What this trial studies

This is a pilot parallel-arm randomized controlled trial at Tin Shui Wai Hospital enrolling 40 adults scheduled for non-emergency surgery under general anesthesia. Participants are randomized 1:1 to receive a four-week mobile-based mindfulness program plus usual care or to receive usual care alone. The primary outcome is preoperative anxiety measured with the STAI-S on the day of surgery; secondary outcomes include postoperative pain, analgesic use, emergency department revisits, and user satisfaction with the app. The intervention uses a free, anonymous mindfulness app developed by The University of Hong Kong and targets patients with baseline trait anxiety (STAI-T ≥ 40).

Who should consider this trial

Good fit: Ideal candidates are adults (≥18 years) who speak Chinese, own a smartphone, are scheduled for non-emergency surgery under general anesthesia, and have an STAI-T score of at least 40.

Not a fit: Patients currently being treated for psychiatric conditions, with serious comorbidities, sensory impairments, emergency surgeries, or those without smartphone access are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, this low-cost, easy-to-deliver app could reduce anxiety before surgery and possibly improve postoperative pain control and reduce analgesic use.

How similar studies have performed: Mindfulness-based interventions have shown benefit for reducing stress and anxiety in prior studies, and mobile-delivered mindfulness is a growing but less extensively tested approach.
