abstract={<b>  </b><b>Background:</b> Sleep disruption is strongly linked to delirium, a common and serious complication in ICU patients, associated with longer hospital length of stays, higher mortality, and long-term cognitive decline. Sleep bundle interventions are multifaceted strategies designed to enhance sleep quality and reduce the risk of delirium in intensive care units (ICUs). <b>Purpose:</b> This study aimed to evaluate the effectiveness of a sleep bundle intervention to promote sleep quality and reduce incidence rate of delirium among critically ill patients. Setting: Medical, Surgical, and Anesthesia ICUs in a tertiary care hospital. Sample: A convenience sample of 120 critically ill patients.<b> </b><b>Design:</b> Quasi-experimental design. <b>Instruments:</b> Demographic and clinical data sheet; Sleep Quality Scale Index; Richards-Campbell Sleep Questionnaire; Intensive Care Delirium Screening Checklist (ICDSC); Confusion Assessment Method for the ICU (CAM-ICU); and APACHE II scale. <b>Results:</b> the intervention group showed significantly better sleep quality (31.78 ¡À 13.86) compared with the control group (54.38 ¡À 10.93) (p &lt; 0.001). The incidence of delirium was significantly lower in the intervention group (0.33 ¡À 0.91) than the control group (0.83 ¡À 1.29) post-intervention (p = 0.03). The ICU length of stay was significantly shorter in the intervention group (4.15 ¡À 1.27 days) compared with the control group (4.75 ¡À 1.64 days; p &lt; 0.05). There was a significant positive correlation between severity of illness and delirium incidence rate in the study group (r = 0.619, p &lt; 0.001) and the control group (r = 0.689, p &lt; 0.001). Co-morbidities also correlated positively with delirium in the study group (r = 0.375, p &lt; 0.001) and control groups (r = 0.617, p &lt; 0.001). <b>Conclusion:</b> Sleep bundle intervention effectively improved sleep quality, reduced delirium incidence rate, and shortened ICU length of stay among critically ill patients. <b>Recommendation:</b> Integrating sleep bundle intervention into routine ICU care is recommended to enhance clinical outcomes among critically ill patients.},
