This indicator shows the number and percent of people with diabetes dispensed insulin regularly. Regular use was defined as insulin dispensed in three or more quarters in a year.
Understanding the reasons behind variations in insulin is important as it can give some insights into differences in the quality of care received by people with diabetes. It helps to develop strategies that promote effective diabetes management, ensure equitable access to insulin therapy when needed, and enhance patient outcomes. Some reasons for variation in insulin usage include diabetes type, patient acceptance, adherence, and physician preferences.
People with diabetes dispensed insulin in three or four quarters in the relevant year.

Disaggregation
For single map analysis: By year (2018‒22), age group (0‒14 years, 15‒24 years, 25‒44 years, 45‒64 years, 65‒74 years and 75+ years), gender (female and male), ethnic group (Māori, Pacific peoples, Indian and European/other) and Health New Zealand district of domicile.
For PHO analysis: By year (2022), age group (0‒14 years, 15‒24 years, 25‒44 years, 45‒64 years, 65‒74 years and 75+ years), gender (female and male), ethnic group (Māori, Pacific peoples, Indian and European/other), PHO most recently enrolled with (for the relevant year), PHO group (small, medium, medium‒large and large).
- Data is not presented where the number of people in the numerator was less than 10. This is to preserve confidentiality.
- Ethnicity data presented is prioritised ethnic group (Māori, Pacific peoples, Indian and European/other).
- For all indicators, individuals with missing values for any of the variables of interest (age, gender, ethnicity and district) are excluded completely. For instance, if there are any missing values for age, they are excluded from all analyses. This approach ensures a consistent denominator throughout the analyses.
- Demographic information is taken from the VDR.
