Poor sleep during hospitalization can negatively affect patient health, well-being, and satisfaction. This nurse-led quality improvement project aimed to promote quality sleep on an inpatient telemetry medical–surgical oncology unit. Interventions included distributing sleep hygiene kits (eye masks, earplugs, lip balm, and aromatherapy), educating patients and staff, and redesigning workflows to limit sleep interruptions at night. Hospital Consumer Assessment of Healthcare Providers and Systems Survey scores for quietness at night increased from 66% to 76%, with fewer reported cases of delirium postimplementation.
