Design outcomes

Primary

Measure	Time frame
Audio-visual reinforcement. Timepoint: From the second day after open heart surgery to the fourth day. Method of measurement: The demographic information checklist includes questions about the participants' personal characteristics such as age, gender, duration of surgery, underlying diseases, length of stay in the open heart intensive care unit, marital status, duration of surgery, and level of education, which will be obtained from the patient's and the patient's companion's hospitalization records. 2. Richmond Agitation and Drowsiness Scale: It is a complementary tool for recognizing and diagnosing delirium. This scale is used in addition to the Critical Care Unit Mental Distress Scale and has 10 levels, ranging from the unawakenable level, which has the lowest score (-5), to the severely agitated and aggressive level, which has the highest score (+4). If the patient receives a score higher than -2 on this scale, he should be evaluated on the Critical Care Unit Mental Distress Scale, but if the patient receives a score lower than -3, he should be re-checked on the Richmond at another time, and if these conditions prevail again, the presence of delirium is not considered. This scale has been used domestically and has acceptable coefficients, such that Cronbach's alpha coefficient is 0.7 and the agreement coefficient is 0.95, indicating acceptable agreement between raters.	—
