The Effect of Eye Mask and Earplugs on Sleep Quality and Delirium in Coronary Artery Bypass Graft Patients: A Randomized Controlled Study

Primary outcomes

1. Richards-Campbell Sleep Scale

   Time frame: Repeated monitoring will be performed using RCUÖ and Nu-DESC on the 2nd, 3rd and 4th days after surgery.

   The RCUS was developed by Richards and colleagues (1987) to assess sleep. The RCUS includes six items (sleep depth, time to fall asleep, frequency of awakenings, time to remain awake when awakened, quality of sleep, and ambient noise level). Each item is rated using a 0-100 visual analog scale. The total score is obtained by dividing the individual items by their numbers: 0 represents the worst sleep, 100 the best sleep. As the score obtained from the scale increases, the sleep quality of the patients also increases. The RCUS provides a short, applicable, comprehensive, and simple tool for assessing sleep quality in the intensive care unit and is the most common. The Cronbach α value of the scale was found to be 0.82. The validity and reliability study of the scale in our country was conducted by Karaman Özlü and Özer (2015). The Cronbach Alpha internal consistency coefficient of the scale was found to be 0.91.

2. Nursing Delirium Screening Scale- Nu-DESC

   Time frame: Repeated monitoring will be performed using RCUÖ and Nu-DESC on the 2nd, 3rd and 4th days after surgery.

   The scale consists of five items. These are; disorientation, inappropriate behavior, inappropriate communication, illusion-hallucination and slowness in psychomotor behavior. It is critical that all subtypes can be detected in an effective delirium diagnosis. Among the items in Nu-DESC, it is thought that hypoactive delirium is detected more successfully with the item that evaluates psychomotor slowness. Each item in the scale takes a value between 0 and 2 points and the total score varies between 0 and 10. Two points and above indicate delirium. The evaluation time is approximately one minute.
