Performance Status Assessment by Using ECOG (Eastern Cooperative Oncology Group) Score for Cancer Patients by Oncology Healthcare Professionals
Open accessAbstract
Medical literature does not have clear consensus on inter-rater reliability of PS assessment by different oncology health care professionals (HCPs) although it plays an important role in treatment decision and prognosis for oncology patients. Eastern Cooperative Oncology Group (ECOG) and Karnofsky performance status (KPS) scores are commonly used for this purpose by oncology HCPs around the world. This study was conducted to find variability or similarities in assessment of PS among the different oncology HCPs. A survey based on four hypothetical clinical scenarios was devised and sent to 50 oncology HCPs to assess the PS using ECOG PS tool. No significant variations in PS assessment by oncology HCPs was noted in our study sample.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
The ECOG scores range from 0 to 4, and higher scores indicate lower performance level.
“The ECOG globally evaluates patients’ performance, and it is scored between 0 and 4 points. Higher scores indicate lower performance level [20].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
