研究概览
简要总结
ASCEND-MA is an embedded, health-services study of at-risk Medicare Advantage members attributed to Intermountain Health in Utah. Participants are quasi-randomized based on their medical-record-number parity to either AI-supported, nurse-reviewed proactive care navigation or usual care. The study will evaluate whether the program changes cumulative payor-paid healthcare spending over 12 months.
详细描述
An additional ancillary, separately consented consumer-experience sub-study will sample roughly 45 intervention-arm participants for surveys and interviews about the acceptability, burden, and perceived usefulness of the care-navigation workflow.

研究组 & 干预措施
AI Supported Rising Risk Care Navigation
Participants receive routine clinical care plus the AI Supported Rising Risk Care Navigation strategy. The strategy periodically assesses for care opportunities; every candidate nudge undergoes human clinical review before routing or outreach, and no outreach occurs when no clinically appropriate action is identified
干预措施: AI-Supported Rising-Risk Care Navigation (Other)
Usual Care
Participants receive routine clinical care and existing care-management services under standard eligibility and operating rules. The study introduces no AI-supported care-navigation nudges for this arm and withholds no otherwise available care because of assignment
结局指标
