Effect of noise isolation on postoperative delirium in elderly patients undergoing hip surgery: protocol for a randomised controlled trial.

ABSTRACT:

Introduction

Postoperative delirium (POD) is a frequent complication in elderly surgical patients, leading to increased morbidity and mortality. Previous studies have shown that noise isolation is associated with a reduced incidence of delirium in the intensive care unit (ICU). This trial aims to evaluate the impact of noise isolation using noise-cancelling headphones on the incidence of POD in elderly patients undergoing hip surgery.

Methods and analysis

In this randomised controlled trial, a total of 320 elderly patients will be randomised to a noise isolation group or a control group, in a 1:1 ratio and stratified by age (65‒80 years or >80 years), type of surgery (fracture or non-fracture) and planned ICU admission (yes or no). For patients in the noise isolation group,
