It causes several complication,bad prognosis and even mortality. Due to several side effects of drugs, music can be a nonpharmacological unrisk method for prevention of delirium. The purpose of the present study was to determin the effect of music on post operative delirium in elder women who underwent hip surgery hospitalized in orthopaedic ward. Materials and methods: The present study is a semi experimental research. The samples were including 100 old women over 65 years of age with hip fracture in khorramabad Shohada hospital during 4 month. They were allocated according to inclusion criteria and sampling method to 2 equal groups of intervention and control, each with 50 persons. The tools of gathering data were demographic questionnaire, screening questionnaire and mini-mental state examination(MMSE). First, patient`s cognitive state were assessed by MMSE. Music was played for persons in intervention group for 20 minute, three times daily from 1 day before surgery until 4 days after surgery,while participants in the control group received standard care. During the intervention ,patient`s cognitive state was assessed by MMSE two times daily. Then patient`s were divided in 2 groups before and after scores in intervention group were compared. Results: Findings showed that there is significant difference between before and after scores in intervention group(p=0/018). This difference even was significant with modification of before cognitive scores (p<0.001) and age (p<0.001)of intervention group. Conclusion: This study provides evidence that music listening is an effective and unrisk tool for prevention of post hip surgical delirium in elders.
