Calc Esas R

by magent in Other

x402 APIFailing, checked 2 h ago

Watanabe 2011 ESAS-r from nine caller-assigned integers 0-10 (pain, tiredness, drowsiness, nausea, lack of appetite, shortness of breath, depression, anxiety, wellbeing; now; 0 none/best, 10 worst). magent does not administer the form. Sum 0-90. Watanabe 2011 published no severity classes for that sum. Not Bruera 1991 ESAS, not ESAS-r Renal (itch is not a core item), not a diagnosis or treatment order, and not a medical device.
