e-Natureza Blue Care: Nature-based Virtual Reality and Pain Perception

Condition(s) studied

Investigational drug(s) / intervention(s)

Nature-based virtual reality: Participants in this group will receive standard pain management care plus one session of immersive virtual reality (VR) using Oculus Go headsets. The session consists of viewing a nature-themed 360º video (e.g., beach, waterfall, songbirds) for approximately 8 minutes, accompanied by synchronized natural sounds. The VR experience is designed to promote distraction, relaxation, and emotional engagement with nature to support pain relief and emotional regulation. The equipment is sanitized between uses according to hospital infection control protocols.

Standard Pain Management: Participants in this group will receive the institution's standard pharmacological pain management, monitored and adjusted by the Pain Control Team using the hospital's electronic medical record system. This may include opioid and non-opioid analgesics according to clinical evaluation. No complementary interventions will be provided during the study period.

Study summary

This randomized clinical trial aims to evaluate the effectiveness of immersive nature-based virtual reality in managing chronic pain among oncology patients. The study seeks to expand non-pharmacological treatment options and contribute to the therapeutic arsenal available for chronic pain management in cancer care.The intervention utilizes immersive videos of diverse Brazilian natural environments to promote analgesic and emotional relief.

Eligibility

Primary outcome measure(s)

• Visual Analogic Scale for Pain — Immediately post-intervention for an unique virtual reality intervention
  Change from Baseline in self-reported pain intensity using a 0-10 Visual Analog Scale at post intervention. Will be applied the Visual Analogue Scale - VAS. It is one of the most used instruments for pain assessment with a score from 0 to 10 that allows the patient to evaluate the pain of the procedure through a visual analogue scale numbered from zero to ten, with zero no pain, ten being the worst pain ever felt in life.
• Frequency of analgesic administration Frequency of analgesic administration Frequency of analgesic administration — 24 hours post-intervention
  This outcome will assess the number of doses of analgesics administered to participants in the control and experimental groups within 24 hours following each intervention session. Analgesics include opioids, non-opioids, and adjuvant medications. Data will be collected from medical records.
• Total dosage of analgesics administered — 24 hours post-intervention
  This outcome will assess and compare the total dosage (in milligrams) of analgesics administered to participants in the control and experimental groups within 24 hours after each intervention session. The analysis will include opioids, non-opioids, and adjuvant medications. Data will be extracted from medical records.
• Type of analgesics administered — 24 hours post-intervention
  This outcome will identify and compare the types of analgesics (opioids, non-opioids, and adjuvant medications) used by participants in the control and experimental groups within 24 hours following each intervention session. Medication classes will be categorized based on pharmacological criteria.
