HISTORY
OF
INFORMED
CONSENT
Informed
consent
for
surgical
procedures
is
a
relatively
new
trend
in
the
practice
of
surgery.
For
thousands
of
years
physicians
felt-that
deception
was
an
integral
part
of
the
practice
of
medicine.
Over
the
last
150
years,
the
con-
cept
of
physicians
establishing
a
"standard
of
care"
has
gradually
been
replaced
by
the
idea
that
the
well-
informed
patient
can
be
the
master
of
his/her
own
body.
Thus,
the
practice
of
informed
consent
has
emerged
as
surgery
has
become
more
patient-oriented.
EARLY
HISTORY
In
ancient
Greece
patient
participation
in
decision
mak-
ing
for
medical
treatment
was
considered
undesirable.
It
was
generally
accepted
that
the
physician's
primary
task
was
to
inspire
the
confidence
of
the
patient
in
the
treat-
ment.
Any
disclosure
of
possible
difficulties
might
erode
patient
trust.
Later,
during
medieval
times,
medical
writ-
ing
encouraged
doctors
to
use
their
conversations
with
patients
as
an
opportunity
to
offer
comfort
and
hope
while
emphasizing
the
need
for
the
doctor
to
be
manipulative
and
deceitful.
To
effect
a
treatment
cure,
it
was
widely
felt
that
authority
must
be
coupled
with
obedience.9
During
the
Era
of
Enlightenment,
new
views
emerged
stating
that
patients
had
the
capacity
to
listen
to
the
doc-
tor,
but
it
was
still
felt
that
deception
was
necessary
to
facilitate
patient
care.
During
the
1800's
the
medical
pro-
fession
was
split
over
whether
to
disclose
a
dire
prognosis
to
a
patient.
However,
most
physicians
of
the
time
argued
against
informing
patients
of
their
condition.9
The
doctrine
of
assault
and
battery
has
its
roots
in
early
English
Common
Law.
This
Doctrine
forms
the
basis
for
the
possible
"injury"
or
"liability"
incurred
from
surgery
without
proper
consent.3
Common
Law
is
the
combination
of
customs,
traditions,
and
case
law;
it
is
distinct
from
legislative
law
which
is
law
enacted
by
a
governing
body.7
Many
of
these
English
Common
Law
doctrines
have
influ-
enced
our
tort
system
of
justice.
Assault
is
a
threat
by
one
person
to
do
bodily
harm
to
another
while
battery
is
the
actual
touching
of
a
person
by
another.
Therefore,
the
the-
ory
of
tort
battery
became
the
unauthorized
touching
of
a
person
by
another.3
As
the
concept
of
informed
consent
gained
popularity
during
the
twentieth
century,
the
courts
extended
the
English
Common
Law
Tort
doctrine
of
negligence
to
the
field
of
surgery
by
equating
negligence
with
breach
of
duty
and
breach
of
duty
with
an
incomplete
patient
con-
sent.
Currently,
the
failure
of
a
physician
to
provide
ade-
quate
information
to
the
patient
about
his/her
own
treat-
ment
is
interpreted
by
the
courts
as
a
breach
of
duty
by
the
physician.3'9
With
this
early
background,
let
us
turn
in
chronological
order
to
some
of
the
more
significant
legal
cases
of
the
twentieth
century
and
then
examine
how
these
cases
have
shaped
the
current
doctrine
of
informed
consent.
Luka
v.
Lowrie,
136
N.W.
1106,
Michigan
1912
In
this
case,
a
surgeon
believed
that
an
emergency
amputation
was
necessary
to
save
a
child
who
had
sus-
tained
a
crush
injury
to
his
foot.
Before
proceeding
with
procedure
the
surgeon
consulted
four
other
physicians,
all
of
whom
agreed
that
an
emergency
amputation
of
the
child's
foot
was
necessary.
The
child's
parents
were
unavailable
to
discuss
the
matter.
Subsequently,
the
court
ruled
that
if
they
had
been
available,
the
parents
would
have
agreed
with
the
need
for
an
emergency
amputation
when
informed
that
multiple
physicians
had
been
con-
sulted,
all
of
whom
agreed
with
the
need
of
an
emergency
procedure.
