Summary
A minimum data set (MDS) was established for total joint arthroplasty (TJA) registries, standardizing data collection for knee and hip replacements. This TJA-MDS improves patient care, research, and policy by enabling interoperable data across healthcare systems.
Area of Science:
- Orthopedics
- Health Informatics
- Biostatistics
Background:
- Total joint arthroplasties (TJAs), including total knee (TKA) and total hip (THA), are crucial for managing end-stage arthritis.
- Existing TJA registries are vital for monitoring implant performance, complications, and outcomes, but lack standardized data collection.
- Lack of standardization hinders data integration, interoperability, and comparative analysis across healthcare systems.
Purpose of the Study:
- To establish a minimum data set (MDS) for developing a standardized total joint arthroplasty (TJA) registry system.
- To define essential data elements for consistent capture of key TJA procedure information.
- To facilitate agreement among stakeholders and support patient care, clinical research, and policy decisions.
Main Methods:
- A mixed-method approach combining literature review, analysis of existing registries and medical records.
- Expert panel refinement of identified data elements using a two-round Delphi survey (17 experts).
- Inclusion of data elements with ≥80% expert agreement, validated using CVI, Kappa, and CVR.
Main Results:
- An initial 154 data elements were identified through literature review for TJA procedures (TKA and THA).
- Expert consensus led to the acceptance of 136 elements covering preoperative, intraoperative, and postoperative data.
- A final 111 data elements were confirmed for the TJA minimum data set (TJA-MDS) based on validity assessments.
Conclusions:
- The finalized TJA-MDS enables standardized, interoperable data collection across diverse healthcare settings.
- The TJA-MDS supports improved outcome monitoring, implant performance evaluation, and complication identification.
- This standardized approach facilitates evidence-based decision-making, multicenter research, quality improvement, and healthcare policy development for TJAs.
