Summary
Same-day discharge total joint arthroplasty research is rapidly expanding globally. Future studies should focus on diverse healthcare models, international collaboration, and robust trial designs for continued growth.
Area of Science:
- Orthopedic Surgery
- Health Services Research
- Bibliometrics
Background:
- Same-day discharge (SDD) total joint arthroplasty (TJA) is increasing globally, accelerated by the COVID-19 pandemic.
- Understanding research trends is crucial for advancing SDD TJA practices.
Purpose of the Study:
- To conduct a bibliometric analysis of publication trends, key contributors, and geographic distribution in SDD TJA research.
- To identify patterns and future directions in the field of SDD TJA.
Main Methods:
- Bibliometric analysis of studies on SDD TJA from the Web of Science Core Collection (inception to January 2025).
- Assessment of publication rates using compound annual growth rate (CAGR) and segmented regression.
- Tabulation of top authors, institutions, countries, and international collaboration prevalence.
Main Results:
- 121 studies published between 2014-2024, with a 44% CAGR.
- Significant publication increase observed post-2023 (19 publications/year vs. 2.1/year pre-2023).
- Majority of studies (53%) originated from the USA, with limited international collaboration (5.8%).
Conclusions:
- SDD TJA research demonstrates substantial and accelerating growth.
- Future research should prioritize diverse healthcare models, international collaborations, and methodologically rigorous randomized controlled trials.
