Audio-Recorded Messages Delivered Via iPad to Prevent Delirium in Hip Fracture Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

Audio-Recorded Reorientation Intervention: Participants in this arm receive personalized audio-recorded reorientation messages delivered three times daily during the first three post-operative days. Each message lasts approximately 2 minutes and contains personalized information including the current location, date and time, and encouraging messages. Messages are delivered via iPad and headphones by nursing staff during routine care. Audio messages are available in English, Mandarin, Malay, and Tamil to accommodate patient language preferences. Participants also receive all standard post-operative care and treatments.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Protocol Adherence Rate — Postoperative day 1 to postoperative day 3
  Percentage of planned audio-recorded reorientation sessions successfully delivered by the nurses across the first 3-day intervention period. Target adherence rate ≥95% to demonstrate intervention feasibility.
• Recruitment Feasibility — From enrollment to end of study participation (up to 2 weeks)
  Recruitment feasibility measured by screening-to-enrollment rate, calculated as: (1) percentage of screened patients meeting eligibility criteria, and (2) percentage of eligible patients providing informed consent. These rates will be tracked throughout the study period to assess the feasibility of recruiting the target population for a future definitive trial. Target enrollment rate of ≥80% of eligible patients will indicate feasibility.
• Study Retention Rate — From enrollment to end of study participation (up to 2 weeks)
  Percentage of enrolled participants who completed the study protocol without withdrawal, calculated as number completing study divided by total enrolled. Target retention rate ≥90% to demonstrate intervention feasibility.
• Intervention Tolerance Rate — Postoperative Day 1 to Postoperative Day 3
  Completion of each audio-recorded reorientation session without early discontinuation or adverse reactions, assessed during each of the 9 planned sessions per participant. Target adherence rate ≥95% to demonstrate intervention feasibility.