Schoendorff
v.
Society
of
New
York
Hospital,
211
N.Y.
215,105
N.E.
92,1914
This
case
has
had
probably
the
most
impact
on
the
doctrine
of
informed
consent,
and
first
established
that
the
patient
was
an
active
participant
in
the
treatment
deci-
sion
process.
In
this
case,
Justice
Benjamin
Cardozo
summarized
"every
human
being
of
adult
years
in
sound
mind
has
a
right
to
determine
what
shall
be
done
with
his
own
body;
and
a
surgeon
who
performs
an
operation
without
his
patients
consent
commits
a
battery
for
which
he
is
liable
in
damages".
Dicenzo
v.
Berg,
16
A2d
15,
Pennsylvania,
1940
In
this
case,
the
court
supported
the
defendant's
(the
physician)
attempt
to
supply
the
patient
with
a
description
of
the
procedure
to
be
performed
even
though
the
plaintiff
(the
patient)
was
not
pleased
with
the
outcome.
The
104
The
Iowa
Orthopaedic
Journal
The
History
of
Informed
Consent
patient
had
originally
consented
to
a
surgical
procedure
on
his
neck
but
was
quite
concerned
about
scarring
the
exposed
portion
of
his
neck.
After
the
surgery,
the
patient
felt
that
the
surgeon's
incision
and
subsequent
scar
were
inappropriate,
and
subsequently
brought
suit.
The
court
eventually
ruled
that
the
surgeon
must
be
given
sufficient
latitude
within
the
boundaries
of
the
patient's
consent
to
operate.
The
court
determined
that
the
surgeon
had
obtained
adequate
consent
from
the
patient
and
had
placed
the
incision
appropriately
and
therefore
should
not
be
liable.
Prince
v.
Massachusetts,
321
US
158,
1944
Early
in
this
century,
the
courts
established
a
concept
that
has
remained:
parents
cannot
refuse
treatment
to
their
children
on
the
basis
of
religious
beliefs.
In
this
case
the
Supreme
Court
stated
"Parents
may
be
free
to
become
martyrs
themselves,
but
it
does
not
follow
that
they
are
free,
in
identical
circumstances,
to
make
martyrs
of
their
children
before
they
have
reached
the
age
of
full
and
legal
discretion
when
they
can
make
that
choice
for
themselves."
Two
examples
are
members
of
the
Jehovah's
Witness
Church
denying
medically-necessary
blood
transfusions
to
their
children
and
Fundamentalist
Chris-
tians
in
southern
West
Virginia
requiring
children
to
han-
dle
snakes
during
worship
services
and
refusing
them
medical
attention
once
bitten.
In
both
of
these
situations
the
parents
would
be
subject
to
child
neglect
laws.
Bang
v.
Charles
T.
Miller
Hospital,
251
Minn,
427.88
N.W.
2d
186,
Minnesota,
1955
This
case
established
that
the
patient
was
entitled
to
know
inevitable
risks
or
results
of
surgery.
In
this
case
an
elderly
male
patient
consented
to
a
transurethral
prosta-
tectomy.
He
was
not
specifically
informed
prior
to
the
pro-
cedure
that
the
accepted
surgical
technique
would
in
all
likelihood
leave
him
sterile
post-operatively.
The
surgeons
in
this
case
were
found
liable.
Corn
v.
French,
71
Nev.
280,289
P.
2d
173,
Nevada,
1955
Corn
v.
French
established
that
the
surgeon
must
not
misrepresent
the
surgery
to
be
performed.
In
this
case,
after
examining
the
patient,
the
physician
advised
that
she
undergo
a
test
for
a
possible
malignancy
of
the
breast.
The
patient
subsequently
asked
the
doctor
if
he
intended
to
remove
her
breast,
to
which
the
physician
replied
"no".
The
patient
then
signed
a
written
form
consenting
to
a
"mastectomy"
even
though
she
received
no
explanation
of
the
procedure.
Inevitably,
the
physician
was
found
liable
for
an
unauthorized
procedure.
Natanson
v.
