EuroQol EQ-5D-3L Quality of Life Population Norms for Sierra Leone
摘要
To provide population norms of the Health-Related Quality of Life (HRQoL) in Sierra Leone with the EuroQoL EQ-5D-3L. The norm score can be used to compare patients’ health status and development of their quality-of-life status during treatment.
MethodsEQ-5D-3L data was collected of 1894 respondents by face-to-face interviews, along with the Visual Analog Scale (VAS) score and demographic data including gender, age, work, ethnicity and country district. VAS scores, index scores (based on the Zimbabwe value set), sum scores, and distribution of levels per dimension were described and calculated. Statistical tests were performed to determine which demographic variable influenced the VAS and index scores.
ResultsThe mean VAS score (standard deviation (SD)) and index (SD) found were 82 (12) and 0.85 (0.09), respectively. No statistical difference was found in the VAS score for gender but in the index; with male and female mean index values of 0.84 and 0.86, respectively (p < 0.001). The best possible QoL index state was found in 59.4% of the respondents. The lowest possible QoL index was not encountered. The percentage of an unimpaired QoL in the dimensions were: mobility 92.0%; self-care 96.7%; usual activities 90.9%; pain/discomfort 68.3% and anxiety/depression 77.0%, respectively.
ConclusionThis study provides a population norm for Sierra Leone, which can be used to compare a patient’s HRQoL to the population’s norm, and to assess the effect of a treatment on the HRQoL.
