TL;DR: The telehealth platforms most providers rushed to launch in 2020-2021 were built to solve a 2021 problem: get a video call in front of a patient, fast. By 2026, telehealth accounts for 25-30% of US medical visits and patients expect retail-grade experiences, while providers need ambient documentation, bidirectional EHR write-back, and continuous remote patient monitoring data — none of which the typical pandemic-era MVP architecture was designed to support. Most of those platforms either skipped EHR integration entirely or built read-only FHIR connectivity, and both choices now require rearchitecting the data layer, not just adding features on top.
Telehealth stopped being an emergency stopgap
In 2020 and 2021, the mandate for most healthcare organizations was simple: get some video visit capability live in weeks, not months. Architecture decisions were made under that pressure — vendor video SDKs bolted onto existing patient portals, minimal EHR connectivity (if any), and scaling plans that assumed a temporary surge rather than a permanent shift in how care gets delivered.
That assumption didn't hold. By the end of 2026, telehealth is projected to account for 25-30% of all US medical visits, spanning primary care, behavioral health, chronic disease management, and post-operative follow-up. It's no longer an alternative channel — for a meaningful share of patients, it's the default front door to care. Platforms built for a temporary surge are now permanent infrastructure, and the gap between what they were designed to do and what they're being asked to do has become the primary constraint on what healthcare organizations can build next.
What the pandemic-era MVP typically got wrong
Most telehealth platforms built in that 2020-2021 window share a common set of architectural shortcuts, all of which made sense under the original time pressure and all of which now create real friction:
EHR integration was skipped or built read-only. Getting a video call working didn't require deep EHR connectivity, so most MVPs either had none or built a minimal, read-only FHIR pull to display basic patient context during a visit. That was adequate for "doctor looks at chart, talks to patient over video." It is not adequate for what 2026 clinical workflows expect: ambient AI documentation that needs to write structured notes back into the EHR in real time, AI-assisted triage that needs full clinical history (not a summary snapshot) to make a reasonable recommendation, and remote patient monitoring that needs continuous, bidirectional device data flowing into the same record the video visit touches. Read-only connectivity simply can't support write-back, and bolting write capability onto a system that was never designed for it usually means rearchitecting the data layer rather than adding an endpoint.
Everything scaled together, or didn't scale independently. A monolithic pandemic-era build typically scaled the whole application when any single part of it — video infrastructure, notification delivery, claims processing — hit a traffic spike. That's expensive and fragile. A platform that separates these concerns can scale high-volume video traffic independently from claims processing or notification delivery, which matters enormously once volume is a permanent baseline rather than an occasional surge.
Vendor lock-in on video and EHR was baked in early, under time pressure. Many 2020-era builds hardwired a single video SDK and a single EHR integration because there wasn't time to build an abstraction layer. That was a reasonable trade-off at the time. Three to five years later, as telehealth platforms expand into remote patient monitoring, chronic care management, home care, and behavioral health — each of which may need a different EHR relationship or a different real-time communication requirement — that hardwiring becomes the thing blocking expansion.
Security and compliance were built to the 2020 HIPAA baseline, not the current one. The HIPAA Security Rule update that's being enforced through 2026 adds meaningfully more specific requirements around remote access security, multi-factor authentication, encryption standards, and technology asset inventory. A platform built to 2020-era compliance assumptions is very likely carrying gaps against the current standard, particularly around access control granularity and audit logging depth.
What a 2026-grade telehealth architecture actually needs
Bidirectional, real-time EHR connectivity, not a read-only pull. This is the single highest-leverage rearchitecture most platforms need. Structured note write-back, orders, and real-time chart access during a visit require an integration layer built around FHIR and HL7 standards designed for two-way flow, not the lighter-weight read-only connections that were sufficient for a 2021 video visit.
A modular, independently scalable service layer. Video/streaming infrastructure, EHR integration, notification and messaging, claims and billing, and remote monitoring data ingestion should be separable services that can scale (and fail) independently. A traffic spike in video visits shouldn't be able to take down claims processing, and vice versa.
