The use of Negative Pressure Wound Therapy (NPWT) for acute and chronic wounds is widely accepted, and its use has been growing outside the hospital setting. The aim of this comparative effectiveness study was to evaluate the total cost to treat and total wound-related costs for patients initiating durable NPWT in the outpatient setting.

Our evaluation of claims data by Optum LifeSciences included patients with an initial NPWT claim between January 2016 and September 2018 . Patients were divided into two cohorts defined by brand of NPWT, NPWT-K* and NPWT-O. The cohorts were propensity score matched based on age, gender, comorbidities, and payor type. Claims data were used to define wound type and wound-related costs. Costs were evaluated and compared for the two cohorts at 30 days, 3 months and 12 months after initial NPWT placement. Each cohort included 3,368 patients after matching. At 30 days post initial NPWT, wound-related costs were $8,583 and $11,334 for NPWT-K and NPWT-O respectively (p

This comparative cost effectiveness analysis indicates a difference remains in wound related and total cost to treat for patients who receive durable NPWT in the outpatient setting.
