Abstract
BACKGROUND

Intensive care unit (ICU)-hospitalized patients have a high risk of developing delirium; however, the related diagnosis and treatment remain inadequate.

AIM

To clarify the preventive effect of evidence-based, non-pharmacological care bundles on delirium in ICU-hospitalized patients.

METHODS

A total of 149 ICU patients (May 2022-May 2025) were enrolled, including 72 patients in the control group receiving routine nursing and 77 patients in the research group receiving evidence-based, non-pharmacological care bundles. Comparative analyses were conducted regarding delirium occurrence (incidence, time of first occurrence, and duration), nursing complications (deep venous thrombosis, ventilator-associated pneumonia, and unplanned extubation), clinical indices (mechanical ventilation duration, ICU length of stay, hospitalization time, and sedative duration), cognitive function (Chinese version of the Johns Hopkins Adapted Cognitive Exam), sleep quality (Richards-Campbell Sleep Questionnaire), sedation level (Richmond Agitation and Sedation Scale), health status (Acute Physiology and Chronic Health Evaluation II), anxiety and depression (Hamilton Anxiety Scale/Hamilton Depression Scale), and nursing satisfaction.

RESULTS

Compared with the controls, the research group showed lower delirium incidence, fewer overall nursing complications, and shorter time of first delirium occurrence, delirium duration, mechanical ventilation duration, ICU stay, and hospitalization time. The research group also demonstrated reduced sedative and analgesic dosages; lower Richmond Agitation and Sedation Scale, Acute Physiology and Chronic Health Evaluation II, Hamilton Anxiety Scale, and Hamilton Depression Scale scores; and higher post-interventional Adapted Cognitive Exam and Richards-Campbell Sleep Questionnaire scores, as well as higher overall nursing satisfaction.

CONCLUSION

Evidence-based, non-pharmacological care bundles are highly effective in preventing delirium in ICU-hospitalized patients.

Keywords: Evidence-based; Non-pharmacological care bundles; Intensive care unit; Delirium; Preventive effect

Core Tip: This study aimed to optimize and strengthen delirium management in intensive care unit-hospitalized patients by implementing evidence-based, non-pharmacological care bundles. Through comprehensive analyses, this model was found to be effective in preventing delirium, reducing nursing-related complications, and accelerating recovery. It also significantly improved cognitive function, sleep quality, and overall health status. The intervention is both safe and effective, with profound clinical implications.
