Venous ulcer care: which dressings are cost effective?

Healed or open venous ulcers may be present in up to 1% of Western populations and consume a large amount of healthcare resources. These ulcers are characterized by a chronic inflammatory environment with impaired healing and often require months for closure. The average monthly cost of care for an open ulcer has been estimated to be $4095. The fundamental tenets of ulcer care include adequate compression and maintaining a moist wound environment with an appropriate primary dressing. A number of specialized products including semi-occlusive/occlusive, antimicrobial, and advanced wound matrix dressings are now available. However, there is little data from appropriate clinical studies to suggest significantly improved outcomes with any of these dressings. Data regarding their cost-effectiveness is also limited, often conflicting, and subject to bias. At present, there is little solid evidence to guide the choice of primary dressings and a patient-centered approach focusing on characteristics of both the patient and their ulcer, while paying attention to costs, may be most appropriate.
