Aim of the study: This study aimed to evaluate the effect of the educational program on nurses' performance regarding subglottic suction and patients outcomes. Setting of the study was applied in general (ICU) at Beni–Suef University hospital. The study sample consisted of two subjects (patient and nurse). A convenient sample of 35 nurses and her 80 ventilator patients who met inclusion and exclusion criteria. Tools for Data collection. Tool (I) Nurses’ self-administered questionnaire: Tool (II) Subglottic suction observational checklists. Tool (III): Nurses' attitudes scale. Tool (IV) Patients' interview questionnaire. Tool (V) Modified clinical pulmonary infection score (MCPIS).

Results: The main results were a mean ± SD for age of 25.14 ± 3.28, a significant difference in nurses' knowledge among the three phases of the study (0.000**) (0, 42.9, 34.3), and nurses' It showed that there was an improvement in knowledge. Overall level of knowledge and practice in immediate post-program follow-up and post-program implementation compared to pre-program. On the other hand, we found that her 98.8% of patients were not diagnosed with ventilator-associated pneumonia (VAP) after 48-96 hours of intubation.

Conclusion: Improvements in student-nurse performance on subglottic suction are statistically different across the three study phases. The results also showed no significant difference in terms of VAP scores, indicating a small number of cases with VAP. Finally, application of educational programs had a positive effect on trained nurses' performance and patient outcomes, supporting our research hypothesis.
