Assessment

Perhaps Osler's greatest influence on medicine was to insist that students learn from seeing and talking to patients and the establishment of the
medical residency Residency or postgraduate training is a stage of graduate medical education. It refers to a qualified physician (one who holds the degree of MD, DO, MBBS/MBChB), veterinarian ( DVM/VMD, BVSc/BVMS), dentist ( DDS or DMD), podiatrist ( DPM), o ...
. The latter idea spread across the English-speaking world and remains in place today in most teaching hospitals. Through this system, physicians in training make up much of a teaching hospital's medical staff. The success of his residency system depended, in large part, on its pyramidal structure with many interns, fewer assistant residents and a single chief resident, who originally occupied that position for years. While at Hopkins, Osler established the full-time, sleep-in residency system whereby staff physicians lived in the administration building of the hospital. As established, the residency was open-ended, and long tenure was the rule. Physicians spent as long as seven or eight years as residents, during which time they led a restricted, almost

life. He wrote in an essay, "Books and Men", that "He who studies medicine without books sails an uncharted sea, but he who studies medicine without patients does not go to sea at all." His best-known saying was "Listen to your patient—he is telling you the diagnosis", which emphasises the importance of taking a good history. The contribution to medical education of which he was proudest was his idea of clinical clerkship – having third- and fourth-year students work with patients on the wards. He pioneered the practice of bedside teaching, making rounds with a handful of students, demonstrating what one student referred to as his method of "incomparably thorough physical examination." Soon after arriving in Baltimore, Osler insisted that his medical students attend at bedside early in their training. By their third year they were taking patient histories, performing physicals and doing lab tests examining secretions, blood and excreta. He reduced the role of

In Britain he was the first (and only) president of the Medical Library Association of Great Britain and Ireland and also a president of the Bibliographical Society of London (1913). Osler was a prolific author and public speaker and his public speaking and writing were both done in a clear, lucid style. His most famous work, '' The Principles and Practice of Medicine'' quickly became a key text to students and clinicians alike. It continued to be published in many editions until 2001 and was translated into many languages. It is notable in part for supporting the use of

as the "author of the most famous medical textbook ever written". He noted that Avicenna's '' Canon of Medicine'' remained "a medical bible for a longer time than any other work". Osler's essays were important guides to physicians. The title of his most famous essay, "''Aequanimitas''", espousing the importance of imperturbability, is the motto on the Osler family crest and is used on the Osler housestaff tie and scarf at Hopkins.


Controversies


Racism

Osler said Canada should be a "white man's country" in a 1914 speech given around the time of the

involving immigration from India. Osler wrote "I hate Latin Americans" in a letter to Henry Vining Ogden. Under the pseudonym "Egerton Yorrick Davis", Osler mocked Indigenous people: "Every primitive tribe retains some vile animal habit not yet eliminated in the upward march of the race." Uncovering this historical context, the journalists David Bruser and Markus Grill and the archivist Nils Seethaler reconstruct the shipment of several indigenous skulls by Osler from Canada to Germany, which were (previously unknown) in the custody of the State Museums of Berlin.


Gerontology
