Description 👈

It's a web application for managing hospitals rooms and determining the patient's priority for isolation. The app provides a centralised hub for managing the patients and planning their distribution across hospital’s rooms.

It allows nurses to keep track of the patients and their diseases in real time and to have an overview over the patients and rooms, and better manage the rooms assignment across patients.

How to use it 📖

Dashboard

Data about patients and rooms is available here. The page is split into three tables.

To clear the red warning sign you need to go on the patient’s personal page. To do that, you have to double click on his name. By clicking on the ‘Update button’ on the bottom of the page, the patient’s diagnosis in updated for the next 24 hours (consequently, the red warning sign disappears).

Add patient page

You can add a new patient in the system with his personal details and his diseases. The application automatically computes the score of the patient based on the entered diseases

Patient page

Double click on a patient name on the dashboard to get here.

Database

Databse Schema

The available application is connected to a MongoDB database online. If you want to change the database to another one, you need to go: NHS app folder -> server -> db -> mongoose.js

Inside the file, you need to change the database link from mongoose.connect("mongodb://admin:[email protected]:45220/nhs-app"); to mongoose.connect("your-database-link");

REST Apis

The backend and frontend communicate through REST Apis. On the frontend, we make Ajax requests using jQuery to the following routes:

URI	Returns
/app/getdiseases	returns information about all diseases in the system
/app/getpatients	returns information about all patients in the system
/app/getpatient/:hospitalNumber	returns information about a specific patient
/app/getrooms	returns information about the rooms in the system

Known bugs 🐛

1. On some mobiles devices (iPhone, iPad) assigning rooms to patients is not working because mobile browsers doesn’t interpret the double-click. Also, the user can’t enter the patient's page because of the same reason. However, on LG mobile devices this feature works.