Kline,
350
P2d
1093,
Kansas,
1960
In
this
case
the
court
found
that
the
patient,
not
the
sur-
geon,
must
be
the
final
decision
maker.
The
final
sum-
mary
read:
'A
man
is
the
master
of
his
own
body
and
he
may
expressively
prohibit
the
performance
of
life-saving
surgery
or
other
treatment."
A
doctor
may
believe
that
an
operation or
other
form
of
treatment
is
desirable
or
neces-
sary,
but
the
law
does
not
permit
him
to
substitute
his
own
judgement
for
that
of
the
patient
by
any
form
of
misrepre-
sentation
or
deception.
Darrah
v.
Kite,
32
A2d
108,
New
York,
1969
The
verdict
in
this
case
established
that
each
invasive
diagnostic
test
requires
a
separate
consent.
This
lawsuit
resulted
when
the
parents
consented
to
having
their
child
admitted
to
the
hospital
for
"routine"
brain
tests
in
order
rule
out
a
developmental
disorder.
The
physician
then
pro-
ceeded
with
a
complete
workup
including
invasive
tests.
Ultimately,
the
court
ruled
against
the
physician
finding
that
"routine"
brain
tests
did
not
include
significant
inva-
sive
studies
and
established
that
patients
should
not
be
admitted
to
a
hospital
under
a
general
consent
of
admis-
sion
and
then
receive
a
wide
variety
of
invasive
diagnostic
tests
without
separate
specific
consents.
Green
Case,
296
A.2d
681,
Pennsylvania,
1971
In
this
case
the
court
authorized
blood
transfusions
for
a
Jehovah's
Witness
child
with
paralytic
scoliosis.
This
patient
had
a
940
curve
with
pulmonary
and
cardiac
impairment.
The
mother
consented
to
a
spinal
fusion,
but
refused
to
consent
to
any
blood
transfusions.
The
court
ruled
that
without
the
scoliosis
surgery
(and
the
incum-
bent
blood
transfusions)
the
patient
would
be
considered
under
state
law
a
neglected
child
because
he
did
not
receive
the
surgery
required
for
his
well-being.
Subse-
quently,
a
court-
appointed
guardian
authorized
the
scolio-
sis
surgery
and
subsequent
blood
transfusions.
In
re
Osborne,
294
A2d
372,
Washington,
D.C.,
1972
The
courts
have
traditionally
held
that
if
a
patient
with
dependents
refuses
a
blood
transfusion
necessary
to
save
his
or
her
own
life,
the
transfusion
can
be
given.
In
this
situation
an
individual's
religious
freedom
can
be
super-
seded
by
the
right
of
society
to
reduce
the
number
of
peo-
ple
on
welfare
and
attempt
to
preserve
the
family
unit.
Over
time,
however,
the
courts
have
developed
limitations
to
these
restrictions
based
mainly
on
the
doctrine
of
informed
consent.
An
example
of
this
is
the
Osborne
case
where
a
thirty-four-year-old
married
man
with
two
chil-
dren
was
severely
injured
when
struck
by
a
tree.
The
patient
refused
to
accept
blood
tr_nsfusions
on
the
basis
Volume
10
105
PM
Murray
of
religious
beliefs.
The
patient
was
deemed
fully
compe-
tent
and
expressed
the
desire
to
obtain
"everlasting
life"
rather
than
receive
a
blood
transfusion.
Subsequently
the
courts
found
that
his
wife
was
competent
to
run
the
family
business
and
provide
for
the
children.
Additionally,
if
the
wife
was
unsuccessful
in
managing
the
family
business,
then
the
wife's
parents
and
brother
affirmed
that
they
would
care
for
the
children
if
necessary.
The
court
then
could
find
no
obvious
interest
to
society
in
restricting
this
patient's
religious
freedom,
and
so
a
blood
transfusion
was
not
ordered.
Cobbs
v.
Grant,
502
P2d
1
California,
1972
Prior
to
this
ruling,
courts
in
most
states
had
upheld
the
prevailing
"standard
of
practice"
rule
with
respect
to
risk
disclosure.
