Comparison of cost of wound management (£) using a four week silver treatment compared with non-silver treatment in primary care.

*Based on linear extrapolation of wound closure during first 4 weeks observed in the meta-analysis [22].
**Unit cost of initial assessment/follow up (From Table 1: £103.47 initial assessment + £84.04 follow-up visit + £29.95 ABPI assessment + £5.50 Duplex scan (10% of patients assumed to be referred to duplex scan)).
***Total healing time was assumed equal to average time to healing in patients with non-expanding wound estimated in the meta-analysis (minimum of healing time estimated for silver treatment respectively non-silver treatment arm). The split between weeks with complicated wound and normally healing wound was equal in both silver treatment and non-silver treatment arms.
†High frequency dressing change (4 times/week).
‡Low frequency dressing change (2 times/week).
