Effects of Virtual Reality-Based Education on Pre-treatment Anxiety, Post-treatment Experience, and Satisfaction Among Adult Patients Diagnosed With Cancer Receiving External Beam Radiotherapy in Oman

Introduction Cancer and its treatments often inflict considerable physical and psychological distress on patients, despite advancements in treatment modalities, including surgery, chemotherapy, and radiation therapy. Among these treatments, external beam radiotherapy (EBRT) is a common method that utilizes ionizing radiation to target and eradicate malignant cells. However, the experience can be daunting for patients, often leading to anxiety. To mitigate these adverse psychological effects, patient education has emerged as a crucial component of cancer care by providing patients with comprehensive information about their condition, the necessity for radiotherapy, and the technology involved, healthcare professionals can alleviate concerns and improve understanding. The abstract nature of radiation and its potential side effects can be difficult to visualize, leading to heightened anxiety and misperceptions. In recent years, virtual reality (VR) has emerged as a promising tool for enhancing patient education and support in various healthcare settings. VR offers an immersive, computer-generated simulation of real or imagined environments, providing users with a sense of presence and interaction. In the context of cancer care, VR can illustrate the objectives and processes of radiotherapy in a visually compelling manner, which is difficult to achieve with traditional methods, by allowing patients to virtually experience the radiotherapy process. VR interventions have been associated with significant reductions in anxiety.

Cancer Care in Oman:

Cancer is a significant health concern in Oman and is the leading cause of death, accounting for 6% of all disease-related mortality. The Oman National Cancer Registry, established in 1985, plays a crucial role in monitoring cancer incidence and trends; as a result, cancer diagnosis notification has been mandatory since 2001, ensuring comprehensive data collection. Radiation therapy was not available in Oman; the government sponsored approximately 250 patients annually to receive radiation treatment abroad before 2004. The National Oncology Center (NOC) at the Royal Hospital in Muscat, launched in 2004, is the oldest center and treats around 70% of all cancer cases in Oman.

External Beam Radiotherapy External Beam Radiation Therapy (EBRT) is an external irradiation source, usually a linear generator, that is used in this procedure to precisely administer high levels of radiation to cancer regions while lowering the dosage to nearby healthy tissues. To meet patients' psychological and physical requirements as they progress throughout the complicated radiation treatment (RT) process, patient education is crucial. Patients may experience physical and psychological impacts from RT and cancer treatment. Many patients experience anxiety, particularly at the commencement of treatment. Traditional methods include slides, printed materials, and in-person interactions, as well as video materials that have improved patient satisfaction and decreased anxiety. Virtual Reality (VR) is a powerful tool for patient education, as immersive virtual experiences can decrease anxiety. Virtual integration of patient education in radiotherapy (VIPER), using videoconferencing, is a feasible and acceptable method for patient education. Although the combined client-provider decision-making guidelines allow the multidisciplinary healthcare team to repeat and strengthen training and give patients several chances to raise concerns, it can also result in unequal education, misunderstandings, and false presumptions. One typical emotional reaction to malignancy is anxiety while preparing for radiotherapy. Long before the initial consultation, patients want to know about the radiation process. A patient's request for details is influenced by several aspects, such as who they are interested in receiving it from, at what time they want it, and in what style. The Radiotherapy Experience Questionnaire (RTEQ) can measure how patients experience the external RT session process and the environment in the treatment room.

Virtual Reality in Healthcare:

Over the past two decades, VR has found various applications in healthcare, offering immersive and non-immersive experiences. VR has evolved through two generations of technology: First-generation SLEs used machines to replicate real-life experiences, while more recent advancements include sophisticated software and hardware. VR enhances patient understanding of medical treatments like radiation therapy. For instance, VR can be used to educate patients about the radiotherapy process, reducing anxiety. VR serves as a distraction intervention to relieve symptoms such as anxiety. It is used during medical procedures to reduce anxiety. Studies have shown VR's effectiveness in reducing anxiety, particularly in patients undergoing medical interventions and cancer treatment. VR offers oncology sufferers emotional, physical, and emotional assistance.

Virtual Reality and Patient Education:

Virtual Reality (VR) can be enjoyable, which is important for learning, as a pleasant experience means higher engagement and understanding. VR educational sessions reduce their anxiety levels and allow patients to utilize audio and geographical aspects during radiation treatments to have an actual treatment experience. Personalized VR experiences can give patients a better understanding of how radiotherapy will be used to treat their cancer and can decrease anxiety. VR-based education is feasible and acceptable about their illness and satisfaction with treatment. VR experience should be guided by a healthcare professional considering the timing of the experience and its incorporation into an education session. Studies show that VR educational sessions can enhance cancer patients' preparation for radiation therapy by increasing their understanding of treatment and reducing anxiety. Patients with poor health literacy abilities may benefit most from media in the form of video tutorials. VRRT provides RT clients with a novel educational experience, particularly in allowing them to see how to treat and the significance of their position during treatment and the physical location within the human body. Patients are highly satisfied and experience enhanced understanding with VR education tools. Patients appreciate the 3D vision display provided by VR, which effectively improves RT understanding. Patients' knowledge requirements on the RT procedure can be met using virtual reality (VR), which enables them to communicate within the environment, familiarize themselves with the RT tools, and see what will occur throughout the course of treatment. Many patients request additional details that they are not provided. VR provides additional information that traditional teaching sessions cannot provide, with patients referring to VR video's capacity to improve comprehension of the treatment's visual and auditory features. Healthcare providers also report a significant amount of satisfaction using VR, recognizing its benefits for treatment and simplicity of application. RT units may benefit from including a virtual reality teaching setting as an additional patient education resource. VR offers an exceptional educational experience with minimal intervention from clinical staff. VR could minimize the need for one-on-one consultations, which could decrease the burden on employees. VR education should be individualized to meet the needs of each patient.

