Development and validation of reporting guidelines for studies involving data linkage.

Area of Science:

• Health Services Research
• Biostatistics
• Epidemiology

Background:

• Data or record linkage is crucial for creating comprehensive datasets for research.
• Inaccurate data linkage can compromise study quality and introduce errors.
• Clear and consistent reporting is essential for appraising the methodological quality of linked data studies.

Purpose of the Study:

• To develop and validate reporting guidelines for evaluating the methodological quality of studies that use linked data.
• To enhance the consistency and clarity of reporting in data linkage research.
• To provide a framework for readers to accurately interpret the quality of results from linked data studies.

Main Methods:

• A multi-stage development process involving a literature review, a Delphi process, and a validation process.
• Involved Australian experts including biostatisticians, epidemiologists, registry administrators, academic clinicians, and a journal editor.
• Systematic approach to ensure comprehensive and expert-driven guideline development.

Main Results:

• Developed a set of guidelines comprising four domains and 14 reporting items.
• Guidelines cover critical areas: data sources (6 items), research variables (4 items), linkage technology and data analysis (3 items), and ethics, privacy, and data security (1 item).
• The structured guidelines provide specific criteria for reporting.

Conclusions:

• This study represents the first development of guidelines specifically for appraising the quality of reported data linkage studies.
• The guidelines are expected to significantly assist authors in reporting their findings consistently and with high quality.
• These reporting guidelines will empower readers to better interpret the quality and reliability of results derived from data linkage research.
