Abstract
Introduction
This analysis aims to provide an update of the Level-IV Partners Arthroplasty Registry (PAR), a quality-improvement initiative and research data repository.
Methods
The Harris Joint Registry was founded in 1969 and has since expanded to become the Partners Arthroplasty Registry (PAR). Today, the PAR captures data on total hip and total knee arthroplasties conducted at seven hospitals in Massachusetts. Over time, data has been sourced through independent collection at a single hospital, retrospective sourcing through the Research Patient Data Registry (RPDR), and currently through the Enterprise Data Warehouse (EDW). Various statistical methods analyzed changing trends of care provided to patients across affiliated institutions. PROMs collected in the PAR are the PROMIS Physical Function and Global Health Short Forms, the HOOS and KOOS. The registry is an associate member of ISAR and will incorporate the international implant library.
Results
The PAR contains demographic, implant-specifics, and radiographic data for 45,645 primary arthroplasties and 8,400 revision surgeries from 1998 to 2018. The average recorded Charlson Comorbidity Index is 0.98. Average length of stay prior to home or care facility discharge decreased from 5.00 days in 2001 to 3.00 days in 2018. The average 30-day and 90-day mortality rates for 2018 were 0. 18% and 0.28%, respectively. Home discharge increased from 30.1% to 79.0% from 2001–2018. The values for these parameters are varied across the seven sites.
Conclusion
The PAR can be used to develop best practices, analyze health-care economics, and promote evidence-based medicine. We are also developing a platform for registry development that can be exported by other hospitals that utilize an Epic-based record system.