Anxiety in Cancer Patients:

Anxiety is a natural emotional reaction to receiving a cancer prognosis and receiving therapy. Cancer-related anxiety can lead to impaired social functioning and fatigue. Anxiety may arise from various reasons, including reaction to the cancer diagnosis, severe pain, long-term treatments, treatment side effects, and feeling of burden or dependence on others. Procedural anxiety can occur during or in anticipation of the procedure and may lead to behavioral disruptions, such as avoiding or terminating medical procedures. High levels of anxiety can negatively impact health, increasing treatment nonadherence, promoting unhealthy lifestyle factors, and chronically activating stress hormones. Anxiety can affect patients' learning capacity. Anxiety levels decrease once RT starts, falling from 29.9% to 17.4%. The State Anxiety Inventory (SAI) is commonly used to measure procedural anxiety. To minimize anxiety, successful instruction needs to tackle patient issues, give sufficient details for consent to be informed, and get patients ready for the RT procedure, addressing potential adverse outcomes. Non-pharmacological interventions such as virtual reality (VR) have shown promise in reducing anxiety. Relaxation techniques and counseling are also recommended. Virtual reality (VR) is utilized to reduce anxiety and distress in cancer patients, offering relaxation through immersive experiences. Patients with cancer have different information requirements depending on the patient's age, gender, socioeconomic status, and level of education, as well as cultural differences that can affect how patients express and cope with anxiety. Patient education is a cornerstone of cancer treatment preparation. Providing information before, during, and after RT helps gain patient trust and ensures they feel valued. Education can alleviate concerns by informing patients about their ailment, the need for RT, and the technology used. Patients with inadequate health literacy could benefit most from interactive instructional videos. VR educational sessions can enhance cancer patients' preparation for radiation therapy by increasing their understanding of treatment and reducing anxiety. Pretreatment education through written materials and multimedia can reduce anxiety in patients undergoing radiotherapy. A radiotherapy therapist's declaration of a particular individual technique can lead to patients feeling more informed and greater satisfaction, although it may not always decrease anxiety.

Patient Experience:

The technical settings and instruments have a significant impact on the patient's treatment experience in the external radiotherapy (RT) context, as this is because the patient's view of RT processes and instruments is crucial to assess as a supplement to devices like treatment results and consistency. Patients and their caregivers may experience both the emotional and physical effects of radiation therapy. Mask-related anxiety can significantly affect the experience of patients undergoing radiotherapy for head and neck cancer. Important roles are also played by data obstacles, health care professional (HCP) engagement, and incentives for improved information dissemination. The Radiotherapy Experience Questionnaire (RTEQ) evaluates the patient's experiences of the external RT method, including anxiety and adapting throughout the external radiation therapy technique, as well as aims to evaluate the patient's impressions of the RT procedure and the therapeutic area setting. Information should be tailored based on patient characteristics, as certain clients would rather have fewer details or engage their relatives in their care to reduce their anxiety. Cultural factors can affect how patients express and cope with anxiety, and physicians may avoid informing patients of their diagnosis, with families disagreeing with disclosure. Patient experience significantly affects treatment adherence and outcomes. Patients who are unprepared, lack engagement, are unwilling to follow evidence-based radiation regimens that enhance clinical results, and have a diminished capacity for self-management of care. Disruption of treatment due to anxiety may have negative consequences for the outcome. Several strategies can enhance the patient's experience in radiotherapy, like providing patient-specific information and support by utilizing multiple teaching strategies available to them. Employing Patient and Public Involvement (PPI) and patient advocacy to inform future studies. Using virtual reality (VR) to educate and prepare patients for radiotherapy. VR can reduce anxiety and enhance satisfaction. Offering calming video content during treatment. Creating a mindfulness-promoting environment with VR. Radiotherapy Therapists (RTTs) can provide pre-radiation treatment patient instructions to improve patients' anxiety and overall experiences. Making sure clients receive on-time and adequate instruction could help them feel less anxious before receiving radiation therapy and could also help address the related effects on patients and healthcare facilities. The use of interventions applicable to radiotherapy that are administered to improve patient comfort, increase patient compliance, and reduce patient anxiety.

Patient Satisfaction:

Patient satisfaction is influenced by a multitude of factors, reflecting the complex nature of healthcare delivery. Accessibility to healthcare services, including ease of access, convenience, and availability of care, significantly impacts patient satisfaction. Information provision plays a crucial role, as patients value being well-informed about their condition, treatment options, and potential side effects. Patient expectations are a critical determinant, with satisfaction resulting from a comparison of perceived performance or outcome in relation to these expectations. A positive patient experience can enhance confidence in the health system and help patients cope with the disease. Patient-centered care models that prioritize patient needs and preferences are essential. Providing comprehensive and accessible information about cancer, treatment options, and potential side effects empowers patients and enhances satisfaction. Enhancing the physical environment of healthcare facilities can create a more comfortable and welcoming experience for patients. Offering support services such as counseling, support groups, and palliative care can address the behavioral and emotional requirements of clients and their relatives. Utilizing virtual reality (VR) and other innovative technologies can improve patient education, reduce anxiety, and enhance the overall treatment experience. Continuous quality improvement initiatives that incorporate patient feedback can help identify areas for improvement and ensure that services meet patient expectations.
