The Utilization of Infobuttons at Intermountain Healthcare – An Update In 2010

1. The Utilization of Infobuttons at Intermountain Healthcare – An Update In 2010 Jinqiu Kuang1, Nathan Hulse PhD1,2 , Catherine Staes1, Peter Haug MD1,2 University of Utah1 and Intermountain Healthcare2, Salt Lake City, Utah • Results • The most common medications: From Jan 2002 to Feb 2010, the most frequent medications were mostly antivirals and antidepressants (Table 4). Except that Oseltamivir Phosphate was ranked number one during my study period and peaked in Oct 2009, which corresponded closely with the local outbreak of H1N1 flu in Oct 2009(Fig. 3). • Introduction • In 2001, infobuttons were first implemented at Intermountain Healthcare outpatient electronic medical record system (HELP2).1 • This study aims to describe trends in infobutton utilization over time and provide a baseline for the next generation of infobutton research. Results • Method • Infobutton usage data from Jan. 1st, 2008 to Feb. 28th, 2010 were extracted from the Clinical Knowledge Repository (CKR) monitoring tables, converted to script files, and then imported into the infobutton data mart. • Conclusion • The continuous growth of usage confirms the usefulness of infobutton. • Future research • It would be interesting to find out the factors associated with the frequency of infobutton use. • Further research is necessary to understand how users’ previous learning experiences impact their usage of the system and fundamentally affect the outcome of care. • Introducing next-generation HL7 standard Infobuttons is desirable to improve the infobutton performance. • It would be helpful to investigate the effect of adding new knowledge resources, such as DxPlain, Isabel on infobutton utilization. • Results • Unique users: In 14 months, 5,986 unique users were captured by the system, with an average 1,227 per month (Fig.1). Del Fiol’s study showed only 2,611 users over four- year period. Physicians remained the heaviest users, since 15.5% of all users were physicians who accounted for almost half of all sessions through the study period. • Sessions: the number of sessions recorded has increased over 45% from the count of 5,140 in Jan 2009 to 7,478 in Feb 2010 (Fig. 2). • Clinic modules: Medications continue to be the most common infobutton targets (71%), followed by laboratory results (24%) and problems (3%) (Table 1). • Resources: Micromedex was still dominant (69%), followed by Clineguide (13%) and MDConsult (9%) (Table 2). • Physician specialty: Among the 673 physicians, family practice and internist physicians accounted for 27% and 10% of the entire user group respectively (Table 3).
