Overview

The main objective of this research will be to investigate whether the control of care provided by the family/caregiver can prevent the onset of delirium in individuals undergoing surgical intervention for hip fracture.

The research will be a randomized, single-blind, parallel, two-arm clinical trial that compares two conditions: intervention group, hereafter IG (Delirium Zero protocol based on a space-temporal orientation poster for the patient, a clock hung on the wall next to the orientation poster, and a checklist for the preventive measures taken by the caregiver/family), and control group, hereafter CG (standard of care).

The participants will be patients over 65 years old, admitted to the trauma hospitalization units of the La Fe University and Polytechnic Hospital (La Fe Health Department, Valencia, Spain), operated on for hip fracture and accompanied by a relative/caregiver.

The research will be carried out at the La Fe University and Polytechnic Hospital (La Fe Health Department, Valencia, Spain) because it is the reference hospital for the Valencian Community, and because the rooms in this center are private, which allows for no interference between the intervention under study (in GI) or the standard care (GC).
