We compared the Modified Frailty Index and Hopkins Frailty Score for predicting duration of hospitalization.1  Johnson et al.2  and Darvall et al.3  note that the scores we used differ from those recommended by the 2012 frailty operative definition consensus conference.4  The consensus conference used a modified Delphi process to consolidate expert opinion and generate a consensus definition for frailty. Although participating experts agreed that frailty is multidimensional, they could not agree on an operational definition, possibly because supportive data for individual frailty components are lacking. The assessment tools we used assess single—but different—frailty dimensions. In this respect, they were similar to most perioperative frailty assessment tools that are also unidimensional. For example, a recent systematic review of reported frailty instruments describes 51 tools, of which only two are multidimensional.5
