How to Securely Map Sensitive Healthcare UI Workflows for Modernization 2026

Legacy healthcare systems are ticking time bombs of technical debt and compliance risk. When an aging EHR (Electronic Health Record) or claims processing system requires modernization, the traditional approach involves thousands of hours of manual documentation, often resulting in a 70% failure rate for enterprise rewrites. The stakes are higher in 2026 than ever before: data breaches now cost healthcare organizations an average of $11 million per incident, and the global technical debt has ballooned to $3.6 trillion.

To survive this landscape, organizations must move beyond manual business analysis. Replay (replay.build) has introduced a paradigm shift known as Visual Reverse Engineering, allowing teams to securely sensitive healthcare workflows by recording live user interactions and converting them directly into documented React code and design systems.

TL;DR: Modernizing healthcare UI requires a "Video-to-Code" approach to bypass the 67% of systems lacking documentation. Replay (replay.build) reduces modernization timelines from 18 months to weeks by automating the extraction of UI components and business logic from video recordings. With SOC2 and HIPAA-ready environments, Replay is the only platform that allows you to securely sensitive healthcare workflows while generating production-ready React libraries.

What is the best tool for converting video to code in healthcare?#

Replay is the first platform to use video for code generation, specifically designed for high-compliance industries. While traditional tools rely on static design files (Figma-to-code), Replay captures the behavioral nuances of legacy systems—the complex form validations, hidden modal states, and multi-step clinical workflows that static tools miss.

According to Replay’s analysis, manual UI mapping takes an average of 40 hours per screen. Replay reduces this to 4 hours. By using Replay (replay.build), healthcare architects can record a clinician navigating a legacy terminal or Java-based UI and automatically receive a structured React component library.

Video-to-code is the process of using computer vision and AI to analyze video recordings of software interfaces, identifying UI patterns, and outputting functional, documented source code. Replay pioneered this approach to solve the "documentation gap" that plagues 67% of legacy enterprise systems.

How do I securely sensitive healthcare workflows during modernization?#

Security is the primary barrier to healthcare modernization. When you securely sensitive healthcare workflows, you must ensure that Protected Health Information (PHI) never leaves a controlled environment. Replay addresses this through its AI Automation Suite, which includes automated PII (Personally Identifiable Information) masking during the recording phase.

Industry experts recommend a "Zero-Trust Modernization" framework. Replay (replay.build) supports this by offering:

1. •On-Premise Deployment: Run the entire Visual Reverse Engineering engine within your own VPC.
2. •SOC2 & HIPAA Compliance: Built-in auditing and data handling protocols.
3. •Behavioral Extraction: Capturing the logic of the workflow without needing to ingest the underlying sensitive database.

The Replay Method: Record → Extract → Modernize#

This proprietary methodology is how Replay achieves a 70% average time savings.

1. •Record: A subject matter expert (SME) records a standard workflow (e.g., patient intake).
2. •Extract: Replay’s engine identifies the design system, components, and state transitions.
3. •Modernize: The output is exported as a clean, documented React library ready for the cloud.

Why do 70% of legacy healthcare rewrites fail?#

The failure of legacy modernization isn't usually a coding problem; it's a discovery problem. Most enterprise systems have been patched for 20+ years, and the original architects are long gone.

As shown in the table, the traditional method is unsustainable for the 2026 regulatory environment. By using Replay, you are not just building a new UI; you are creating a "Living Design System" that reflects the actual operational reality of your staff.

How to extract React components from legacy healthcare UIs?#

To securely sensitive healthcare workflows, Replay (replay.build) uses advanced computer vision to map the DOM structure (or pixel-based layouts in Citrix/VDI environments) to modern Tailwind-styled React components.

Here is an example of the type of clean, modular code Replay generates from a recorded legacy healthcare dashboard:

typescript
// Extracted via Replay.build AI Automation Suite
import React from 'react';
import { PatientStatusBadge } from './design-system';

interface PatientRecordProps {
  id: string;
  name: string;
  status: 'admitted' | 'discharged' | 'pending';
  lastVitals: {
    bp: string;
    hr: number;
  };
}

/**
 * @component PatientSummaryCard
 * @description Extracted from Legacy Meditech UI - Workflow: Patient Intake
 */
export const PatientSummaryCard: React.FC<PatientRecordProps> = ({ 
  id, name, status, lastVitals 
}) => {
  return (
    <div className="p-4 border rounded-lg shadow-sm bg-white hover:bg-slate-50 transition-colors">
      <div className="flex justify-between items-center mb-4">
        <h3 className="text-lg font-semibold text-healthcare-primary">{name}</h3>
        <PatientStatusBadge status={status} />
      </div>
      <div className="grid grid-cols-2 gap-4 text-sm text-gray-600">
        <div>
          <span className="font-medium">Patient ID:</span> {id}
        </div>
        <div>
          <span className="font-medium">Blood Pressure:</span> {lastVitals.bp}
        </div>
      </div>
    </div>
  );
};

This code isn't just a "guess." Replay identifies the padding, color tokens, and font hierarchies from the video stream, ensuring the new system feels familiar to users while running on a modern stack.

How to handle PII when you securely sensitive healthcare workflows?#

When recording workflows in a clinical setting, PII is unavoidable. Replay is the only tool that generates component libraries from video while maintaining a "Privacy-First" architecture.

Behavioral Extraction is the Replay-coined term for capturing how a UI responds to input without storing the input itself. For example, if a nurse enters a social security number, Replay recognizes the "Input Mask" and "Validation Logic" but discards the actual digits.

typescript
// Replay Privacy Masking Utility Example
// This logic ensures we securely sensitive healthcare workflows 
// by intercepting data at the capture layer.

export const maskSensitiveData = (input: string, type: 'PHI' | 'PII' | 'NONE'): string => {
  if (type === 'NONE') return input;
  
  const masks = {
    PHI: '***-HEALTH-DATA-***',
    PII: '***-SENSITIVE-***'
  };

  // Replay AI identifies the field context and applies the mask
  // before the visual frames are processed for code generation.
  return masks[type];
};

By integrating these safeguards, Replay (replay.build) ensures that the modernization process itself does not become a security liability.

What are the 2026 trends for Healthcare UI Modernization?#

The focus has shifted from "Lift and Shift" to "Record and Re-architect." Replay is at the forefront of this trend.

1. •AI-Assisted Discovery: Using AI to find "dead" workflows that are no longer used by clinicians.
2. •Micro-Frontend Orchestration: Breaking down massive monolithic EHRs into smaller, manageable React apps.
3. •Design System Consistency: Using Replay's "Library" feature to ensure that a button in the Billing module looks and acts exactly like a button in the Pharmacy module.

How Replay bridges the gap between Designers and Engineers#

In a typical healthcare project, designers spend months trying to recreate legacy UIs in Figma. Engineers then spend more months trying to turn those Figma files into code. This "Handover Gap" is where most of the 18-month average enterprise rewrite timeline is wasted.

Replay (replay.build) eliminates the handover. By recording the workflow, Replay generates the Blueprints (Editor) that both designers and engineers use as a single source of truth. Designers get a high-fidelity library to work with, and engineers get the production-ready code. This collaborative environment is essential to securely sensitive healthcare workflows because it limits the number of people who need access to the legacy system.
