Hypothesis
The validity of frailty indices (FIs) varies across different international data sources.
Conclusion
Frailty indices show varying prevalence rates depending on their development context, which may limit their validity in international studies.
Supporting Evidence
- The VAFI identified higher prevalence of frailty in US databases compared to the eFI.
- The eFI identified higher prevalence in UK databases compared to the VAFI.
- Frailty prevalence rates varied significantly between the two indices.
Takeaway
This study looked at how different ways of measuring frailty in older people can give different results depending on where the data comes from.
Methodology
Comparison of frailty prevalence using two validated electronic health record based FIs across five databases.
Limitations
The external validity of frailty indices may be limited due to their dependence on the context of development.
Participant Demographics
Patients aged 40+ years with at least one year of data.
