Academic Medical Centers Broke Primary Care

Primary Care Access, Academic Consolidation, and Why Patients Keep Escalating Care

Introduction

When patients describe problems with the healthcare system, they rarely talk about organizational charts, payment models, or network design. They talk about time.

Time to get an appointment.

Time waiting for a callback.

Time until a referral is approved.

Time until someone actually sees them.

Access failure is experienced temporally. That matters, because it means access is not an abstract concept. It is a measurable outcome of how systems allocate physician time.

Over the past decade, primary care access has deteriorated most sharply in large metropolitan markets dominated by academic medical centers and vertically integrated health systems. This deterioration is often attributed to physician shortages or increasing patient complexity. Those explanations do not account for the observed patterns. What changed most during this period was ownership and control of primary care.

This analysis examines how that structural change aligns with access outcomes, downstream specialty delays, and escalation of care.

What Primary Care Historically Did

Primary care historically functioned as an access buffer. It absorbed uncertainty early and prevented unnecessary escalation to higher levels of care. That role depended on two structural conditions:

1. Practice-level control of scheduling and visit capacity

2. Multiple independent entry points competing on access

Independent practices adjusted schedules, added visits, and responded to demand variability because access was central to their survival. Once primary care was consolidated, that elasticity was lost.

What Consolidation Changed Operationally

When academic medical centers and large systems acquired primary care practices, the clinical content of visits did not fundamentally change. What changed was control of access.

Across markets, consolidation produced a similar operational profile:

• Primary care physicians became employees

• Scheduling was centralized

• Visit templates and panel sizes were standardized

• Referral pathways were internalized

• New-patient access was triaged administratively

These changes shifted control of physician time from clinicians to organizations. Access became a managed resource, not a responsive one.

Primary Care Wait Times as a Direct Measure of Access

Wait time is the most direct, patient-relevant access metric. It reflects the balance between demand and usable capacity.

Figure 1A. Primary Care Physician Wait Times vs National Average

What this figure shows

Average family medicine wait times across major U.S. markets compared with the national average. Markets dominated by academic medical centers consistently exhibit longer waits. Markets with fragmented, independent primary care access cluster near or below the national norm.

This pattern appears across regions and payer mixes.

Defining Structure: The Primary Care Ownership / Control Index (PCOCI)

To move beyond descriptive comparisons, access must be analyzed in relation to who controls it. For that purpose, this analysis uses the Primary Care Ownership / Control Index (PCOCI).

PCOCI is a structural index, not a performance metric. It does not measure quality, utilization, or outcomes. It measures control over primary care access.

The index exists to answer one question:

Who determines how primary care time is allocated in this market?

How PCOCI Is Constructed

PCOCI is based on four observable features of primary care organization. Each reflects a distinct mechanism by which control over access shifts from clinicians to systems.

1. Primary care physician employment

Markets score higher when a large share of primary care physicians are employed by hospital systems or academic medical centers rather than operating independent practices. Employment matters because it transfers control of schedules, visit length, and panel size from physicians to organizations.

2. Dominance of one or two systems

Markets score higher when primary care access is concentrated within one or two dominant systems. In these environments, patients have fewer independent entry points and competition no longer disciplines access.

3. Referral containment

Markets score higher when primary care referrals are routinely routed to system-owned specialists, facilities, and outpatient departments. This reflects vertical integration and constrains where follow-up care can occur.

4. Centralized scheduling and triage

Markets score higher when scheduling is centralized and new patients are routed through portals or call centers, often defaulting to non-physician clinicians before accessing a physician.

Each component is scored conservatively. The index is ordinal, not continuous. Its purpose is comparability across markets, not precision at the margin.

Why PCOCI Works as an Access Framework

PCOCI works because access is not determined by stated mission, quality ratings, or headcount. It is determined by who controls physician time.

In markets where primary care remains independent and fragmented, practices compete on availability and responsiveness. In markets where primary care is consolidated and centrally managed, access becomes a system-level resource that is rationed.

PCOCI captures that distinction directly.

Measuring Access Abnormality, Not Just Delay

National primary care access is already strained. Matching the national average does not indicate good performance. A more informative approach is to examine deviation from the national mean.

Figure 1C. Deviation from National Primary Care Wait Time

What this figure tests

Whether markets with higher primary care control operate outside normal access behavior.

How it is constructed

Each market’s average wait time is expressed as days above or below the national average. Zero represents expected access under current national conditions.

Why markets are ordered by PCOCI

Ordering by PCOCI tests whether access abnormality increases monotonically with control.

What it shows

Deviation from normal increases systematically as primary care becomes more tightly controlled. Markets with low PCOCI cluster near or below zero.

This isolates structural distortion rather than scale effects.

Downstream Effects: Specialty Access

Primary care is the gateway to most specialty services. When access is constrained upstream, downstream bottlenecks are expected.

Figures 2A–2C. Gastroenterology, Dermatology, and OB/GYN Wait Times

Across referral-dependent specialties, the same markets exhibit prolonged waits. These specialties are not “owned” by primary care, but their access depends on referral flow and internal capacity management.

This indicates system-wide effects, not specialty-specific shortages.

Cumulative Delay at the Patient Level

Patients experience delays sequentially.

Figure 3. Total Access Delay Across Routine Care

This figure aggregates deviation from national norms across primary care and three downstream specialties. In highly consolidated academic markets, cumulative delay reaches months relative to national expectations.

Workforce Is Not the Primary Driver

If access failure were primarily due to physician shortage, higher supply would correlate with better access.

Figure 4. Primary Care Supply vs Total Access Delay

Some of the worst-performing markets have among the highest primary care physician supply. Some of the best-performing markets have less. Supply alone does not explain access outcomes.

Independent Entry Points Preserve Access

Ownership fragmentation is a stronger explanatory variable.

Figure 5. Independent Primary Care Entry Points vs Total Access Delay

Markets with more independent primary care practices per capita consistently demonstrate better access, even with fewer physicians overall.

Escalation of Care

When primary care access is constrained, patients escalate.

Figure 7A. Primary Care Delay and Emergency Department Escalation

Emergency department visits for ambulatory care-sensitive conditions increase as primary care access deteriorates.

Figure 7B. Primary Care Delay and Urgent Care Growth

Urgent care growth tracks closely with primary care access failure, functioning as a pressure-release mechanism.

What This Analysis Is and Is Not Claiming

This analysis does not assign intent or question clinical excellence. It does not argue against coordination of care.

It demonstrates that ownership and control of primary care alter access behavior, and that the resulting outcomes are consistent, measurable, and predictable.

Implications

As long as primary care is centrally managed as an intake function, access will remain constrained regardless of physician supply. Expanding urgent care or increasing nominal access points will not substitute for timely physician access.

Conclusion

Primary care access deteriorated most severely where it became most controlled. This is not a failure of clinicians. It is a consequence of how primary care was reorganized within large academic and integrated systems.

The access outcomes that followed are predictable, measurable, and consistent.
