The metaverse in healthcare, in practical terms, means virtual reality, mixed reality and 3D simulation used for specific clinical and training tasks, such as rehearsing surgery, treating pain and phobias, explaining procedures to patients and simulating hospital operations. Few of these projects need a blockchain, but every one of them must protect patient privacy, keep patients safe and prove a clinical benefit.
This page lists the healthcare uses of XR that have regulatory or research backing, and it covers the rules on medical devices and health data, the steps to build a clinical XR app, and realistic budgets.
What the evidence shows
Researchers have studied surgical simulation for years, and VR exposure therapy for phobias and PTSD has a long research history. In November 2021, the US FDA granted De Novo authorization to EaseVRx from AppliedVR, a decision that created a new device type: a virtual reality behavioral therapy device for pain relief. EaseVRx, now sold as RelieVRx, later received further clearances, including one in 2025 for a Pico G3 headset.
The FDA keeps a public list of AR and VR medical devices. In September 2026 the list held about 120 entries, including surgical navigation and viewing systems in radiology, orthopedics and neurology, as well as therapy systems.
Many "healthcare metaverse" pitches from 2021 and 2022 offered no regulatory decision or study of this kind, and did not say who the user was or which outcome would improve.
Uses of the metaverse in healthcare
| Use | What it involves | Typical hardware | Regulatory weight |
|---|---|---|---|
| Surgical and procedural training | Step-by-step simulations with scores, repeated without risk to patients | Standalone VR headsets, sometimes haptic devices | Low for education; higher if used to certify staff |
| Pain management and distraction | Immersive scenes and guided programs during procedures or for chronic pain | Standalone VR headsets | High when the product claims a therapeutic effect |
| Mental health and exposure therapy | Controlled exposure scenes that a clinician guides | VR headset with a clinician dashboard | High; needs clinical supervision |
| Rehabilitation | Game-like motor exercises with motion tracking and progress data | VR headset or camera-based tracking | Medium to high, depending on the claims |
| Patient education | 3D walkthroughs of anatomy, procedures and devices | Tablet, web 3D or headset | Low |
| Surgical planning | 3D models from CT or MRI scans viewed in mixed reality | Mixed-reality headsets and workstations | Can be a regulated medical device |
| Hospital digital twins | Simulations of patient flow, bed capacity and equipment placement | Desktop software on Omniverse or Unreal | Low |
Regulation and privacy
Medical device status
In the US, the FDA may regulate software that diagnoses, treats or reduces a condition as software as a medical device, and in the EU the Medical Device Regulation applies. Wellness and education products usually fall outside both the FDA and EU device rules, but marketing language can still move a product into the regulated group, so the intended use should be decided and written down at the start.
Health data
HIPAA applies when you work with US covered entities and handle protected health information. The HIPAA rules require business associate agreements, access controls and audit logs, and in Europe, health data is a special category under GDPR.
Headset sensors collect new kinds of sensitive data, since eye tracking, voice, movement patterns and room scans can all reveal health information. Clinical XR teams therefore take four precautions:
- Process sensor data on the headset where possible.
- Keep raw tracking data out of analytics tools.
- Manage clinic headsets with device-management software.
- Set cleaning procedures for shared headsets.
Building a clinical XR application
- Define the outcome with clinicians. State what changes for the patient or trainee and how the team will measure it.
- Prototype with real users. Include patients who may be elderly, ill or prone to motion sickness. Motion sickness or discomfort can make a patient stop the session, so comfort decides whether the treatment works.
- Build the clinician side. Clinicians need session setup, progress tracking and controls to pause or adjust exposure, and reports must fit into existing records.
- Connect to health records. Use standards such as HL7 FHIR where the app exchanges data with records systems. The guide to EMR and EHR software development covers records integration.
- Validate the product. Run pilots, and run formal studies for any therapeutic claim.
- Deploy and support the devices. Plan for charging, cleaning, software updates and staff training in each clinic.
Many clinical VR apps on standalone headsets are built in Unity, while web 3D suits patient education that must reach phones and laptops.
Blockchain in a healthcare metaverse
Healthcare pitches often add a blockchain, but patient data must not go on a public chain, even in encrypted form, because nobody can delete data from a public chain and future computers may break today's encryption. A few narrow uses can work:
- Tamper-evident audit trails shared across organizations.
- Records of patient consent.
- Verification of clinician credentials.
- Tracking drugs through the supply chain.
The article on blockchain in healthcare and the guide to blockchain for pharma cover these uses, but an XR training or therapy app almost always runs best on a normal, well-secured backend.
Costs and timelines
A small team can build a focused training module or patient-education app in about three to six months, with two engine developers, a 3D artist with medical illustration skills, a clinical advisor and a tester. A therapy product that needs regulatory clearance is a much larger effort, because its quality management system, clinical studies and documentation often cost more and take longer than the software.
The guide to metaverse application development covers how immersive training and digital twins are built in general.
Frequently asked questions
How is the metaverse used in healthcare?
Hospitals and schools use VR and mixed reality for surgical and nursing training, distraction during painful procedures, rehabilitation exercises, exposure therapy and patient education. Surgeons also view 3D models from scans in mixed reality to plan operations.
Does a VR therapy app need FDA clearance?
The answer depends on the app's claims. An app that claims to treat or diagnose a condition may be a regulated medical device, while a wellness or education app usually is not.
Should patient data be stored on a blockchain?
No. Public chains are permanent and visible to anyone, which conflicts with privacy law and with the right to deletion. Health data belongs in secure conventional systems, though a chain can hold proofs or audit records that contain no health data.
What hardware should a clinic use?
Most clinics start with standalone headsets under enterprise device management, which need no PC and can be locked to specific apps. Mixed-reality headsets suit surgical planning and anatomy viewing.
