Intensive and critical care nurses patient safety, care quality, professional self-efficacy, and missed nursing care: Structural equation model analysis.

ICCU nurses' care quality and professional self-efficacy are essential mediating factors that can bolster patient safety practices, hence reducing missed nursing care. Therefore, healthcare organizations, nurse managers, and policymakers should cultivate care quality and self-efficacy by creating support programs and providing a positive practice environment. Nurses and nurse supervisors could directly observe missed nursing care in the ICCU to understand its underreported causes.