The
decision
in
this
case
posed
the
more
lib-
eral
patient-oriented
concept
of
the
disclosure
of
risks:
"Had
the
patient,
judged
as
a
reasonable
and
pru-
dent
person,
been
provided
adequate
information
about
the
procedure
and
its
risks
prior
to
consenting
to
the
procedure,
or
if
some
material
risk
had
been
presented,
would
the
patient
have
refused
to
proceed
with
surgery?"
In
this
case
the
plaintiff
(patient)
underwent
surgery
for
a
duodenal
ulcer
and
an
artery
at
the
base
of
the
spleen
was
lacerated
resulting
in
splenectomy.
The
patient
had
not
been
informed
that
injuries
to
the
spleen
occur
in
approximately
5%
of
duodenal
ulcer
repairs.
Subse-
quently
the
patient
sued
for
malpractice
at
time
of
surgery
and
for
negligence
on
the
part
of
the
physician
for
failure
to
obtain
a
complete
informed
consent.
The
jury
returned
a
verdict
in
favor
of
the
plaintiff
and
assessed
damages
against
the
hospital
and
the
surgeon.
Canterbury
v.
Spence,
464
F2d
772,
Washington,
D.C.,
1972
The
courts
have
generally
affirmed
that
rare
risks
of
surgery
do
not
need
to
be
specifically
discussed
as
part
of
the
consent
unless
these
rare
risks
pose
critical
conse-
quences.
In
this
case
Mr.
Canterbury
sought
medical
treatment
for
back
pain
from
an
neurosurgeon,
Dr.
Spence.
Dr.
Spence
performed
a
myelogram
which
dem-
onstrated
a
filling
defect
at
the
T4
level
consistent
with
a
herniated
thoracic
disc.
Dr.
Spence
then
proceeded
to
rec-
ommend
the
laminectomy
which
was
performed.
Preoper-
atively
Dr.
Spence
did
not
provide
a
thorough
description
of
the
procedure
and
did
not
indicate
that
paralysis
was
a
known
complication
to
the
procedure.
Additionally,
he
did
not
indicate
any
alternative
methods
of
treatment
to
Mr.
Canterbury.
Mr.
Canterbury
underwent
an
uneventful
laminectomy
and
did
well
post-operatively
until
he
fell
from
bed
incurring
a
T4
complete
paraplegia.
In
the
law-
suit
that
followed
the
court
held
that
Dr.
Spence
had
been
negligent
in
obtaining
a
complete
consent.
The
court
also
stated
that
in
consenting
a
patient
the
following
must
be
included
in
order
to
assure
that
the
patient
has
adequate
knowledge
of
the
procedure,
the
diagnosis
and
differential
diagnosis,
required
diagnostic
procedures,
detailed
description
of
the
surgical
procedure
with
any
postopera-
tive
treatment
necessary,
the
risks
of
the
surgical
proce-
dure,
any
alternative
methods
of
treatment,
and
expected
results.
Richardson,
284
So.2d
195
Louisiana,
1973
The
courts
had
established
that
when
parents
grant
consent
for
children
the
procedure
to
be
performed
must
have
some
specific
benefit
for
the
patient.
In
the
Richard-
son
case
a
child
developed
renal
failure
requiring
renal
transplantation.
A
second
child
in
the
Richardson
family
who
was
mentally
retarded
was
deemed
a
renal
transplan-
tation
candidate
to
the
first
child.
The
court
later
ruled
that
the
parents
could
not
authorize
the
mentally
retarded
child
to
become
a
renal
transplantation
donor
because
there
was
no
specific
derived
benefit
to
the
mentally
retarded
child.
Reif
v.
Weinberger,
372
F.Supp.
1196,
District
Court
Washington,
D.C.,
1974
This
case
established
that
any
consent
given
under
physical
or
mental
duress
is
invalid.
In
this
case
tubal
liga-
tion
was
recommended
to
a
patient
on
welfare.
The
patient
was
also
advised
that
if
she
did
not
have
the
tubal
ligation,
her
welfare
benefits
would
be
significantly
reduced.
The
District
Court
of
Washington,
D.C.
deter-
mined
that
this
was
consent
given
under
duress
and
not
a
voluntary
consent.
