Here are a few startups I found particularly interesting:
Aidin was created for discharge planning professionals to make the process of finding post-acute care for their patients, efficient and easy.
SwiftPayMD is a payment system for physicians to capture and post charges for each day’s services, for quick and correct billing.
Symcat takes BIG DATA (hundreds of thousands of patient records) to estimate what your ailment might be through a series of questions.
Definitely looking forward to Medicine X 2013. See you there!
