Client Overview
A multi-specialty health system operating 12 clinic locations across a metropolitan area, serving over 80,000 patients annually. The system includes primary care, cardiology, orthopedics, OB/GYN, pediatrics, and urgent care — each previously operating with fragmented patient-facing technology.

Client Testimonial
Before Taction’s portal, our patients had to call us for everything — scheduling, refills, results. Now 62% of our patients handle those tasks themselves through the portal. The phone volume drop alone justified the investment.” — VP of Digital Health,
The Challenge
The health system faced several interconnected problems. Each clinic location used a different patient-facing interface — some had basic portals bundled with their EHR, others had none at all. Patients visiting multiple locations had to manage separate logins, separate message threads, and separate appointment systems. The result was abysmal portal adoption (under 12% of active patients) and a front desk overwhelmed with phone calls for tasks that should have been self-service.
Specific pain points included no unified patient identity across locations, patients could not see lab results from one clinic while logged into another’s portal, prescription refill requests required phone calls during business hours, appointment scheduling was phone-only at 8 of 12 locations, secure messaging was unavailable or unreliable, the existing portal was not mobile-friendly, and several locations had compliance gaps in how PHI was transmitted between the portal and backend systems.
The Solution
Taction built a unified, branded patient portal that replaced all 12 fragmented interfaces with a single mobile-first platform.
Technical Architecture
Frontend: React-based responsive web application + React Native mobile apps (iOS and Android). Mobile-first design with three-click-or-less workflows for all common tasks.
Backend: Node.js API layer with PostgreSQL database. RESTful API architecture with role-based access controls and comprehensive audit logging.
EHR Integration: The health system ran Epic at 9 locations and athenahealth at 3 locations. Taction built a unified integration layer using Mirth Connect that normalized data from both EHR platforms into a single patient experience. FHIR R4 APIs handled patient record access, appointment scheduling, and lab results. HL7v2 ADT feeds maintained real-time patient demographic synchronization.
Identity Management: Unified patient identity with SSO across all locations. Patients create one account that works everywhere. MFA enforced for all logins (2026 HIPAA Security Rule compliance).
Features Delivered
Health record access across all 12 locations (full USCDI dataset via FHIR), online appointment booking with real-time provider availability at any location, lab and imaging results with normal range indicators and trending, prescription refill requests routed to the correct pharmacy, secure messaging with care team (threaded, asynchronous, with read receipts), billing statements and online payment (Stripe integration with PCI compliance), telehealth visit launching (integrated with the health system’s telemedicine platform), proxy access for caregivers and parents, multi-language support (English, Spanish), and push notifications for appointment reminders, new results, and message alerts (no PHI in notification content).
HIPAA Compliance
Full HIPAA compliance implementation including AES-256 encryption at rest, TLS 1.2+ in transit, MFA for all users, RBAC with least-privilege enforcement, tamper-proof audit logging retained for 6+ years, BAAs executed with all infrastructure and service providers, and annual penetration testing and vulnerability assessments.
Technologies Used
Results
The health system estimates that the phone call volume reduction alone saved 3.5 FTE front desk positions across the 12 locations — approximately $175,000 annually in staffing costs. The portal paid for itself within the first year of operation.
