Sir,
The last HIMSS conference which took place in Orlando Florida last week would have provided significant opportunities to assess whether the market satisfies identified needs/wants.
Please review the posted presentations as well as the guide of exhibitors, it might lead you to some integrated solutions based on open standards ...if you find what you are looking for shop for Open source and Open standrads apps, they are both easier to integrate and replace when something more up-to-date comes to be.
This year's exhibites were significantly more mature than a year ago.
