Evidence-based questions (supplier transparency)

Our Healthcare RFI and RFP templates are designed to obtain supplier transparency. For each relevant topic (e.g., security controls, governance, clinical safety expectations), suppliers must answer and attach supporting artefacts (policies, certifications, test summaries, data flow details, SLAs). Netify does not certify these claims; buyers use the evidence to complete due diligence. Supplier responses are supplier attestations and should be supported by documentation.

● Executive Summary

Legacy WAN architectures cannot support healthcare's demands for clinical application performance, multi-site connectivity and regulatory compliance, however SD-WAN and SASE solutions provide the answer through application-aware routing, centralised management and integrated security for NHS Data Security and Protection Toolkit (DSPT), UK GDPR and Caldicott Principle compliance.

● Impact on Patient Care

Healthcare organisations depend on network connectivity for every patient interaction, clinical decision and administrative process. When networks fail or perform poorly, clinicians cannot access patient records, diagnostic images experience delays, telehealth consultations freeze mid-session and critical alerts from connected medical devices fail to reach the appropriate staff - resulting in delayed treatment decisions, compromised patient safety and potential regulatory breaches.

× CONNECTION LOST

● Operational Strain

Whilst traditional healthcare network architectures can often struggle with operational demands (especially when considering the complexity of modern digital health workflows), at the same time connectivity itself, such as MPLS circuits, are expensive to deploy across geographically dispersed sites and inflexible when services relocate or new facilities open - something that happens frequently as healthcare providers adapt to changing population needs and commissioning arrangements. On top of this, backhauling all traffic through central data centres can introduce latency that degrades real-time applications (such as Picture Archiving and Communication Systems and telehealth platforms), leading to single points of failure, as well as the needs for guest WiFi, medical IoT devices and remote working staff all competing for bandwidth, which can squeeze capacity for clinically critical systems during peak periods.

HIGH TRAFFIC VOLUMES

● SD-WAN & SASE Solution

However, with SD-WAN and SASE architectures, healthcare organisations can address these challenges through the likes of application-aware traffic management, supporting multiple connectivity types, which is also beneficial for resilience, and providing centrally managed security that scales across distributed sites and minimising the need for on-site expertise. For healthcare providers, SD-WAN and SASE can offer solutions for the majority of pain-points that traditional WAN causes, alongside supporting the sector's regulatory requirements.

SECURE FABRIC

How does the healthcare operating environment impact connectivity requirements?

Although there are often many common themes and demands across the healthcare sector, it's easy to forget that not all healthcare organisations' needs are the same - operating across different site types, each with distinct connectivity requirements and tolerance for failure. Understanding these operational differences is essential when evaluating SD-WAN and SASE solutions, as the consequences of network failure vary dramatically depending on location type and the clinical systems that depend on connectivity.

● GP Surgeries & Primary Care

GP surgeries and primary care sites depend on continuous connectivity for electronic patient records, e-prescribing and referral systems. Even though some clinical systems offer limited offline functionality for appointment notes, these capabilities have significant restrictions - clinicians cannot access patient history, medication records or test results without live connectivity.

Extended network outages can force practices to revert to paper-based processes, creating patient safety risks from incomplete information and administrative backlogs that take days to clear.

Cloud EPR GP Surgery Live Records

● Acute Hospitals

As to be expected with larger facilities, acute hospitals introduce considerably more complex performance requirements - electronic patient records remain critical, however these sites now run the likes of Picture Archiving and Communication Systems (PACS) requiring rapid transfer of diagnostic images (often several hundred megabytes per study), real-time patient monitoring systems transmitting continuous vital signs, and laboratory information systems coordinating thousands of test results daily.

And whilst the effect of some issues can sometimes be absorbed by hospitals for the betterment of patient experience (such as slightly delayed non-urgent results), other effects can be directly harmful. For example, slow PACS performance means radiologists cannot review diagnostic images promptly, potentially delaying time-critical diagnoses. Furthermore, more direct effects on hospitals can come from delayed critical alerts from patient monitoring systems failing to reach clinical staff in time - either compromising patient safety or requiring manual workarounds that consume nursing time.

● Community Healthcare

Unlike both primary care sites and acute hospitals, community healthcare facilities represent a dispersed operational model. District nursing teams, community mental health services and rehabilitation centres often operate from smaller sites with minimal IT support. Within these, network reliability is essential for mobile clinicians accessing records during home visits (often via 4G/5G), secure messaging between care teams and video consultations with patients who cannot travel.

