Clinical Report: Bibliometric Analysis of Frailty and Surgical Outcomes

Overview

This bibliometric study analyzed 4,119 publications on perioperative frailty from 1978 to 2024, revealing an exponential growth in research interest, especially since 2009. The data highlight frailty as a critical prognostic marker for adverse surgical outcomes and underscore the global research contributions across 95 countries.

Background

Frailty is a multifaceted syndrome characterized by decreased physiological reserves and increased vulnerability to stressors, commonly seen in the elderly. It encompasses physical, mental, and cognitive domains and is associated with higher risks of postoperative complications, prolonged hospital stays, and mortality. Preoperative frailty assessment has emerged as an essential tool for predicting surgical risk and guiding clinical decision-making. Despite growing recognition, the mechanisms linking frailty to surgical outcomes remain incompletely understood.

Data Highlights

Key Findings

• Research on perioperative frailty has increased exponentially since 2009, with a 40-fold rise in publications by 2023 compared to 2009.
• Frailty is a significant predictor of adverse surgical outcomes including postoperative complications, prolonged hospitalization, and mortality.
• Global contributions to frailty research span 95 countries, involving over 21,000 authors and nearly 1,000 journals.
• Bibliometric tools identified key research trends, influential authors, and thematic clusters, emphasizing the interdisciplinary nature of frailty studies.
• Preoperative frailty assessment is increasingly recognized as essential for risk stratification and optimizing perioperative care.

Clinical Implications

Clinicians should incorporate frailty assessments into preoperative evaluations to better predict surgical risks and tailor perioperative management. Awareness of frailty's impact on outcomes can guide interventions aimed at improving recovery and reducing complications. The expanding research base supports ongoing development of standardized frailty measures and targeted strategies in surgical populations.

Conclusion

The bibliometric analysis underscores frailty as a pivotal factor influencing surgical outcomes and highlights the rapid growth of research in this field. Enhanced understanding and integration of frailty assessments into clinical practice are vital for improving perioperative care and patient prognosis.
