Business Development

6B works with NHS Trusts and health tech innovators to build scalable, robust integrations with System C platforms, including CareFlow EPR, CarePlus, and Liquidlogic. Whether your solution supports clinical documentation, patient engagement, or operational automation, we provide end-to-end support across planning, development, testing, and deployment.

With a strong track record in NHS-facing system integration, 6B ensures your solution fits seamlessly into System C environments – reducing complexity and accelerating digital transformation.

Understanding System C and CareFlow EPR

System C is a leading provider of electronic patient record (EPR) and patient administration system (PAS) technology for the NHS. Their flagship platform, CareFlow EPR, combines powerful clinical and administrative functionality into a single, unified system. CareFlow is designed to help healthcare providers streamline care delivery, improve outcomes, and reduce administrative overhead.

CareFlow’s PAS is one of the most modern and NHS-aligned systems available, supporting a wide range of hospital operations from patient registration and outpatient self-check-in to clinic scheduling, bed management, and clinical coding. It is live in over 25 NHS Acute Trusts, serving both specialist and large teaching hospitals across the UK.

System C’s modular architecture also enables integration with a wide array of third-party solutions, creating opportunities for advanced clinical collaboration and patient-focused innovation.

Our System C Integration Process

At 6B, we take a structured and collaborative approach to System C integration, working closely with your technical and clinical teams to define integration requirements and map them to CareFlow’s APIs and data interfaces.

We design secure, real-time integration architectures using HL7 messaging and System C’s Open API framework. Our solutions support both transactional and bulk data exchange and are capable of integrating with cloud-hosted or HSCN-based environments, depending on your hosting model. Integration is secured through client certificate authentication and aligned to NHS and System C access protocols.

We also implement portal-style single sign-on (SSO) and contextual “click-through” integrations that maintain patient and user context between your solution and CareFlow. This allows clinicians to move fluidly between systems, access relevant data instantly, and maintain clinical focus. For specific workflows, we can embed System C interfaces directly within your application or enable your application to be launched from within the CareFlow interface – with full user and patient continuity.

Following rigorous integration testing, we support go-live deployment and ongoing monitoring to ensure long-term performance and compliance.

Benefits of System C Integration

Integrating with System C platforms enables your solution to deliver greater value to NHS customers by embedding into their clinical and operational workflows. Real-time data access improves decision-making, reduces duplication, and supports safer, more efficient care. SSO and contextual integration streamline the user experience, enabling clinicians to focus on patients instead of navigating disconnected systems.

For healthcare organisations, System C integration reduces administrative burden and improves interoperability with existing systems. It helps Trusts align with national digital strategies, such as NHS England’s Open API policy and the shift toward more integrated care.

For digital health vendors, integrating with System C makes your product easier to adopt and more valuable in NHS settings – accelerating time to deployment and return on investment.
