What Remains if Site-of-Care Optimization Scales?

Review Supplement

Thomas Persichetti

Part of the Core Review

Site-of-care optimization begins as a local purchaser strategy. A purchaser identifies an economic opportunity, changes where or how care is delivered, and captures some portion of the resulting difference.

As adoption expands, those local decisions begin to change the economic environment around them. More volume moves. Revenue shifts among participants. Alternative delivery capacity may grow. Providers and other counterparties respond to the changed incentives. At sufficient scale, the response can begin to alter the opportunity that originally motivated the intervention.

The harder issue is how far those changes travel through the larger health care system.

Scale creates a broader economic response

The effects of widespread site-of-care optimization are unlikely to be a simple aggregation of individual purchaser savings.

At the purchaser level, the economic object is relatively contained: spending moved from one arrangement to another at a lower expected cost. At larger scale, the cumulative movement changes the incentives facing organizations whose economics extend well beyond the targeted service.

Hospitals and health systems operate across multiple service lines, payer relationships, facilities and markets. Infusion may represent an economically important activity, but changes in infusion revenue occur within that much larger structure.

As a result, reduced spending in one service line can produce different combinations of cost removal, cost transfer and resource reallocation. Some resources may leave the system. Others may migrate to different sites or services. Revenue pressure may be absorbed within the broader organization or influence pricing and contracting elsewhere.

The balance among those responses determines how much of the original purchaser effect becomes a broader economic effect.

The larger system is shaped by more than commercial purchaser behavior

Scale also introduces the interaction between private purchasing decisions and the broader payer environment.

Health care providers operate across commercial and public payer relationships that follow different payment structures and economic constraints. Changes created by commercial purchasers therefore occur alongside Medicare, Medicaid and other public payment arrangements, as well as the economics of other commercial services.

That creates an ongoing tension.

Even substantial optimization within one commercially financed service category may represent a relatively small change in the total economics of a health system. The effect becomes more consequential when it influences how resources are deployed, how capacity develops, how organizations contract, or how revenue expectations evolve across the broader payer and service-line mix.

The system can therefore absorb a meaningful amount of local optimization while preserving much of its underlying structure.

Scale does not necessarily mean coordination

Widespread adoption can also remain highly decentralized.

Individual employers, health plans and vendors may pursue similar strategies without acting as a coordinated purchasing block. Their aggregate volume may become substantial while remaining fragmented across networks, contracts and local markets.

The economic significance of that activity depends heavily on where it occurs. Concentrated purchasing activity in one market may change counterparty behavior materially. Similar activity dispersed across many markets may have a much smaller structural effect.

This creates an important distinction between the scale of adoption and the scale of market influence.

A strategy can become common without producing a common market response.

System effects emerge from the interaction with the existing structure

The eventual equilibrium depends on how the intervention interacts with the system that surrounds it.

  • The purchaser effect can become durable cost removal when lower-cost delivery reduces resources.

  • Reallocation results when resources migrate across sites, services or payer relationships.

  • Economic redistribution occurs when prices or payment relationships adjust and benefits shift among participants.

These outcomes can coexist, and the mix can differ substantially by market. Therefore, the economic consequences of scaled site-of-care optimization cannot be inferred simply by multiplying an individual purchaser result across a larger population.

Evidentiary ceiling

Scaled site-of-care optimization can change incentives and redirect meaningful amounts of spending. The broader effect depends on how those changes interact with other service lines, provider economics, local market structure, and the combined public and private payer environment.

The system-level result depends on what happens to resources, revenue and pricing after local purchaser actions become large enough to interact with those broader forces.
