Hydration response technology dressings for low to excessively exuding wounds: a systematic review.

Objective: The aim of this systematic review was to identify and qualify the current available evidence of the wound exudate handling capabilities and the cost-effectiveness of hydration response technology (HRT). HRT combines physically modified cellulose fibres and gelling agents resulting in wound dressings that absorb and retain larger quantities of wound exudate.

Method: A systematic search was conducted in MEDLINE (via PubMed and PubMed Central) according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The search was conducted using an unlimited search period. Studies or reviews that evaluated effect on wound exudate and cost-effectiveness, as well as the impact on wound healing were considered. Records focusing on wound management using HRT devices were included.

Results: The literature search identified four studies and one comparative analysis, ranging from low to moderate quality, that compared HRT dressings to other interventions (carboxymethyl cellulose dressing, other superabsorbent dressings, negative pressure wound therapy).

Conclusion: The analysed data supported the beneficial use of dressings with HRT for exuding wounds which was characterised by fewer dressing changes, improved periwound skin conditions and reduced costs.
