Objective: To estimate whether the topical, amino acid-buffered hypochlorite debriding gel ChloraSolv (RLS Global AB, Sweden) could potentially afford the UK's health services a cost-effective intervention for hard-to-heal venous leg ulcers (VLUs). Method: A Markov model representing the management of hard-to-heal VLUs with ChloraSolv plus standard care (SC) or SC alone was populated with inputs from an indirect comparison of two propensity score-matched cohorts. The model estimated the relative cost-effectiveness of ChloraSolv in terms of the incremental cost per quality-adjusted life year (QALY) gained at 2021/2022 prices. Results: Addition of ChloraSolv to an SC protocol was found to increase the probability of healing by 36% (from 0.14 to 0.19) after 12 weeks, and by 79% (from 0.24 to 0.43) after 24 weeks. This led to a marginal increase in health-related quality of life. Treatment with ChloraSolv plus SC instead of SC alone reduced the total cost of wound management by 8% (£189 per VLU) at 12 weeks and by 18% (£796 per VLU) at 24 weeks. Use of ChloraSolv was estimated to improve health outcomes at reduced cost. Sensitivity analysis showed that use of ChloraSolv plus SC remained a cost-effective treatment with plausible variations in costs and effectiveness. Conclusion: Within the limitations of the study, the addition of ChloraSolv to an SC protocol potentially affords a cost-effective treatment to the UK's health services for managing hard-to-heal VLUs.
