In the intervention group, the voice of Quran plays twice daily for 10 minutes each time. Patients are evaluated twice daily for Delirium. In the control group, routine care will be performed.

Delirium

In this study, patients will be randomly assigned to the study. By assigning the letter A to the intervention group and the letter B to the control group, the ABBA ،BABA ،ABAB ،BBAA ،AABB ،BAAB are written in separate sheets and inserted into the container. Then, we randomly take one of these sheets out of the container and write the written compound on it and replace that sheet inside the container. Since the sample size in this study is 108 patients, this procedure is repeated twenty-seven times, and each time the composition is written on each sheet in the sequence of the compound written in the previous sheet is noted. Then each of the letters of a number from one to 108 is assigned sequences written in sequence, and each of the letters is placed inside a packet and written on the envelope of that letter. Each time the patient is selected, one of these packets is opened in the order of the number written on the envelope, and it is determined that the patient should be placed in the intervention or control group.

The colleague of the researcher will be responsible for assigning patients to the control and intervention groups, and the researcher who has the task of evaluating the outcome will not know how to allocate patients.
