“…Additionally, one study had a longer follow-up period, with mortality at 24 and 48 months of 26% and 40% in patients without delirium and of 36% and 60% in patients with delirium during hospitalization after a fracture [31]. the predictors identified in this systematic review were grouped into 1) demographic factors: older age [14,17,[20][21][22][23]33,34] and male sex [14,17,33]; 2) clinical factors: comorbidities [15,16,18,20,23,31], high scoring in surgical risk assessment scores [13,17,21,24,33,34,38], functional status before fracture [17,31,33,36], and cognitive/neurological disorders [15,23,31,39]; and 3) intra-hospital factors: infections [15,21,23,26,30] and the time between hospitalization and surgery [20,21,34,35]. Only one study addressed prolonged hospitalization as a factor associated with mortality [16] (S1Table).…”
