Project Title:  Wireless, Pen-Based Front-End to Cancer Knowledge Sources.
Related Award(s):  N44-CO-40550
Technology Developed:
Although considerable effort has been put into creating extensive on-line reference resources for oncology, this compiled knowledge has been underutilized in clinical situations. This SBIR project was designed as a step to remedying this deficiency, basically by combining Lexical’s Oncology Knowledge Authority (OKA), a component for retrieving relevant information from machine-readable knowledge sources, with Stanford’s Mobile Access to Oncology Knowledge (MATOK), a pen-based interface.

Key Words:  oncology, machine-readable, pen-based interface, on-line reference.
Uses of Technology/Products/Service:
Two deployments of MATOK were carried out during Phase II, at the NIH Clinical Center’s Pediatric Oncology Clinic (in April 1996) and at the Stanford Oncology Day Care Clinic (in July 1996). The OKA and MATOK were installed and placed into use at the NIH Clinical Center at the end of March 1996, using wireless interfaces. The MATOK client was tested and revised extensively, the OKA Access Protocol was modified and extended to handle the scaled-up database and needs of the clinical environment, and the AllTel TDS 7000 system was integrated with MATOK. The server system was installed in the Clinical Center’s machine room, and wireless access points were installed in the Pediatric Oncology Clinic and in the in-patient unit. The four tablet computers were assigned and the initial groups of users were trained on the system. Regular joint meetings between Lexical and Stanford project team members were held to conduct further tests on and to streamline the evaluation of the pen system. Nightly reports testing the OKA showed that both the OKA machine and its Illustra database were stable and continued to work unattended. Very few bugs were reported by users. During 1994-1996, results of this SBIR were disseminated by project participants to the following organizations and audiences: American Medical Informatics Association (AMIA) symposium (Washington, D.C.); Symposium on Computer Applications in Medical Care (SCAMC); ANSI Healthcare Informatics Standards Planning Panel (Crystal City, Virginia); ARPA Domain Specific Software Architecture Healthcare Meeting (John Silva, M.D., Chairman); American College of Physicians; Lippincott & Co. (medical publisher); NIH Clinical Center; Illustra; Medical Library Association (annual meeting); International Medical Informatics Association Working Group (Geneva, Switzerland); Healthcare Information and Management Systems (HIMSS) conferences (Phoenix, Arizona, and San Antonio, Texas); Medinfo’95 conference (Vancouver, Canada); National Cancer Institute; and the Artificial Intelligence in Medicine spring symposium. Fourteen publications resulted from this work.
