Google\u2019s\u00a0reach into almost all aspects of people\u2019s digital lives \u2013 from email and search, to maps and calendars \u2013 means there isn\u2019t much it doesn\u2019t know about its 1.17 billion users. And now, the technology giant might even know when you\u2019re going to die.\r\nThe company\u2019s Medical Brain team is using a new type of artificial intelligence algorithm to make predictions about the likelihood of death among hospital patients.\r\nA paper published last month in the journal\u00a0Nature\u00a0detailed how its predictive algorithm used vast data sets to determine whether inpatients will survive in two different hospitals.\r\nFor predicting inpatient mortality, Google\u2019s Medical Brain was 95 per cent accurate in the first hospital and 93 per cent accurate in the second hospital.\r\n\u201cThis was significantly more accurate than the traditional predictive model,\u201d\u00a0the paper\u00a0stated. \u201cThese models outperformed traditional, clinically-used predictive models in all cases. We believe that this approach can be used to create accurate and scalable predictions for a variety of clinical scenarios.\u201d\r\nIn one case study, the Medical Brain algorithm gave a woman with metastatic breast cancer a 19.9 per cent chance of dying in the hospital by crunching 175,639 data points from her medical records.\u00a0\r\nThe hospital's Early Warning Score\u00a0that it typically uses gave her a 9.3 per cent chance of dying. Within two weeks the patient was dead.\r\nGoogle has already made inroads into the medical industry with its DeepMind\u00a0subsidiary \u2013 considered by some academics to be\u00a0the leaders in artificial intelligence research.\r\nIt has already courted controversy, however, after it was revealed in 2013 that DeepMind had access to\u00a01.6 million medical records of NHS patientsat three hospitals run by London's Royal Free Trust.\u00a0\r\nA leaked letter from\u00a0Dame Fiona Caldicott, the head of the Department of Health's National Data Guardian, questioned the\u00a0access deal by suggesting it may be have been made on an "inappropriate legal basis."
