Passage 1 人工智能和数字技术·医疗保健中 AI 的变革潜力
Artificial intelligence (AI) is generating excitement everywhere, but in the field of health care it has the potential to be transformational. In Europe analysts predict that AI could save hundreds of thousands of lives each year.
There is already evidence that AI systems can enhance diagnostic accuracy and disease tracking, im - prove the prediction of patients' outcomes and suggest better treatments. It can also boost efficiency in hospitals and surgeries. It may already be reducing the time it takes for new drugs to reach clinical trials. New tools, including generative AI, could supercharge these abilities. Yet as our research this week shows, although AI has been used in health care for many years, integration has been slow and the results have often been mediocre.
There are good and bad reasons for this. The good reasons are that health care demands high eviden - tial barriers when introducing new tools, to protect patients' safety. The bad reasons involve data, regula - tion and motivations. Overcoming them could hold lessons for AI in other fields.
AI systems learn by processing huge volumes of data, something health - care providers have in abun - dance. But health data is highly fragmented; strict rules control its use. Governments recognize that pa - tients want their medical privacy protected. But patients also want better and more personalized care. Each year roughly 800, 000 Americans suffer from poor medical decision - making.
Improving accuracy and reducing bias in AI tools requires them to be trained on large data sets that reflect patients' full diversity. Finding secure ways to allow health data to move more freely would help. But it could benefit patients, too: they should be given the right to access their own records in a portable, digital format. Consumer - health firms are already making use of data from wearable devices, with varying success. Portable patients' records would let people make fuller use of their data and take more responsi - bility for their health.
