If all you want to connect is a reference lab you are in luck. In most cases the reference lab will cover the cost to connect to your EHR.
Simply find the cheapest solution that guarantees interface to your EMR and selected reference lab.
If, on the other hand, you will be operating a lab with one, or more moderately complex devices choosing an LIS will be a whole lot more complex.
The first thing you should do is find a local Lab Consultant to help you make the right choice. It will probably cost you a $1000,
but is likely to save you much more and significantly improve the likelihood that you will still have a lab a year later.
The range in LIS costs for a moderately complex lab with two, or three, lab devices will range from a low of $5,000 to a high of $30,000
and all systems will do what you need done. The $5,000 solution will only do what you need, but should allow you to add functions over time
if you need them. The $30,000 system will have all the features you will ever need (and maybe some you will never need).
Five year cost of ownership can range from a low of $20,000 to a high of $60,000.
Never buy an LIS without having first written down your required work flow. Once you have your work flow defined ask each vendor you are
considering to show you how they deal with each required function. All vendors are happy to provide you with a web-based demo.
Never buy an LIS without having the person who will run the lab see the demo and be absolutely clear on how each function will work.
If an LIS vendor cannot show you how their application performs each step of your required work flow you need to cross them off your list.
Your LIS vendors will be happy to provide as many demos to as many members of staff as you would like.
Don't let your providers tell you they are too busy to check the format of the LIS reports.
Get TEN references and call them. Make a spreadsheet listing all the functions that you know you will need. Ask each vendor to show you how they
handle each function and then grade them (e.g. Poor, OK or Great).
