Postoperative Delirium in Elderly Patients with Osteoarthritis Surgery: Incidence and Risk Factors

Abstract

Purpose:The purpose of this study was to evaluate the incidence of postoperative delirium in elderly patients with osteoarthritis surgery and identify risk factors for its development. Methods: This study enrolled 288 patients who underwent osteoarthritis surgery in a hospital between May and November 2014. Data were collected prospectively. The Nursing Delirium Screening Scale was used to detect delirium. Multivariable logistic regression analysis was used to identify independent risk factors for postoperative delirium. Patients were also followed for outcome. Results: Postoperative delirium developed in 42 patients (14.6%). Logistic regression analysis identified old age, low physical activity, antipsychotic agents, number of catheters, and intensive care unit admission as risk factors. Worse outcomes, including increased hospital mortality, reoperation, and discharge at care facilities, occurred in subjects who developed delirium. Conclusion: Osteoarthritis surgery in elderly patients was associated with a high incidence of postoperative delirium. The results of the this study regarding patient populations vulnerable to delirium should be taken into account so that such patients could be identified preoperatively or in the immediate postoperative period.

The Usefulness of Present-on-Admission Data as an Indicator of Healthcare Quality Evaluation Using the Korean National Hospital Discharge in-Depth Injury Survey Data from 2006 to 2019

“…This is attributable to the fact that these conditions are caused by chronic diseases prevalent among older adults, 35 and delirium is a common postoperative complication in older patients. 36,37 Therefore, intensive care with varying management timing is needed for older adults depending on their POA indicator. Furthermore, the rate of death was higher among patients with decubitus ulcers than those with delirium or hypokalemia.…”

“…This is similar to previous results, which show that delirium is more common in postoperative older adult patients and that femoral fracture is a common type of fracture among older adults. 37,51,52 Prompt treatment is crucial to prevent or minimize the adverse consequences of postoperative delirium, which is a form of cerebral dysfunction that occurs postoperatively. 53 Therefore, delirium is an important target disease for POA management and is a useful patient safety and healthcare quality indicator, especially for older adult surgical patients.…”
