Comments
• General Praise– Knowledge link is fantastic. VERY useful.– Great resource!!– I love knowledge link
• Quality of Care– …very helpful with patient-directed questions during the visit– I was able to quickly answer the patient’s question …the patient
had been promptly served on his needs– This info actually saved me from making a medical error…I rarely
use this feature of the LMR, but this time it really helped me
• Convenience– Knowledge Link is a great time saver…handy and easy to use.– I really like having the ability to look up drugs without having to
change screens– I really like having the information available one click away from
the med list– I was very happy to be able to click on the information link as I was
pulling up the prescription– To have info on meds right at my fingertips is a great timesaver– it is very helpful to have all the information right at my finger tips
instead of browsing through multiple book sources

Summary
• Infobuttons are utilized and valued by all types of care providers, not just MDs– Rapid adoption despite lack of training or
introduction– Extremely positive feedback overall
• Infobuttons are effective (84% answer rate)
• Infobuttons can have significant impact on patient care even when used infrequently, but direct measurement of effect is difficult
• A minimal implementation can be both technically simple and clinically effective

HL7 Standard for Infobutton Integration
Guilherme Del Fiol, MD, MSIntermountain Health Care
University of UtahSalt Lake City, UT
![Page 59: Integration of Health Information Resources into Electronic Health Records](https://reader035.fdocuments.us/reader035/viewer/2022062409/568145aa550346895db29fbc/html5/thumbnails/59.jpg)
Why do we need a standard?
• There is not a common integration language– Query parameter names– Terminologies used for content
search retrieval
• Hundreds of resources available– Not designed for infobutton
integration: suboptimal results– Labor intensive integration: just a few
are actually used

Benefits Realized by Users/Institution
• Reduces time/effort to answer key clinical questions - little/no training required
• More care, less searching - used frequently
• Needed knowledge more directly into workflow - affects decisions
• Context/patient-specific information - more responsive to needs
![Page 85: Integration of Health Information Resources into Electronic Health Records](https://reader035.fdocuments.us/reader035/viewer/2022062409/568145aa550346895db29fbc/html5/thumbnails/85.jpg)
Benefits for Institution
• Enhanced care sooner: – Quick/easy integration; hosted data– less training
• Promotes best clinical practices: – Reduce unanswered/un-pursued clinical ?s
and negative care impact – Alters medical/treatment decision 15-20% of
the time*
• Leverages existing subscriptions– Summary/infobutton -> drill down to richer
content