The
consent
was
therefore
deemed
invalid
and
the
surgeon
was
found
liable
for
assault
and
battery.
In
re
Melideo,
390
N.Y.S.
2d
523,
New
York,
1976
In
the
Melideo
case,
Mrs.
Melideo
received
a
dilatation
and
curettage
of
the
uterus
for
diagnostic
purposes.
After
surgery,
she
developed
significant
bleeding.
Mrs.
Melideo
refused
blood
transfusions
on
the
basis
of
her
religious
belief
against
blood
transfusions.
Subsequently
a
court
order
was
sought
by
the
hospital
in
an
attempt
to
autho-
rize
a
transfusion
against
the
expressed
desires
of
the
patient.
The
court
determined
that
a
patient
may
decline
treatment
and
that
to
order
such
a
treatment
that
is
expressively
refused
by
the
patient
on
religious
grounds
would
be
a
violation
of
that
patients
constitutional
protec-
tion
of
religious
freedom.
Subsequently,
the
transfusion
was
not
ordered.
Robert
Quachenbush,
383
A2d
785,
New
Jersey,
1978
This
case
illustrates
that
medically
necessary
treat-
ment
other
than
blood
transfusions
can
be
refused
for
rea-
sons
other
than
religious
reasons.
Additionally,
this
case
106
The
Iowa
Orthopaedic
journal
The
History
of
Informed
Consent
points
out
that
a
patient's
refusal
of
medically
necessary
treatment
does
not
determine
competence
in
treatment
decisions.
Robert

was
an

His
tem-
perature
was
elevated
and
cultures
were
positive
for
clos-
tridium.
The
patient's
lower
extremities
were
black
and
drained
purulent
fluid;
however,
the
use
of
IV
antibiotics
produced
a
temperature
defervescence.
The
patient's
phy-
sician
recommended
bilateral
above
the
knee
amputations
on
an
emergent
basis.
Mr.
Quachenbush,
however,
stated
that
he
had
objected
to
most
medical
care
for
over
forty
years
and
subsequently
refused
the
recommended
surgi-
cal
debridements
and
amputations.
The
surgeon
believed
that
Mr.
Quachenbush
was
suffering
from
organic
brain
syndrome
and
presented
the
situation
to
hospital
adminis-
trators.
The
hospital
in
turn
petitioned
the
court
to
have
a
guardian
appointed
to
make
medical
decisions
for
Mr.
Quachenbush,
who
was
felt
to
be
incompetent
to
make
treatment
decisions
because
of
his
organic
brain
syndrome.
The
court,
however,
found
that
refusal
for
above
the
knee
amputations
interfered
with
the
accepted
medical
treatment
for
his
condition.
Mr.
Quachenbush
did
have
an
understanding
of
the
proposed
procedure
with
his
risk
in
expectations.
The
court
felt
that
Mr.
Quachenbush
had
a
valid
concern
about
the
risks
and
subsequent
rehabilita-
tion
after
bilateral
above
the
knee
amputations.
There-
fore,
the
court
found
the
patient
to
be
competent
to
decide
on
surgical
alternatives
and
ruled
that
the
amputations
could
not
be
required
based
on
the
right
to
privacy
under
Federal
Constitutional
Law.
Bech
v.
Lovell,
362
So.2d
802
Louisiana,
1978
The
State
Court
ruled
that
a
spouse
or
family
member
cannot
consent
for
surgery
in
place
of
the
competent
patient.
The
only
exception
to
this
situation
would
be
the
added
presence
of
a
medical
emergency
where
the
other-
wise
competent
patient
might
be
unable
to
participate
in
the
consenting
process.
A
family
member's
consent
for
an
otherwise
competent
patient
who
had
been
sedated
would
therefore
be
inadequate.
A
second
situation
that
could
arise
is
the
physician
obtaining
consent
from
a
family
member
because
the
unavailability
of
the
patient;
such
a
consent
would
be
considered
inadequate
based
on
this
ruling.
Truman
v.
Thomas,
27
Cal.3d
285,
California,
1980
Although
the
patient
has
a
right
to
refuse
tests
or
treat-
ment,
the
courts
have
established
that
the
physician
has
a
duty
to
inform
patients
of
the
risks
of
refusal.
