Purpose: To study patterns and predictors of medication use and laboratory monitoring in gout. Methods: In a cohort of veterans with a diagnosis of gout prescribed allopurinol, colchicine or probenecid, quality of care was assessed by examining adherence to the following evidence-based recommendations: (1) whether patients starting a new allopurinol prescription (a) received continuous allopurinol, (b) received colchicine prophylaxis, (c) achieved the target uric acid level of (6 mg/dl; and (2) whether doses were adjusted for renal insufficiency. The association of sociodemographic characteristics, healthcare utilisation and comorbidity with the recommendations was examined by logistic/Poisson regression. Results: Of the 643 patients with gout receiving a new allopurinol prescription, 297 (46%) received continuous allopurinol, 66 (10%) received colchicine prophylaxis and 126 (20%) reached the target uric acid level of (6 mg/ dl. During episodes of renal insufficiency, appropriate dose reduction/discontinuation of probenecid was done in 24/ 31 episodes (77%) and of colchicine in 36/52 episodes (69%). Multivariable regression showed that higher outpatient utilisation, more rheumatology care and lower comorbidity were associated with better quality of care; more rheumatology clinic or primary care visits were associated with less frequent allopurinol discontinuation; more total outpatient visit days or most frequent visits to a rheumatology clinic were associated with a higher likelihood of receiving colchicine prophylaxis; and a lower Charlson Comorbidity Index or more outpatient visit days were associated with higher odds of reaching the target uric acid level of (6 mg/dl. Conclusions: Important variations were found in patterns of medication use and monitoring in patients with gout with suboptimal care. A concerted effort is needed to improve the overall care of gout.
