Cost-effectiveness of using a collagen-containing dressing plus compression therapy in non-healing venous leg ulcers.

OBJECTIVE: To estimate whether collagen-containing dressings could potentially afford the UK's National Health Service (NHS) a cost-effective intervention for the management of non-healing venous leg ulcers (VLUs).

METHOD: This was a modelling study performed from the perspective of the UK's NHS. A combination of published clinical outcomes, resource utilisation estimates and utilities for VLUs enabled the construction of a decision model, depicting the management of a chronic VLU with standard care or with a collagen-containing dressing plus compression therapy followed by standard care, over a period of 6 months. The model estimated the incremental cost-effectiveness of the two interventions in terms of the incremental cost per quality-adjusted life year (QALY) gained at 2015/16 prices.

RESULTS: The treatment of VLUs of >6 months' duration with a collagen-containing dressing plus compression therapy followed by standard care, instead of standard care, is expected to increase the probability of healing from 0.11 to 0.49 by 6 months and increase health-related quality of life at 6 months from 0.331 to 0.373 QALYs per patient. Additionally, treatment with a collagen-containing dressing plus compression therapy followed by standard care has the potential to reduce management costs by 40% over 6 months when compared with standard care (from £6328 to £3789 per patient).

CONCLUSION: Within the study's limitations, including a collagen-containing dressing into a standard care protocol compared with standard care potentially affords the NHS a cost-effective (dominant) treatment since it improves outcomes for less cost.
