This study aimed to develop a cost-effectiveness model to evaluate the feasibility of denture cleaning strategies for preventing denture stomatitis from the perspective of denture wearers in the United Kingdom. The model identified and estimated the costs and effects associated with three denture cleaning strategies. Results showed the total costs and incremental cost-effectiveness ratios, highlighting the lack of evidence on the relative effectiveness of different cleaning strategies and the need for further research.
Statement of problem. Denture stomatitis is a prevalent condition in denture wearers. Economic evaluations of health care can help stakeholders, including patients, make better decisions about treatments for a given condition. Economic models to assess the costs and benefits of different options for managing denture stomatitis are lacking. Purpose. The purpose of this study was to explore the feasibility of developing a cost-effectiveness model to assess denture cleaning strategies aimed at preventing denture stomatitis from a denture-wearer perspective in the United Kingdom. Material and methods. A model was developed to identify and estimate the costs and effects associated with 3 denture cleaning strategies. These were low care (LC)-cleaning by brushing and soaking overnight in water; medium care (MC)-brushing with toothpaste and soaking overnight in water; and optimum care (OC)-brushing and soaking overnight in water and antimicrobial denture cleanser. Costs, outcome measures (denture stomatitis-free days), and probabilities (incidence of stomatitis, unscheduled dentist visits, prescription charges, self-medication) associated with each strategy were defined. A sensitivity analysis was used to identify key drivers and test the robustness of the model. Results. The model showed that the total costs for 2015 ranged from (sic)1.07 (LC) to (sic)18.42 (OC). Costs associated with LC were derived from unscheduled dentist visits and use of medication and/or prescription charges. Incremental costs per denture stomatitis-free day were (sic)0.64 (MC) and (sic)1.81 (OC) compared with LC. A sensitivity analysis showed that varying either or both key parameters (baseline incidence of denture stomatitis and relative effectiveness of MC and OC strategies) had a substantial effect. Incremental cost-effectiveness ratios ranged from (sic)4.11 to (sic)7.39 (worst-case scenario) and from (sic)0.21 to (sic)0.61 (best-case scenario). Conclusions. A model was developed to assess the relative cost-effectiveness of different denture cleaning strategies to help improve denture hygiene. An important finding of the study was the lack of evidence on the relative effectiveness of different cleaning strategies, meaning that several assumptions had to be incorporated into the model. The model output would therefore likely be considerably improved and more robust if these evidence gaps were filled.
