Background: Assessing the level of consciousness is a priority practice of health professionals, the Glasgow coma scale is a tool used to measure the level of consciousness of neurologically related patients. There has been limited evidence of easily of use and the more likely to misjudge, but Glasgow coma scale is still the leading tool widely used worldwide.
Objective: evaluate the related factors of Nurse' Knowledge in using Glasgow Coma Scale in Cho Ray Hospital.
Methods: A cross-sectional study design was conducted at a leading hospital in Vietnam using the Glasgow coma scale knowledge questionnaire. A total of 199 Nurses participated in this study, data collected from to be analyzed were analyzed using SPSS software.
Results: Education (Intermediate, colleges, university and master) affects the knowledge Glasgow coma scale of Nurses, Intermediate with the lowest level of knowledge, while knowledge in University and master groups is higher than with beta = 0.20, p = 0.017. Unit of work and time shift work position related to nursing knowledge when using Glasgow coma scale, working Nurses in Neurosurgery department with lows knowledge (32.6%), Neurosurgery Intensive care unit is (43.2%), Nurses at the department of Head Injury (55.6%), the highest is Neurology department (69%) with p = 0.008. Time shift work position from 1- 2 months has low knowledge, while the time shift work position from 3 -12 months has better knowledge than, beta = 0.33, p = 0.012.
Conclusion: This study proposes to develop a comprehensive and continuous education strategy for all Nurses and at the same time have a suitable time to change positions to improve knowledge when assessing the Glasgow coma scale.
