Oh yes and in response to people who say is already being used like enlightened and stealth
What is Care.data?
Care.data is an NHS England initiative to take data from your GP records and upload them to the national Health and Social Care Information Centre (HSCIC) databases. The aim at least nominally is to combine this with existing hospital records in the HSCIC database to provide a picture of the care being delivered between different parts of the healthcare system and to identify areas where more work or investment might be needed. The NHS says that Care.data will help find more effective ways of preventing or managing illness; monitor the risk of disease spread; streamline inefficiencies and drive economic growth. The data will be updated each month and will be taken automatically from every patient in England, unless you explicitly opt out.
Didn't this already happen?
No. For the last few decades the NHS Information Centre has collected patient data from hospitals, which it has used to identify, for example, the problems within the Mid Staffordshire Trust. The HSCIC was created by the Health and Social Care Act 2012 in preparation for this data gathering, and launched in April 2013. The same data has not been collected from GPs. Until now.
What are the potential benefits of using this data?
From a research point of view, this data could be enormously valuable. Not having access to this data means that the NHS is, in some cases, allocating resources blindly, not knowing with accuracy where gaps in healthcare provision are occurring. Moreover, the datasets could provide an incredibly useful resource for third-party researchers investigating the effectiveness of certain drugs, giving them access to enormous samples and an ongoing stream of data.
Is it that big a deal if it's already happening with hospital data?
Most people visit hospital much less frequently than they do their GP. GPs will generally have someone's lifetime of conditions, prescriptions, family history, blood tests and referrals. It's a much, much richer dataset.
