MedScrub vs ThetaRho (2026)
Both give organizations a layer for working with patient data and AI, from different angles. MedScrub removes the patient from the data before a model sees it. A proxy strips all eighteen HIPAA identifiers, sends de identified content to the model the customer chooses, and restores identity in the answer, with self hosting and local models supported. ThetaRho sells a clinical intelligence platform in three layers, each available on its own. Its data layer parses documents, matches and de duplicates patients, and converts data from EHRs, CommonWell and TEFCA exchanges, wearables and apps into FHIR R4 annotated with standard terminologies. Its AI layer adds semantic search and cited question answering, and its RISA application, on the athenahealth Marketplace since October 2025, writes visit summaries and drafts notes, referral summaries and prior authorization justifications for physician approval. If your failure mode is identifiable data reaching an outside model, start with MedScrub. If it is patient data scattered across sources before any model can use it, start with ThetaRho.
- Identifiers are stripped by a proxy before content reaches any model, and the substitution is reversible, so the answer comes back with identity restored.
- GPT-4, Claude, Gemini, Mistral and local models under Ollama are named as supported targets, and the proxy is also sold as an HTTP API and an MCP server for developers.
- A clinician product pulls conditions, labs, vitals, medications and imaging from the EHR into a repository the customer owns and writes a visit summary before the patient arrives.
- The data layer converts records from athenahealth, Epic, CommonWell, TEFCA, wearables, apps and PubMed into FHIR R4, annotated with RxNorm, LOINC, SNOMED CT, ICD-10 and MeSH.
- RISA, built for athenaOne, retrieves notes, labs, imaging and outside records on request and marks each medical concept green when it traces to the patient record and orange when it does not.
- The stack is sold through APIs or as an appliance inside the customer's security perimeter, and every RISA action is queued for physician approval.

MedScrub strips the patient out of the records first, sends the de identified content to whichever model the customer chooses, and re identifies the answer on the way back. All eighteen HIPAA identifiers are removed by a proxy before data reaches any model, the substitution is reversible, and the company reports 78 percent token cost savings as a side effect of the compression involved.

ThetaRho sells a clinical intelligence platform in three layers and will sell any of them on its own. The data integration layer parses documents, matches and de-duplicates patients, and converts data from EHRs (athenahealth and Epic named), health exchanges reached through CommonWell and TEFCA, wearables and apps, and research sources such as PubMed into FHIR R4, annotated with RxNorm, LOINC, SNOMED CT, ICD-10 and MeSH.

Questions buyers ask
How do MedScrub and ThetaRho handle patient data?
For MedScrub, all eighteen HIPAA identifiers are removed before content reaches any model, so a consumer or frontier model never receives identifiable data.
With ThetaRho, the company says HIPAA and SOC 2 compliance, full audit trails and a privacy-first architecture are its foundation, and offers the platform as a stand-alone appliance inside the customer's security perimeter. The privacy policy link in the site footer returns a 404, and nothing states retention, training use or de-identification for records the hosted API processes, or for wearable and device data it ingests.

MedScrub's details are unverified, and it publishes no price, business associate terms or figure for how reliably its proxy finds identifiers. ThetaRho publishes no price and no business associate terms, and claims SOC 2 compliance without stating the type or scope. RISA's chart review, documentation and patient specific research are live, orders and referrals come next, and decision support is listed as future work. ThetaRho's figures of up to five minutes saved per visit carry no method, and no clinic is named.
