An actuarial analysis completed using Summus cases matched to cohorts from the MarketScan database, the industry-standard for employer claims, validated $30,474 in positive medical cost impact for member journeys with changed treatment paths.

## About Summus

Summus is the only physician-led, multi-specialty platform built to support every member’s care journey, from rising-risk to high-cost, complex diagnoses.

A national ecosystem of Summus MDs supports and orchestrates member journeys across the most complicated and expensive conditions in healthcare. We close the gaps in fragmented care by providing whole-person, longitudinal support so that members better understand multiple options, sequence treatment choices, and focus on the right specialties involved at the moments when decisions matter most. Summus helps employers and health plans manage costs, deliver meaningful outcomes, and improve satisfaction.

## What’s in the Paper

![Report cover](https://go.summusglobal.com/hs-fs/hubfs/Report%20cover.png?width=726&name=Report%20cover.png "Report cover")

- **Reproducibility of Methodology**Arbital Health performed an independent evaluation, recreating the Summus model previously validated for changed treatment path utilizing standard industry employer claims data.
- **Reliability of Savings**Application of the model with 109 recent Summus members demonstrated ~3% variation across multiple time windows constituting an episode of care, for both allowed and paid claims.
- **Future Directions of Actuarial Review**Will include cost impact on pharmaceutical spend and refinement of diagnoses, for which Summus trended positive in this analysis.

## Key Takeaway

This evaluation offers independently validated evidence highlighting how doctor-guided care orchestration and navigation across complex conditions drives real financial impact, showing steady results regardless of timeframes or cost metrics.
