Health-Related Quality of Life and Functional Ability of Patients with Rheumatoid Arthritis- A Study from a Tertiary Care Hospital in Thailand



To assess the health-related quality of life and functional ability of patients with rheumatoid arthritis (RA) using the Thai EuroQol five-dimensional questionnaire (EQ-5D) and the Thai Health Assessment Questionnaire (HAQ), and to analyze correlations between the scores from both questionnaires.


This cross-sectional study was conducted among 221 patients with RA aged 18 years or older at a tertiary care hospital in Thailand. Data collection methods included individual patient interviews and data gathering from medical records. The correlations between the EQ-5D and HAQ scores were analyzed using Spearman’s rank correlation coefficients.


Most patients were female (78.3%), aged 41 to 60 years (57.0%), having had RA for 12 to 60 months (43.0%), and being in an active disease state (60.6%). From the EQ-5D, most patients reported no problems in each dimension, except for mobility and pain/discomfort. For the HAQ, most patients reported no difficulty for almost all activities, except for arising. The medians (interquartile ranges) for the EQ-5D utility, EuroQol visual analogue scale (EQ VAS), and HAQ scores were 0.65 (0.55–0.73), 70 (50–80), and 0.25 (0.00–0.81), respectively. The Spearman’s rank correlation coefficients were 0.42 for the EQ-5D utility and EQ VAS scores (P = 0.01), −0.65 for the EQ-5D utility and HAQ scores (P 0.001).


The health-related quality of life and functional ability of most patients in our study were partially affected by the disease. The EQ-5D and HAQ scores significantly correlated at a moderate to strong level.
