How to Create an Orthopaedic Arthroplasty Database Project: A Step-by-Step Guide Part II: Study Execution.

Area of Science:

• Orthopaedic Surgery
• Health Services Research
• Biostatistics

Background:

• National database studies are increasingly prevalent in orthopaedic surgery research, particularly for lower extremity arthroplasty.
• These studies constitute approximately 10% of all published research in this field.
• A need exists for standardized guidelines to ensure the quality and reproducibility of such research.

Approach:

• This review provides a comprehensive guide for designing, executing, and publishing orthopaedic database arthroplasty projects.
• It details data collection strategies, including baseline demographics and outcome measures.
• The review proposes a novel checklist, Standards for Presenting Orthopaedic Database information (SOPOD), tailored for orthopaedic research.

Key Points:

• SOPOD builds upon existing EQUATOR network standards for observational studies, offering an orthopaedic-specific framework.
• Various statistical methods are discussed for data analysis, comparing demographics and outcomes while mitigating Type I errors.
• Key limitations of database studies, such as retrospective design and coding issues, are addressed.

Conclusions:

• This paper serves as a foundational resource for researchers conducting lower extremity arthroplasty database studies.
• Adherence to standardized reporting, like SOPOD, can improve the quality and impact of database research.
• Understanding and addressing the limitations inherent in database studies is crucial for accurate interpretation and reporting.
