The EQ-5D-3L is a validated generic measure instrument for patients health status which was developed in 1990 by the EuroQol Group. It consists of two components: the EQ-5D descriptive system represents a tool of 5 questions assessing mobility, self-care, usual activities, pain\/discomfort and anxiety\/depression meanwhile a visual analogue scale measures the general health state. It has already been used in many studies assessing general quality of life of several patient groups. The field of application of the EQ-5D includes various medical disciplines, including studies from orthopedics, oncology, geriatrics and cardiology. Compared to it’s extension – the EQ-5D-5L – the 3 level version showed weaknesses in form of ceiling effects and less informativity.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The EQ-5D-3L represents a generic measure instrument for patients health status and is not a disease-specific tool.1<\/a>, 2<\/a><\/sup> The instrument can be used for diseases in various medical disciplines.3<\/sup><\/a> There are studies in orthopedics that are exemplarily including patient groups with fragility fractures and spondyloarthritis, oncologic studies with cancer patients, cardiologic patient groups with heart failure and validation studies with elderly patients in general.4<\/a>, 5<\/a>, 6<\/a><\/sup><\/sub><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

The tool can be divided in two parts: on the one hand the EQ-5D descriptive system consisting of 5 questions with 3 response options each. Only one answer can be selected per question. The second part is the EQ-VAS, a visual analogue scale with an numeric equivalent from 0-100.<\/p>

The EQ-5D descriptive system consists of five dimensions: mobility, self-care, usual activities, pain\/discomfort and anxiety\/depression. Additionally the visual analogue scale assesses patients general health state with 100 as the best and 0 as the worst imaginable health state. The patient should answer the questions depending how he or she is feeling today.<\/p>

There is no information in literature about how long it takes to answer the EQ-5D-3L, but a short completion time can be expected due to the low number of items. We estimate a completion time of approximately 2-3min.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Scoring method<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Each of the five dimensions can be answered by picking one of three health levels: level 1 is connected with no problems, level two is linked with some problems and level 3 depicts extreme problems in the certain dimension. After answering all five items a unique health state <\/strong>is defined by combining the levels of each dimension in number, for example 11223. There is a total number of 243 possible health states (35<\/sup>). Missing values are coded as “9”. The score of the EQ-VAS is stated separately as a number (for example 73). A missing value in the VAS is coded as “999”.<\/p>

Out of the unique health state a single summary index can be generated by using a general population based value-set, where a score of 1 indicates the best possible health state whereas lower scores are linked with health deficits and scores <0 can be interpreted as “worse than sudden death”. The scoring concept bases on the time-trade-off method (patients have to decide how many years of symptom-free-life they would equal to 10 years of lifetime in the particular health state).7<\/sup><\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Patients health status can be represented with EQ-5D-single-summary-index<\/strong> and VAS-score<\/strong>. A single summary index of 1 is coding the best possible health score. Lower scores are connected with health status deficits.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