When community site networks fail, the impact can cascade across patient pathways - discharge planning stalls, medication reviews are delayed and vulnerable patients miss essential monitoring.

Technical Performance Standards

Healthcare SD-WAN deployments must satisfy specific performance thresholds to support clinical workflows without compromising patient care delivery.

● High-Bandwidth Imaging

Standard 3D mammography files are often multiple gigabytes per examination, creating significant bandwidth demands for radiology departments. Legacy connections require far longer to transfer a single high resolution imaging file, introducing delays in diagnostic workflows where radiologists must compare current studies against previous examinations.

The Impact of Latency on Diagnostics:

  • Diagnostic Accuracy: UK NHS trusts report that radiologists examining CT scans with thousands of individual slices require instant image progression to maintain diagnostic accuracy, with any buffering or lag introducing eye strain and potential diagnostic errors during multi-hour reading sessions.
  • Burst Traffic Handling: Radiology departments with multiple consultants simultaneously accessing PACS during morning reporting rounds generate burst traffic reaching 2-3Gbps, requiring bandwidth aggregation across multiple circuits to prevent image rendering queues.

SD-WAN broadband links reduce this transfer time to a fraction of the time, enabling radiologists to access imaging studies without clinical workflow interruption during on-call emergency trauma assessments.

PACS TRAFFIC BURST 08:00 09:00 (Rounds) 10:00 3 Gbps

● Real-Time Clinical Comms

Real-time video consultations and VoIP communications require strict latency and jitter tolerances to maintain clinical communication quality. Industry standards state that latency should remain under 150ms and jitter under 30ms to prevent issues with voice or video buffering.

Forward Error Correction (FEC):

The Forward Error Correction (FEC) capabilities of SD-WAN enables the reconstruction of lost packets in real-time without retransmission delays, maintaining audio/video quality even when packet loss reaches 1-2% during peak usage periods.

  • Patient Experience: UK primary care networks report that FEC capabilities typically eliminated the previous consultation interruptions that forced patients to repeat symptoms descriptions, that had otherwise resulted in extending appointment durations by up to 3-5 minutes each.
  • Clinical Safety: Cardiology departments conducting remote patient monitoring via video consultations require clear audio to detect respiratory distress indicators including speaking difficulty and breathing patterns.
PACKET RECONSTRUCTION (FEC) LOST (1-2%) RECONSTRUCTED

● EHR Latency & Efficiency

Healthcare IT departments report that legacy connections with 100-200ms latency create visible delays in screen transitions, forcing clinicians to pause between clicks to ensure previous actions completed. This accumulated lag reduces patient throughput and extends clinician working hours.

  • Operational Impact: UK A&E departments reporting that Epic screen lag contributed to 10-15% increases in patient documentation completion times during winter pressures when departments operate above capacity.
  • The SD-WAN Fix: With SD-WAN deployments, healthcare organisations were able to achieve consistent sub-50ms round-trip latency through path selection optimisation, ensuring instantaneous screen updates that match on-premises performance characteristics.

UK private hospital groups report that eliminating VDI lag improved clinician satisfaction scores whilst reducing the time required to complete patient documentation.

Strategic Overview & Technical Deep Dive

Select a topic to explore regulations (DUAA 2025), vendor scenarios, and procurement strategies.

Compliance & Security 2026: The Data (Use and Access) Act

Healthcare SD-WAN deployments must satisfy evolving UK and international regulatory requirements whilst maintaining patient data protection during clinical workflow optimisation.

Data (Use and Access) Act 2025 (DUAA)

The Data (Use and Access) Act 2025 (DUAA) introduces mandatory data auditing and access control requirements for healthcare organisations processing patient information. SD-WAN platforms support these compliance obligations through centralised logging and policy enforcement, enabling healthcare organisations to demonstrate which clinician accessed which patient record, when access occurred and which clinical applications processed protected health information.

AI-Assisted Diagnostics & Human-in-the-Loop

UK healthcare providers integrating AI-assisted diagnostic tools into radiology and triage workflows face specific human oversight requirements under the Data (Use and Access) Act 2025 (DUAA).

Network-induced delays displaying AI-generated diagnostic overlays on high-resolution CT scans create screen lag that impedes human intervention (required under DUAA Article 22A), potentially creating bottlenecks in critical care pathways. SD-WAN architectures resolve this by supporting AI-assisted radiology workflows with sub-50ms latency for simultaneous display of original DICOM imaging studies alongside AI-generated annotations.