Vendor-agnostic integration patterns. Rather than hardwiring one video vendor or one EHR, a well-built abstraction layer lets the platform swap or add vendors as the organization's needs expand — critical once telehealth stretches into remote patient monitoring, home care, and behavioral health, each of which often comes with its own specialist vendor ecosystem.
Continuous, bidirectional device data pipelines for remote patient monitoring. As RPM becomes a standard part of chronic disease management, the platform needs to ingest continuous device data (glucose monitors, blood pressure cuffs, wearables) and make it available in real time to clinicians and AI triage tools — a fundamentally different data pattern than the request/response model most video-visit platforms were built around.
Compliance and security architecture matched to the current HIPAA Security Rule. This means granular access controls, comprehensive audit logging, multi-factor authentication enforced at the platform level (not just the EHR's), current encryption standards for data in transit and at rest, and — critically — a signed Business Associate Agreement with every vendor in the chain that touches PHI, including video platforms, messaging tools, and any RPM device vendor.
The build-vs-rebuild decision
Not every pandemic-era platform needs a full rebuild, and jumping straight to "replace everything" is usually the wrong instinct — it's expensive, disruptive to a system that's actively serving patients, and often unnecessary if the underlying data layer can be extended rather than replaced. A more practical sequence:
- Audit the current EHR integration first. If it's read-only, this is almost always the highest-priority rearchitecture, since so much of what 2026 clinical workflows need (ambient documentation, AI triage, RPM) depends on bidirectional data flow.
- Identify which services are currently coupled that shouldn't be. Video infrastructure and claims processing scaling together is a common and fixable coupling issue without a full platform rewrite — it's an extraction project, not a rebuild.
- Assess vendor lock-in against your actual expansion roadmap. If the organization plans to expand into RPM or behavioral health in the next 12-24 months, the cost of building an abstraction layer now is almost always lower than the cost of a forced migration later when a specific vendor can't support the new use case.
- Run a compliance gap assessment against the current HIPAA Security Rule, not the 2020 baseline the platform may have been built to. This is often the fastest-turnaround, highest-risk-reduction piece of the whole rearchitecture.
- Only consider a full platform rebuild if the audit reveals the data layer itself is fundamentally incompatible with bidirectional, real-time requirements — which does happen, particularly with platforms built entirely around a single vendor's closed video SDK with no real integration surface.
Comparison: pandemic-era MVP vs. 2026-grade platform
| Capability | Typical 2020-2021 MVP | What 2026 clinical workflows need |
|---|---|---|
| EHR connectivity | Read-only or none | Bidirectional read/write, real-time |
| Scaling model | Whole application scales together | Independently scalable services (video, claims, notifications, RPM) |
| Vendor relationships | Hardwired to one video SDK, one EHR | Abstraction layer supporting multiple vendors |
| Remote patient monitoring | Not supported or bolted on separately | Native continuous, bidirectional device data ingestion |
| Documentation | Manual, post-visit | Ambient AI documentation with structured write-back during the visit |
| Compliance baseline | 2020 HIPAA Security Rule assumptions | Current Security Rule: granular access control, MFA, updated encryption, full audit logging |
| Clinical AI readiness | Not designed for it | Real-time access to full clinical history for triage and decision support |
Why "just add AI features" doesn't work on the old architecture
A common pattern right now is a healthcare organization trying to bolt AI-driven features — ambient documentation, AI-assisted triage, automated clinical summarization — directly onto a pandemic-era platform without addressing the underlying data layer first. This almost always runs into the same wall: these features need real-time, structured, bidirectional access to clinical data, and a platform built around a read-only FHIR pull or a manual documentation workflow simply doesn't have anywhere for that data to flow. Ambient documentation, specifically, needs to write structured notes back into the EHR as the visit happens — not after, not as an export — which is a capability the original architecture was never asked to support.
