Two phone apps that use Bayes to help doctors make better decisions [links]
Bayes at the Bedside and Rx-Bayes come with databases of likelihood ratios and help doctors estimate probabilities from their phones. I met somebody at Singularity Summit 2011 who used one of them, but I can’t remember which.
SymCAT is another piece of software that appears* to use Bayesian methods to suggest possible diagnoses (it has a mobile app for Android).
*they don’t actually mention “Bayes” (or give much detail at all) in any of the descriptions I can find, but they talk about machine learning and “frequency and likelihood”, as well as giving giving the probability of each possible diagnosis given the symptoms.
