  • Associate Professor of Medicine
  • Mayo Clinic Rochester

2
Disclosures
  • I am a member of the Boston Scientific Patient
    Safety Advisory Board

  • No off-label use of drugs or devices will be
    discussed

3
Objectives
  • Explain why Osler did the study
  • Explain why certain data were gathered

William Osler
5
Science and Immortality1904 Ingersoll Lecture at
Harvard University
  • Annual lecture on topic of immortality (still
    given today)
  • Osler invited to give lecture multiple times by
    then Harvard President Eliot
  • Osler eventually, yet reluctantly, agreed and
    gave lecture 18 May 1904
  • Later published as a book

6
Science and ImmortalityExcerpt
I have careful records of about five hundred
death-beds...Ninety suffered bodily pain or
distress of one sort or another, eleven showed
mental apprehension, two positive terror, one
expressed spiritual exaltation, one bitter
remorse. The great majority gave no sign one way
or the other like their birth, their death was a
sleep and a forgetting (p.19).
7
Why re-examine OslersStudy of the Act of
Dying?
  • A detailed manuscript describing the study and
    its results was never published, yet the brief
    quote from Science and Immortality continues to
    be cited
  • Analysis would shed light on the attitudes toward
    death and the dying experience and during Oslers
    era
  • Few similar studies have been done

8
Methods of the current analysis
  • Resources
  • Data collection cards and a spreadsheet used by
    Osler and stored at McGill University
  • JHH administrative records
  • Oslers papers
  • Methods
  • Data abstracted from cards and compared to data
    recorded on Oslers spreadsheet

9
Features of Oslers study
  • Done at the Johns Hopkins Hospital (JHH)
    1900-1904
  • Observations of 486 dying patients recorded on
    data collection cards
  • Data from cards transferred to a spreadsheet
    tallied by Osler

Purpose of the study
  • Printed at bottom of data collection card
  • The object of this investigation is to ascertain
    the relative proportion of cases in which (1) the
    death is sudden (2) accompanied by coma or
    unconsciousness (3) by pain, dread, or
    apprehension.

Life on the JHH wards1898 Nursing Annual Report,
Mary A. Nutting
The head nurses are responsible for the general
management of the wardsThey are held responsible
for every detail in connection with their wards,
of which they do not and cannot do the actual
work. They are an essential feature of a
properly organized and equipped ward.

For about 10 minutes before death the patient
was in a condition of acute mania. He fought
with the orderlies, bit one and was restrained
with difficulty.
Oslers spreadsheet also marked none for each
38
What conclusions can be drawn from the study
results?
  • Nurses played a major role in the study Osler
    had little direct involvement
  • Data collected suggest nearly constant bedside
    presence of observers who completed the data
    cards
  • Dying patients were young
  • Median length of illness before death was brief
    shorter for children

39
What conclusions can be drawn from the study
results?
  • Most common cause of death infectious diseases
    causes differed by gender
  • A majority experienced coma before death median
    duration of coma brief
  • More patients (38) experienced discomforts
    (mostly physical) than reported by Osler (21) in
    Science and Immortality

40
What prompted Osler to do a study of
dying?Personal interest
  • 1872 to investigate causes of death among the
    highest objects of the physician
  • Entries in his pocket day books
  • Plans for lectures and essays (eg, On the Hour
    of Death)
  • Numerous volumes on death, dying and related
    topics in his personal library

41
What prompted Osler to do a study of
dying?Popular opinion and fears
  • Death viewed as the King of Terror. Why?
  • Decline of religious faith
  • Reduced death rates, especially due to infectious
    diseases death primarily affects elders with
    chronic diseases
  • Rise of science, and hospitals death medicalized
    and moved from home to hospital
  • Death becomes foreign to most

