Covid

Covid is a web application which aims to facilitate covid-19 patients' self-monitoring at home via forms sent by SMS.

Demo : video

Main configuration

Installation

It's a Rails v6.0 application which runs on Ruby v2.6+.

It requires a limited number of dependencies to run locally:

• PostgreSQL (v10.4+)
• Redis (Sidekiq)
• Headless Chrome (integration specs)
• NodeJS v12 (LTS)

The best way to install them is to use Homebrew:

brew update
brew install rbenv ruby-build postgresql redis
brew cask install chromedriver

Ruby

rbenv install 2.6.5
gem install bundler

Git

git clone git@github.com:lifen-labs/covid.git && cd covid
bundle exec install && yarn install
bundle exec rails db:setup

Environment variables

cp .env.example .env

Twilio

We use Twilio's API to send SMS:

• TWILIO_ACCOUNT_ID (required)
• TWILIO_AUTH_TOKEN (required)
• TWILIO_PHONE_NUMBER (required)

How to create a text messaging account with Twilio ?

Slack

We use Slack to monitor failed SMS:

• SLACK_HOOK_URL (optional)

Starting a local server

heroku local

Then visit http://localhost:5000/admin/ with the seeds credentials: admin@example.com / password.

Specs

bundle exec rspec spec/

or

bundle exec guard

Deployment

The fastest way to deploy covid is using Heroku:

:warning: Disclaimer Heroku might not be suitable to host healthcare datas in your country. We are providing this deploy link on Heroku because we think it's the easiest way to deploy a web application ;) :warning:

Data structure

Once signed in to the app via login/password, an AdminUser can:

• manage a CommandCenter : the app can be deployed once and used in multiple locations (TODO: add an authorisation framework like Pundit to manage access levels)
• onboard a Patient
• manually create a StandardSurvey; otherwise, an automated process creates one every 24 hours.

When a StandardSurvey is created, an SMS is sent with a secret temporary link. The Patient can then fill the form directly on his phone. Once the StandardSurvey is submitted, the app sets the operational status :

• green : all good
• yellow : default status, still all good
• orange : a healthcare professional needs to check the survey results
• red : a healthcare professional needs to call the patient

Both orange and red statuses require an action from the AdminUser. Each action has to be recorded through a mandatory comment within the app.
