We read with interest the study by Sonny et al.1  assessing frailty using the Hopkins phenotypic scale and of the health deficit–based modified frailty index in 1,042 patients undergoing noncardiac surgery. We are particularly interested in the finding that neither approach to diagnosing frailty was a clinically useful predictor of unexpected prolonged hospital stay, readmission, and serious complications. We agree that many previous studies of frailty have not adequately examined both odds ratios and predictive value of frailty assessments. However, we are concerned about the validity of the modified frailty index as a tool to measure frailty. Sonny et al. found only a weak correlation between the modified frailty index and Hopkins frailty scales: r = 0.28.
