Ellipsis Health

What does a Sage call cover?

The vendor describes Sage as making "fully autonomous virtual care management calls," around the clock. The product and FAQ pages list enrollment, benefits and eligibility checks, health risk assessments, care and discharge assessments, HCAHPS and satisfaction surveys, adherence, transitions of care and "Friday tuck-ins."

Oversight is described as a "human-in-the-loop approach for complex cases." The vendor says a team of physicians, nurses and care managers validates every Sage update before deployment. The pages describe no crisis or suicidality protocol, and escalation to nurses does not appear on the product page. Sage is "multilingual," with no language named.

Which papers carry the Ellipsis name?

Four papers study the company's speech technology, all with Ellipsis employees among the authors and conflict-of-interest statements.

• A 2022 Frontiers in Psychology study (PMID 35478769) tested the Ellipsis Health App against PHQ-8 and GAD-7 in a senior population and reported an AUC of 0.82 with 61% protocol completion.
• A 2022 Cancers study (PMID 35205663) covers a speech-based distress screening app for adolescents and young adults.
• A 2025 JMIR AI study (PMID 40605836) is a retrospective analysis of speech and language models for depression severity in a payor-provider system, using Ellipsis algorithms.
• A 2026 JMIR Research Protocols paper (PMID 41678797) covers feasibility of the eCARE app for depression and anxiety monitoring in family caregivers of cancer patients.

None evaluates Sage calls. The vendor's own results, 60% less administrative work, 4x ROI and 6x faster enrollment, carry no sources.

What does it say about security and integration?

Ellipsis lists HIPAA and GDPR compliance, SOC 2 Type 2 and annual third-party audits. Its FAQ says the AI platform "has achieved HITRUST Certification." Sage "can connect with EHR and case management systems" through an API-first design.

The verdict

A plan or system with assessment, enrollment and post-discharge calls to place at scale will find the call types spelled out, and a clinic wanting an inbound symptom line will not.
