TheraDoc's patented Expert System Platform (ESP) collects data from a multitude of sources such as patient location (ADT - Admission, Discharge and Transfer), pharmacy, and laboratory orders and test results, utilizing Oracle's Database Advanced Queuing technology to process patient events. Then TheraDoc's selection of specialized Knowledge Modules uses expert systems to process rules based on best-practice guidelines in several categories. These Knowledge Modules include the Infection Control Assistant, Antibiotic Assistant, Clinical Alerts Assistant, and the ADE Assistant (Adverse Drug Events). Any system that deals with the very sensitive information required for real-time patient care needs a consistently reliable place to store its data. For TheraDoc, Oracle Database was the logical choice.
"When we had to make a decision on the database in the year 2000, selecting Oracle was easy", stated Jonathan Olson, Chief Technology Officer of TheraDoc. "No other database could offer the transaction processing capabilities combined with the simultaneous aggregation that our systems need. Reliability is obviously of paramount importance, and Oracle has a proven track record there also. Finally, there were specific functional areas, like Advanced Queuing, which were only available in Oracle."
Although it is a small company of about 60 employees, TheraDoc's impact is nationwide. The organisations selecting its system support patient care in over 39.000 beds and for millions of in- and out-patient visits in 152 hospitals in 29 states. Some of these health care facility sites include Johns Hopkins Hospital, University of Pittsburgh Medical Center (UPMC), Mayo Clinic-Florida, University of Pennsylvania Health System (UPHS), Nebraska's Great Plains Regional Medical Center, Chicago's Northwestern Memorial Hospital and several hospitals in the VA system. The scale of health care organisations is also vast, ranging from 50 beds to 3500 beds.
"The scalability of Oracle Database means that its performance is the least of our worries", continued Jonathan Olson. "The database will scale smoothly from our smallest system, based on a single processor, to our largest, currently a Unix machine with 10 processors. We can support all of our hospitals with a single Database Administrator, using either the Oracle Database Standard Edition or Enterprise Edition, depending upon the hospital's needs."
TheraDoc has a non-negotiable adherence to medical informatics standards. This is the key to connectivity and interoperability with multiple internal and external information systems, as well as to accurate and immediate delivery of real-time patient information and best-practice knowledge to clinicians.
"Both TheraDoc and Oracle have the same commitment to standards-based software", stated Jonathan Olson. "This makes it much easier to keep our systems up to date as software development and the health care industry evolve. The capabilities within Oracle Database make it easier, faster and cheaper to develop our products, and Oracle's embedded license policy further enables us to make a truly cost-effective proposition to hospitals everywhere in North America."
