- December 8, 2015 at 11:40 pm #76560
I would like to request a review of my iOS app DxLogic.
It is project I have been developing over the past 2 years. It’s a database of over 800 likelihood ratios of tests (history, radiology, physical exam etc.) spanning most specialities. I was spurred to create this resource as I found that LRs are a great idea in theory, but in practice, it’s so hard to actually remember and apply them all at the point-of-care. My resource not only contains hundreds of LRs but will actually do all the math of calculating the post-test probabilities for you.
There are some other app databases of LRs (Diagnose, SnapDx), but none I found were very easy to navigate and they only include the JAMA articles. My app is categorized for easy navigation and contains LRs from lactate for mesenteric ischemia (surprisingly not that great!) to EKG findings for cardiac amyloidosis. Furthermore, no other app states 95% confidence intervals for their data. My resource is also the first to suggest pre-test probabilities based on clinical presentation direct from the literature. References are also easily viewable with a built-in link to Read by QxMD. Lastly, my app also has calculators for common diagnostic prediction rules (Alvarado score, Ottawa Ankle Rule etc.) built right in.
There’s no android version out yet, but I also have the database online at http://www.lrdatabase.com which is mobile friendly. The app is currently on its 10th iteration and has come a long way from Version 1. I am the sole developer so updates come fast and LRs are added continuously as I find them.
I do hope your readers may find my project useful. If you’d like to see some examples of how my app can be useful in practice, I recently wrote for the BoringEM ER blog (http://boringem.org/2015/05/07/how-to-use-likelihood-ratios/) and the CMAJ blog (http://cmajblogs.com/a-tool-to-assist-point-of-care-evidence-based-diagnosis/).

outstanding app idea. The trick will be to help the user get the pre-test probability right. A colleague challenged me to make such an app purely for influenza diagnosis. We all suck at this diagnosis clinically (per the literature, and I humbly admit same for me), yet I puzzle over how to help a clinician evaluate pre-test probability. I’ll give the app a look. Thanks for posting.

great app icon, too, I’ll add!January 2, 2016 at 11:55 am #77908
Thanks for the kind comments! I hope you’ve been finding it useful.December 3, 2016 at 8:05 pm #85039
Update: I have recently released DxLogic for Android too!February 26, 2017 at 5:00 pm #85897
I have recently released version 3 of DxLogic to the app store (earlier release also available in the android store). The app now contains almost ONE THOUSAND diagnostic tests, as well as over FIVE HUNDRED pre-test probabilities.
I have made the app a lot more visual, with pie charts to illustrate probabilities of disease. Finally, I’ve included a Not-To-Miss Diagnoses section listing life-threatening aetiologies for common presentations.
The app is being used by physicians across the world, and was recently featured at Harvard Macy’s Program for Medical Educators.
The database is also available completely free at http://www.lrdatabase.com
Please let me know if you’d like any more information on the app. I hope your and your readers may find it useful.March 30, 2018 at 11:00 pm #88094
The newest iteration of my app (now named docLogica) is much more refined with many new useful features including a searchable database of disease symptoms and DDx Maker.
If this isn’t worth a review, I don’t know what is!
