The Karnofsky scale (sometimes called the Karnofsky index)
was devised by two American doctors in the 1940s (David Karnofsky
and Joseph Burchenal) as an attempt to try and measure the
more 'subjective' side of the outcome of cancer treatment.
In fact the scale relates purely to physical ability and
covers 11 points, from normal health to death, each scored
as a percentage. The scale is:
| Normal health |
100% |
| Minor symptoms |
90% |
| Normal activity with some effort
|
80% |
| Unable to carry on normal activity
but able to care for oneself |
70% |
| Requires occasional help with
personal needs |
60% |
| Disabled |
50% |
| Requires considerable assistance
and medical care |
40% |
| Severely disabled, in hospital
|
30% |
| Very sick, active support needed
|
20% |
| Moribund |
10% |
| Death |
0 |
