UVM College of Medicine

In 2001 Luann Rolley of the UVM College of Medicine contacted RIS with a problem. The database she used to maintain critical data about the HIV+ patients seen by the 4 clinics around Vermont was getting too expensive. "...we had a beautiful, but very complex database system that required many hours of programmer time to update...The costs associated with these changes became prohibitive."

Luann had taken a database design class taught by RIS founder Carl Lorentson and knew there had to be a better way, and she was right. Tom Cooley, with RIS since 1998, worked with her to create a new database application that would respond to changes in the patient care world. "Federal requirements and new advances in the care of HIV+ patients necessitate frequent modifications to our database."

In December, 2003 the clinics changed the way they collected and organized lab results. Unfortunately the database was not configured to record information in a manner consistent with their new procedures. She called RIS and in just 15 minutes we had walked her through the process of developing a new questionnaire to collect the lab results separately from patient visits saving her hundreds if not thousands of dollars over the previous database.

This success story is just one of the many instances where the flexibility of a solution from RIS has paid for itself.
