The cost-effectiveness of single-use negative pressure wound therapy (sNPWT)* compared to traditional NPWT (tNPWT) for the treatment of chronic lower-extremity ulcers
Lower extremity ulcers such as venous leg ulcers (VLU) and diabetic foot ulcers (DFU) have a major impact on quality of life and continue to impose a substantial cost burden on health care providers.1
An increase in long-term chronic disease and an aging population means that the prevalence of lower-extremity ulcers is likely to increase.1 At a time when health care costs are constrained, health care systems need to make the best use of resources in order to minimize the impact of these demographic changes.
One of the key drivers of cost is the time to heal the wound, and strategies to improve healing outcomes are therefore an important consideration.2
NPWT is known to be an effective treatment for these wound types, and the development of single use portable canisterless NPWT has provided smaller, lighter devices for patients and their caregivers.3
A recent 161-patient RCT demonstrated a significant reduction in wound closure at 12 weeks for sNPWT compared with tNPWT.
It is important to determine the relative cost-effectiveness of alternative therapies in order to support decision-makers and policy-makers in making the best treatment policy decisions. However the cost-effectiveness of sNPWT in direct comparison with tNPWT has not been investigated. Therefore it is of interest to determine whether sNPWT is likely to be more cost-effective than tNPWT for these wound types.