In
Truman
v.
Thomas,
the
patient
rejected
a
family
doctor's
advice
to
have
a
pap
smear.
Subsequently,
on
repeated
occasions
the
family
doctor
recommend
a
complete
physical
exami-
nation
including
a
pap
smear.
The
patient
refused
each
of
these
pap
smears
and
the
physician
assumed
that
the
patient
knew
the
purpose
of
the
test
and
did
not
specially
discuss
with
her
the
risks
of
failing
to
have
the
pap
smear.
Eventually,
the
patient
developed
advanced
cervical
can-
cer.
In
the
lawsuit
that
followed,
the
California
Supreme
Court
overturned
a
lower
court
ruling
and
stated
that
the
physician
had
the
duty
to
disclose
all
information
to
patients,
including
the
possible
outcome
of
refusing
rec-
ommended
screening
tests
for
cancer.
Perna
v
Pirozz,
92
N.J.
446,457
A.2d
431,
New
Jersey,
1983
Surgery
performed
by
a
person
other
than
the
surgeon
named
by
the
patient
at
the
time
of
consent
constitutes
battery.
Additionally,
the
originally
authorized
surgeon
who
obtained
the
consent
but
failed
to
perform
the
surgi-
cal
procedure
is
therefore
liable
for
malpractice
on
the
basis
of
breech
of
duty.
Precourt
v.
Frederich,
395
689,481
N.E.2d
1144
Massachusetts,
1985
The
decision
handed
down
in
this
case
set
limitations
upon
a
physician's
duty
of
risk
of
disclosure
at
the
time
of
consent
and
could
be
interpreted
as
a
"Tort
Reform"
case.
In
this
case
a
patient
underwent
a
surgical
proce-
dure
on
the
eye
for
which
prednisone
was
given
post-
operatively
to
control
inflammation.
Subsequently,
the
patient
developed
aseptic
necrosis
of
both
hips
and
a
law-
suit
resulted.
Even
though
the
Physician
Desk
Reference
(PDR)
lists
aseptic
necrosis
of
the
hips
as
a
complication
from
prednisone
therapy,
a
witness
for
the
defense
testi-
fied
that
a
library
search
of
articles
on
the
subject
showed
no
reports
of
aseptic
necrosis
of
the
hips
developing
sec-
ondary
to
the
postoperative
use
of
prednisone
after
eye
surgery.
Therefore,
a
higher
court
overturned
a
lower
court's
jury
verdict
in
favor
of
the
plaintiff
stating
"in
this
case
there
was
no
evidence
of
the
likelihood
that
a
person
would
develop
aseptic
necrosis
after
taking
prednisone
or
that
Dr.
Frederich
knew
or
should
of
known
that
the
likeli-
hood
was
other
than
negligible.
Large
v.
Superior
Court
of
Arizona,
714
P.2d
399,1986
This
case
demonstrates
that
competence
for
consenting
to
surgical
procedures
may
differ
significantly
from
the
competence
necessary
to
execute
other
activities.
In
Large
v.
Superior
Court
of
Arizona
a
women
with
organic
brain
syndrome
and
poor
cognitive
function
was
admitted
to
the
hospital
with
a
hip
fracture
subsequent
to
a
fall.
The
risks
and
expected
outcome
of
surgical
repair
for
hip
fracture
was
discussed
with
the
patient
by
the
operating
Volume
10
107
PM
Murray
surgeon.
At
that
time
the
patient
was
felt
to
understand
the
material
presented
and
subsequently
consented
to
the
procedure.
At
the
same
time
she
executed
a
will
in
the
presence
of
a
lawyer.
Postoperatively,
the
patient
died
and
both
the
consent
to
surgery
and
her
stated
will
were
reviewed
by
the
court.
The
court
found
that
the
will
was
invalid
due
to
her
lack
of
testamentary
competence
(the
patient
did
not
know
the
extent
of
her
property
or
her
fam-
ily
members).
However,
the
surgical
consent
was
consid-
ered
valid
by
the
court
because
the
patient
was
able
to
understand
the
procedure,
its
risks,
and
potential
benefits.
