The voting process for “Top Doctors” is peer-based and national. According to the Philadelphia magazine website, each year Castle Connolly Medical Ltd. sends out tens of thousands of invitation letters to physicians in private practice — randomly selected — as well as to the medical leadership of major medical centers, specialty hospitals, teaching hospitals and regional medical centers. Invited physicians can go online to a special restricted-access website and nominate outstanding physicians in various specialties and subspecialties “to whom you would send members of your family.”
The process asks not only for doctors who excel in academic medicine and research but also for those with outstanding interpersonal skills. The process enables outstanding doctors in the Philadelphia area to be nominated by their peers throughout the country, and not simply by other local doctors.
