New Milliman Report Confirms RADAR Algorithm's Accuracy in Cognitive Health

In a groundbreaking revelation, Together Senior Health, part of Linus Health, has announced insights from a recent report by Milliman, a top actuarial firm, affirming the proficiency of their RADAR algorithm in detecting undiagnosed cognitive impairments. This crucial evaluation indicates a significant step forward in how healthcare systems can identify individuals at high risk of conditions such as Alzheimer's and dementia, using claims-based data.

Understanding the RADAR Algorithm

The RADAR (Risk of Alzheimer's and Dementia AlgoRithm) family of models was initially built upon electronic health record data. However, the latest findings reveal its adaptability when utilizing claims data. As healthcare providers grapple with the demands of patient care, especially in primary care settings, RADAR provides a streamlined method for swiftly identifying patients who warrant immediate cognitive screenings. According to Dr. Deborah E. Barnes, co-founder of Together, the algorithm allows healthcare professionals to prioritize individuals who may greatly benefit from early intervention.

Key Findings from the Milliman Report

The Milliman report underscores the positive predictive value of the new RADAR models, stating that “all models perform reasonably well” across various statistical assessments, including sensitivity and specificity. Additionally, the report indicates that by refining the model to incorporate new predictors, the predictive accuracy for undiagnosed dementia risks significantly improves. Milliman’s assessment concluded that this new adaptability not only enhances the algorithm's performance but also emphasizes the potential of comprehensive and flexible predictors, resulting in more precise evaluations and outcomes.

John Showalter, Chief Strategy Officer at Linus Health, commented on the algorithm's predictive performance, noting it is “twice as effective as mammography and three times better than colonoscopy” for identifying cognitive impairments. In contrast to traditional screenings for physical diseases that can require significant patient involvement, RADAR operates without any discomfort or extensive resource expenditure, marking it as a cost-effective solution for healthcare providers and payers alike.

Transforming Healthcare Approaches

Mike Butler, a former president of Providence Health and current board director at Linus Health, emphasized RADAR's transformative potential, especially for Medicare Advantage plans and value-based care models. He remarked that the algorithm not only enhances diagnostic accuracy but also supports healthcare systems in delivering proactive and patient-centered care. With RADAR, providers can significantly improve operational efficiency, patient outcomes, and cost management in cognitive assessment protocols.

In light of the rapid integration of technology into healthcare, the implications of RADAR’s success are profound. By equipping healthcare providers with robust tools for cognitive assessments, Linus Health aims to foster a future wherein cognitive and brain health issues are identified and addressed proactively, leading to improved quality of care across populations.

Conclusion

The Milliman report marks a pivotal moment for Together Senior Health and the RADAR algorithm, highlighting its critical role in transforming cognitive health assessments. As the industry shifts towards data-driven models for proactive healthcare, RADAR stands at the forefront, promising a brighter future for individuals facing the challenges of cognitive decline. Such innovations not only ensure timely interventions but also pave the way for healthier aging and enhanced quality of life for vulnerable populations.
