Comments

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

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

HL7 Standard for Infobutton Integration

Guilherme Del Fiol, MD, MSIntermountain Health CareUniversity of UtahSalt Lake City, UT


Why do we need a standard

Why do we need a standard?

  • There is not a common integration language

    • Query parameter names

    • Terminologies used for content searchretrieval

  • Hundreds of resources available

    • Not designed for infobutton integration: suboptimal results

    • Labor intensive integration: just a few are actually used
