Health Ahead Comparative Effectiveness Study (HACE)
Health Ahead: Sequential Comparative-Effectiveness Studies Toward Automated, Universally Deployable Preventive Health Screening
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.
調査の概要

詳細な説明
Access to comprehensive preventive health screening is profoundly unequal. Geographic, economic, and systemic barriers leave medically underserved populations, including rural, frontier, and isolated communities, with little or no access to screening deep enough to identify disease before symptoms occur. The long-term aim is a fully automated preventive screening system deployable anywhere people live. Reaching it safely requires testing each change to the screening model one variable at a time, against current practice.
The study is therefore a standing sequential comparative-effectiveness platform. Each comparison isolates a single change, holds every other element of the screening experience constant, and is evaluated against the same core outcome set. As one comparison concludes, the next opens by protocol amendment.
Two principles govern every comparison. First, allocation is randomized wherever participant-level random assignment is feasible, non-randomized only where it is not, as in comparisons of screening location. Second, every comparison is registered with non-inferiority as the primary hypothesis: each step toward a more automated, more broadly deployable model must show it does not degrade outcomes relative to current practice by more than a pre-specified margin. Superiority is a pre-specified secondary in a hierarchical, gatekeeping sequence. No numeric margins are fixed at registration; each is set per comparison by a rule anchored to a validated minimal clinically important difference where one exists, and locked before that comparison's data are analyzed. Each non-inferiority comparison reports intention-to-treat and per-protocol analyses, and a conclusion requires agreement between them.
The active comparison and the planned comparison sequence are set out below. Comparison 1 (active): AI-assisted versus human-only interpretation ("reads") of screening data. Arms complete identical screening for their visit type and differ only in whether the acquired data receive an AI-generated read. A physician of record reviews and signs every released interpretation in all arms. The comparison runs in two strata by screening complexity, randomized 1:1 within each. The primary contrast combines the strata; each stratum is also analyzed separately. The primary hypothesis is that AI-assisted interpretation is non-inferior to human-only interpretation on health activation.
Planned comparison - static versus interactive personalized health report delivery. Both arms complete identical screening and differ only in the report received. The interactive report lets participants adjust their own behaviors and diagnostic inputs in real time and see the projected effect on composite scores, estimated biological age, and aging trajectory. Randomized.
Planned comparison - mobile community screening versus fixed laboratory screening in medically underserved populations. Because assignment follows the site at which a participant presents, this comparison is not randomized at the participant level.
Planned comparison - a hybrid delivery model combining medical droids, one registered nurse, and remote physician oversight, versus human-only screening.
Future comparison - fully automated screening performed by medical droids with remote physician review, versus the hybrid model.
Future comparison - reduced-capture screening versus the full screening battery, testing how far the acquired input can be reduced while preserving what the screening delivers.
This study is one of four that compound into one system. The 100-Year Human Aging Study (NCT07563777) supplies the clinical data and validates what it means for health, disease, disability, and death. The Human Observatory Study (NCT07646782) does the same with sociodemographic and environmental data, and receives each model's geographic residuals. The Longevity Metrics AI/ML Development Study (NCT pending approval) builds the models that make automation, prediction, and broad utilization possible. This study moves the screening toward increasing automation and mobility while maintaining quality.

アクティブコンパレータ：Human-Only Screening Interpretation
Participants 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.
|
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.
|
|
実験的：AI-Assisted Screening Interpretation (AI Reads)
Participants 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.
|
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.

|
Primary Barrier to Non-Completion of Recommended Changes
時間枠：Baseline, 6-12-month follow-up, then periodically from enrollment until death, up to 100 years.
|
For each provider-recommended change a participant reports not completing, the participant identifies the single main barrier using a fixed-choice item adapted to that recommendation ("What is the main thing getting in the way of [recommendation]?").
Response options: Time; Money or cost; Access to care or services; Stress or mental health; Sleep; Addiction or substance use; Physical limitations, pain, or symptoms; Knowledge (not sure what to do); Motivation; Habits or routines; Family or relationship demands; Other (free text).
The metric is the distribution of selected barriers across non-completed recommendations, compared between arms.

Participant Satisfaction - Longevity Metrics Post-Screening Satisfaction Questionnaire (6-item), Composite Score
時間枠：1 to 2 weeks after health screening (at report delivery)
|
Participant satisfaction measured with the Longevity Metrics Post-Screening Satisfaction Questionnaire, a 6-item self-report instrument administered after the participant receives their screening report.
Each item is rated on a 1-10 linear scale; items cover perceived value of the report, satisfaction with the tester, the screening, and the data/report/recommendations, and likelihood to recommend Longevity Metrics.
A composite score is calculated as the sum of all items (minimum 6, maximum 60); higher scores indicate greater satisfaction.

Complexity-Adjusted Cost-Effectiveness
時間枠：6-12-month follow-up, then periodically from enrollment until death, up to 100 years.
|
Complexity-adjusted cost, computed as total direct costs ÷ (screening complexity weight × participants completing screening), where the complexity weight reflects the scope and intensity of the screening battery delivered (e.g., single-modality DEXA versus the full multi-system report-card battery), so that a simpler, lower-cost screen is not credited as artificially more efficient than a broader battery that delivers more.
An incremental cost-effectiveness ratio compares complexity-adjusted cost against improvement in the primary endpoint.

Participant Follow-up and Retention
時間枠：6-12-month follow-up, then periodically from enrollment until death, up to 100 years.
|
Retention and follow-up completion across the lifelong cohort, compared between arms, assessed by: study retention (proportion of enrolled participants remaining active versus withdrawn or lost to follow-up); follow-up questionnaire completion (proportion completing each scheduled follow-up survey); and in-person re-screening return (proportion returning to the laboratory or mobile site for scheduled repeat testing).
Initial follow-up occurs at 6-12 months; follow-up continues for life thereafter, enabling longitudinal ascertainment of chronic disease, adverse health outcomes, and mortality.
Differential retention between arms is monitored as a potential source of bias in non-inferiority comparisons.
