NPWT resource use compared with conventional wound treatment in subcutaneous abdominal wounds with healing impairment after surgery. SAWHI randomized clinical trial results.

This study included 539 patients with an abdominal wound. Negative pressure dressings reduced hospital stay (11.8 versus 13.9 days P=0.047), but duration of actual treatment within 42 days longer: 22.8 versus 30.6h, P<0.001.

Comment: Not as good as a formal cost effectiveness analysis, which is sorely missing for this technology.
