NPWT or HRT-dressing? Results of an expert panel and a Delphi panel analysis.
OBJECTIVE
To investigate the similarities and differences between Hydration Response Technology (HRT) and negative pressure wound therapy (NPWT) with regard to wound bed preparation, and to devise a set of recommendations for their use on the basis of the opinion of two panels.


METHODS
An expert panel that analysed in vitro and clinical data as well as the similarities and differences between the two modalities was established. This culminated in a series of recommendations on which modality to use for which indication. These recommendations were presented to a Delphi panel, consisting of users of both NPWT and HRT-dressing. The panel was then asked to produce its own recommendations.


RESULTS
The outcomes and recommendations of both panels were reported. NPWT is the preferred treatment modality for abdominal dehisced wounds, and to a lesser extent, for surgical wound healing by secondary intention. For all other indications, the treatment modalities are at least equal, with HRT-dressing often being the superior mode to treat wounds such as venous leg ulcers, arterial ulcers and vasculitis.


CONCLUSIONS
In the opinion of the expert panel and the Delphi panel, both modalities share a number of clinical and non-clinical properties. However, because of the numerous advantages of HRT technology, HRT dressing has the potential to replace NPWT in a number of indications, where the patient, health-care providers and institutions may benefit.
