Abstract

Introduction

Type 2 diabetes disproportionately affects Indigenous Māori in New Zealand. The reasons for this are multifactorial but include a history of colonialism, barriers to health care access and a lack of culturally appropriate interactions/relationships with health care providers. There is currently a need to develop models of health care delivery that are tailored to the needs of this population.

Aim

This pilot study evaluates the use of technology, education and culturally-informed wrap-around care (including medication optimisation) to improve type 2 diabetes biomarkers and self-management in a high-needs, majority Indigenous population.

Methods

Twenty-three participants with HbA1c >80 mmol/L received 2–4 weeks of continuous glucose monitor (CGM) wear at baseline and at 3 months alongside culturally-informed type 2 diabetes education and clinical care. Clinical biomarkers and psychometric measures were recorded at 0, 3, 6 and 12 months and 0 and 3 months respectively. Medication changes were recorded throughout the study.

Results

Mean (± s.d.) HbA1c significantly decreased from 93.4 ± 15.7 mmol/mol at baseline to 76.5 ± 14.8 mmol/mol at 3 months, with reductions maintained at 6 and 12 months by approximately three-quarters of participants (all P < 0.001 vs baseline). Diabetes self-management and LDL-cholesterol measures also improved significantly at 3 and 12 months, respectively.

Discussion

CGM informed, culturally-appropriate care has the potential to lead to sustained improvements in glycaemia in high-risk, Indigenous populations managed in primary care.
