KT
If you want to work it out / estimate it yourself, you could apply a
scaling factor to the patient's surface area calculation (normally
height squared).
If the management of burns a "rule of ninths" applied when estimating
the surface area affected by the burn.
Each arm is 1/9
Each leg is 2/9
The trunk is 2/9
The head is 1/9
At what level were the amputations?
For bilateral above-knee amputations (with most of the thigh
remaining) one might reasonably assume that the surgeon has taken a
total of 2/9 of the patient's surface area and adjust the denominator
of the BMI calculation accordingly.
For the purpose of collecting a QOF point of two, it probably only has
to be reasonable, not right. Who is going to have a better method
during the annual QOF visit?
Your own eyeballed estimate of his adiposity is of course worth rather
more in the real world where doctors treat patients rather than fields
in templates.
