Distress screening using distress thermometer.

Sir,

The report on distress screening using distress thermometer is very interesting.[1] Lewis et al.,[1] concluded for “Positive correlation between distress score and pain score and occurrence of physical symptoms.” The concern is on distress thermometer. Chambers et al.,[2] reported that this tool was acceptable in case that “a cut-off of ≥4 may be optimal soon after diagnosis, and for longer-term assessments, ≥3 was supported.” The adjustment of the tool for each setting is needed. Martínez et al.,[3] noted that “the diagnostic accuracy of the DT could be improved with minor proposed modifications to the DT and the inclusion of nonemotional ultra short measures.” Second, the tool has to be modified in case that it was aiming at pediatric patients screening.[4]
