Background: Traumatic brain injury (TBI) is a public health issue and the leading cause of mortality and coma status. Glasgow Coma Scale (GCS) and Full Outline of Un-Responsiveness (FOUR) score are reliable coma tools for assessing the level of consciousness (LOC) among critically ill patients in intensive care unit (ICU). An assessment of LOC and depth of coma is considered the primary action of critical care nurses (CCN). Therefore, conducting a training sessions will help to improve ICU nurses’ knowledge and perception of coma scales. Aim: This study aimed to assess the effectiveness of training sessions among Jordanian ICU nurses’ knowledge and perception toward GCS and FOUR score. Methods: A one-group pretest–posttest experimental design was utilized to assess the effectiveness of training sessions on ICU nurses’ knowledge and perception toward GCS and FOUR score. Total of 71 participants were recruited conveniently from five ICUs in five governmental hospitals. Data were collected by the researcher before the intervention, and immediately after the intervention was conducted using three tools to assess the socio-demographic characteristic, nurses’ knowledge regarding GCS and FOUR score, and nurses’ perception of GCS and FOUR score. Results: ICU nurses’ knowledge of GCS and FOUR score significantly improved (p<0.001) after the intervention. Regarding nurses’ perception, ICU nurses demonstrated a statistically significant improvement (p<0.001) in FOUR score. However, a significant (p=0.034) decrease in nurses’ perceptions of GCS appeared after the intervention. Conclusion: This study emphasize the importance of applying training sessions inside Jordanian ICUs settings to improve nurses’ knowledge and perception regarding GCS and FOUR score, as this helps improve critically ill patients’ outcomes and the quality of nursing care.
