Building a medical app for doctors: An overview
How do you build a medical app for doctors? Such a project involves the following steps:
1. Define the scope for the overall app
Start with onboarding a competent project manager (PM), an experienced IT architect, and a team of business analysts (BAs) with experience in the healthcare industry. Decide on the features you will offer. I recommend the following:
- Build a web app, an Android app, and an iOS app.
- Offer features like Epocrates, and support English-speaking users in the US to start with.
You will likely launch a “Minimum Viable Product” with minimal features to test the market, subsequently, you will enhance the app. Consider using the Agile SDLC model for such projects, and learn more about Agile in “What is software development life cycle and what you plan for?”.
2. Prioritize features for your MVP
Determine the features you will offer in your MVP app by taking the following steps:
- Understand your customers and what constitutes “business value” for them, by conducting intense “discovery sessions”.
- Analyze how your planned features address specific customer pain points, with the help of tools like the “Pain and gain map”.
- Based on the above, prioritize features for your MVP using tools like the “prioritization matrix”.
Read our guide “5 tips to create a sleek MVP” for more insights.
3. Formulate a development approach geared towards success
Meticulous planning is the key to the success of this project, therefore, formulate an appropriate development approach. The following are my recommendations:
- Develop native iOS and Android apps since they offer the best user experience, performance, and security.
- Use a modern runtime environment like Node.js, which helps to develop scalable and performant web apps.
- You could launch your app in more geographies later, therefore, factor in app internationalization guidelines. Read about them in “The ultimate guide to mobile app internationalization”.
- A medical app will process “Protected Health Information” (PHI), therefore, plan to secure your app.
- Use managed cloud services platforms like “Platform-as-a-Service” (PaaS) and “Mobile-Backend-as-a-Service” (MBaaS), which will eliminate the task of IT infrastructure management for you.
- Implement core features by developing own APIs, and use market-leading 3rd party APIs to implement non-core features.
- Use a mobile device and browser lab on the cloud to enhance your test coverage.
You can learn about the value of this approach in “What is the best development approach to guarantee the success of your app?”.
4. Onboard and organize your development team
Onboard your development team and read our guide “How to find a good software developer” for help. You need to staff the following roles:
- UI designers;
- Web developers with Node.js skills;
- Android developers with Java skills;
- iOS developers with Swift skills;
- DevOps engineers.
Your team must collaborate and work cohesively for the success of the project, therefore, use the “Scrum” technique to organize it. Use an effective PM tool like Jira, and do the following:
- Form “Scrum teams”, i.e., small, cross-functional teams where developers and testers work together. The PM needs to perform the “Scrum Master” role.
- Empower the team sufficiently so that it can estimate requirements and plan them in iterations called “Sprints” in the scrum parlance.
- Ensure that the PM prioritizes creating value for users over mechanical processes, e.g., the PM should hold effective “Daily stand-up meetings” for project tracking.
- Build a transparent environment where collaboration with customers is valued. E.g., the team needs to demonstrate a functional app in “Sprint review meetings” to obtain approval from the business stakeholders.

5. Strategize for securing your app
Businesses processing PHI need to comply with stringent regulations like the “Health Insurance Portability and Accountability Act” (HIPAA) in the US. Information security is a key aspect of such regulations, therefore, strategize carefully about securing your app.
Do the following:
- Incorporate multi-factor authentication (MFA) instead of relying solely on passwords.
- Use strong encryption algorithms like AES-256.
- Utilize next-gen firewalls and antivirus solutions.
- Proactively mitigate top application security risks like injection, broken authentication, XML external entities (XXE), cross-site scripting (XSS), etc. You can read the “Open Web Application Security Project (OWASP) top 10 application security risks – 2017” report for guidance.
- Consider using cloud computing smartly, e.g., you can use a hybrid cloud deployment. Here, you will store sensitive data on a private cloud, however, you can run other workloads on a public cloud.
- Secure your APIs using various techniques like digital signatures, encryption, authentication, quotas, throttling, secure gateways, etc.
- Utilize real-time threat intelligence solutions.
- Instead of treating security and compliance testing as the last activity, proactively include it in your CI/CD pipeline with the help of “compliance-as-code”. Read “Compliance-as-code: Addressing compliance challenges through automation” for more insights.
6. Sign-up for the right PaaS and MBaaS platforms
PaaS platforms can help you to expedite web app development since they offer the following advantages:
- PaaS platforms manage the cloud infrastructure, networking, operating system, middleware, and runtime environment, therefore, you can focus on development.
- As I have explained in “10 top PaaS providers for 2020”, PaaS platforms enable you to integrate APIs, add database resources, and use robust DevOps tools.
- Scaling a web app is easier when you use a PaaS platform.
Sign-up for AWS Elastic Beanstalk, which the PaaS offering from AWS.
You can expedite mobile app development with an MBaaS platform. Such platforms offer many advantages, e.g.:
- They manage the cloud infrastructure and persistent storage, therefore, you don’t need to build and manage the mobile backend.
- MBaaS platforms enable you to integrate APIs, moreover, they help you to implement security features.
- Implementing features like user management and “push notifications” is easier with an MBaaS platform, furthermore, you can easily scale your mobile app.
Use AWS Amplify, i.e., the MBaaS offering from AWS.
7. Find market-leading 3rd party APIs to implement the non-core features
Displaying drug interaction and medical diagnostics information is important, however, it’s not a core feature. Similarly, you need the “push notifications” feature, however, it’s a non-core feature.
I recommend that you use the following market-leading 3rd party APIs:
- Use the Infermedica medical API for displaying diagnostics information in your app. The Infermedica AI inference engine can analyze patient data and provide a list of likely conditions and relevant observations. Read the Infermedica documentation to learn how to use this API.
- Sign-up with Wolters Kluwer and use its “All Drugs APIs” solution. This solution is broad and includes APIs like “Adverse Drug Effects”, “Drug Allergy”, “Drug Interactions”, etc. Consult the Wolters Kluwer “Resources” webpage to learn how to use these APIs.
- Use the Twilio “Programmable SMS” offering, which is a bulk-SMS API solution to help you to implement the “push notifications” feature. Read “Messaging services and Copilot” to learn how to use this API solution.
8. Develop APIs for your core features
You ought to develop APIs for implementing the core features that doctors will use, and I recommend that you develop RESTful APIs. Take the following steps:
- Use Postman for API development and testing, moreover, use Swagger for documenting the APIs.
- Host the APIs using your AWS account, and use robust database solutions like PostgreSQL and MongoDB for API development.
- Manage the development, staging, and production environments effectively.
- Secure your APIs using the techniques that I have suggested earlier.
- Design URL paths meaningfully, moreover, formulate effective rules for API requests and responses.
