The impact of a fracture liaison service for patients with femoral fractures on subsequent fractures and mortality: focusing on systematic literature review and metaanalysis

Abstract

Summary

The purpose of this study is to scientifically and systematically investigate the clinical effectiveness of a fracture liaison service (FLS) for patients with femoral fractures.

Methods

The international databases Ovid-MEDLINE, EMBASE, and The Cochrane Library and the Korean databases KISS, RISS, KoreaScience, Koreamed, and Kmbase were used. Risk of bias assessment was conducted at the study design level, and meta-analysis utilized both random-effects and fixed-effects models, along with subgroup analysis.

Results

From the 32 selected articles, 14 articles related to subsequent fracture and 18 articles related to mortality were included in the meta-analysis. As a result of the meta-analysis, the risk of subsequent fracture in the group that participated in the fracture liaison service was 46% lower than that in the non-participated group, and this difference was statistically significant (RR = 0.54, 95% CI = 0.50–0.59). The risk of death in the group that participated in the FLS was 17% lower than that in the non-participating group, and this difference was not statistically significant as well (RR = 0.83, 95% CI = 0.67–1.03). As a result of subgroup analysis, there was a statistically significant difference in the reduction of subsequent fracture in the clinical outcomes, and there was a significant difference in mortality in the intervention follow-up period and clinical outcomes.

Conclusion

The global implementation of FLS has played a crucial role in enhancing the clinical management and treatment of patients with femoral fractures, contributing to a decrease in subsequent fracture and mortality. This indicates the significant role of FLS in minimizing the disease burden associated with femoral fractures worldwide.
