Relevance to clinical practice
The findings of this study suggest that encouraging nurses to obtain knowledge about oral care from diverse educational sources and as an aspect of continuous lifetime learning will enhance their knowledge of oral care. Nursing administrators
at ICUs are also encouraged to establish policies and procedures for oral care for intubated patients in accordance with the type of patients they care for, in addition to holding in-service training in their ICUs, with a view to enhancing the quality of oral care for critically ill patients.
