Brief Summary
The Health Ahead Comparative Effectiveness Study is a pragmatic, parallel-arm interventional platform that systematically compares successive changes to preventive health screening on the path toward a fully automated screening system deployable in any environment, including the most isolated and resource-limited communities. Each change is isolated as a single variable against current practice, and every comparison is evaluated with a common set of engagement, behavior-change, experience, cost, and longitudinal outcome measures, so results accumulate on a consistent yardstick across the life of the platform. The first comparison evaluates AI-assisted versus human-only interpretation ("reads") of screening data. Subsequent pre-planned comparisons, added by protocol amendment, evaluate static versus interactive personalized report delivery; mobile community versus fixed laboratory screening; and a hybrid medical-droid-plus-human delivery model versus human-only screening.

Outcome Measures
Primary Outcomes (1)
Health Awareness and Action (Non-Inferiority)
Change from baseline in health awareness and action score, measured by the Health Awareness and Action 6-item questionnaire (HAA-6) or its successor instrument, specified and locked in the comparison's Statistical Analysis Plan before first allocation. Change is compared between the experimental arm and the active comparator arm. Non-inferiority is assessed with a one-sided test at the 6-12-month timepoint against a margin pre-specified in the comparison's Statistical Analysis Plan and locked before any analysis of comparison data.
Baseline (intake, completed at home before the screening visit); 1-2 weeks after screening, at report delivery; 6-12-month follow-up; then periodically from enrollment until death, up to 100 years.
Secondary Outcomes (29)
Health Awareness and Action (Superiority)
Baseline (intake, completed at home before the screening visit); 1-2 weeks after screening, at report delivery; 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.

Human-Only Screening Interpretation
ACTIVE COMPARATORParticipants receive comprehensive preventive health screening under the standard of care for the comparison in progress. In the active comparison, all screening data, images, tracings, and laboratory results are interpreted by the physician of record and qualified clinical staff under physician supervision, without AI decision support.
AI-Assisted Screening Interpretation (AI Reads)
EXPERIMENTALParticipants receive identical screening with one element modified: the single variable under test in the comparison in progress. In the active comparison, models produce AI-generated reads of the acquired data, presented to the physician of record as a clinical aid. The physician reviews each read, records a structured judgment before sign-off, and produces and signs the released interpretation. The comparison runs in two screening-complexity strata, with a single general model in the simple stratum and a general model plus at least three domain-specific models in the comprehensive stratum.
Interventions
All acquired screening data, images, tracings, and laboratory results are interpreted by the physician of record and qualified clinical staff under physician supervision, by standard practice and without AI decision support. This is the current standard of care and the active comparator.
An AI-generated read of the acquired screening battery is produced and presented to the physician of record as a clinical aid. All models used are third-party models, executed unmodified on Longevity Metrics clinical infrastructure. The physician reviews each read, records a structured judgment before sign-off, and then produces and signs the released interpretation, which may adopt, modify, or reject any read.

Data Sharing
- IPD Sharing
- Will not share
Individual participant data are not shared. The complete participant record includes facial and voice recordings, genomic data, and neighborhood-resolution geography, and cannot be de-identified; it is never released. Identifiable data are accessed only by approved researchers working within Longevity Metrics secure facilities under data use agreements, with no data removed. Specific derived, aggregate, and statistical outputs are de-identified to HIPAA Safe Harbor standards and may be published, shared with collaborators, or contributed to open-access research databases. Models, risk estimates, and analytic findings derived from the research data may be provided to external organizations or used commercially; no participant record and no dataset containing participant data is transferred.
