- Vojtech Huser, MD, PhD Morgridge: Project proposal January 26, 2012 Dear Vojtech, We are looking forward to your presentation at our February 3, 2012 Informatics Grand Rounds at 12:15 p.m. Please allow an hour for your talk and a brief question period. As I am sure you know, there are a number of important administrative things that we need to do in order to comply with CME's very strict regulations. Please be certain to make a verbal disclosure at the start of your presentation as well as including the Disclosure slide at the start of the talk. I would be most grateful if you could return the information and various forms listed below to me by email on or before February 1, 2012. We are now publicizing your talk around the campus. 1. Title of Talk, abstract (have already) 2. Learning Objectives (have already) 3. Your CV or Bio 4. Signed Disclosure Form (attached) 5. Signed Webcast Permission Form (attached) 6. Copies of your disclosure & objectives slides (see attached, please edit as you wish) 7. Speaker Information Sheet (attached) -JHU's CME office requires that a disclosure and objectives slide be part of your presentation. Please visit: http://www.hopkinscme.net/Resources/RSCSupport.aspx , for examples. If you have any questions or concerns about this Webcasting/archiving, please let us know. Previous recordings are posted at http://dhsi.med.jhmi.edu/content/past_seminars.cfm For more information regarding requirements visit: http://dhsi.med.jhmi.edu/content/speakers.html You may send these documents via email. For driving directions visit: http://dhsi.med.jhmi.edu/content/visitors.html I know that Harold has already sent you the objectives of the DHSI Seminar Series, but have listed them again below for you to reference while filling out these forms. OBJECTIVES FOR THE SERIES: 1. Evaluate the ongoing development of the National Health Information Network 2. Identify key components of health information technology in a variety of health care and public health settings 3. Critique the success of health information technology through evaluation studies 4. Assess fit between information architecture in complex health settings and health needs 5. Characterize success of information technologies in technology-poor settings 6. Evaluate decision support in a variety of health-care related settings Thank you very much for participating in our seminar, and especially for doing the extra paper work required by CME.

- Vojtech Huser, MD, PhD Morgridge: Project proposal Linear regression (LR) was used to determine whether score difference could be predicted by any of the participant characteristics such as gender, age, SQL experience, or SQL experience source. No LR model could predict the score difference (adjusted R-squared < 0.1) and none of the factors were statistically significant. A two-sample t-test showed no statistical difference in test score differences between the group which started with SQL approach versus the group which started with RG approach. TRANSITION: In a way the quantitative part served as a preparation for the later qualitative questionnaire part Giving the users an active experience with both compared technology – do you want to be facing flowcharts or SQL code There was a suggestion to conduct just the qualitative part, Since there are some design limitations of the task-based quantitative study – which, in fact, do not play such role in the qualitative study. So in a way I consider the qualitative study of higher importance
