Platform Overview
Three Steps from Raw Data to Clinical Clarity
No data warehouse. No SQL training. No six-month implementation. Export your EHR data, upload it to Vizier, and ask your first question in under ten minutes.
Upload Your Export
Drag a CSV or Excel file exported from your EHR directly into Vizier. No reformatting required. Vizier accepts standard encounter exports, claims files, quality measure reports, and patient rosters exactly as your system produces them.
Ask a Question
Type your question the way you would ask a colleague: "What is our 30-day readmission rate for CHF patients?" or "Which providers have the highest no-show rates this quarter?" Vizier understands clinical terminology, ICD-10 codes, CPT codes, and quality measure language.
Get Your Answer
Vizier returns a chart, table, or narrative summary within seconds. Every answer cites the exact rows and columns it used. You can ask follow-up questions, drill into subgroups, or set a threshold alert so you are notified if the metric changes next month.
Schema Intelligence
Vizier Reads Your Columns, Not a Template
Every EHR exports data differently. Epic calls the column "AdmissionDateTime." Cerner calls it "Admit_DtTm." Allscripts uses "admitDate." A traditional analytics tool requires a data engineer to map these fields manually before you can run a single report.
Vizier's schema intelligence layer reads your file headers, samples the data types and value patterns, and automatically maps each column to a standard healthcare concept — patient identifier, encounter date, diagnosis code, procedure code, provider NPI, payer name, claim amount, and over 200 additional concepts.
The mapping is shown to you before any analysis runs, so you can confirm or correct it. Once confirmed, it is saved as your organization's schema profile — your next upload maps automatically.

Questions Quality Directors Actually Ask
Every example below is drawn from real queries submitted by clinical quality teams during pilot programs. The answers come back in under eight seconds.
"What is our 30-day readmission rate for CHF patients discharged in Q4?"
18.4% — above the national CMS benchmark of 15.2%. 34 of 185 discharges readmitted within 30 days.
Output: Rate card + patient list"Show me A1C trends for patients over 65 with a diagnosis of Type 2 diabetes."
Mean A1C declined from 8.7 to 7.9 over 12 months across 412 qualifying patients. 23% remain above 9.0.
Output: Trend line chart"Which three providers have the highest no-show rates this quarter?"
Dr. Okafor: 31%. Dr. Huang: 27%. Dr. Patel: 24%. Practice average: 18%.
Output: Ranked table"What is our claim denial rate for CPT 99214 billed to UnitedHealthcare?"
11.3% denial rate — 67 of 593 claims denied. Top denial reason: missing modifier (CO-4, 41%).
Output: Breakdown chart"Which DRGs have the longest average length of stay compared to geometric mean?"
DRG 291 (Heart Failure): +2.1 days over geometric mean. DRG 194 (COPD): +1.7 days.
Output: Comparison table"How many Medicare patients are due for their Annual Wellness Visit this month?"
214 patients — 89 with no AWV in 24+ months. Estimated recovery: $38,200 in preventive reimbursement.
Output: Action listThreshold Alerts
Set It Once. Know When It Matters.
After any query, click "Set Alert" to tell Vizier the threshold that matters to your team. When new data is uploaded, Vizier checks every active alert automatically and sends a notification only when a threshold is crossed.
Alerts are deliberate. You choose what to watch. The system does not generate noise — it generates signal. See our full threshold alert documentation for clinical examples including RPM billing compliance monitoring.
