I'm a member of an organisation called useMydata - a group of patients keen on having their medical data shared across different bits of the NHS. So that GPs, consultants, ambulance crews can find out about you.
Our organisation is having a conference on the subject of health data sharing for our own care and for research, this June, In Leeds.
My Leukaemia data is spread around different parts of the NHS; 2 GP surgeries, 3 hospitals. No researcher would ever find the whole progression of my Chronic lymphocytic leukaemia (CLL).
Check it out on our website: usemydata.org/content_db.ph...
And even if you can't come think about joining useMydata - we're doing some useful stuff providing patient representatives to all sorts of organisations within and outside the NHS.