42
What prompted Osler to do a study of dying?Osler
openly disputed the popular opinion
  • Osler, like many physicians of his era, refuted
    the popular opinion that death was accompanied by
    suffering
  • 1888 article death a sleep and forgetting
  • 1893 lecture death accompanied with pleasure
    rather than with pain
  • Nevertheless, empirical data about death were
    sparse Osler was a naturalist

43
Why were certain data gathered?
  • Popular concerns about apparent death, the
    nature of the exact moment of death and about
    discomforts associated with the dying process
  • Physician interest in modes of death
  • Sudden versus gradual
  • Cardiac versus respiratory
  • Presence or absence of coma

44
Why were the results reported by Osler inaccurate?
  • Possible reasons
  • Osler did not carefully examine data cards (he
    did not sign any of them)
  • Confusing layout of data cards
  • Osler did not complete the spreadsheet
  • Osler inaccurately tallied the spreadsheet
  • Haste

48
Possible role of haste
  • Short interval between last case (29 Mar 1904)
    and lecture (18 May 1904)
  • Hectic time for Osler
  • Very busy with consultative practice and
    scholarly activities
  • Great Baltimore Fire of February 1904 nearly
    consumed Oslers home
  • Observations of others and comments by Osler

Observations of others and comments by Osler
  • Possible role of haste
  • Cushing1 lecture written in a single morning
  • Cushing biography notes2 lecture written in
    some haste...misquoted sources
  • Osler letter to Miss Jewett2 a rash production

51
McCrae on Science and ImmortalityLetter to
Cushing (8 Jul 1920)
There is one point there in which I know you are
in error namely in saying that the address
Science and Immortality was written in a
morning. Up till that time he had never spent as
much time on an address and had written it
several times.
Thomas McCrae
52
Cushing on Science and ImmortalityThe Life of
William Osler (Oxford, 1925)
With all this pressure upon him the date of the
Ingersoll Lecture was approaching, and though he
had been making notes and giving thought to it
during the preceding months there had been scant
time for the sort of preparation the subjectHe,
indeed, had agonized over it perhaps more than
any of his previous drafts and it was rewritten
and redrafted many times. (p. 638)
53
Parts of Science and Immortality were written
years before the lecture
  • Osler traveled to Minneapolis during 1898
  • Document in Cushing folders at McGill
  • Written chiefly in the train from Minneapolis to
    Boston copied Sept. 24th and 25th.
  • Fragment written by W.O. (Script) on 1 West
    Franklin Street notepaper.
  • Contains basic elements of Science and
    Immortality (but no mention of the dying study)

54
Oslers reporting of the study resultsProbable
sequence of events
  • Osler wrote elements of Science and Immortality
    years before it was given
  • Final touches were likely added in haste
  • Hectic period for Osler
  • Study statistics must have been added just prior
    to the lecture
  • Spreadsheet and spreadsheet tally (the statistics
    cited in lecture) were inaccurate
  • Observations of colleagues and Osler suggest haste

55
What were Oslers views of death after the study?
  • Remained interested in the topic and did not
    waver in his opinion as expressed in Science and
    Immortality
  • Added volumes on death and dying to his library
  • 1911 letter to Spectator protests painful
    characterization of death in essay (Death)
    written by Nobel Prize (literature) recipient
    Maeterlinck
  • 1919 wrote book review of Aspects of Death by F.
    Parkes Weber for Ann Med History

56
Oslers death at age 70 years29 Dec 1919
  • Acute complication of chronic bronchitis
  • Experienced painful bouts of coughing
  • Shunt the whole pharmacopoeia, except opiumWhat
    a comfort it has been!
  • Osler calmly accepted death
  • The experience has been encouraging--discomfort
    of course, but no actual pain except for the
    worry about leaving dear ones, singularly free of
    mental distress

57
Conclusions
  • A substantial number of dying patients in Oslers
    study experienced discomforts
  • Osler was prompted to do the study because of
    popular fears and a lack of empirical data
    regarding death
  • The historical context of the study is rich
  • Lessons for today
