estimated ROI · USD · AI analysis
ROI Calculation Logic

Considering annual medical costs for dysphagia (e.g., aspiration pneumonia treatment) and specialist rehabilitation/evaluation fees. Assuming aspiration pneumonia treatment costs ~$13.5K (AI est.) per case, and specialist evaluation/guidance costs ~$2.0K (AI est.) per person/year. This technology could reduce aspiration pneumonia risk by 5% and improve specialist evaluation resource efficiency by 20%. For 100,000 target patients, this translates to a potential market reduction of (~$13.5K × 100,000 × 0.05) + (~$2.0K × 100,000 × 0.20) = ~$50M + ~$40.0M = ~$90M (AI est.). From this, an annual economic impact of ~$10.0M (AI est.) could be generated.
