Introduction: Due to the complexity of the situation and rapid changes in patients' clinical status in intensive care units, it is necessary to teach decision-making skills to nurses, alongside critical thinking. The aim of this study was to evaluate critical thinking training by using critical thinking cards on clinical decision-making of nurses in cardiac care units (CCU).
Methods: In this quasi-experimental study, 74 CCU nurses from the selected hospitals affiliated to Ahvaz and Dezful Universities of Medical Sciences were selected based on the inclusion criteria and were assigned to either the intervention or the control group by using permuted block randomization.
