Gout

The gout domain of the Atlas of Healthcare Variation provides information on gout by demographics, health district and primary health organisation (PHO).

About the data

The information in this domain includes an estimate of those likely to have gout (based on parameters from service use) and how their gout is managed. The data is not intended to form definitive statements of quality, rather to raise questions about potential areas for quality improvement.

Data for 2019–2024; released September 2026

What is gout

Gout is the most common form of inflammatory arthritis. It is caused by an inflammatory response to monosodium urate (MSU) crystals, which form in the presence of high urate concentrations. Patients typically present initially with recurrent flares of severe joint inflammation. Over time, the presence of elevated serum urate concentrations (hyperuricaemia) can lead to:

  • tophus formation
  • chronic gouty arthritis
  • progressive joint damage.

Long-term urate-lowering therapy is recommended for patients with recurrent gout flares (two or more per year), tophaceous gout and/or joint damage. Allopurinol is the first-line urate-lowering therapy drug in New Zealand, but when indicated, probenecid and febuxostat are also effective. Target serum urate of < 0.36 mmol/L is needed to dissolve MSU crystals, suppress gout flares and aid tophi regression. Gout flares can be treated with NSAIDs, colchicine or corticosteroids (Lindsay et al 2011; Martini et al 2012; Dalbeth et al 2013), and low-dose colchicine or corticosteroids are also recommended for initial introduction of urate-lowering therapy to prevent flares related to fluxes in serum urate concentration.

We encourage you to use the atlas data to understand disease burden and dispensing patterns in your region to ensure your patients are getting the best possible treatment for their condition.

What the data shows

Data is from 2019 to 2024 and can be viewed by age, gender and ethnic grouping. Variation by health district and PHO are also presented. We use indicators to show data; these indicators were developed with the help of an expert advisory group.

The methodology for some indicators has been updated in this edition of the atlas, including changes to look-back periods and case definitions. As a result, estimates may differ from those reported in previous editions and should not be directly compared. Please see methodology for more information.

For quality improvement purposes, the atlas presents observed (crude) rates. These rates reflect the actual experience of the population and support local service planning and improvement activities. However, when comparing ethnic groups to understand equity, we recommend using age-specific rates.

Selected findings from the atlas are summarised below. For all indicators and detailed commentary, see the atlas dashboards.

Key messages

  • In 2024, 6.3 percent of the PHO‑enrolled population aged 20 years or over were estimated to have gout.

  • Crude estimates for gout were higher for Pacific peoples and Māori than non-Māori non-Pacific peoples. For example, among those aged 20–44 years, crude estimates for Pacific peoples (7.9 percent) and Māori (4.4 percent) were about five times and three times higher respectively than the rate for non-Māori, non-Pacific (1.5 percent).

  • Young Pacific people (56 percent) and Māori (51.5 percent), aged 20–44 years, estimated with gout were more likely than non-Māori, non-Pacific (48.1 percent) to receive urate-lowering therapy at any time during the year. However, they were less likely to receive this therapy regularly (Māori: 20.6 percent; Pacific peoples: 21.5 percent; non-Māori non-Pacific peoples: 24.1 percent).

  • Younger people (20–44 years) with estimated gout, particularly Māori and Pacific peoples, were dispensed non-steroidal anti-inflammatory drugs (NSAIDs) at significantly higher rates than other groups with estimated gout.

  • Overall, 14 percent of people with estimated gout were dispensed NSAIDs at any time during the year but were not dispensed urate-lowering therapy. These rates varied by district, for example, ranging from 13.9 to 23.0 percent among those aged 20–44 years.

  • Overall, crude rates for hospital admission as a result of gout for Māori (1,286 per 100,000) and Pacific peoples (1,487 per 100,000) were nearly 2.5 times the rate for non-Māori, non-Pacific populations (513 per 100,000).

Data sources and methodology

A key change was made to the numerator calculation to more accurately capture people with gout. We have observed an increase in colchicine prescribing for conditions other than gout, such as pericarditis, other crystal arthropathies and periodic fever syndromes. To address this, we excluded individuals dispensed colchicine who had a relevant hospital record (based on the ICD diagnosis codes listed below) within the 2 years before the colchicine dispensing. This resulted in the exclusion of 4,836 people in 2024, representing approximately 2% of the cohort.

Excluded ICD diagnosis codes:

  •  I010 Acute rheumatic pericarditis
  • I092 Chronic rheumatic pericarditis
  • I300 Acute nonspecific idiopathic pericarditis
  • I301 Infective pericarditis
  • I308 Other forms of acute pericarditis
  • I309 Acute pericarditis, unspecified
  • I310 Chronic adhesive pericarditis
  • I311 Chronic constrictive pericarditis
  • I32 Pericarditis in diseases classified elsewhere
  •  I319 Diseases of pericardium, unspecified
  • M11 Other crystal arthropathies
  • E85.0 Non-neuropathic heredofamilial amyloidosis

 Another key change was the application of a 15-year rolling look-back period to identify prevalent gout cases for each reporting year. For example, for the 2024 reporting year, gout status was determined using data from 1 January 2010 to 31 December 2024.

Previously, the look-back period had a fixed start point of 1988 for hospital admissions and 2001 for dispensing gout-specific urate-lowering therapies (allopurinol, febuxostat, benzbromarone) or colchicine. As a result, the look-back period increased each year as the estimates were updated. Because the look-back period increased each year, estimates may have been influenced by the growing amount of historical data available rather than changes in the prevalence of gout. Moving to a fixed look-back period improves comparability between years, provides a more consistent case definition and makes trends over time easier to interpret.

In this update, we excluded a key quality indicator measuring serum urate testing within 6 months of urate‑lowering therapy dispensing (Dalbeth et al 2015) . This was due to incomplete coverage of the laboratory claims dataset in some districts, as well as the increasing use of point‑of‑care serum urate testing, which may not be captured in the laboratory claims collection. We recommend practitioners reflect on / audit where possible their own practice in relation to this indicator.

For each of the indicators in this atlas domain, it was not possible to assess whether:

  • the medicine was clinically indicated
  • the dose was optimal (including the recommended starting and maintenance dose of urate-lowering therapy)
  • anti-inflammatory prophylaxis was prescribed at the time of starting urate-lowering therapy
  • the medicine was taken.

Analyses by ethnicity used prioritised ethnicity, whereby individuals reporting multiple ethnicities were assigned to one ethnic group according to the standard Ministry of Health prioritisation order. This ensured ethnic groups were mutually exclusive and allowed comparisons between groups. We acknowledge that this method may underestimate results for Pacific peoples, as individuals who identify with both Pacific and Māori ethnicities are classified within the Māori group. We also acknowledge that Pacific peoples are not a homogenous population, comprising various communities with distinct languages, cultures and identities. For estimates for the total Pacific population or specific Pacific ethnic groups, please contact us at info@hqsc.govt.nz.

The Asian peoples grouping has been combined with the European/Other groups in the non-Māori, non-Pacific group in this atlas. This is because the overall estimated gout prevalence for Asian populations (3.7 percent) is lower than the European/Other population (5.6 percent), and in some districts, the small size of the Asian population means many results were suppressed. Middle Eastern, Latin American and African (MELAA) peoples has also been included in the European/Other grouping and hence non-Māori, non-Pacific group in this atlas.
