Although evidence exists which supports the positive effects of NPWT on take of skin grafts and flaps, there is limited evidence in relation to single-use systems such as PICO. Most previous studies have used traditional NPWT systems as part of their design. Though the technical applications of the traditional and newer single-use systems are comparable it is possible that some of the features of the latter may influence clinical outcomes. In addition to the limitations highlighted above, the cited studies have seldom assessed the ease of management and acceptability of NPWT systems. Although clinical outcomes may be considered paramount, these usability factors could also play a key role in ensuring compliance with negative pressure protocols.~Although evidence exists which supports the positive effects of NPWT on take of skin grafts and flaps, there is limited evidence in relation to single-use systems such as PICO.

S & N also wish to collect PMCF data in the indications of knee and abdominal incisions in order to make retrospective comparisons with data previously collected for these indications.~The aim of this study is therefore to assess whether the PICO 7 system is a safe and effective therapy for surgically closed incisions, skin grafts and flaps. Effectiveness will be defined by the ability of the system to deliver negative pressure and handle exudate and by percentage of successful skin graft or flap survival at Day 14.~A summary of known and potential risks and benefits to humans of each test article can be found in the Instructions for Use of PICO 7.
