The ECOG score describes a patient’s level of functioning in terms of their ability to care for themself, daily activity, and physical ability (walking, working, etc.).
The scale was developed by the Eastern Cooperative Oncology Group (ECOG) and published in 1982; it is also called the WHO or Zubrod score and runs from 0 to 5, with 0 denoting perfect health and 5 death.
0 – Asymptomatic. Fully active, able to carry on all predisease activities without restriction
1 – Symptomatic but completely ambulatory. Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature (e.g., light housework, office work).
2 – Symptomatic, <50% in bed during the day. Ambulatory and capable of all self-care but unable to carry out any work activities. Up and about more than 50% of waking hours.
3 – Symptomatic, >50% in bed, but not bedbound. Capable of only limited self-care, confined to bed or chair 50% or more of waking hours.
