Directory report for Q1 2023
Nat Pernick, M.D.
27 April 2023

This is our first quarterly report on pathologists based on our Worldwide Directory of Pathologists. We are initially focusing on pathologists in the U.S. and Canada. We are excluding pathologists who requested inactivation of their profiles or who are deceased.

We currently have 20,169 profiles. For Canada, we believe the directory is > 90% complete. For the U.S., we believe we have profiles for > 90% of academic pathologists but are 3 - 6 months away from being > 90% complete for private pathologists.

We suggest that pathologists review their pathology profile at least annually or when they move institutions. Click to add or revise your profile or use our Name Search to review your profile.

We define academic as an institution with medical students or residents or that is affiliated with a university and has academic titles. Anything else is private, including industry and government institutions.


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 worldwide are

Anatomic	11,460
Clinical	9,429
Cytopathology	3,130
Hematopathology	2,693
Molecular & genetics	2,109
Dermatopathology	1,455
GI / liver	1,566
Veterinary	1,410
Breast	1,031

Note: we are excluding surgical from this list (2,651) because its use does not appear to be consistent.


Ambassadors

We currently have 45 ambassadors who 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.

Future plans, in addition to adding more pathologists, are to add totals by U.S. state and Canadian province; academic versus private; and by trainee, staff or retired.

For the profiles, we will soon be adding pathologist titles, such as Assistant Professor or Medical Director (free text) and U.S. state or Canadian province (if applicable).
