Do psychomotor subtypes and duration of postoperative delirium affect 6-month mortality in hip-fractured elderly patients?
Hypoactive and mixed postoperative delirium, as well as longer duration of delirium, are associated with increased 6-month mortality in elderly patients with hip fractures.
Hyperactive delirium was the most common POD psychomotor subtype, but hypoactive and mixed POD were associated with 6-month mortality risk. Moreover, the risk of death 6 months after surgery increased for both subgroups (hypoactive and mixed) with increasing duration of POD.
Bellelli et al. (Thu,) studied this question.
