Hospital Management System

Introduction

This is a simple example of how to model a hospital management system using Mongoose. We will be using the following schema:

Patient
Doctor
Hospital
Medical Report
Address

The Folder structure will look like this:

address.models.js
doctor.models.js
hospital.models.js
medical_report.models.js
paitent.models.js

Patient

model/patient.models.js

import mongoose from "mongoose";
 
const patientSchema = new mongoose.Schema(
  {
    name: { type: String, required: true },
    age: { type: Number, required: true },
    diagnosedWith: { type: String, required: true },
    bloodGroup: { type: String, required: true },
    gender: {
      type: String,
      required: true,
      enum: ["M", "F", "Others"],
    },
    address: {
      type: mongoose.Schema.Types.ObjectId,
      ref: "Address",
      required: true,
    },
    contact: { type: Number, required: true },
    email: { type: String, required: true },
    medicalReports: [
      {
        type: mongoose.Schema.Types.ObjectId,
        ref: "MedicalReport",
      },
    ],
    whichHospital: {
      type: mongoose.Schema.Types.ObjectId,
      ref: "Hospital",
      required: true,
    },
  },
  { timestamps: true }
);
 
export const Patient = mongoose.model("Patient", patientSchema);

Doctor

model/doctor.models.js

import mongoose from "mongoose";
 
const doctorSchema = new mongoose.Schema(
  {
    name: {
      type: String,
      required: true,
    },
    specialization: {
      type: String,
      required: true,
    },
    salary: {
      type: Number,
      required: true,
    },
    qualification: {
      type: String,
      required: true,
    },
    contact: {
      type: Number,
      required: true,
    },
    email: {
      type: String,
      required: true,
    },
    experience: {
      type: Number,
      required: true,
      default: 0,
    },
    worksInHospital: [
      {
        type: mongoose.Schema.Types.ObjectId,
        ref: "Hospital",
        required: true,
      },
    ],
    address: {
      type: mongoose.Schema.Types.ObjectId,
      ref: "Address",
      required: true,
    },
  },
  { timestamp: true }
);
 
export const Doctor = mongoose.model("Doctor", doctorSchema);

Hospital

model/hospital.models.js

import mongoose from "mongoose";
 
const hospitalSchema = new mongoose.Schema(
  {
    name: { type: String, required: true },
    address: {
      type: mongoose.Schema.Types.ObjectId,
      ref: "Address",
      required: true,
    },
    contact: { type: Number, required: true },
    email: { type: String, required: true },
    doctors: [
      {
        type: mongoose.Schema.Types.ObjectId,
        ref: "Doctor",
      },
    ],
    patients: [
      {
        type: mongoose.Schema.Types.ObjectId,
        ref: "Patient",
      },
    ],
    specialization: [
      {
        type: String,
        required: true,
      },
    ],
  },
  { timestamps: true }
);
 
export const Hospital = mongoose.model("Hospital", hospitalSchema);

Medical Report

model/medical_report.models.js

import mongoose from "mongoose";
 
const medicalReportSchema = new mongoose.Schema({}, { timestamps: true });
 
export const MedicalReport = mongoose.model(
  "MedicalReport",
  medicalReportSchema
);

Address

model/address.models.js

import mongoose from "mongoose";
 
const addressSchema = new mongoose.Schema({
  street: { type: String, required: true },
  city: { type: String, required: true },
  state: { type: String, required: true },
  country: { type: String, required: true },
  pincode: { type: String, required: true },
});
 
export const Address = mongoose.model("Address", addressSchema);
