ROI Calculation Logic

Assuming a 10% reduction in re-operation rates or prolonged hospital stays due to postoperative adhesion. For a hospital performing 1,000 relevant surgeries annually, with an additional medical cost of ~$3,500 (AI est.) per adhesion-related complication, an annual medical cost reduction of ~$350K (1,000 cases × 10% reduction × ~$3,500) is estimated. Including material cost reductions from manufacturing process efficiencies, the total economic impact could reach ~$650K annually (AI est.).
