For many providers, medical applications are primarily about finding answers to clinical questions as rapidly as possible. However, a number of developers are exploring medical applications that resemble games. Games theory and gamification of medical education is still in its infancy, but more and more apps are being developed especially as the mobile technology platform continues to mature. The latest iPhone and Android devices are much more capable of high quality game play then even a generation or two ago. Previously on iMedicalApps, we discussed the apps from Medical Joyworks, a company based Sri Lanka who have made a name for themselves with Prognosis: Your Diagnosis, My Prognosis: Pregnancy and most recently, Clinical Sense. We liked the rich graphics and “role-playing” game function of their apps, but found some cases too easy or simply not enough variety for other specialties.

One of the latest diagnosis game apps to enter the scene is Human Dx. The app is the embodiment of the Human Diagnosis Project, a group based in San Francisco whose mission is “a worldwide effort to map any health problem to its possible diagnosis.” It claims to be the world’s first open diagnostic system. The Project was founded by medical and nonmedical providers from the World Health Organization, Facebook,, MIT, Harvard, UC Berkeley, etc. They seek to be a true “open” worldwide network of providers working on clinical diagnosis and improving the collective clinical reasoning of the medical profession. Pretty noble stuff. Details on the organization, software, etc. can be found here.

When you first download and open the app, it requires you to enter your cell phone number to receive a verification code. This may immediately put off some providers as you are taking a leap of faith that your personal information is safe with this organization. After you put in the verification code, you are asked to put in your name, academic institution, medical specialty, etc. After you have established your profile, the app immediately prompts you to solve your first clinical reasoning case. The app prompts you to build, revise and finalize your differential diagnosis for the case. The app then gives you feedback on how you did. The app “finally” shows you its homepage including your profile, the community profile, cases to solve, and most interesting the ability to contribute your own cases. You can also collaborate with providers all over the world who are part of the Project.

Let’s try out Human Dx to see how we can improve our clinical reasoning and contribute to the medical community. Login to iMedicalApps in order to view the following video review of Human Dx. Registration for iMedicalApps is free.

Evidence based medicine

Human Dx is a unique and perhaps even revolutionary approach to improve clinical reasoning across the international medical community via gamification of clinical cases. The cases are all “real life” from the medical community.

What providers would benefit from this App?

Students, residents, mid-levels, attending providers, nurses across all specialties. The app can help improve clinical reasoning for any medical provider.

    • Cases focused on differential diagnosis with limited ability for “complex” cases beyond the “initial” reveals.
    • Information about the app is lacking without going to the Human Dx Project website.
    • Not available for Android.
  • Overall

    An ambitious, polished app for solving clinical cases. This app should be used by all in academic medicine to improve and contribute to the clinical reasoning of the collective medical community.

  • Overall Score

    Initial setup takes a few moments, but the app is fast and intuitive for solving and building cases.

  • Multimedia Usage

    Ability to collaborate with providers the world over and create and add your own cases.

  • Real World Applicability

    The app provides “practice with reflection” on our clinical reasoning skills. No provider should miss the opportunity to try this. Seasoned attendings who find some content “too easy” can simply add “their toughest” cases to make this app appropriate for “learners” at any stage of practice.
