Cardiology Suite Backend

Cardiology Suite App Backend Template
Streamline ECG report storage and facilitate cardiac rehab exercise logging and patient communication.

Q: What is a Cardiology Suite backend?

A Cardiology Suite backend serves as a structured BaaS schema and API framework for patient-facing capabilities such as ECG report management, rehabilitation tracking, messaging, and auditing.

Q: What does the Cardiology Suite template encompass?

It includes schema definitions for ECGReport, CardiacRehabLog, PatientMessage, and AuditLog classes, alongside ER diagrams, an API playground, JSON schemas, and an AI Agent prompt for rapid deployment.

Q: Why choose Back4app for a cardiology application?

Back4app offers managed services for data storage, authentication, real-time capabilities, and seamless integration, permitting teams to concentrate on user experience and compliance without worrying about infrastructure.

Q: How do I retrieve the latest ECG report and its provider in a single query?

Employ GraphQL for executing nested requests or REST queries that include pointer expansion parameters for fetching the ECG report along with its respective provider details in one call.

Q: What is the process for marking a message as read?

Update the PatientMessage.status to 'read', ensuring the update corresponds to the recipient of the message; an AuditLog entry may also be written for record-keeping purposes.

Q: Can React Native maintain cached rehabilitation logs for offline access?

Yes, by enabling Local Datastore, you can pin CardiacRehabLog snapshots and implement logic for merging updates once connectivity is restored.

Q: How do I avoid unauthorized sharing of ECG PDFs?

Utilize signed URLs with short expiration times, enforce access controls through ACLs/CLPs, and refrain from including sensitive PHI in easily accessible logs.

Q: What is the recommended method for displaying rehab context in mobile applications?

Execute queries for both CardiacRehabLog in parallel with PatientMessage and ECGReport data to present a unified view of patient progress and communications, optionally pinning upcoming rehabilitation sessions for offline access.

Q: How does the audit logging system operate end-to-end?

AuditLog entries are automatically generated when significant actions occur (e.g., publishing an ECG report, saving a rehabilitation log, sending messages). AuditLog captures the identity of the actor, the action, the related entity, and any relevant payload for future review.

Q: What is the way to ensure patient acknowledgment for a rehabilitation plan?

Incorporate an acknowledgment field in the CardiacRehabLog schema; allow only suitable roles to set this acknowledgment, creating an AuditLog entry to log the action.

Key Takeaways

Deploy a cardiology-focused backend with strong data protections, thorough logging of exercise and recovery sessions, and patient communications to allow your product team to concentrate on enhancing user experience.

Patient-focused data model — Separate ECG reports, rehabilitation logs, and messages but interlink them for clear provenance and accessibility.
Secure messaging — Facilitate patient and provider communications with threaded messages and secure read receipts.
Versioned ECG reports — Store each ECG report version and track performance metrics over time.
Rehabilitation log tracking — Manage structured cardiac rehabilitation records, doctor involvement, and version histories.
Compliance-friendly logging — Centralized AuditLog class tracks sensitive events for compliance audits and reviews.

Overview

Cardiology applications require rigorous data protection, audit trails for patient interactions, and the reliable delivery of sensitive information such as ECG results and rehabilitation records.

This template defines ECGReport, CardiacRehabLog, PatientMessage, and AuditLog with ownership and permission models so developers can implement cardiology solutions securely and efficiently.

Core Cardiology Suite Features

Every technology card in this hub utilizes the same cardiology suite backend schema with ECGReports, CardiacRehabLogs, PatientMessages, and AuditLogs.

ECG Report Management

ECGReport stores patient ECG results, report types, metadata, and provider links.

Cardiac Rehabilitation Logs

CardiacRehabLog manages patient rehab session logging, provider involvement, and session summaries.

Secure Patient Messaging

PatientMessage supports threaded communications with attachments, visibility status, and timestamps.

Comprehensive Audit Logs

AuditLog captures actions taken by users on sensitive records and operations.

Why Build Your Cardiology Suite App Backend with Back4app?

Back4app simplifies backend operations—providing security, data persistence, APIs, and real-time features—allowing you to devote time to the patient experience, privacy mechanisms, and clinical integrations.

•Secure clinical data handling: Built-in authentication and access control structures ensure only authorized users can access ECG reports, rehabilitation logs, and messaging.

Security and Permissions

How ACL, CLP, and encryption strategies secure ECG reports, cardiac rehab logs, messages, and audit logs.

Role-based access and ownership

Implement ACLs so patients access only their ECG reports and logs while providers can manage assigned patients' data; CLPs prevent unauthorized operations.

Encrypted data and attachments

Store sensitive files (ECG reports, logs) behind secured URLs and use storage encryption for at-rest data protection.

Append-only audit trails

Automate the creation of AuditLog entries through server-side Cloud Code for additional security on historical compliance records.

Schema (JSON)

Build with AI Agent

Use the Back4app AI Agent to generate a Cardiology Suite app from this template, including backend schema, ACLs, and starter frontend integration.

Back4app AI Agent

Ready to build

Create a Cardiology Suite backend on Back4app with the following structure:

Schema:
1. ECGReport: patient (Pointer to Patient, required), reportType (String, required), resultData (Object), reportedAt (Date, required); objectId, createdAt, updatedAt.
2. CardiacRehabLog: patient (Pointer to Patient, required), provider (Pointer to Provider, required), sessionDetails (Object), status (String: upcoming, completed), effectiveFrom (Date), effectiveTo (Date); objectId, createdAt, updatedAt.
3. PatientMessage: sender (Pointer to User, required), recipient (Pointer to User, required), threadId (String, required), body (String), status (String: sent, delivered, read), sentAt (Date); objectId, createdAt, updatedAt.
4. AuditLog: actor (Pointer to User, required), action (String, required), entityType (String, required), entityId (String, required), payload (Object, optional), createdAt (Date); objectId, createdAt, updatedAt.

Security:
- Enforce ACLs so patients view their ECG reports and logs; providers see assigned patients. Leverage Cloud Code for secure transaction processes and to write AuditLog entries server-side.

Auth:
- Enable user registration for patients and providers; role-based assignment; secure authorization and session management.

Behavior:
- Patients log in, retrieve ECG report updates and log rehabilitation sessions, and send messages to their care providers. Providers will upload ECG results and manage sessions; the system will track events via AuditLog entries.

Output:
- Back4app cardiology app with complete schema, handling permissions, Cloud Code hooks for CRUD operations, and ready-to-use integration code for patient and provider interfaces.
