To assess the effect of preoperative theatre visit in reducing anxiety and its associated adverse outcomes, a single centre randomised controlled trial was conducted at the Professorial Gynaecology Unit, Colombo South Teaching Hospital, Sri Lanka. 64 patients were randomised. The intervention group had a pre-operative theatre visit with an informative session regarding the surgery. Patients’ anxiety before, at the time and after the surgery was assessed using APAIS score. Pre-induction parameters and pain score were also assessed. APAIS anxiety difference before the surgery and on the day of the surgery was −1.937 (±4.641) and −1.781 (±2.586) for the intervention and the control groups respectively (p = 0.643). There was no significant difference in pre-induction parameters between the groups. Pain score at 6 hours after surgery was 5.04 (±2.510) for the intervention group and 6.08 (±2.888) for the control (p = 0.189). Preoperative theatre visit prior to surgery made no significant difference in the patient’s anxiety, though a trend in reduction of anxiety and pain was noted. Impact statement What is already known on this subject? Patients experience significant anxiety before surgical procedures and high levels of anxiety can lead to adverse outcomes needing high induction doses of aneasthesia, delayed recovery and more postoperative pain. Different methods for preoperative anxiety reduction such as provision of systematic preoperative instructions, cognitive-behavioural interventions had been successful. What do the results of this study add? There are only a limited number of studies conducted assessing the methods of informational interventions to reduce anxiety. Preoperative theatre visit is a simple intervention that can be carried out without any additional preparation. What are the implications of these findings for clinical practice and/or further research? Our study could not show that preoperative theatre visit as an effective intervention in reducing anxiety in patients undergoing elective gynaecological surgery. However, there was a trend towards reduction in anxiety and postoperative pain with the intervention. Future research on providing additional information at the preoperative visit, timing of the visit and larger sample sizes may reveal better outcomes.
