Use, Usability, Usefulness and Impact of an Infobutton Manager James J. Cimino, M.D. Department of Biomedical Informatics Columbia University College of Physicians and Surgeons 2006 AMIA Fall Symposium

Evaluating the Infobutton Manager What are Infobuttons? What is the Infobutton Manager? How do we study it (modalities)? What did we learn? –How is it used? –How usable is it? –How useful is it? –What is its impact?

Evaluation Log file analysis On-line survey Popup questionnaires survey Log file analysis: 32 months of data

Results: System Log Files March 2004-October 2006: –IM: 3,009 users, 29,541 times

Infobutton Manager (IM) Usage

Resource Use by Context Laboratory Results Review Inpatient Drug Order Review Microbiology Sensitivity Results Diagnosis List Inpatient Lab Order Entry Inpatient Drug Order Entry Health Resources Infobutton Manager

Results: System Log Files March October 2006: –IM: 3,009 users, 29,541 times October 2006: – IM: 281 users, 1,022 times (33/day) – HR: 708 users, 5,744 times (185/day) –HR: 3,609 users, 155,718 times

Resource Use by Context - October

Finding a Resource or Question Users chose questions 48.7% of the time Diagnosis list: % Outpatient drug order review: % Inpatient drug order review: % Users chose at least one resource from HR page 92.4% of the time ( %, depending on user type and context)

Evaluation Log file analysis On-line survey Popup questionnaires survey Log file analysis: 32 months of data On-line survey: 108 comments

Results: On-line Feedback 108 questions or topics submitted by users –54 (50%) in Laboratory Results Review context 30 were about test interpretation –22 (20%) in Inpatient Drug Order Review 15 were about side effects, dosage, cost, trade names, and interactions

Evaluation Log file analysis: 32 months of data On-line survey: 108 comments Popup questionnaires: survey Popup questionnaires: 195/~3,642 (5.4%) survey: 73/1,228 (5.8%)

Survey Responses Q2: Infobuttons are easy to use Q3: Presence of question on the list Q4: Speed of answer Q5: Helpful answer Q6: Positive effect on patient care decisions 1 (strongly positive) to 5 (strongly negative)

Results: Pop-Up and Surveys Pop-Up Easy to use 83% 92% Question on list >50% of time 89% Answered question 69% Useful 77% Helpful >50% of time 90% Positive effect on care 74% Specific cases of improved care 14 (40% of negative responses due to Lab Manual) (Students were the least positive)

Summary of Impact Over 29,000 additional accesses to resources (19%) Positive impact at least half the time: 74% 14 respondents identified one or more specific situations in which patient care improved

Lessons Learned Use of the IM has been more gradual than desired User fails to select a question half the time –Is the IM failing to anticipate the information need? –Example - questions sugested during lab review: Housestaff did not select a question 57.8% of time Online survey: 4/11 dealt with reference ranges IM almost always provides a link to lab manual –Is the user unable to find questions on the IM page? Solutions: –Education –Add questions –User interface

Conclusions 1.Context-specific access to health knowledge resources has been successfully accomplished 2.Impact on patient care decisions has been positive 3.Need to improve user interface for navigation 4.Increased resource use should result in clinicians making better informed patient care decisions
