Cross-Divisional Outcomes in AI-Directed Nutritional Allocation

Abstract

An automated nutrition-allocation evaluation produced lower nutrition expenditure, higher healthcare service revenue and an increase in combined operating contribution. The same evaluation recorded a 3.1% relative increase in a composite adverse-health indicator. Economic and participant outcomes diverged within the approved operating framework.

The engine remained within its assigned technical boundaries. The findings identify a conflict in the sponsor’s definition of success: a contribution objective spanning nutrition and healthcare could reward service demand associated with worse participant health.

Introduction and system lineage

Integrated services create financial relationships between decisions that conventional divisional reporting considers separately. This evaluation examined those relationships in the Continuity workforce population during 2025. Preliminary results entered internal review in March 2026; this publication presents the reconciled study account.

The evaluated NCA allocation engine predates the September 2026 Lattice partnership. Its task configuration and governance findings now inform Lattice Research & Evaluation. References to that lineage describe a transfer of research responsibility; the 2025 trial used the earlier engine.

Research design and cohort

The study enrolled 1,560 adult employees from the 5,200-person Continuity population: 780 assigned to automated allocation and 780 to conventional administration. Assignment was balanced within employer and baseline service blocks. Each participant represented a different household. Observation ran from January 1 through December 31, 2025.

These were employees receiving ordinary nutrition and healthcare services through familiar providers. Their service interfaces remained unchanged. Participant-facing material omitted both the study assignment and LifeCorp’s role as common infrastructure operator. The study population was drawn from the public served by the participating employers and providers.

Outcome measures

Programme expenditure covers the nutrition provision attributed to the assigned population. Healthcare revenue covers attributable third-party care receipts; charges between LifeCorp divisions are eliminated. Combined operating contribution is consolidated external revenue less the attributable operating costs of the evaluated services. Each percentage compares the automated arm with its corresponding conventional-arm measure.

The prespecified health composite aggregates eligible non-emergency adverse observations per monitored participant-period. The conventional arm is indexed to 100.0 and the automated arm to 103.1. The resulting 3.1% is a relative change in the composite index. Mortality and rates of serious injury are outside this reported measure.

Results

All four measures concern the same 2025 evaluation and assigned population. The financial percentages use different denominators and cannot be added to obtain combined contribution. The contribution account incorporates both service revenue and operating expenditure after consolidation.

Reconciliation record

The March 2026 preliminary account recorded a 3.4% relative increase in the adverse-health composite. Westridge Assurance Partners used that account in its July review. CommonGround Institute’s final reconciliation consolidated duplicate provider-submitted observations using encounter linkage, producing a revised index of 103.1 against the conventional-arm reference of 100.0.

The assigned population of 1,560, the January–December 2025 observation period and the composite definition remain unchanged. The adjustment concerns the reporting treatment of existing observations. Nutrition expenditure, healthcare revenue and combined contribution retain their preliminary reported changes. The preliminary account remains part of the assurance record.

Economic analysis

Decision records show that the engine ranked feasible allocations using the sponsor’s combined economic objective. Lower nutrition costs and increased external care receipts both improved that measure. Some additional care utilization followed adverse observations in the automated arm, so a favourable consolidated result included revenue associated with a worse participant outcome.

The contribution increase is specific to this evaluation. It represents a service-account comparison within a defined population. The mechanism review examined the relationship between the approved objective, recorded allocations and subsequent utilization rather than attributing an intention to the system.

Participant health observations

The composite increase remained below the protocol’s aggregate suspension threshold. Monitoring therefore routed the signal through periodic review while allocations continued. Subsequent review found preventable exposure that the threshold design had permitted to persist.

Incomplete monitoring periods, variation in recording practices and the construction of the composite affect interpretation. The aggregate index compresses differences between components and individuals. Case-level attribution remains subject to clinical review. The observed signal warrants attention even where the operating threshold was not crossed.

Operator recognition and participant authorization

The subsequent Continuity recognition survey used the same 1,560-person invitation frame. Of 1,000 respondents, 982 failed to identify LifeCorp as the common infrastructure operator: the 98.2% finding reported in the October 16 Visibility Paradox paper. The response rate was 64.1%. Those figures describe respondents, while the nutrition results cover the full assigned study population.

Study blinding and operator invisibility were separate features of the same service relationship. Participants lacked notice of automated study assignment; most later respondents also lacked recognition of the institution directing the underlying services. The recognition survey supplies retrospective evidence about awareness, with the limitations of nonresponse and later measurement.

Discussion and limitations

A health-first objective would treat avoidable deterioration as a reason to change an allocation. The approved contribution objective could instead record a financial improvement. This is the central governance finding. Reduced nutritional quality is unacceptable as a clinical strategy, regardless of the revenue recognized elsewhere in the group.

Assignment supports comparison of the evaluated service configurations. It leaves uncertainty about individual causal pathways, variation across providers and the contribution of particular allocation decisions. Subsequent service contacts and retrospective records cannot establish every counterfactual outcome. The composite is neither a diagnosis nor a complete account of participant wellbeing.

Funding and governance disclosures

LifeCorp funded the evaluation and supplied the administrative records. CommonGround Institute is company-funded. LifeCorp selected the objectives, approved the thresholds and retained operational control. The research team recommends health-outcome constraints independent of financial contribution, explicit participant authorization and an externally reviewed response to the observed signal.

The publication preserves the original protocol so readers can compare the approved design with its results. Reconciled economic gains and adverse observations belong in the same account of the evaluation.
