This study was conducted to assess the effect of multi-component intervention to prevent post operative delirium I patients who underwent open–heart surgery. In this clinical intervention study 32 patients (45 to 70 years of age) who underwent open–heart surgery were divided into two groups of 16 patients (case and control). Six risk factors included: cognitive, visual and auditory impairment¸ immobility, dehydration and sleep deprivation were assessed in both groups for three consecutive days starting from the second after operation. A standard protocol was used for case group. Incidence of delirium was determined by clinical interview; based on DSM-IV-TR; twice a day (morning and evening). The collected data were analyzed by t-test and S- plus statistical methods. The median of total number of risk factors and immobility in case group were significantly reduced in comparison to control group0 There was reduction in the trends related to other risk factors and incidence of delirium in the case group. The finding of this study demonstrates that primary prevention of delirium is an effective treatment strategy among post-open-heart surgery0
