZ, Andoni et al. Cost efficiency of the choice of dressings in chronic wounds with biofilm based on a theoretical model. Gerokomos [online]. 2017, vol.28, n.2, pp.98-102. ISSN 1134-928X.

Choosing the right dressing is one of the most important preoccupations in advanced wound healing. On the one hand, a constant development of wound dressings is found and, on the other, an increasing concern about the impact of a correct indication on costs. One of the factors increasing costs is wounds' torpid evolution, being the presence of biofilm one of the reasons of this bad evolution. Wound care managing biofilm is one of the biggest challenges for the clinicians.


To evaluate the cost efficiency of a hydrofiber dressing with silver, EDTA and benzethonium chloride as first choice in dressing wounds with the presence of biofilm.


Using a theoretical model of chronic wounds divided into two groups and considering that 60% of the wounds of both groups have biofilm, have compared the costs of using an alginate dressing with silver as first choice in a first group and a hydrofiber dressing with silver, EDTA and benzethonium chloride as the first choice in the second group. To calculate costs, a public tender for dressings costs by the Provincial logistics platform in Seville has being considered.


The average cost wound / day for wounds of the first group is 0.59€ while for the second group is 0.55 €.


Hydrofiber dressing with silver, EDTA and benzethonium chloride is the dressing of choice and cost-effective dressing against the other compared dressing.
