Guide for use:Help on this term

The Eastern Cooperative Oncology Group (ECOG) performance score was developed to consistently assess the impact of a person's disease on their daily living abilities.

Record the ECOG performance status score recorded at diagnosis and before the implementation of treatment.

Performance status should be based on assessment by a clinician at the time of initial presentation.

Only record performance status when expressed as an ECOG score by the clinician; do not attempt to determine the ECOG score from patient notes.
Collection methods:Help on this termThis information should be obtained from the patient's medical record at the time of diagnosis. It may be available in the admission notes, outpatient notes or referral letters.
Comments:Help on this term

Performance status at diagnosis is an important prognostic indicator and is used to determine appropriate treatment, assess how the disease is progressing, and for the statistical analyses of outcome adjusted by performance status.

Previous attempts to collect this information has revealed that ECOG scores are not routinely recorded at the time of diagnosis. However, performance status is an important prognostic indicator and used to determine and evaluate treatment decisions so recording the ECOG score in patient notes at the time of diagnosis is strongly recommended.
