TheraDoc vs VigiLanz (2026)
The two incumbent clinical surveillance platforms in American hospitals, and a comparison many pharmacy directors run at renewal. Both watch live laboratory, microbiology, pharmacy and admission feeds. Both raise alerts for stewardship, infection prevention and pharmacy surveillance, and route them to a pharmacist rather than acting on an order. Both run on rules the hospital's own staff configure, and both add a partner's Bayesian dosing model: DoseMeRx inside VigiLanz, InsightRX Nova inside TheraDoc. VigiLanz reaches wider by setting, with separate products for small hospitals, acute care and ambulatory care, and Inovalon publishes its business associate agreement in full. TheraDoc is broader inside the hospital, covering mandatory infection reporting, stewardship, pharmacy surveillance and anticoagulation in one platform. Since both cores are rules, the diligence question is how the rules are validated and retired, not model accuracy.
- One platform covers infection prevention with mandatory reporting to the national surveillance network, antimicrobial stewardship, pharmacy surveillance and anticoagulation monitoring.
- The product is described plainly: Premier makes no AI claim for its rules engine and names the dosing model it integrates.
- Alerts route to a clinical pharmacist or infection preventionist who investigates, and the platform never touches an order.
- Coverage spans small and critical access hospitals, acute care and a separate ambulatory surveillance product.
- It ingests near real time clinical data regardless of which record system produced it, so a mixed estate is not an obstacle.
- Inovalon publishes its business associate agreement in full, and one set of terms covers every tier.

Questions buyers ask
How are TheraDoc and VigiLanz priced and sold?
For TheraDoc, two commercial dynamics bear on renewal. The parent completed a take private transaction valued at $2.6 billion after reporting an eleven percent revenue decline in fiscal 2025, and private equity ownership typically brings a review of product pricing and portfolio scope, so renewal terms may not carry over unchanged.
With VigiLanz, the ONC certification disclosure on the same page states that the certified product requires a one time implementation fee and an annual licensing fee. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 20, 2026. No vendor pays for placement.

Inovalon describes VigiLanz as flexible, rule based AI and as AI powered surveillance. The engine evaluates configurable rules, and its learned component is the DoseMeRx dosing add on. Premier makes no AI claim for TheraDoc. A rules engine is transparent by construction, which changes what to ask for: a rule validation method rather than model accuracy. Neither publishes performance by patient characteristic, a rule validation method or a monitoring statement after deployment.
Each names an ONC Health IT certification, which tests software features, and neither names an audit of how it operates security, such as SOC 2. Neither publishes a price. Inovalon sets out VigiLanz's tiers by facility type; Premier publishes nothing on how TheraDoc is sold.
