Appointment Management
Structured appointment workflows capture required patient, date, and testing information while status filters, referrals, and downstream handoffs connect appointment creation with later testing activity.
Clinical Point-of-Care Testing & Compliance Platform
A comprehensive Point-of-Care Testing Software solution that centralizes clinical testing workflows, appointments, safety prerequisites, staff training, environmental compliance, employee administration, audit history, facility documents, and interoperable healthcare data synchronization.
Project Overview
The solution is a role-based Clinical Testing Platform supporting Facility Admins, Merchant Admins, Supervisors, and Operators across point-of-care testing operations. It coordinates patient appointments, mandatory safety checks, patient records, employee permissions, role-specific training, environmental storage monitoring, file sharing, immutable histories, and external healthcare synchronization. Docker-based orchestration, Google authentication and messaging, and HAPI FHIR support the environment, replacing fragmented operational workflows with a traceable platform designed around facility-level testing and public-health compliance.
Business Challenges We Addressed
Unstable Existing Services
Several worker services contained unresolved onboarding issues while the email service repeatedly restarted because required Google OAuth credentials were not being loaded correctly.
Fragmented Development Environment
Developers lacked complete local access to every frontend and backend component, making end-to-end workflow replication and coordinated debugging more difficult.
Employee Dependency Integrity
Changing or removing staff roles could affect tests, devices, clinical records, and downstream relationships, requiring safeguards against destructive changes to dependent operational data.
Ineffective Training Assignments
Legacy Moodle workflows assigned identical courses tenant-wide instead of matching training to individual roles and the specific tests each facility performed.
Environmental Compliance Controls
Storage temperatures and humidity ranges required controlled, non-editable standards so users could not modify compliance thresholds governing devices, consumables, and stored testing material.
Clinical Traceability
Healthcare workflows required HL7 FHIR Integration and immutable historical records capable of showing what changed, when it changed, and who performed each modification.
How We Architected the Solution
Ditstek strengthened the POCT Software environment through containerized orchestration, controlled feature delivery, role-aware training, fixed environmental baselines, historical versioning, facility-scoped documents, and interoperable healthcare synchronization.
Stabilized Local Orchestration
Docker Compose coordinates worker services and frontend applications while authenticated startup workflows establish a more repeatable development environment for participating engineering teams.
Controlled Feature Development
Dedicated frontend and backend branches isolated quality-control changes, allowing temperature and timeout fields to be added safely without destabilizing unrelated functionality.
Focused Clinical Scope
Payments, insurance billing, external patient notifications, patient self-service, broad EMR connectivity, and advanced cross-facility sharing remained outside scope to prioritize core testing workflows.
Role-Specific Training Governance
Course administration moved to System Admin while training assignments became linked to individual roles and specific tests instead of assigning identical programs tenant-wide.
Immutable Environmental Rules
Storage categories use system-defined temperature and humidity ranges that cannot be edited by normal user roles, creating consistent environmental compliance baselines.
FHIR-Based Traceability
FHIR Provenance resources provide a standardized, non-invasive mechanism for external audit history and medico-legal traceability across synchronized clinical information.
Core Platform Capabilities
This Healthcare Compliance Software environment combines patient workflows, employee administration, training, storage monitoring, facility documentation, immutable history, and interoperable data synchronization to support controlled point-of-care operations.
Mandatory Safety Checks
Required PPE, hygiene, test-area, device, reagent, and waste-disposal checks must be completed before users can proceed from appointment preparation into testing workflows.
Patient Record Management
Structured personal, patient, and emergency-contact forms apply validation rules, photo handling, required fields, and existing role controls when creating patient records.
Employee and Role Management
Admins manage Operators and Supervisors with role, status, identity, contact, and dependency controls while soft deletion protects records associated with existing operational data.
Automated Training Compliance
Course assignments follow test and role requirements while per-test lockouts prevent unqualified staff from performing affected procedures without unnecessarily blocking other approved tests.
Environmental Storage Compliance
Temperature and humidity readings are compared against standardized storage ranges, creating alerts and immutable histories whenever monitored devices or consumables experience out-of-range conditions.
Facility File Sharing
Documents remain scoped to individual facilities with differentiated administrator and staff permissions, searchable metadata, lifecycle status controls, download access, and comprehensive action auditing.
Immutable Clinical History
Versioned history tables preserve create, update, and delete snapshots with timestamps, change reasons, user information, version numbers, and complete JSONB records.
FHIR Synchronization
Entity updates produce FHIR Provenance payloads sent to a HAPI FHIR server, supporting Healthcare Workflow Automation with standardized downstream traceability.

Measurable Business Impact
Unified Clinical Operations
Appointments, testing prerequisites, employees, training, environmental compliance, documents, and history can operate within one structured facility-focused workflow instead of disconnected processes.
Stronger Compliance Traceability
Immutable history records preserve detailed changes to important clinical and operational entities, providing administrators with clearer evidence of past system activity.
More Targeted Staff Training
Training requirements follow specific tests and staff roles, avoiding unnecessary tenant-wide lockouts while preventing users from performing procedures for which training remains incomplete.
Protected Environmental Standards
Fixed storage thresholds and historical readings make deviations easier to identify, investigate, and associate with affected devices, consumables, timestamps, and storage locations.
Safer Employee Lifecycle Changes
Dependency-aware deletion and role management reduce the risk that personnel changes accidentally break existing clinical tests, records, devices, or operational relationships.
Standardized Healthcare Interoperability
FHIR Provenance synchronization establishes a Healthcare Interoperability foundation for clinical histories and medico-legal traceability without modifying primary operational resources.
