医療における人工知能：「予測」から「患者中心の意思決定インテリジェンス」へ

The integration of artificial intelligence (AI) in healthcare is rapidly progressing from diagnostic support to predictive analytics. However, most existing clinical AI systems remain limited to generating predictions without translating them into individualised, actionable decisions for patients. This abstract highlights the need for transitioning from predictive AI models to patient-centric decision intelligence, which contextualizes multimodal patient data to support personalized clinical decision-making. Conventional AI models rely primarily on structured data and image-based inputs. In reality, patient care is influenced by diverse variables, including free-text clinical notes, voice biomarkers, wearable sensor output, social determinants of health, environmental exposures, and physician reasoning. Multimodal deep learning platforms integrating these heterogeneous data streams can deliver context-aware recommendations, reduce diagnostic delays, and support dynamic, individualized treatment plans. Moving toward Decision-Intelligence Healthcare Systems (DIHS) would enable explainable risk stratification, adaptive therapeutics, and real-time bedside guidance. Ethical imperatives-algorithmic transparency, dataset diversity, secure interoperability, and shared clinical accountability must guide deployment to ensure equity and physician trust. The next evolution of AI in medicine lies in decision intelligence, where algorithms function as ethical, explainable, and context-sensitive clinical thinking partners. Such systems can advance precision medicine, particularly in low-resource settings, by improving the quality of care, reducing error rates, and supporting equitable access to personalized treatment.
