The Japanese government is teaming up with businesses and academia to set up hospitals enhanced by artificial intelligence, seeking to allow short-handed doctors to spend more time on patient care while curbing medical spending. The government is expected to invest more than $100 million in the effort over half a decade, with a target of establishing 10 model hospitals by the end of fiscal 2022. AI will help with tasks from updating patients' charts to analyzing tests and parsing images to help with diagnoses. The effort aims to address structural challenges to health care, including the chronic lack of doctors and nurses in some areas and rising medical expenses. The initiative will also help make Japan more competitive on the world stage, giving AI development a shot in the arm and helping boost exports of medical equipment. Three ministries central to the effort -- the education, industry and health ministries -- will recruit participating companies and hospitals this month, targeting AI specialists and medical equipment makers.
