San Francisco and Marin counties who received multiple independent recommendations from their peers. The survey process started with
a list of more than 3,000 licensed doctors across all specialties in both counties. All doctors on this list were both candidates and eligible
voters in the peer-to-peer voting poll. Doctors were allowed to cast an unlimited number of votes across all specialties — they could vote
for as many doctors as they wanted regardless of specific area of expertise — but they could only vote for the same doctor once.
Response rate was maximized by the following procedures: (a) a long field period of 12 weeks that was further extended to allow
all doctors ample time to log in and vote for peers; (b) multiple channels of solicitations including both individual invitations and
organizational outreach to maximize contact with all eligible voters; and (c) repeated invitations and reminders to doctors who did not
respond to initial rounds of solicitations. At the close of the voting period, approximately 600 doctors with the highest vote counts were
short-listed for the database. Each of these doctors received a statistically significant number of votes from peers based on established
principles of sampling probabilities and power analysis. LinChiat Chang, Ph.D.
We asked doctors, “Whom would you send your family
members to, or whom would you go to, if faced with a
medical problem?” More than 19,000 votes were cast,
and the results — 605 physicians, all in the 415 area code
— are listed on the following pages. To search by specialty
