Introduction and objectives: Diabetic foot is one of the disabling complications
of diabetes affecting more than one million people in Portugal. Negative pressure
therapy is relatively recent, describing itself as facilitating wound bed preparation
and inducing granulation and angiogenesis. It is our goal to provide an overview of
available evidence on the clinical efficacy of negative pressure in the treatment of
diabetic foot in adults.
Methodology: This is an umbrella review, with research in Scopus, Web of Science
and Ebsco (Cinahl Complete and Medline), with the time limit (2014-2019), English
and Spanish language, after defining the PICO review question, descriptors and inclusion
and exclusion criteria. Two investigators performed methodological quality
assessment, independently using JBI Critical Assessment Instrument.
Results and discussion: 14 systematic reviews were identified, 3 were duplicated,
9 were eliminated after application of the inclusion criteria. Two articles were
included, one with meta-analysis. The reviews included 23 studies indicating
that negative pressure therapy is effective and safe, generally reflecting greater
amounts of granulation tissue and shorter healing time. The existence of few
randomized controlled trials and small samples are some of the limitations mentioned.
Conclusions: The availability of evidence synthesized with this review may support
clinical decision-making leading to an improvement in the quality of health
care provided to people with diabetic foot injury.info:eu-repo/semantics/publishedVersio
