Understanding Healthcare Delivery Models in the US
The United States healthcare system is a complex tapestry of public and private entities, each contributing to how medical services are delivered. Understanding the various healthcare delivery models is crucial for navigating this system, especially in the context of competitive exams like the USMLE. These models dictate how care is financed, organized, and provided to patients.
Key Healthcare Delivery Models
Several models shape healthcare delivery in the US. These often overlap and can be categorized by their primary focus, such as cost control, patient access, or quality of care.
| Feature | HMO (Health Maintenance Organization) | PPO (Preferred Provider Organization) |
|---|---|---|
| Primary Care Physician (PCP) Gatekeeper | Required | Not Required |
| Referrals to Specialists | Required from PCP | Not Required (can go directly to specialists) |
| Out-of-Network Coverage | Generally not covered (except emergencies) | Covered, but at a higher cost |
| Cost | Typically lower premiums and out-of-pocket costs | Typically higher premiums and out-of-pocket costs |
Public vs. Private Models
The US healthcare system is a hybrid, with significant roles played by both public and private sectors. Understanding these distinctions is vital for grasping the nuances of healthcare delivery.

Visualizing the flow of patient care within different delivery models can be complex. For instance, a Fee-for-Service model might show a linear progression of services, while a PCMH model would depict a more interconnected network of care coordination.
