“…Four guidelines were focused on the management of patients with specific diseases, including diabetes, hemophilia, and cancer [ 33 , 34 , 35 , 36 ], and one focused on palliative care for older frail patients [ 37 ]. In terms of the setting, eight guidelines were specific for hospitals or nursing homes [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 34 ] and six for home care [ 30 , 31 , 32 , 33 , 35 , 36 ], while one recommendation was made for both settings [ 37 ]. With regards to the frailty index, four guidelines suggested to screen patients with the Clinical Frailty Scale [ 23 , 27 , 29 , 34 ], and one suggested the French Clinical Frailty Score or Frailty Group Iso-Resource Evaluation (FRAGIRE) score [ 26 ], while all the others did not specify any frailty index.…”
