Effect of negative pressure wound therapy with instillation and dwell time on health care utilization and costs in South Africa.

Although this study had limitations, including a potential selection bias, study data suggest that NPWTi-d may reduce wound-related health care utilization and costs for some patients through decreases in visits for subacute care. More studies are needed to fully assess how NPWTi-d affects wound care pathways, patient outcomes, and costs in South Africa.
