Hospital ERP Backend

Hospital ERP App Backend Template
Hospital Operations, Admissions, and Audit Logging

Q: What is a Hospital ERP backend?

A Hospital ERP backend is a structured BaaS schema and API for core hospital operations such as departments, beds, staffing, rotations, admissions, and audit logging.

Q: What does the Hospital ERP template include?

It includes Department, Bed, StaffProfile, Rotation, Patient, Admission, and AuditLog, plus ER diagram, API playground, JSON schema, and an AI Agent prompt.

Q: Why use Back4app for a hospital operations app?

Back4app provides managed database, auth, API generation, real-time options, and flexible schema evolution so teams can ship hospital workflows without maintaining backend infrastructure.

Q: How do I load bed occupancy and admissions with Flutter?

Use Department, Bed, and Admission queries to build occupancy dashboards and placement screens, then map results into your Flutter state layer.

Q: How do I create an admission with Next.js server actions?

Use a server action to create an Admission object with patient and department pointers, then optionally attach a bed after validating availability.

Q: Can React Native cache bed and staffing data offline?

Yes. Enable Local Datastore and pin Department, Bed, and selected Rotation records so operational views remain usable during intermittent connectivity.

Q: How do I prevent double-booking a bed?

In Cloud Code beforeSave for Admission or Bed updates, check for active admissions using the same bed and reject conflicting assignments.

Q: What is the best way to show department rosters on Android?

Query StaffProfile and Rotation by department and date window, then combine them in your repository or ViewModel for a shift-aware roster view.

Q: How does the audit logging flow work end-to-end?

When a user performs a key action such as assigning a bed or updating a rotation, the app writes the operational record and then stores a related AuditLog entry with actor, action, entity context, and payload metadata.

Q: How should I model patient movement between departments?

Use Admission status changes and department or bed updates to represent transfers, and store each important transition in AuditLog so the movement history is traceable.

Overview

A hospital ERP product needs accurate visibility into beds, departments, admissions, and staff movement across shifts.

This template defines Department, Bed, StaffProfile, Rotation, Patient, Admission, and AuditLog with ownership rules and extensible workflows so teams can implement hospital operations software quickly.

Core Hospital ERP Features

Every technology card in this hub uses the same hospital ERP backend schema with Department, Bed, StaffProfile, Rotation, Patient, Admission, and AuditLog.

Department management

Department class stores names, codes, floors, and operational grouping for wards and services.

Bed inventory and occupancy

Bed class tracks bed number, ward, department, and status such as available, occupied, cleaning, or maintenance.

Staff profiles and roles

StaffProfile stores user link, role, license identifiers, and department affiliation.

Staff rotations and shifts

Rotation class stores staff member, department, schedule window, and shift status.

Patient admissions and bed assignment

Admission links patient, department, assigned bed, timestamps, and lifecycle status.

Centralized audit logs

AuditLog records actor, action, target entity, and payload metadata for traceability.

Why Build Your Hospital ERP Backend with Back4app?

Back4app gives you the core operational building blocks for hospital software so your team can focus on workflows, approvals, and clinical coordination instead of backend plumbing.

•Bed and admission management: Model departments, beds, patients, and admissions in linked classes that support occupancy, transfer, and discharge flows.
•Staff scheduling structure: Track staff profiles and department rotations with clear date ranges, statuses, and role-aware assignment logic.
•Auditability + API flexibility: Use audit logs for traceability while keeping REST and GraphQL available for admin portals, ward screens, and mobile apps.

Ready to build

Create a hospital ERP backend on Back4app with this exact schema and behavior.

Schema:
1. Department: name (String, required), code (String, required), floor (Number, optional); objectId, createdAt, updatedAt (system).
2. Bed: bedNumber (String, required), ward (String, required), status (String: available, occupied, cleaning, maintenance, required), department (Pointer to Department, required); objectId, createdAt, updatedAt (system).
3. StaffProfile: user (Pointer to User, required), role (String, required), licenseNumber (String, optional), department (Pointer to Department, required); objectId, createdAt, updatedAt (system).
4. Rotation: staff (Pointer to StaffProfile, required), department (Pointer to Department, required), shiftStart (Date, required), shiftEnd (Date, required), status (String: scheduled, active, completed, cancelled, required); objectId, createdAt, updatedAt (system).
5. Patient: mrn (String, required), fullName (String, required), dateOfBirth (Date, required); objectId, createdAt, updatedAt (system).
6. Admission: patient (Pointer to Patient, required), department (Pointer to Department, required), bed (Pointer to Bed, optional), admittedAt (Date, required), dischargeAt (Date, optional), status (String: pending, admitted, transferred, discharged, required); objectId, createdAt, updatedAt (system).
7. AuditLog: actor (Pointer to User, required), action (String, required), entityType (String, required), entityId (String, required), payload (Object, optional); objectId, createdAt, updatedAt (system).

Security:
- Use ACL/CLP by role. Only authorized staff can manage admissions, bed assignments, and rotations. AuditLog records must be append-only for standard users.

Auth:
- Sign-up, login, logout for staff users.

Behavior:
- List departments and beds, create admissions, assign beds, schedule rotations, and write audit logs for important actions.

Deliver:
- Back4app app with schema, ACLs, CLPs; frontend for department dashboards, bed occupancy, admission workflows, staffing schedules, and audit history.
