The Efficacy of Music in Preventing Delirium in Elderly Patients With Hip Fracture

The aim of this trial is to explore the efficacy of music in preventing delirium in elderly patients with hip fracture.

The main aims of this research are:

1. To compare the effectiveness of music intervention in preventing delirium in patients with hip fractures through a randomized controlled trial. The comparisons include respiratory rate, pulse rate, blood pressure, and pain score, as well as the incidence and severity of delirium, opioid analgesic usage, postoperative complications, length of hospital stay, and rates of readmission within 14 days and 30-day mortality.
2. Introduce the evidence-based ''listening music protocol'' in the care of hip fracture patients to prevent delirium, and test the effects through a randomized controlled trial.

This study is a two-group, pre and post-test, randomized controlled trial to test the effectiveness of the ''listening music protocol''. Convenience sampling will be used to select the inpatients with hip fractures in a regional hospital in southern Taiwan. 102 participants will be randomly assigned either to an experimental (n=51) or to a control (n=51) group. The experimental group will receive a six-day music protocol and regular post-operative care. The control group will receive regular post-operative care only. Statistical analysis was performed using SPSS Version 22.0.

Descriptive statistics, including frequencies, percentages, means, and medians, were used to analyze basic attributes. For the analysis of homogeneity, the chi-square test or Fisher's exact test was employed for categorical variables. The paired t-test was used to compare respiratory rate, pulse rate, blood pressure, and pain index.

Following the intervention, the occurrence and severity of delirium before and after implementing music intervention were compared. Additionally, comparisons were made for opioid analgesic usage, postoperative complications, length of hospital stay, and 30-day mortality.
