1. Using web-based quality data to choose a primary care physician: which information do patients rely on most? Gary Fanjiang, Ted von Glahn, Hong Chang, William H. Rogers, Dana Gelb-Safran Funding provided by RWJF and AHRQ

2. Background Despite growing demand, quality of care indicators are often ignored. Patients are most interested in data to inform their physician choice but few data are available.

3. Study Aims To examine if patients seeking a new PCP make use of web-based physician specific information. To evaluate which types of information users find most important.

4. The Website Information on physician credentials and characteristics, office location and hours, and patient survey scores. Patient survey scores from the Ambulatory Care Experiences Survey (ACES).

5. Patient Survey Scores (ACES) Five summary measures: –Appointment access –Interpersonal quality –Coordination of care –Health promotion –Willingness to recommend the physician

7. Study Sample 2225 adult patients seeking a new PCP at two California medical groups were invited by mail. 17 percent viewed the website (n=382). 80 percent of those viewing the site completed a follow-up questionnaire (n=306).

11. Limitations Limited to only 2 medical groups. Information priorities may be different in people who do not use the internet. Unknown if participants formalized their physician choice.

12. Conclusions One in six patients seeking a new physician logged-on and used the web- based data to inform their choice. High participation rates suggest the value of “just-in-time” information.

13. Conclusions Of the different types of information, patient survey results were widely regarded as a priority. Of the survey results, interpersonal quality and willingness to recommend the physician were valued most. Choice of physician was highly concordant with patients’ stated priorities – suggesting users are capable of using web-based information to inform their choice appropriately.

14. Conclusions The results underscore the value of developing a national standard for measuring patients’ experiences with individual physicians and their practices.
