Precision ICU Care: Evaluating an AI-Driven Nursing Decision Support System for Delirium Prevention

maanantai 1. kesäkuuta 2026 päivittänyt: Hsiao-Yean Chiu, Taipei Medical University

Efficacy of an Intelligent Computational Nursing Decision Support System in Precision Critical Care for Delirium Prevention: A Randomized Controlled Trial

Delirium affects up to 83% of mechanically ventilated patients in the Intensive Care Unit (ICU), often leading to longer hospital stays and long-term memory or cognitive problems. While standard care protocols (such as the ABCDEF bundle) exist, they are often difficult to implement fully due to their complexity and the heavy workload on nursing staff.

To address these challenges, this study introduces a 'Precision Nursing' approach by integrating Artificial Intelligence (AI) and Virtual Reality (VR). We will implement an AI-driven system to assist nurses in making personalized care decisions more efficiently. Additionally, interactive VR technology will be used to stimulate patients' cognitive function and encourage early mobility. Our goal is to reduce the clinical burden on healthcare providers while significantly improving recovery outcomes for ICU patients.

Yksityiskohtainen kuvaus

Delirium affects up to 83% of ventilated ICU patients, necessitating precise non-pharmacological interventions like the SCAN-D program, which aims to improve outcomes by integrating smart computing and virtual reality into nursing decisions. This three-year, assessor-blinded, parallel randomized controlled trial will enroll 188 patients, assigning them to either usual care or the SCAN-D group, where the latter receives personalized strategies based on machine learning risk weights, including family-supervised immersive VR exercise and cognitive training. Throughout their stay, patients will be monitored via shift-based assessments (ICDSC/RASS) and nightly sleep tracking using actigraphy combined with one-lead EEG, while long-term cognitive function and quality of life (EQ-5D-3L) will be evaluated at three and six months post-discharge. The primary outcomes are the incidence of delirium and delirium-free days within the first 28 days of ICU admission, measured using the ICU Delirium Screening Checklist. Secondary outcomes include sleep quality and quantity, functional status during the ICU stay, ICU length of stay, duration of mechanical ventilation, total hospital length of stay, ICU mortality rate, Sedative and Analgesic Loading, 90-day Mortality Post-discharge, cognitive function, and quality of life. Finally, the collected data will be analyzed using SPSS 22.0 through independent t-tests, Chi-square tests, and Generalized Estimating Equations (GEE) to determine the program's efficacy in reducing delirium incidence and enhancing overall patient recovery.

Aseet ja interventiot

Osallistujaryhmä / Arm
Interventio / Hoito
Kokeellinen: Smart Computing Assisted Nursing Decision in Delirium Prevention(SCAN-D) group
The algorithm will calculate variable weights and select features contributing to 80% of the risk. These variables will guide the implementation of personalized delirium prevention strategies, with making decision based on nurses' clinical expertise.
Laite: MLP-based Clinical Decision Support System (MLP-CDSS)
An AI-integrated system utilizing a Multilayer Perceptron (MLP) model to predict delirium risk and guide targeted interventions. The system continuously analyzes real-time data from Electronic Health Records (EHR), including physiological parameters, medication history, and laboratory results.
Käyttäytyminen: VR-based Cognitive Intervention
A virtual reality intervention designed to provide cognitive stimulation and reduce sensory deprivation. Patients engage in interactive games (e.g., traditional-themed tasks such as goldfish scooping or lantern festivals) that require attention, memory, and spatial orientation. These sessions are conducted twice daily for total 30-40 minutes, 3-4 times a week.
Käyttäytyminen: VR-assisted Early Mobility Exercise
A VR-based physical activity program focused on promoting upper limb movement and range of motion. The virtual environment encourages patients to perform specific gestures or reaching tasks while in bed or a seated position, aiming to improve mobility and reduce the physical deconditioning common in ICU stays. These sessions are conducted twice daily for total 30-40 minutes, 3-4 times a week.
Ei väliintuloa: routine care control group
The control group will receive routine care, including delirium assessments and sleep environment management.

Incidence of ICU delirium
Aikaikkuna: From ICU admission to ICU discharge or maximum 28 days, assessed per shift
The proportion of participants who develop delirium during their ICU stay. Delirium is assessed using the Intensive Care Delirium Screening Checklist (ICDSC). The checklist evaluates 8 clinical signs, with each item scored 0 or 1. A total score of 4 or higher is defined as a "positive" delirium diagnosis.
From ICU admission to ICU discharge or maximum 28 days, assessed per shift
Delirium-Free Days
Aikaikkuna: Through Day 28 after ICU admission.
The number of days alive and free of delirium during ICU stay. Delirium status is assessed daily using the Intensive Care Delirium Screening Checklist (ICDSC). A "delirium-free day" is defined as a calendar day on which the patient is alive and has an ICDSC score of less than 4

Toimenpiteen kuvaus
Aikaikkuna
Subjective Sleep Quality
Aikaikkuna: Daily from enrollment until ICU discharge or up to a maximum of 28 days.