Encryption & NHS DSPT

NHS Data Security and Protection Toolkit (DSPT) and HIPAA regulations mandate that encryption keys for patient data transmissions remain under healthcare organisational control rather than third-party transport providers. Healthcare SD-WAN deployments implement customer-managed encryption (CME) where healthcare organisations generate, store and rotate cryptographic keys independently of connectivity providers.

DUAA 2025 Article 22A Human-in-the-Loop <50ms Latency

Vendor Application Scenarios

Healthcare organisations should select SD-WAN vendors based on specific clinical use cases rather than generic feature comparisons.

Use Case A: Home Radiologists (VMware VeloCloud)

VMware VeloCloud addresses the technical challenges of enabling radiologists to read high-resolution imaging studies from home broadband connections during on-call emergency trauma assessments.

Dynamic Multi-Path Optimisation (DMPO) continuously monitors available paths and steers individual packets across optimal routes based on real-time latency, jitter and loss measurements. UK radiology groups report that DMPO enables consultants to access PACS systems from residential internet connections without the rendering delays that plagued previous home-working implementations.

Use Case B: Clinic Consolidation (Fortinet)

Fortinet Secure SD-WAN addresses space and budget constraints in smaller GP surgery and community clinic facilities through ASIC-accelerated security processing that combines routing and firewall functions within single appliances. UK GP surgery networks deploying Fortinet report that consolidating previously separate routers and firewalls freed physical space in small server rooms whilst reducing appliance purchase costs by 30-40%.

Use Case C: Ambulances (Peplink)

Peplink SpeedFusion addresses the connectivity challenges of mobile healthcare delivery through packet bonding across multiple cellular carriers simultaneously. Ambulances equipped with dual-SIM configurations leverage SpeedFusion to aggregate bandwidth and eliminate dead zones, ensuring paramedics can transmit real-time ECG telemetry and video feeds to emergency department physicians during patient transport.

Frequently Asked Questions

Common questions regarding healthcare network architecture, compliance, and clinical performance.

How does SD-WAN optimise DICOM/PACS image transfers?
SD-WAN optimises DICOM (Digital Imaging and Communications in Medicine) and PACS transfers through bandwidth aggregation and WAN optimisation techniques including deduplication and caching. Bandwidth aggregation combines multiple internet connections into unified logical links, enabling radiology departments to sustain burst transfers during peak imaging periods without saturating individual circuits. UK hospital groups report that caching reduced cross-site image transfer times by 60-70% for follow-up examinations.
Can SD-WAN replace private MPLS circuits for patient records?
Yes, SD-WAN can replace private MPLS circuits through packet duplication over dual internet links, matching the reliability characteristics of dedicated private lines. Packet duplication transmits identical copies of patient record updates across multiple independent paths simultaneously, with receiving endpoints selecting the first-arriving packet. UK private hospitals report that dual-broadband configurations with packet duplication achieved 99.98-99.99% uptime, comparable to MPLS private circuits whilst reducing costs by 50-65%.
What are the requirements for cloud-hosted Epic EHR?
Cloud-hosted Epic EHR deployments require under 50ms round-trip latency and high session persistence to prevent disconnects that force clinicians to re-authenticate. Epic's Hyperspace client maintains persistent TCP connections, with interruptions triggering automatic logouts that discard unsaved nursing notes. UK healthcare organisations deploying Epic in AWS or Azure report that SD-WAN path selection ensuring consistent sub-50ms latency eliminated session timeout issues.
How does SD-WAN support the Data (Use and Access) Act 2025?
The Data (Use and Access) Act 2025 (DUAA) introduces mandatory data auditing and access control requirements. SD-WAN platforms support this through centralised logging and policy enforcement, demonstrating which clinician accessed which record. Furthermore, for AI-assisted diagnostics, SD-WAN ensures the sub-50ms latency required for "human-in-the-loop" intervention as mandated by DUAA Article 22A.
How are mobile ambulances and community clinics supported?
Mobile healthcare delivery is supported through packet bonding across multiple cellular carriers. For example, ambulances leverage Peplink SpeedFusion to aggregate bandwidth from multiple SIMs, eliminating dead zones and ensuring paramedics can transmit real-time ECG telemetry and video feeds to emergency physicians.
