    Step 3: Designing the Medical App

    Times have changed, and it is better that legacy healthcare systems are bade goodbye. The deepest concern that medical apps have helped to overcome is reduce the amount of physical paperwork that not only consumes time, but also delays quality care.


    Just like any other app, a healthcare app demands an intuitive user interface with a seamless flow of control to provide utmost user satisfaction.

    Considering the amount of data and the quality of service medical apps aim for, a well-researched and planned effort and best practices should go into designing a healthcare app.

    Quick tips for design thinking in healthcare:

    • It should be customer centric and focused on consistency.
    • It should simplify usability and conform with safety specifications.
    • It should deliver important information with less number of interactions.
    • Ideate and iterate to simplify process workflows.
    • Understand the pain-points of your users to provide seamless experience.

    Step 4: Planning For a Globally Secure Architecture

    Medical records containing patient healthcare data is worth millions of dollars in the dark world of cyber-crime. Healthcare data suffers a vulnerability risk to attacks in any part of the world. To curb this menace, national regulatory bodies have set up rules and regulations that safeguard healthcare applications from a potential breach.
    To comply with these rules, your medical app should consider:

    • Considering the scope of healthcare data and whether your app transmits or stores any sensitive data.
    • Geographical security frameworks to comply with world-wide information security standards.
    • A phased implementation of the app’s architecture as per the risk assessment for the features to be implemented.

    1. Privacy Rules in Different Regions

  • United States
  • Any healthcare application that transmits, records or stores Protected healthcare information (PHI) of a patient must comply with the Health Insurance Portability and Accountability Act (HIPAA) managed by the United States Department of Health and Human Services (HHS) and enforced by the HHS’ Office for Civil Rights. It encapsulates the following set of rules:

    • Privacy Rule
    • Security Rule
    • Enforcement Rule
    • Breach Notification Rule

    Unauthorized access, hacking/IT incidents and theft were the major reasons behind the HIPAA data breaches reported in 2016 and served hefty fines to the governing authority. So if you are planning a medical app for your business, keep in mind that a disclosure of any kind can lead to massive payoff. To avoid any HIPAA violation in the US, you should be aware of the ways to ensure your app is HIPAA compliant.

  • The European Union
  • If your app is targeted for audience in the European Union, it must be compliant with the Data Protection Directive 95/46/EC that regulates the processing and free movement of data. This Directive will soon be replaced by the EU General Data Protection Regulation (GDPR) by May 2018. It revises the existing data protection policies that handles how companies must handle personal data online.

  • The United Kingdom
  • Medical apps in UK come under the regulation of the Data Protection Act of 1988. This Act governed by the NHS enforces fundamental principles of personal data processing, storage and transmission in the UK.

  • Canada
  • The Canadian government tackles healthcare data privacy both at the federal and provincial level. The Personal Information Protection and Electronic Documents Act (PIPEDA) regulates all personal data which includes healthcare specific patient privacy. If you plan to build a medical app to be used in Canada, you would also need to make sure it complies with provincial security standards.

    Similarly, laws in Asia Pacific region, Australia, New Zealand and other countries vary and make sure your app adheres to country specific guidelines to avoid any penalty.

    Step 5: Getting Started with App Development
