摘要:INTRODUCTION: Majority of critical care nurses do not have desirable skills in performing endotracheal tube suctioning (ETS) despite related training taught in the curricula. This study aimed to investigate and compare the effect of education through video and performance feedback (PF) on nurses' skills in performing ETS. METHODS: This was a quasi-experimental study. The sample size comprised of all nurses ( n = 49) working in the intensive care unit of one of the educational hospital located in one of the western cities of Iran. Nurses were assigned to either one of educational video (EV) and PF groups. Data were collected using a 25-item structured best practices information sheet. Data were analyzed using SPSS software version 20 (SPSS Inc., Chicago, IL, USA). RESULTS: After the interventions, no significant difference was found in the total mean score of nurses' practice in ETS between those who received education through EV and those who received through PF (16.3 vs. 15.1) ( P > 0.05). Before and after the intervention, a significant improvement was observed in the total mean score and other dimensions of nurses' practice in endotracheal suctioning ( P < 0.0001). CONCLUSIONS: The results showed that both of methods through feedback and EV are useful in improving nurses' ETS practice. However, further studies are required to examine the effects of such interventions in the long term.
