How population-level data linkage might impact on dental research

Area of Science:

• Dental Epidemiology
• Public Health
• Health Informatics

Background:

• Population-level data and record linkage present significant opportunities for dental epidemiology.
• Traditional studies often exclude marginalized groups, leading to biased results and human rights concerns.
• High-quality health record linkage systems exist globally, with Western Australia possessing unique, comprehensive population databases.

Purpose of the Study:

• To explore the potential of population-level data linkage for advancing dental epidemiology.
• To highlight the advantages of unbiased data collection and the inclusion of all population segments.
• To examine the application of data linkage in Western Australia for health research, including oral health.

Main Methods:

• Utilizing linked population databases in Western Australia, including birth, death, and hospital admission records since 1980.
• Linking health data with population databases to identify characteristics like intellectual disability and birth defects.
• Integrating Commonwealth and State data, including pharmaceutical benefits data for pharmacovigilance.

Main Results:

• The linkage of birth and hospital admission data with population databases allows for detailed analysis of specific health characteristics.
• Data linkage enables pharmacovigilance by connecting birth defect data with medication use during pregnancy.
• The development of similar data linkage systems in other Australian states suggests broader applications for oral health research.

Conclusions:

• Population-level data linkage provides unbiased, comprehensive data crucial for advancing dental epidemiology.
• The inclusion of all individuals, particularly marginalized groups, enhances the ethical and scientific integrity of health research.
• The expanding availability of data linkage in Australia holds significant promise for gaining deeper insights into oral health patterns and outcomes.
