A web-based tool for exploring VistA/MUMPS global structures using real VEHU test data.
Live demo: openvista.cc/app
- Browse 193,900+ clinical records from VistA VEHU across 15 packages
- View raw MUMPS globals with piece-by-piece breakdowns in a side panel
- Write vitals, problems, and allergies directly to live MUMPS globals
- See FileMan date formats, pointer resolution, IEN allocation in action
The app shows a clinical patient view on the left with a MUMPS globals panel on the right, displaying the raw ^GMR(120.5), ^DPT, ^AUPNPROB structures behind the clinical data.
- Frontend: Single-file HTML/CSS/JS
- Backend: Python/Flask with SQLAlchemy Core
- Database: PostgreSQL 17 (bulk reads) + live MUMPS via YottaDB (writes and live panel)
- MUMPS: VistA VEHU on YottaDB (OSEHRA VEHU Docker image)
| Package | Global | Records |
|---|---|---|
| Patients | ^DPT | Demographics, service history |
| Problems | ^AUPNPROB | Problem list with status tracking |
| Vitals | ^GMR(120.5) | Vital signs with type resolution |
| Allergies | ^GMR(120.8) | Allergy/adverse reactions |
| Pharmacy | ^PSRX | Prescriptions, refills, status |
| Labs | ^LR | Lab results, panels, ranges |
| Orders | ^OR(100) | CPOE orders with status |
| Notes | ^TIU(8925) | TIU clinical documents |
| Consults | ^GMR(123) | Consult requests and results |
| Radiology | ^RADPT | Rad exams and reports |
| Scheduling | ^SCE | Appointments |
| Surgery | ^SRF | Surgical cases |
| Immunizations | ^AUPNIMM | Vaccination records |
| Mental Health | ^YTT | MH instruments and scores |
| PCE | ^AUPNVSIT | Visits, procedures, diagnoses |
The app supports writing to live MUMPS globals for:
- Vitals — Enter vital signs →
^GMR(120.5) - Problems — Add/inactivate problems →
^AUPNPROB - Allergies — Add allergy records →
^GMR(120.8)
After each write, data is read back from MUMPS to verify persistence.
- Python 3.10+
- PostgreSQL 17

NOT intended for clinical use. Write operations bypass FileMan validation and do not maintain cross-references, audit trails, or business rule enforcement. IEN allocation is simplified and does not use FileMan's native allocation.
For production VistA integration, use the RPC Broker, FileMan API (^DIE, ^DIK), or a certified FHIR adapter.
