By Industry News

June 2, 2020 – Smith+Nephew, the global medical technology business, announced the publication of a health economic study in Wound Management and Prevention, which states that the use of PICO◊ Single Use Negative Pressure Wound Therapy System (sNPWT) is estimated to be highly cost effective when compared with traditional NPWT (tNPWT), and may therefore provide opportunity to reduce the economic burden of venous leg ulcers (VLUs) and diabetic foot ulcers (DFUs).1

Expected cost savings per patient of using PICO sNPWT vs tNPWT were $18,504 for DFUs and $14,113 for VLUs at week 26.1

The study results are being released at the outset of the Wound, Ostomy and Continence Nurses Society annual conference, WOCNext 2020, being held online.

The economic model used data from a multicenter, randomized, controlled trial (RCT) to estimate wound closure rates.*2 The study demonstrated superior clinical outcomes of PICO sNPWT vs. tNPWT in the management of patients with lower extremity ulcers with a longer than four weeks duration over 12 weeks.†2 In an economic model, for both ulcer types combined, switching from tNPWT to PICO sNPWT resulted in an expected cost saving per patient of $15,749 and 5.31 open ulcer weeks per patient over 26 weeks, and a 31% increase in percentage of expected closed ulcers.1

In the United States alone, chronic wounds affect 6 million people, with increasing numbers anticipated in growing elderly and diabetic populations.3 One study showed that DFUs alone are estimated to cost the US health system between $9 to $13 billion.4

“Tools that decrease skyrocketing health care costs and improve patient’s quality of life are always needed for wound care patients. The novel and inventive technology of the PICO system does both,” said Dr. Cyaandi Dove D.P.M., co-author of the 2019 RCT.

PICO sNPWT's evidence base consists of137 published papers of which 26 are published RCTs and health economic evaluations, and 79 are unique clinical studies.5

For detailed product information including indications for use, contraindications, precautions and warnings please consult the product’s applicable Instructions for Use (IFU) prior to use. In the United States PICO 7 sNPWT is not indicated for use with compression therapy.
