Effects of Mobile-based Mindfulness Intervention to Reduce Preoperative Anxiety for Patients Undergoing Elective Surgery

This study is a pilot randomized controlled trial (RCT) conducted at Tin Shui Wai Hospital to evaluate the effectiveness of a mobile-based mindfulness intervention in reducing preoperative anxiety among patients scheduled for elective surgery. Aim: To determine if a 4-week mindfulness program delivered via a mobile app can reduce preoperative anxiety, compared to standard care. Design: Parallel-arm RCT with 40 participants (20 in each group). Participants are randomly assigned to either the intervention group (mobile-based mindfulness intervention + usual care) or control group (usual care only). The intervention uses a free and anonymous mindfulness mobile app developed by The University of Hong Kong. Primary Outcome: Preoperative anxiety level on the day of surgery, will be assessed using the STAI-S questionnaire. Secondary Outcomes: Postoperative pain levels, use of analgesics, emergency department revisit rate, and user satisfaction with the app. Data Collection: Anxiety 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. Significance: The study addresses a gap in evidence for mobile mindfulness interventions in Chinese surgical patients. Findings may support the integration of low-cost, app-based mindfulness into preoperative care.

Informative Video to Alleviate Anxiety and Improve Satisfaction in Elective Caesarean Section

Title: "Study of Informative Video on Alleviating Perioperative Anxiety and Improving Satisfaction Score in Obstetric Patients Undergoing Elective Lower Segment Caesarean Section Under Spinal Anaesthesia" Objective: This study aims to evaluate the effectiveness of an informative video in reducing perioperative anxiety and enhancing satisfaction in obstetric patients undergoing elective Caesarean sections under spinal anaesthesia. The hypothesis is that patients who view the video will experience lower anxiety and higher satisfaction compared to those who receive standard pre-anaesthetic counselling alone. Background: Spinal anaesthesia, commonly used for Caesarean sections, offers rapid, predictable pain relief but can cause discomfort due to factors such as visceral pain and fundal pressure, leading to perioperative anxiety. Anxiety can negatively impact maternal satisfaction and increase the risk of postpartum complications. Previous studies have shown mixed results regarding the efficacy of educational videos in alleviating this anxiety. Methods: The study is a prospective, randomized controlled trial conducted at Universiti Malaya Medical Centre. Eligible participants are obstetric patients (ASA II-III) undergoing elective Caesarean sections. Participants are randomly assigned to either an intervention group, which receives a supplemental informative video, or a control group receiving standard care. Anxiety and satisfaction levels are assessed using validated questionnaires pre- and post-surgery. Anticipated Outcomes: The study hypothesizes that the informative video will significantly reduce perioperative anxiety and improve maternal satisfaction, thereby demonstrating the superiority of this intervention over standard pre-anaesthetic counselling.
