Participants are randomly assigned to either the intervention group (mobile-based mindfulness intervention + usual care) or control group (usual care only).\n\nThe intervention uses a free and anonymous mindfulness mobile app developed by The University of Hong Kong.\n\nPrimary Outcome:\n\nPreoperative anxiety level on the day of surgery, will be assessed using the STAI-S questionnaire.\n\nSecondary Outcomes:\n\nPostoperative pain levels, use of analgesics, emergency department revisit rate, and user satisfaction with the app.\n\nData Collection:\n\nAnxiety levels are measured at baseline and before surgery. Pain levels and analgesic use are recorded postoperatively. Emergency visits and usability feedback are collected post-discharge.\n\nSignificance:\n\nThe study addresses a gap in evidence for mobile mindfulness interventions in Chinese surgical patients.\n\nFindings may support the integration of low-cost, app-based mindfulness into preoperative care.",[27,28,29,30],"Mobile-based Mindfulness Intervention to Reduce Preoperative Anxiety","Pre-operative Anxiety","Postoperative Pain","Postoperative Use of Analgesics",[32,33,34,35],"Mobile-based mindfulness","pre-operative anxiety","post-operative pain","postoperative use of analgesics","RECRUITING","2025-09-09",{"date":39,"type":40},"2025-09-11","ACTUAL",{"date":42,"type":40},"2025-06-13",{"date":44,"type":21},"2026-12-31",{"name":46,"class":47},"Hospital Authority, Hong Kong","OTHER_GOV"]
