Abstract:
AIM: To examine whether there was variation in markers for the quality of gout care using national linked data for the entire Aotearoa New Zealand population. METHOD: Data drawn for the New Zealand Atlas of Healthcare Variation was used to examine regularity of allopurinol dispensing, laboratory testing for serum urate, and acute hospitalisation for gout. Standardised rates by age, gender, ethnicity and District Health Board (DHB) of domicile were calculated. RESULTS: For New Zealanders aged 20-79 years with gout, 57% were dispensed allopurinol in 2010/11. Of these, 69% were receiving allopurinol regularly, and only 34% of people dispensed allopurinol had serum urate testing in a 6-month period. The annual hospitalisation rate was 1% of people with gout. Maori and Pacific people with gout were less likely to be on regular allopurinol treatment, despite having more than twice the chance of being hospitalised with acute gout. CONCLUSION: We have demonstrated that routinely collected health data can be used to monitor the quality of care for people with gout at a high level. Primary care initiatives that focus on ensuring a continuous supply of urate-lowering therapy to achieve therapeutic serum urate targets are required to improve the impact of gout in Aotearoa New Zealand.