This is worth calling out because it's a common and expensive mistake: teams scope an "AI feature" project without realizing the actual blocker isn't the AI model or the feature logic, it's the data plumbing underneath it. The rearchitecture work (bidirectional EHR integration, a proper event-driven data layer) is a prerequisite for the AI feature, not a parallel workstream — and skipping that reality tends to produce a demo that works in a controlled environment and falls apart against real EHR data and real clinical workflows.
Patient experience expectations have moved too
It's not just clinical workflows driving the need to rearchitect — patient expectations have shifted substantially since 2021. Patients booking a telehealth visit today are comparing the experience against retail-grade consumer apps: instant scheduling, clear wait-time visibility, seamless rescheduling, integrated messaging with the care team, and a mobile experience that doesn't feel like an afterthought bolted onto a desktop-first video tool. Platforms built in 2020-2021 under extreme time pressure often shipped a functional-but-rough experience that was acceptable when the alternative was no telehealth option at all. That's no longer the competitive bar. Organizations retaining patients on telehealth are increasingly the ones that treated the patient-facing experience as seriously as the clinical and compliance requirements — which again tends to require the same underlying architectural flexibility (independently scalable, vendor-agnostic services) rather than a purely cosmetic front-end refresh.
Where Syslabs fits in
We work with healthcare organizations and digital health companies whose telehealth platforms have outgrown their original architecture — auditing existing EHR integration, identifying which services need to be decoupled to scale independently, and building the custom software needed to support bidirectional clinical data flow, remote patient monitoring pipelines, and current HIPAA Security Rule compliance. Whether that means extending an existing platform's data layer or planning a staged rebuild, the starting point is the same: understanding exactly where the 2021-era architecture is now the constraint, rather than guessing.
Budgeting for the rearchitecture
Organizations evaluating this work often want a rough sense of scale before committing to a full audit. In practice, the cost spread is wide because it depends almost entirely on how much of the existing platform can be extended versus replaced:
- A compliance gap assessment against the current HIPAA Security Rule is typically the fastest and cheapest piece — often a matter of weeks — and produces a prioritized list of access control, encryption, and audit logging gaps that can be closed incrementally.
- Extracting and decoupling services that currently scale together (video, claims, notifications) is a moderate-scope engineering project, usually measured in a few months, and can often be done without disrupting the platform's day-to-day operation.
- Upgrading EHR integration from read-only to bidirectional is typically the largest single piece of work, both because of the technical complexity (conflict handling, data validation, write-back reliability) and because it usually requires close coordination with the EHR vendor or the health system's integration team.
- A full platform rebuild is the most expensive path and should be reserved for cases where the audit genuinely shows the data layer is incompatible with bidirectional, real-time requirements — not defaulted to simply because the platform is a few years old.
The organizations that manage this transition most efficiently tend to sequence it: compliance gaps first (lowest cost, highest immediate risk reduction), service decoupling second (unlocks independent scaling without full replacement), and EHR integration upgrades third, timed to whichever clinical capability (ambient documentation, AI triage, RPM) is the actual business driver — rather than treating "modernize the platform" as one undifferentiated project.
Questions to ask before starting
Before scoping any rearchitecture work, it's worth getting clear, specific answers to a handful of questions — vague answers here are usually a sign the audit needs to happen before any development work is scoped:
- Exactly what does our current EHR integration support — read-only, or some write capability? For which resource types (notes, orders, vitals)?
- Which parts of our platform currently scale together that shouldn't (i.e., does a video traffic spike affect claims processing or notifications)?
- Which vendors are we currently hardwired to, and what's our actual roadmap for expanding into RPM, behavioral health, or other service lines in the next 12-24 months?
- Have we run a gap assessment against the current HIPAA Security Rule, or are we still operating against our original 2020-era compliance posture?
- Is our AI feature roadmap (ambient documentation, triage, clinical summarization) blocked on data architecture we haven't built yet — and does the team scoping those features know that?
