Delirium and Post-operative Cognitive Dysfunction (POCD)

The goal of this pilot clinical trial is to learn if personalized audio-recorded reorientation messages can be successfully implemented in general hospital wards for elderly patients after hip fracture surgery. It will also explore whether this intervention might help prevent confusion (delirium) after surgery. The main questions it aims to answer are: * Can the intervention be successfully delivered by nursing staff in a busy orthopedic ward? * How many eligible patients can be recruited and retained in the study? * Do patients tolerate listening to the personalized audio messages without problems? * Does listening to personalized audio messages show any early signs of reducing confusion after surgery? Researchers will compare patients who receive personalized audio messages to those who receive usual care to see if the intervention is feasible to implement and whether it shows promise for preventing delirium. Participants will: * Listen to 2-minute personalized audio-recorded reorientation messages played through an iPad and headphones three times daily for the first 3 days after surgery * Have their orientation and mental status checked daily for three times by nursing staff * Continue with all their regular medical care and treatments * Be monitored until discharge from the study wards.
