Development of cut-off scores for symptom screening with the EORTC quality of life scales

Whilst clinicians and health care professionals may understand the significance of, for example, a Hb value of 9.0 and know that a clinical intervention is required, it may not be so obvious what a fatigue score of 35 indicates and whether this is abnormally low and requires attention.

In this research stud,y patients complete a QLQ-C30 and answer some additional questions about whether a symptom has been a burden, limited their daily activities or meant they have needed additional help and care.

A patient will be considered to have a symptom of moderate relevance, if they report at least one of the following: “moderate burden”, “mild limitations”, or the need for “a little help from family and friends”.

A patient will be considered to have a symptom of high relevance, if they report at least one of the following: “severe burden”, at least “moderate limitations”, or at least the need for “quite a bit of help from family and friends”.

A symptom rated as being only a mild burden, posing no limitations to daily activities and not requiring any help will not be considered relevant. Using a statistical technique called AOC it will be possible to determine threshold scores for each symptom of moderate and high relevance.
