Abstract
PURPOSE: Surgery is the primary curative treatment for colorectal cancer; however, it remains a frightening procedure that can cause stress and pain in affected patients. Therefore, patients typically experience significant anxiety during the preoperative period, which has been associated with poorer outcome after surgery. This study aimed to evaluate the effect of an Internet-based informational video on preoperative anxiety level in patients with colorectal cancer. METHODS: This prospective, single-arm, observational study included patients scheduled to undergo elective colorectal cancer surgery, who did not have a history of previous surgery or major cognitive impairment. The primary outcome measure was the change in Amsterdam Preoperative Anxiety and Information Scale - Anxiety (APAIS-A) before and after watching a 5-min informational video (https://youtu.be/VzhtOMPUe4Q) during the preoperative period. Secondary outcome measures were the change in Hospital Anxiety and Depression Scale (HADS), length of postoperative hospital day, and postoperative morbidity. RESULTS: Thirty-two patients were enrolled. Anxiety was significantly decreased after watching the video (APAIS-A score: from 10.8 ± 3.7 to 8.2 ± 3.2, P < 0.001, mean reduction: 22.2%). HADS score was also significantly decreased (from 5.8 ± 4.4 to 4.0 ± 3.3, P = 0.001, mean reduction: 26.5%). All preoperative anxiety level did not significantly differ between patients who developed postoperative complication and those who did not. CONCLUSION: The informational video was an effective tool to reduce preoperative anxiety. Viewing this video may confer a higher level of confidence and realistic expectations, as well as reducing patients' preoperative anxiety.
