Effect of Educational Intervention on Nurses’ Knowledge and Practices Regarding Endotracheal Tube Suctioning

Abstract

Background: Endotracheal tube suctioning (ETS) is a critical procedure in intensive care, but gaps persist in nurses’ knowledge and practice despite its established importance. Addressing these gaps through education may reduce complications and standardize care. Objective: To evaluate the effect of a structured educational intervention on the knowledge and practical adherence of critical care nurses and doctors to evidence-based ETS protocols. Methods: This quasi-experimental pre-post study enrolled 100 healthcare professionals at a university-affiliated hospital. Knowledge and practice regarding ETS were assessed using validated questionnaires and observational checklists before and after a multi-modal educational program. Statistical comparisons were performed using paired t-tests, Wilcoxon signed-rank tests, and chi-square tests. Results: Mean knowledge scores improved from 3.6 (SD 0.51) to 3.8 (SD 0.36) post-intervention (p < 0.001). Adherence to core ETS practices increased from 93% to 97% (p < 0.001), with the largest gains observed for previously underemphasized items. No significant differences were detected by gender, age, or professional role. Conclusion: Structured education significantly enhances both knowledge and adherence to best-practice ETS protocols, supporting the need for continuous, standardized training to optimize patient outcomes in critical care.
