Background: Intensive care unit (ICU) nurses play a key role in preventive care. Their knowledge, attitudes, and performance in endotracheal suctioning and oral care are essential to prevent respiratory complications in intubated patients.
Objective: This study aimed to assess ICU nurses’ knowledge, attitudes, and performance regarding endotracheal suctioning and oral care in intubated patients, and to identify factors associated with thesedomains.
Methods: This cross-sectional study was conducted between May and November 2023 using a census of all 200 ICU nurses working in hospitals affiliated with Ardabil University of Medical Sciences. Data were collected using demographic form and a questionnaire on nurses’ knowledge and performance in endotracheal suctioning, and knowledge, attitudes, and performance in oral care. Knowledge and attitudes were self-reported, while performance was observed using a checklist over two sessions. Data were analysed in SPSS v.23 using Pearson correlation, independent t-test, and ANOVA.
Results: Nurses’ mean (SD) knowledge, attitudes, and performance were 65.2 (15.5), 39.2 (3.5), and 54.6 (26.5) for oral care, and 33.4 (10.9) and 70.9 (15.0) for endotracheal suctioning knowledge and performance. Significant differences were observed in oral care performance by gender (p= 0.004), marital status (attitude: p= 0.024; performance: p= 0.002), and education (p< 0.001), and in suctioning knowledge (p= 0.010) and performance (gender: p= 0.011; workshop: p< 0.01).
Conclusion: gap was observed between nurses’ knowledge and performance, especially in oral care, highlighting that improving clinical performance requires more than knowledge alone and may be influenced by factors such as gender, marital status, education, and training experience.
