Methods: A descriptive correlational study was conducted with 120 patients who met the inclusion criteria and were selected through purposive sampling. Data were collected using a baseline demographic proforma, a preoperative anxiety scale, and a preoperative sleep quality scale to assess the relationship between anxiety levels and sleep quality prior to surgery.

Results: Findings indicated that 54.2% of patients reported moderate anxiety, with a mean preoperative anxiety score of 25.11±6.32, representing 52.31% of the possible score. In terms of sleep quality, 66.7% of patients experienced mild sleep disturbances, with a mean sleep quality score of 19.36±6.41, representing 40.33% of the possible score. A weak positive correlation between preoperative anxiety and sleep quality was found (r=0.244, p=0.007), suggesting that increased anxiety is associated with poorer sleep quality.

Conclusion: Healthcare professionals play a critical role in managing preoperative anxiety and improving sleep quality. Educating and training nurses on strategies to reduce patient anxiety and enhance sleep quality may improve patient outcomes. These findings highlight the need for targeted interventions to support preoperative patients in managing anxiety and optimizing recovery.
