Anxiety, Physiological Parameters, Patient Satisfaction and VR in Gynecological Oncology Surgery

Official title

The Effect of Virtual Reality Intervention on Preoperative Anxiety, Physiological Parameters and Patient Satisfaction in Women Scheduled for Gynecological Oncology Surgery: A Randomised Controlled Trial

Overview

Surgical procedures often cause significant anxiety in patients, particularly among women undergoing gynecological oncology surgeries. Preoperative anxiety is a common and preventable condition that can negatively affect both physiological parameters and the overall surgical experience. It may lead to increased heart rate, elevated blood pressure, respiratory distress, and psychological discomfort, increasing the risk of complications during and after surgery. Women facing gynecological cancer surgery often experience heightened anxiety due to concerns about survival, loss of reproductive organs, body image changes, and sexual health. Virtual reality (VR) has emerged as a promising non-pharmacological approach for reducing preoperative anxiety. By immersing patients in a calming virtual environment that engages visual and auditory senses, VR helps promote relaxation, reduce stress, and enhance the patient's sense of control before surgery. It is safe, easy to implement, cost-effective, and does not have the side effects associated with medications. Although VR has demonstrated effectiveness in reducing anxiety in various surgical contexts-including orthopedic, colorectal, and minor gynecological procedures-its impact in gynecologic oncology surgery remains underexplored. This randomized controlled trial aims to evaluate the effect of a VR intervention on preoperative anxiety, physiological parameters (blood pressure, heart rate, respiratory rate, oxygen saturation), and patient satisfaction in women scheduled for gynecologic oncology surgery. Participants will be randomly assigned to either the intervention group (receiving VR) or the control group (receiving standard care). Anxiety and physiological measures will be evaluated before and after the respective intervention in both groups. Patient satisfaction will be assessed once, immediately after the intervention and before surgery. The primary objective is to assess whether VR effectively reduces preoperative anxiety and stabilizes physiological indicators. The secondary objective is to evaluate patient satisfaction with the preoperative experience. This study will contribute to the evidence base for using VR as a nursing-led, non-invasive strategy to enhance surgical care in gynecologic oncology.

Detailed description

Preoperative anxiety is a common and preventable psychological condition that significantly affects surgical outcomes and patient well-being. Women undergoing gynecologic oncology surgery often face elevated levels of anxiety due to the severity of their diagnosis, potential loss of reproductive organs, and concerns related to survival, body image, and sexuality. These psychological stressors can lead to physiological changes such as increased blood pressure, heart rate, and respiratory distress, which in turn may complicate surgical procedures and recovery. Managing preoperative anxiety effectively is essential not only to minimize surgical risk but also to improve patient satisfaction and postoperative adaptation.

Pharmacological methods used to manage preoperative anxiety can carry risks such as side effects, drug interactions, and delayed postoperative recovery. For this reason, non-pharmacological interventions such as virtual reality (VR) have gained popularity in recent years. VR allows patients to be immersed in a multisensory virtual environment that helps distract their attention away from surgery-related fears and fosters relaxation. Studies in orthopedic, colorectal, and minor gynecologic procedures have shown that VR can reduce anxiety and improve physiological responses before surgery. However, limited evidence exists regarding its use in women undergoing gynecologic oncology surgery-a population that faces unique psychological and physical challenges.

This study is a two-arm randomized controlled trial designed to evaluate the effectiveness of a virtual reality (VR) intervention in reducing preoperative anxiety and stabilizing physiological parameters in women scheduled for gynecologic oncology surgery via laparotomy. A total of 66 participants will be randomly assigned to either the intervention group (VR session) or the control group (standard care). In both groups, anxiety levels and physiological parameters (blood pressure, heart rate, respiratory rate, and oxygen saturation) will be assessed before and after the intervention. Patient satisfaction with preoperative care will be assessed only once, following the intervention or standard care session, immediately before surgery.

Eligibility criteria include adult women (≥18 years) with a confirmed diagnosis of gynecologic cancer who are aware of their diagnosis and scheduled for their first surgical intervention via laparotomy. Participants must have an ECOG Performance Status ≤2 and must not have any cognitive, visual, auditory, or psychiatric impairments that could interfere with communication or VR use. Exclusion criteria include recurrent cancer, motion sensitivity (e.g., vertigo or migraines), or any condition preventing the use of VR headsets.

The study aims to contribute new evidence supporting the use of VR as a nurse-led, low-risk, and effective non-pharmacological approach to improve preoperative experiences and perioperative outcomes in women facing gynecologic oncology surgery.

Interventions

• Behavioral Virtual Reality Relaxation Session
  A 20 minute virtual reality session using visual and auditory stimuli for relaxation before surgery. Delivered via VR headset.

Primary outcome measures

• Preoperative Anxiety Score [Time frame: Immediately before and immediately after the intervention, on the day of surgery]
• Change in Systolic and Diastolic Blood Pressure [Time frame: Immediately before and immediately after the intervention, on the day of surgery]
• Change in Heart Rate [Time frame: Immediately before and immediately after the intervention, on the day of surgery]
• Change in Respiratory Rate [Time frame: Immediately before and immediately after the intervention, on the day of surgery]
• Change in Peripheral Oxygen Saturation [Time frame: Immediately before and immediately after the intervention, on the day of surgery]

Secondary outcome measures (1)

• Preoperative Patient Satisfaction Score [Time frame: Immediately after the intervention (same day, pre-surgery)]
