These researchers analysed outcomes of a chronic care management programme for diabetes, implemented in 2005 by a Primary Health Organisation. The cohort included 1311 people with diabetes (354 Māori, 957 non-Māori). At the start of the programme, HbA1c levels were higher in Māori than non-Māori (mean 8.1% vs 7.1%) but over the approximate 2-year follow-up, HbA1c for Māori improved to that of non-Māori. LDL-cholesterol and systolic blood pressure decreased during the programme in both groups. Improved glucose in Māori was not due to starting insulin or metformin, and rates of sulphonylurea prescription increased in both groups. Urinary albumin:creatinine ratio remained higher for Māori throughout the programme. Smoking rates and body mass index (both higher in Māori) did not change.
