Having worked in a company dealing with NHS data, it is amazing at how bad the quality of data is. Each and every visit/treatment is coded electronically by a band of people, to form spells and episodes. It is amazing at how many males actually give birth, as an example of rubbish data.
When my doctor cannot communicate electronically, using the internet, with a hospital less than 8 miles away, then you know there's a fundamental problem. (The communication which does take place is via fax machine of all things.) This is a Northamptonshire based doctor, sending me to a Warwickshire based trust. Both being referred and the results, had to travel across the good old telephone lines!
