I recently made A Freedom of Information requests to the NHS as listed here http://www.mage-net.net/2012/12/07/freedomofinformation
Yesterday () I got the results (I warn you they are shocking)!
A) how many people are employed by the NHS as a whole including Dr,GPs, and support/office staff?
Answer: 1,350377 (a lot)

B) how many of the above staff are physically disabled?
Answer: This is a little more complex. ESR does not distinguish between disability so this information is not available. However they do have data on Disabled staff.
Disabled Medical Staff: 632 or 1%
Disabled Non-Medical Staff: 23858 or 2%
