New Zealand Electronic Health Data for Cardiovascular Research: A Review

Area of Science:

• Health Informatics
• Cardiovascular Epidemiology
• Public Health Data Science

Background:

• Aotearoa New Zealand leverages individual-level, linked electronic health data for cardiovascular research.
• A robust health data infrastructure supports large-scale registry-based studies, including observational research and pragmatic clinical trials.

Purpose of the Study:

• To review the scope and utility of New Zealand's electronic health data for cardiovascular research.
• To assess demographic and epidemiological trends of cardiovascular disease in New Zealand.
• To compare New Zealand's data assets with international counterparts (Nordic countries, UK).

Main Methods:

• Analysis of nationwide administrative registries, clinical quality registries, and researcher-initiated registries.
• Evaluation of data coverage, content, linkage capabilities, and quality.
• Exploration of exemplar applications and ethical, legal, and infrastructural considerations.

Main Results:

• New Zealand's health data sources provide comprehensive information on healthcare services, clinical practice, and social determinants.
• Linkable registries, particularly researcher-initiated cohorts, show high utility for observational studies, clinical trials, and risk modeling.
• The health data infrastructure shows potential for international cardiovascular research collaborations.

Conclusions:

• New Zealand's electronic health data are a valuable resource for cardiovascular research.
• The data support both observational studies and clinical trials, advancing cardiovascular science.