Younts
v.
St.
Francis
Hospital,
469
P2d
338
(1986)
In
many
states
adolescents
over
fourteen
years
of
age
are
considered
adults
with
the
right
of
privacy,
confiden-
tiality
and
competency
to
consent
to
surgical
procedures.
In
Younts
v.
St.
Francis
Hospital
a
seventeen
year
old
girl
presented
with
a
distal
phalanx
tuft
fracture
and
skin
avulsion
after
trapping
the
finger
in
a
car
door.
The
girl's
mother
was
under
general
anesthesia
at
the
time
of
her
injury
and
her
father
(divorced
from
the
mother)
could
not
be
located.
After
several
attempts
to
locate
the
father
the
procedure
to
be
performed
was
explained
to
the
patient
along
with
its
risks,
benefits,
and
alternatives.
She
subse-
quently
consented
to
the
procedure
but
a
lawsuit
followed.
Ultimately,
the
court
held
that
the
patient,
even
though
she
was
a
minor,
understood
the
nature
of
the
surgery,
possible
risks,
and
potential
benefits.
Therefore,
the
con-
sent
was
found
to
be
valid.
With
the
above
case
decisions
in
mind,
some
conclu-
sions
about
the
doctrine
of
informed
consent
can
be
drawn.
Whenever
a
physician
obtains
a
consent
from
a
patient,
that
physician
should
be
mindful
of
the
conditions
necessary
for
informed
consent,
the
information
require-
ments
necessary
for
an
informed
consent,
patient
compe-
tence
in
delivering
his/her
own
consent
and
how
consents
in
an
emergency
situations
may
be
obtained.
CONSIDERATIONS
FOR
VALID
CONSENT
As
viewed
by
the
courts,
a
consent
is
the
authorization
by
a
patient
to
have
a
certain
medical
treatment
or
sur-
gery
performed
on
that
person.
A
consent
may
be
expressed
or
implied.
An
expressed
consent
is
one
that
is
either
written
or
spoken
by
the
patient.
An
implied
con-
sent
is
one
demonstrated
by
the
acts
of
a
patient.
An
example
of
an
implied
consent
might
be
the
presence
of
a
patient
in
an
examining
room
of
a
doctor's
office.
Although
this
patient
has
not
formally
said
or
written
that
he
or
she
consents
to
a
physical
examination
by
a
physi-
cian,
he
or
she
is
present
on
his
or
her
own
free
will
and
offers
no
resistance
to
examination.
Therefore,
a
complete
consent
form
is
not
a
legal
paper
but
merely
a
documenta-
tion
of
the
patient's
expressed
desires
for
medical
or
surgi-
cal
treatment.
For
a
consent
to
be
valid
it
must
be
obtained
from
a
knowledgeable
patient
who
understands
the
procedure
to
be
performed,
as
well
as
that
procedures
risks,
complica-
tions,
and
possible
alternatives.
Additionally,
the
consent
must
be
voluntarily
given
and
not
received
under
duress
or
threat.
Most
importantly,
the
consent
must
be
given
by
a
patient
who
is
deemed
competent
to
offer
a
medical
consent.3
INFORMATION
NECESSARY
FOR
A
CONSENT
In
Canterbury
v.
Spence
464
F2d
772
Washington,
D.C.
1972,
the
court
held
that
the
consent
must
address
six
different
information
requirements
for
the
patient
to
be
truly
informed.
1)
The
patient
must
be
aware
of
the
diag-
nosis.
2)
The
patient
must
be
aware
of
any
diagnostic
pro-
cedures
necessary
to
ascertain
the
diagnosis.
3)
The
sur-
gical
procedure
must
be
described
in
a
way
that
the
patient
understands.
4)
The
patient
must
be
informed
of
any
inevitable
risks
from
surgery
(frequent
outcomes
of
surgery)
and
any
collateral
risks
(any
complication
arising
indirectly
as
a
result
of
surgery).
5)
The
patient
must
be
informed
all
alternative
methods
of
treatment
both
surgi-
cal
and
conservative,
and
6)
the
expected
results
and
their
probability
should
be
discussed
in
sufficient
detail
with
the
patient
prior
to
surgery.
