This is our quarterly report on pathologists based on our Worldwide Directory of Pathologists. It provides information of interest to pathologists that is not available anywhere else, to our knowledge. We are initially focusing on pathologists in the U.S. and Canada. We are excluding pathologists who requested the inactivation of their profiles.Totals are as of 31 December 2023, unless otherwise indicated.

The quality of this data will improve as more pathologists review and update their profiles. Pathologists, please review your pathology profile this month, when you move institutions and at least annually. Review this month because we need you to populate these new fields: Title (text), Status (trainee, staff or retired), Year of birth, Gender identity (male, female, other, blank) and Personal pronouns. The Year of birth and Gender identity will only be used for summary totals in this report; individual responses will not be posted anywhere or made available to anyone.
Please click to add or revise your profile (make sure birth year, gender, position and pronouns are completed) or use our Name Search to review your profile.

We added 1,627 profiles in Q4 of 2023 for a total of 25,721 pathologist profiles completed as of 31 December 2023. For the U.S., we added 1,530 profiles for a total of 22,036. For Canada, we added 35 profiles for a total of 2,211. We believe the Directory is > 90% complete for U.S. academic pathologists and all pathologists in Canada.

Specialties and subspecialties

We prefer pathologists to only list specialties or subspecialties in which they received specific training or have a particular interest. Pathologists that review almost all specimens should list anatomic or clinical pathology. Most pathologists should list at most 3 - 4 options.

To date, the top specialties or subspecialties listed in our worldwide profile directory are

Anatomic	16,307
Clinical	13,979
Cytopathology	4,273
Hematopathology	3,544
Surgical	3,286
Molecular & genetics	2,471
Dermatopathology	2,201
GI / liver	1,813

Note: we are excluding surgical from this list (3,105) because its use does not appear to be consistent.


Ambassadors

As of 22 February 2024, we have ambassadors for 57 institutions / regions. Ambassadors help ensure that the Directory includes all practicing pathologists for their group (unless they opt out), tell us when pathologists come and go and otherwise assist in making the Directory as accurate as possible. More information about being an ambassador is here. If interested, please contact Amal@PathologyOutlines.com.
