I think it needs to be a compelling service from a financial perspective in order to get the hospital's legal and financial departments to approve. If we were able to move 10-15 patients per day to a partner hospital, it could be adding $1 million/yr in profit to the hospital, easily. Hence the need for volume before we can partner with more hospitals.
Thanks for the comments.
So I'd go looking for a hospital that has a lot of these folks that use their ER and see if you can't set up a partnership based on the work you are currently doing with this hospital. Better yet, get a list of 50 such hospitals and work your way down :) With a high-enough density target market, you can move to things like radio, doorhangers, or newspaper ads. The interesting question is whether or not to use SEO, because of the geographical limitations.
Neat idea. I was just talking with a guy a couple of weeks ago about this exact thing, except for doctor's offices.
I wonder about scaling past that first hospital, though. Kind of a catch-22 situation -- the hospital has to be small enough to not care about having part of its records online yet large enough to support a growing business.
