Nexus is the single pane of glass where every Clarion module — clinical documentation, AI detection, revenue cycle, scheduling, pharmacy, imaging — converges into one context-aware workspace built for the way clinicians actually work.
Epic Hyperspace was built as a thick-client application running on Citrix virtual desktops — an architecture that predates smartphones, cloud computing, and modern web standards. Hyperdrive, its browser-based successor, is a technical migration, not a rethinking. The workflows, the click depth, the information density — all remain fundamentally unchanged. Clinicians spend more time navigating their EHR than examining their patients.
Every capability below is natively integrated — not bolted on. Nexus does not open separate windows, launch external applications, or require context switching. The workspace adapts to the clinician's role, the patient's condition, and the task at hand.
When an emergency physician opens Nexus, the workspace surfaces ED-specific views — triage board, trauma protocols, rapid order sets, and the Sentinel AI alert feed. When a cardiologist opens the same system, the canvas reconfigures to show echocardiography results, catheterization schedules, hemodynamic trends, and Cardiac engine risk scores. No configuration required. No role-switching. Nexus reads the clinician's identity, specialty, department, and active patient context, and assembles the workspace in real time.
Nexus listens. When a physician speaks with a patient, the ambient documentation engine captures the encounter, identifies clinical elements — history, assessment, plan, medications discussed, orders implied — and generates a structured clinical note before the physician leaves the room. The note maps to specialty-appropriate templates, assigns ICD-10 codes with 96.8% accuracy, and surfaces relevant clinical decision support. Physicians review and sign; they do not type. This is not transcription. This is clinical reasoning captured in real time.
Nexus is the delivery vehicle for every Sentinel engine. Sepsis risk scores do not live in a separate dashboard — they appear as contextual indicators on the patient's chart header. PE probability calculations surface when D-dimer results arrive. Cardiac arrhythmia alerts display alongside the telemetry strip. Drug interaction warnings from Pharma appear at the moment of order entry, not after. Nexus treats AI signals as first-class clinical data, integrated at the point of decision — not buried in a separate application that clinicians must remember to check.
Nexus merges computerized physician order entry, electronic prescribing, and laboratory/imaging ordering into a single, predictive interface. As the clinician types, Nexus suggests evidence-based order sets informed by the patient's active diagnoses, current medications, allergies, renal function, and formulary coverage. Drug-drug, drug-allergy, drug-lab, and drug-food interactions are checked in real time by the Pharma engine — with severity-tiered alerts that eliminate the fatigue of non-actionable warnings. Prior authorization status from Arbiter RCM is displayed at the point of order, not discovered days later when a claim is denied.
Nexus runs natively in any modern browser — Chrome, Edge, Safari, Firefox — on any device, any operating system, without Citrix, without VDI, without thick-client installation. A physician can open a full-featured clinical workspace on a hospital workstation, a personal laptop at home, a tablet on rounds, or a shared COW at the nursing station. Session state persists across devices: a chart opened on the desktop is waiting on the tablet. Offline capability ensures critical patient data remains accessible during network interruptions — a feature conspicuously absent from legacy thick-client architectures.
Revenue integrity begins at the moment of care, not in a billing office three days later. Nexus runs Arbiter's autonomous coding engine in real time as the encounter unfolds. When the ambient documentation engine captures a diagnosis, Arbiter simultaneously maps it to the optimal code, checks for documentation completeness, flags potential denial risk, and verifies insurance eligibility. By the time the physician signs the note, the claim is already coded, scrubbed, and queued — with a predicted clean-claim probability displayed as a confidence indicator. Clinicians never see the billing logic; they simply practice medicine while the system captures every dollar they have earned.
Communication failures cause 70% of sentinel events. Nexus embeds secure, HIPAA-compliant messaging directly in the patient chart — not in a separate pager system, not in a consumer messaging app. Structured I-SBAR handoff templates guide shift transitions. Escalation pathways route critical alerts to the right provider with read-receipt confirmation. Every message is permanently linked to the patient record, creating a complete audit trail of clinical communication that legacy systems scatter across pagers, phone calls, and sticky notes.
Nexus is built on FHIR R4 from the ground up — not retrofitted onto a 40-year-old MUMPS database with a FHIR facade. Every clinical data element is natively FHIR-addressable. Third-party applications connect through SMART on FHIR without custom development. Carequality and CommonWell participation enables data exchange with any health system regardless of their EHR vendor. Patient data belongs to patients and their care teams — not to a vendor's proprietary ecosystem. This is the anti-Hyperspace philosophy: open by design, interoperable by default, portable by right.
Nexus is not a user interface bolted onto a 1990s database. It is a purpose-built clinical platform where every layer was designed for the era of AI-assisted medicine, cloud-native deployment, and open interoperability.
Three health systems. Three deployment models. Measurable outcomes within 90 days of go-live.
A 14-hospital academic medical center with 4,200 beds and 38,000 employees replaced their Epic Hyperspace environment with Clarion Nexus in a phased 11-month deployment. Physicians reported an average of 47 minutes per day saved on documentation. The health system eliminated its Citrix infrastructure, reducing annual IT operating cost by $8.2 million. Sentinel AI detection engines identified 1,847 clinical deterioration events in the first six months that would have been missed by rule-based BPAs.
A six-hospital community health system in the rural Midwest — previously running a patchwork of paper charts and legacy Meditech — deployed Nexus as its first enterprise EHR. The ambient documentation engine was the decisive factor: physicians who had resisted EHR adoption for a decade accepted Nexus because it did not require them to type. First-pass clean claim rate improved from 71% to 94% within 90 days as Arbiter RCM automated coding that had previously been done manually by three full-time coders per hospital.
I spent eleven years of my career fighting Epic. Fighting the clicks, fighting the pajama time, fighting the documentation burden that was destroying my relationship with medicine. Nexus gave me back the thing I became a doctor for — the ability to look at my patient, talk to my patient, and trust that the system behind me is capturing what matters. I will never go back.
We eliminated $8.2 million in annual Citrix licensing and VDI infrastructure costs in the first year. Our physicians are documenting 47 minutes less per day. Our clean claim rate went from 82% to 96%. And for the first time in my twenty years as a CIO, I have physicians calling to thank me for the technology we deployed. That has never happened before.
