According to a Wall Street Journal report, Google will have access to patient records from HCA, which operates 181 hospitals and more than 2,000 healthcare sites in 21 states. "HCA would consolidate and store with Google data from digital health records and internet-connected medical devices under the multi-year agreement," the report said on Wednesday. Google will store anonymised data from patient health records and internet-connected medical devices. That data will be used to build programmes that could inform medical decisions made by healthcare providers, the report mentioned. Not just Google, Microsoft and Amazon are also working in the field to analyse patient data and create such AI/ML-based programmes, to foray into the $3 trillion healthcare sector.
