Increasing use of negative pressure wound therapy (NPWT) for thetreatment of acute and chronic wounds was observed in the last decade.

To assess the clinical eectiveness of NPWT for dierentwound etiologies in comparison with other conventionaltherapies.

Systematic reviews (SRs) and randomized controlled trials (RCTs) on NPWTwere retrieved in Pubmed, Embase and the Cochrane Library (until August2009). Grey literature was also searched. Primary endpoints wereincidence of complete wound healing and time to wound closure (Table 1).Article selection, quality assessment, data extraction and synthesis weredone independently by two authors ( Figure 1).

CLINICAL EFFECTIVENESS OF NEGATIVE PRESSURE THERAPYFOR WOUND HEALING: A SYSTEMATIC REVIEW

Well designed studies are needed to

assess NPWT eectiveness and safety in

the management of acute and chronicwounds. Although this technology is

broadly used in healthcare settings, high

quality data could allow the development

of good clinical practices.
