and anxiety/depression. Each attribute has three levels: no problem, some problems, and

major problems, thus defining 243 possible health states, to which have been added

‘unconscious’ and ‘dead’ for a total of 245 in all – EQ5D3L as it has three levels of choices in

each dimension. Correspondingly, another system has five levels per dimension called the
EQ5D5L. Both are supplemented with a VAS scale; a vertical 20 cm thermometer scoring from

zero (worst imaginable health state) to hundred (best imaginable health state). The

respondent rates their current health state on this EQ-VAS by drawing a line from the box
marked “your own health state today” (the bottom) upto the appropriate point or mark the

appropriate point with a cross/check mark.

This brings us to the conclusion of how to valuate various health outcomes and what

all to consider in the whole process of choosing, measuring and collecting data on the
requisite health outcome and parameter.
