Conclusion

The authors conclude that the use of PRP for the treatment of skin ulcers is cost effective; the extra cost for achieving the healing of 1 more ulcer than with usual care would be €364, much lower than the overall long-term costs of treating an ulcer with the usual approach of standard care without PRP (€5133).
