Background: Electrolyte imbalance, fear of death and illness, and homesickness are among the factors that may susceptible the patients hospitalized at Coronary Care Units (CCUs) to delirium. This study aimed to investigate the effect of modification of sensory stimulations on the reduction of delirium occurrence rate in patients admitted to CCU.
Methods: The present clinical trial was performed on 80 patients hospitalized at the CCU of Vasei Hospital affiliated to Sabzevar Medical University, Iran. The subjects were randomly assigned to the control and experimental groups (40 subjects in each). The control group received no intervention, while some environmental modifications like putting a clock and a calendar at the patient’s bedside were provided for the patients in the experimental group. Neecham Confusion Scale was used to collect the necessary data concerning the occurrence of delirium in both groups, twice a day (morning and afternoon) for 3 consecutive days. The obtained data were analyzed by Independent t-test, Mann Whitney U Test, and logarithmic link for the model fit using SAS. 
Results: The results showed 14 (35%) cases of delirium in the control group, and 3 (7.5%) cases in the experimental group. Moreover, the results of the analyses indicated no statistically significant difference between the 2 groups, on the first day (P=0.74). However, the 2 groups were significantly different in terms of delirium occurrence, on the second (P=0.03) and the third (P=0.003) days. 
Conclusion: The results confirmed that modification of the sensory stimulations can lead to a significant reduction of the delirium rate among the patients hospitalized at CCUs.

● Delirium in patients hospitalized in coronary care units are common.
● Delirium can be decreased in these patients by providing suitable environmental modifications.
● These modification include more cooperation of the medical staff, describing the environmental conditions, and allowing relatives to see the patient.
Plain Language Summary
Delirium is one of the oldest known medical disorders, characterized by acute and swirling start (several hours to several days) disturbances in consciousness, orientation, memory, thinking, perception, and behavior. The patients hospitalized at coronary care units are susceptible to delirium which is responsible for an increased death rate among these patients. The results obtained in the present study confirmed that the modification of the sensory stimulations can significantly reduce the delirium rate among the patients hospitalized at coronary care units.
