Brief Summary

The Health Ahead Comparative Effectiveness Study is a pragmatic, parallel-arm interventional platform that systematically compares successive changes to preventive health screening - each isolated as a single variable against current practice - on the path toward a fully automated screening system deployable in any environment, including the most isolated and resource-limited communities. Each comparison is evaluated with a common set of engagement, behavior-change, experience, cost, and longitudinal outcome measures, allowing results to accumulate on a consistent yardstick across the life of the platform. The first comparison evaluates static versus interactive personalized health report delivery. Subsequent pre-planned comparisons, added by protocol amendment, evaluate mobile community versus fixed laboratory screening; and a hybrid medical-droid plus human-delivery model versus human-only screening. All participants are simultaneously enrolled in the 100-Year Human Aging Study and the Human Observatory Study, contributing individual longitudinal and population-level causal inference data through those protocols.

Outcome Measures

Primary Outcomes (1)

  • Health Activation and Engagement (Non-Inferiority)

    Change from baseline in health activation score, measured by a validated open-source instrument, compared between the static report arm (Arm A) and the interactive report arm (Arm B). Non-inferiority of the interactive arm is assessed with a one-sided non-inferiority test against a non-inferiority margin pre-specified in the comparison's Statistical Analysis Plan and locked before any analysis of comparison data.

    Baseline, 6-12-month follow-up, then periodically from enrollment until death, up to 100 years.

Secondary Outcomes (23)

  • Health Activation and Engagement (Superiority)

    Baseline, 6-12-month follow-up, then periodically from enrollment until death, up to 100 years.

  • Report Efficacy and Utilization

    Baseline, 6-12-month follow-up, then periodically from enrollment until death, up to 100 years.

  • Unintended Consequences and Psychological Impact

    Baseline, 6-12-month follow-up, then periodically from enrollment until death, up to 100 years.

  • Completion of Provider-Recommended Health Behavior Changes

    Baseline, 6-12-month follow-up, then periodically from enrollment until death, up to 100 years.

  • Primary Barrier to Non-Completion of Recommended Changes

    Baseline, 6-12-month follow-up, then periodically from enrollment until death, up to 100 years.

  • +18 more secondary outcomes

Intervention Model
FACTORIAL
Model Details: This is a multi-domain comparative-effectiveness platform study of how health screening is delivered. Each domain compares two conditions: (1) Report format - static vs. interactive personalized health report; (2) Screening setting - fixed-site vs. mobile community-based screening; (3) Delivery model - human-delivered vs. hybrid medical-droid-and-human-delivered screening. Domains open over the course of the study and additional domains may be added by amendment. A participant may receive interventions from more than one domain. Allocation is randomized within a domain whenever operationally feasible (e.g., report format) and otherwise follows setting and availability (e.g., screening setting determined by location and participant presentation). Allocation procedures for the delivery-model domain will be finalized by protocol amendment.
