A randomized, controlled trial (RCT) published in 2019 describes the PICO single-use negative pressure wound therapy (sNPWT) system as an effective treatment option for chronic wounds.1 The study showed that wounds treated with the PICO sNPWT healed twice as fast as those treated with traditional negative pressure wound therapy (tNPWT). Wound closure rates were 45% and 22% in the groups of patients treated with sNPWT and tNPWT, respectively.
In addition, subsequent experimental studies describe the PICO sNPWT’s mode of action and show how it delivers this efficacy with the following three attributes:
In summary, the PICO sNPWT delivers undisturbed healing, provides a wider zone of therapy, and is a simple and portable system. All these attributes work together to deliver superior clinical outcomes. Primary health care nurses are encouraged to consider the PICO sNPWT as a first-choice option for the early intervention and treatment of chronic wounds.
