Underestimated factors may also precipitate delirium and can lead to the misinterpretation of frailty in these patients

Birkan İlhan, Fatih Tufan, Gülistan Bahat, Mehmet Akif Karan Division of Geriatrics, Department ofInternal Medicine, Istanbul Faculty of Medicine, Istanbul University, Istanbul, TurkeyWe have read the article entitled "Association between frailty and delirium in older adult patients discharged from hospital" by Verloo et al1 with great interest. In their study, the authors observed that frailty is strongly associated with delirium in older patients at hospital discharge. Consequently, they concluded that assessing frailty gives health care professionals the opportunity to improve the effectiveness of primary prevention strategies for delirium, by promptly ascertaining which discharged older adults are at a higher risk of presenting with that syndrome.View original paper by Verloo et al
