Summary
A new Belgian EQ-5D-5L value set was created using preferences from the general population. This tool aids healthcare evaluations and health assessments in Belgium.
Area of Science:
- Health Economics
- Psychometrics
- Population Health
Background:
- The EuroQol 5-Dimensions 5-Levels (EQ-5D-5L) instrument is widely used for health status measurement.
- A country-specific value set is crucial for accurate health economic evaluations.
- No existing EQ-5D-5L value set specifically reflects the preferences of the Belgian adult population.
Purpose of the Study:
- To establish a Belgian EQ-5D-5L value set.
- To derive values from the preferences of the adult Belgian general population.
- To support healthcare decision-making and health assessments in Belgium.
Main Methods:
- Utilized the EuroQol Valuation Technology (EQ-VT 2.1) protocol.
- Conducted computer-assisted personal interviews with a representative sample of 892 Belgian adults.
- Employed composite time trade-off (cTTO) and discrete choice experiment (DCE) methods to value health states.
Main Results:
- Developed a hybrid multiplicative eight-coefficient model using combined DCE and cTTO data.
- The resulting Belgian EQ-5D-5L value set ranges from -0.532 to 1.
- The dimensions of pain/discomfort and anxiety/depression resulted in the greatest loss of health-related quality of life.
Conclusions:
- Successfully developed a Belgian EQ-5D-5L value set reflecting general population preferences.
- The new value set is suitable for clinical and economic evaluations in Belgium.
- Facilitates accurate measurement of patient-reported outcomes and population health assessments.

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

2.1K
Measurement is an indispensable part of analytical chemistry. The result of measurement helps quantify a substance's physical property and compare it with the physical property of another substance. Each measurement comprises two components - a number indicating the magnitude and a unit of measurement as a standard for comparison. Further, the same quantity can be measured using different units of measurement, which leads to differences in magnitude.

00:56Nominal Level of Measurement
30.5K
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. Not every statistical operation can be used with every set of data. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
The data that cannot be measured but can be grouped into categories fall under the nominal level of measurement. Data that is measured using a nominal...

A percentile indicates the relative standing of a data value when data are sorted into numerical order from smallest to largest. It represents the percentages of data values that are less than or equal to the pth percentile. For example, 15% of data values are less than or equal to the 15th percentile.

00:55Interval Level of Measurement
16.0K
For effective statistical analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
Data measured using the interval scale are similar to ordinal level data because they have a definite arrangement. However, in the interval level of measurement, the differences between data values are meaningful even though the data does not have a starting point.
Temperature is measured using the interval scale. It is measurable data, and the difference between...
