There is no reliable registry of medical subspecialists in Chile. Acco
rding to the records of the Autonomous National Corporation for Certif
ication of Medical Specialties (CONACEM), the largest number of certif
ications is in internal medicine (n=681), followed by cardiology (n=15
3), respiratory medicine (n=106), gastroenterology (n=93), endocrinolo
gy (n=77), rheumatology (n=55), hematology (n=50) nephrology (n=50), a
nd infectious diseases (n=31). Over 55% of those certified in internal
medicine and 70% of those certified in medical subspecialties (except
nephrology) live in the metropolitan area of Santiago. Almost 80% of
university-trained internists have received their training at the Univ
ersity of Chile (1952-1995), whereas 52% of university-trained subspec
ialists have been trained at the Catholic University of Chile. A sizea
ble number of nonofficial specialist-training programs are conducted a
t some universities at variance with their own official training polic
ies. In internal medicine, a larger number of specialists have been tr
ained by the universities than are certified by CONACEM, whereas the c
onverse is true for medical subspecialists. More than 80% of the inter
nists in Chile work for the Ministry of Health, who cares for 70% of t
he country's population, The best internist: population ratio is in Ar
ica and Valdivia, and the poorest one in Arauco and in Vina del Mar/Qu
illota. According to estimations done by the Santiago Medical Society
(Chilean Society of Internal Medicine) and its subspecialty affiliate
societies, an adequate proportion of internists would be 1 for every 1
0,000 inhabitants, and for subspecialists, 1 for every 100,000 inhibit
ants. More information is needed about the ideal number of specialists
and subspecialists required, and about their ideal distribution throu
ghout the country. CONACEM needs to be strengthened, the universities
should be able to certify non-university training centers, and the mig
ration of subspecialists out of Santiago should be encouraged.
