ROI Calculation Logic

This technology could mitigate extended hospital stays and additional treatments due to adverse reactions. For instance, if adverse reaction-related hospital stays are shortened by an average of 5 days, an annual medical cost reduction of ~$2,000 per patient (AI est.) is projected. Applied to 500 patients annually: 500 patients × ~$2,000/patient = ~$1.0M annual medical cost reduction (AI est.).

Speed to Market
6× faster than in-house development
This technology's conditional probability calculation algorithm is already established, and its implementation primarily involves software and information processing devices, making integration into existing medical systems relatively straightforward. Developing a similar system from scratch would require at least 3 years for algorithm R&D, data collection, and validation. However, adopting this technology could shorten development by approximately 2.5 years, enabling market entry in about 6 months.
