The purpose of this study was to compare EQ-5D-5L and SF-6D as instruments to measure the quality of life of OA patients at RSAU dr. Efram Harsana Madiun. This study used a descriptive study using a cross-sectional design. Data collection was carried out by distributing the EQ-5D-5L and SF-6D instruments, then scoring was carried out.

The SF-6D questionnaire contains 6 domains, namely physical function, role limitations, social function, pain, mental health and vitality. The description of the quality of life of OA patients based on EQ-5D-5L shows that the main problem of patients is pain (100%) which has an impact on inhibiting walking ability (77.8%), while based on SF-6D the quality of life of OA patients also has a main problem in the form of pain (100%), which has an impact on physical function (67.8%), and role function (47.8%). The utility value of OA patients using EQ-5D-5L was 0.722 while SF-6D was 0.835. Sociodemographic factors that affect quality of life based on the EQ-5D-5L and SF-6D questionnaires are age, gender, location of OA, and comorbidities (p=<0.05).
