3.3 Performance status
Patient performance status is a central factor in cancer care and should be clearly documented in the patient’s medical record.
Performance status should be measured and recorded using an established scale such as the Karnofsky scale or the Eastern Cooperative Oncology Group (ECOG) scale.
Consideration should be given to frailty and the patient’s functional state. Consider referral to other disciplines such as geriatrics or endocrinology if appropriate.
