Background and Objective: The present study assessed the effects of multi-component intervention on preventing delirium after open heart surgery.

Material and Methods: This clinical intervention study was conducted on 32 patients (aging 45-70 years) after open heart surgery, in two matched groups of 16 subjects. From the second day after surgery to three days later, six risk factors including cognitive, visual and hearing disorders, dehydration, immobility and sleep deprivation were evaluated and intervention was performed on the case group using standard protocol. The incidence of delirium was determined by clinical interview based on DSM-IV-TR, twice a day (morning and evening). Data were analyzed using t test and comparison of proportions (S-Plus).

Results: The median of the total number of risk factors and immobility were significantly reduced in the case group compared to the control group. Other risk factors and incidence of delirium showed a tendency to decrease.

Conclusion: Primary prevention of delirium is probably the most effective treatment.
