Questionnaire survey evaluating disease-related knowledge for 149 primary gout patients and 184 doctors in South China

This study aims to investigate the disease-related knowledge of gout patients and doctors in south China and to identify the important targets of education for patients and doctors. A cross-section survey of 154 primary gout patients and 185 doctors who may see gout patients was conducted with a modified questionnaire with ten items of gout-related knowledge. The participants were considered to have gout-related knowledge if he or she correctly answered seven or more items. One hundred and forty-nine valid questionnaires from patients, 33 from rheumatology physicians, and 151 from non-rheumatology doctors were collected for statistical analysis. The mean correctly answered items of three groups were 6.6 +/- 2.2, 9.6 +/- 0.53, and 8.0 +/- 1.4, with rate of being considered to have knowledge about gout 51.7, 100, and 90.1 %, respectively (P < 0.05). The correct answer rate for each particular item was over 80 % in the rheumatology physician group. Patients or non-rheumatology doctors knew the optimal serum uric acid (sUA) level (48.3 vs 55.6 %), the need to take lifelong urate-lowering drugs (29.5 vs 43.6 %), that allopurinol is a urate-lowering drug (55.7 vs 76.0 %), and how to prevent attacks induced by urate-lowering therapy (ULT) (60.4 vs 74.0 %). Logistic regression showed that higher education predicted which patients had gout-related knowledge. Both the gout patients and non-rheumatology doctors in south China had poor knowledge on ULT. Since many gout patients do not see rheumatologists, our data suggest that further education should focus on patients and non-rheumatologists and emphasize the use of urate-lowering drugs, treatment duration, the target sUA level, and prophylaxis against acute attacks.
