“Diagnosaurus® is a valuable quick reference tool that contains over 1,000 differential diagnoses. Available for iOS and Android, this application helps healthcare professionals reach accurate diagnoses with speed and confidence at the point of care.” From Unbound Medicine website. 

Diagnosaurus allows the user to provide differential diagnoses of symptoms, signs and diseases. Users can also view entries by organ system as well. Diagnosaurus also offers both etiology and differential diagnoses for various terms. Extremely limited view of topics in the “Free Preview” version of this app.

Features

Notes

None

Part 1: Editorial committee, content updates, and evidence grading

Author (Roni F. Zeiger, MD) and publisher information (McGraw-Hill Education) are listed on the app, the app stores’ and the website. There is no listing of any editorial, peer-review committee or institutional/organizational affiliations in any of the aforementioned sources.  As such, it is difficult to provide evidence grading to preview version of the Diagnosaurus app.

Part 2: Source and authorship information for 3 entries

Links to relevant evidence s-based studies are only provided in the subscription version, however, they are not provided for the entries in the preview version of the app. The developer and author of the app (Dr. Roni F. Zeiger) earned his MD at Stanford University and completed his internal medicine residency at the University of California. According to the TEDMED website he has written extensively in the medical sciences and is an authority in social media and health.

Organization of information

There are four main sections: “All Entries”, “Organ Systems”, “Symptoms” and “Diseases”. The term in each section is listed alphabetically. Each term contains information on the etiology and differential diagnoses in the section DDX.

Extremely limited view and content of topics in the “Free Preview” version of this app. The subscribed version contains the complete list of entries. The subscribed version also contains outside references and more cross links to other conditions for each entry.

Navigation

This App was very easy to navigate and was very intuitive. Users are able to browse entries in the four different categories alphabetically. Each entry has a related DDx entry for differential diagnoses. 

The free version of the App is extremely limited. To access most entries and the related DDx’s, users will have to purchase a subscription to the App.
