Hub-and-Spoke Model for In-House PCR in Primary Care Networks

Molecular diagnostics are becoming more and more commonplace in healthcare delivery, and Primary Care Practices (PCPs) are especially familiar with the increasing utilization of Polymerase Chain Reaction (PCR). 

As the use of PCR scales, some practices have begun to recognize the difficulties associated with using third-party reference labs and have opted to adopt PCR as an in-house service instead. This shift is enabling practices to obtain better control over turnaround times, create a predictable cost-per-test, and reduce their dependence on external services.

However, implementing on-site PCR also means setting up a full-fledged PCR lab, which can be daunting at first. While tackling those challenges and establishing a lab can be beneficial even for standalone practices, the real benefits become most apparent in multi-location primary care networks. In these settings, a “hub-and-spoke” model is the best approach to establishing your in-house PCR infrastructure—it offers a high level of operational efficiency, streamlined quality management, and cost advantages through economies of scale.

Understanding the Hub-and-Spoke Framework

The hub-and-spoke model, simply put, uses a primary testing facility (the hub) at one location that services several primary care locations (the spokes). The hub site can be integrated into one of your established primary care practices, or it can be a standalone lab space occupying a small footprint.

Spoke clinics are only responsible for collecting specimens at the point of care before handing them off to a courier service which brings samples back to the central hub. Upon receipt, the hub handles processing, molecular analysis, and relaying results electronically.

The central laboratory requires its own dedicated space, specialized PCR equipment, and qualified lab personnel who focus exclusively on specimen processing and analysis. To ensure regulatory compliance, personnel need to maintain CLIA certification, adhere to ISO standards, etc, and also implement rigorous quality assurance protocols to make sure that results are consistent and reliable.

Key Advantages of the Hub-and-Spoke Approach

1. Enhanced Quality Assurance

Centralizing PCR testing operations allows you to maintain superior quality control over your PCR workflow by having all your samples processed in a single, controlled environment overseen by dedicated laboratory staff. This not only means better adherence to regulatory standards, but also consistent testing standards and dependable result turnaround times so providers across your network can confidently rely on your PCR for their clinical decision-making.

2. Simplified Integration for Individual Practices

While there is a heavy lift associated with setting up your first lab, there is a low barrier to entry for each individual practice location, where sample collection and courier pickup will remain mostly unchanged. A streamlined approach like this supports easier adoption of PCR testing capabilities across your network.

3. Consolidated Technical Expertise

The hub and spoke model concentrates specialized expertise at the hub, which means you won’t have to distribute technical resources across multiple sites. Dedicated laboratory professionals use their domain expertise to manage equipment operation, provide technical support to spoke sites when needed, and maintain highly-specific protocols. This allows your individual practices to focus on patient care instead of new PCR requirements.

4. Maximized Resource Efficiency

A centralized model means better resource management—the hub maintains its own lab-specific reagents and consumables in one place, as well as managing and distributing spoke-related collection inventory from a single location, allowing you to reduce redundancy and waste. Having all testing performed at one location also sees economies of scale at work due to higher-volume batch processing, leading to better cost efficiency per test.

5. Consistent Network-Wide Protocols

As opposed to a lab at each site, centralized testing can eliminate the complexity of maintaining different protocols at each location—specimen collection, delivery, interpretation, and data reporting can be made uniform across all practices. This type of uniformity simplifies staff training and allows providers to transition seamlessly from one practice to another when needed.

6. Effortless Network Expansion

Growing networks need the ability to “plug-and-play” new practice locations—the hub-and-spoke structure makes this easier to do. Rather than establishing a lab at each new site, practices can immediately begin using the central hub's testing capabilities, which can accelerate the integration of new locations.

7. Future-Ready Scalability

Plug-and-play capability means one of the hub-and-spoke model's greatest strengths is its inherent scalability. The central hub can be designed to accommodate increasing testing volumes as new practices join the network, eliminating the need for a proportional investment at each location. If your primary care network is planning strategic growth, the flexibility of easy scaling is critical.

Strategic Impact

For multi-location primary care networks, the hub-and-spoke implementation model is a strategic approach to adopting in-house PCR. This framework can centralize essential laboratory operations, ensure consistent quality, unify protocols, reduce waste, and allow for future expansion. Primary care practice networks adopting in-house PCR should consider this model to prepare themselves for the evolving world of molecular diagnostics.
