A Value Set for EQ-5D-5L in the United Arab Emirates
Fatima Al Sayah1, Bram Roudijk2, Mohamed El Sadig3
1Center for Clinical, Health Economics and Outcomes Research (CCHO), Dubai, United Arab Emirates.
Summary
A new value set for the EQ-5D-5L was developed using preferences from the general adult population in the United Arab Emirates. This tool aids in assessing healthcare cost-effectiveness and population health.
Area of Science:
- Health Economics
- Psychometrics
- Population Health
Background:
- The EQ-5D-5L is a widely used instrument for measuring health status.
- Developing country-specific value sets is crucial for accurate health economic evaluations.
- No existing EQ-5D-5L value set represents the preferences of the United Arab Emirates (UAE) general adult population.
Purpose of the Study:
- To develop a value set for the EQ-5D-5L instrument tailored to the preferences of the UAE general adult population.
- To provide a tool for health technology assessment and population health studies within the UAE.
- To ensure culturally relevant and accurate health outcome measurements in the UAE.
Main Methods:
- The study adhered to the EuroQol EQ-5D-5L valuation protocol.
- Interviewer-administered face-to-face or online interviews were conducted with 1005 adults in Arabic or English.
- A 2-stage quota sampling strategy ensured representation across all 7 UAE emirates, including nationals and expatriates.
Main Results:
- A hybrid tobit model, censored at -1.0 and corrected for heteroskedasticity, was identified as the best performing model.
- Health state values ranged from -0.654 (worst health) to 1 (full health).
- Mobility problems demonstrated the most significant impact on health state preference values.
Conclusions:
- The developed EQ-5D-5L value set is suitable for use within the UAE population.
- This value set will enhance the accuracy of cost-effectiveness analyses for healthcare interventions in the UAE.
- It will also support broader applications in population health assessment and health system evaluations within the UAE.

01:11Secondary Healthcare System
1.4K
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.

01:29Assessment of the Gastrointestinal System II: Health Perception Pattern
72
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.

01:21Tertiary Healthcare System
1.7K
Specialized care provided over an extended period is called tertiary care. Usually, a primary or secondary care physician will refer a patient to tertiary care. A patient's maximum physical and mental function is restored in tertiary care, which is caused due to the impact of a chronic illness or condition. Tertiary care aims to achieve the highest level of functioning possible while managing chronic illness. For example, a patient who falls and fractures their hip will need secondary care...

00:55Interval Level of Measurement
14.2K
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...

01:26Traditional Level Of Health Care System
2.6K
The levels of care describe the services provided in the healthcare system. Accordingly, there are six levels of the traditional healthcare system in the US: preventive, primary, secondary, tertiary, restorative, and continuing healthcare. A nurse must understand how the healthcare industry organizes and provides services within these levels of care.
The preventive healthcare service includes tests for screening. Preventive health care services include identifying and reducing disease risk...