CONSENTING
COMPETENCE
For
a
patient
to
consent
to
a
surgical
procedure
or
a
medical
treatment
he
or
she
must
be
deemed
competent
from
a
medical
point
of
view
which,
as
pointed
out
earlier,
may
differ
significantly
from
a
legal
point
of
view
(Large
v.
Superior
Court
of
Arizona,
714
P2d
399,
1986).
The
patient
is
considered
medically
competent
and
able
to
give
consent
when
that
person
understands
the
procedure
to
be
performed,
appreciates
the
reason
for
the
proposed
procedure,
and
is
aware
of
the
risks
of
the
procedure
and
the
expected
outcome.
If
the
patient
is
considered
incom-
petent
to
give
a
consent,
the
consent
may
be
obtained
from
the
next
of
kin
(mother,
father,
wife,
sibling,
or
child)
or
the
statute
of
parens
patriae
may
be
evoked
by
the
courts.
A
statute
of
parens
patriae
allows
the
court
to
appoint
a
guardian
for
a
patient
for
the
purposes
of
medi-
cal
decision
making.
Historically,
children
have
not
been
considered
incom-
petent
to
make
medical
decisions;
however,
in
some
states
adolescents
fourteen
years
or
older
are
considered
adults
for
medical
consent
purposes.
Exceptions
to
the
historical
trend,
however,
include:
1)
children
or
adolescents
who
are
pregnant,
2)
children
or
adolescents
who
are
parents,
3)
children
or
adolescents
deemed
self-reliant
in
that
they

EMERGENCY
CONSENT
There
are
certain
exceptions
to
the
previously
men-
tioned
criteria
for
a
valid
informed
consent.
Such
excep-
tions
exist
for
emergency
consenting.
In
this
situation
the
physician
may
proceed
with
treatment
without
formal
con-
sent
from
the
patient.
This
exception
to
the
formal
con-
sent
process
was
created
based
on
the
understanding
that
the
patient,
if
able,
would
consent
for
the
proposed
proce-
dure.
However,
frequently
certain
situations
arise
where
severely
injured
patients
cannot
give
consent
and
family
members
are
unavailable.
In
these
situations,
treatment
frequently
cannot
be
delayed
and
it
must
be
assumed
by
the
physician
that
the
patient
or
the
family
would
provide
authorization
for
the
proposed
treatment
given
the
urgency
of
the
situation.
It
is
generally
felt
that
for
the
physician
to
proceed
in
an
emergency
situation
without
consent
the
following
must
exist:
1)
a
true
medical
emer-
gency,
2)
the
physician
is
truly
unable
to
obtain
consent
from
the
patient
or
next
of
kin,
3)
the
proposed
treatment
is
for
the
ultimate
benefit
of
the
patient.2
CONCLUSION
The
doctrine
of
informed
consent
is
a
relatively
new
idea
in
the
history
of
medical
practice.
The
ancient
practi-
tioners
of
medicine
adopted
a
paternalistic
attitude
towards
patient
care,
and
seldom
involved
the
patient
in
the
decision-making
process.
In
the
18th
and
19th
centu-
ries,
the
concept
of
assault
and
battery
arose
from
English
Common
Law
and
established
the
idea
that
the
surgeon
must
receive
authorization
from
a
patient
before
perform-
ing
surgery
or
otherwise
be
liable
for
breach
of
duty.
Dur-
ing
the
20th
century,
various
legal
decisions
have
gradu-
ally
swung
the
pendulum
from
a
paternalistic,
"standard
of
care"
decision
making
approach
to
a
more
patient-
centered
concept:
"a
man
is
the
master
of
his
own
body...
",
(Natan-
son
v.
Kline,
350
P2d
1093,
Kansas,
1960).
A
valid
consent,
then,
represents
the
evolutionary
pro-
cess
from
paternalistic
medicine
to
patient-centered
medi-
cine.
The
consent
must
be
given
voluntarily
by
a
compe-
tent,
knowledgeable
patient
who
understands
the
proposed
treatments
with
their
incumbent
risks
and
alternatives.
