Why and how do we measure frailty?
In the present issue of Internal and Emergency Medicine, Gullón et al.  report the results of an interesting observational study aimed at evaluating the prescription patterns of anticoagulants in a sample of older persons with non-valvular atrial fibrillation. In particular, the authors are interested in exploring the influence that the frailty condition (defined using the FRAIL scale ) may have on the therapeutic choices. The study confirms that frailty is highly prevalent in the hospital setting, and clearly represents a risk condition for negative health-related outcomes (in particular, in-hospital and 1-year mortality). Nevertheless, it seems that frailty does not represent a predictor of anticoagulant prescription, whereas functional impairment (captured by the Barthel Index) does.
The article raises important points worth a discussion. The present results are consistent with a large body of evidence documenting the association of frailty with negative health-related...
