Aim:
Many
healthcare
providers
rely
on
visual
perception
to
guide
cardiopulmonary
resuscitation
(CPR),
but
little
is
known
about
the
accuracy
of
provider
perceptions
of
CPR
quality.
We
aimed
to
describe
the
difference
between
perceived
versus
measured
CPR
quality,
and
to
determine
the
impact
of
provider
role,
real-time
visual
CPR
feedback
and
Just-in-Time
(JIT)
CPR
training
on
provider
perceptions.
Methods:
We
conducted
secondary
analyses
of
data
collected
from
a
prospective,
multicenter,
randomized
trial
of
324
healthcare
providers
who
participated
in
a
simulated
cardiac
arrest
scenario
between
July
2012
and
April
2014.
Participants
were
randomized
to
one
of
four
permutations
of:
JIT
CPR
training
and
real-time
visual
CPR
feedback.
We
calculated
the
difference
between
perceived
and
measured
quality
of
CPR
and
reported
the
proportion
of
subjects
accurately
estimating
the
quality
of
CPR
within
each
study
arm. Results:
Participants
overestimated
achieving
adequate
chest
compression
depth
(mean
difference
range:
16.1–60.6%)
and
rate
(range:
0.2–51%),
and
underestimated
chest
compression
fraction
(0.2–2.9%)
across
all
arms.
Compared
to
no
intervention,
the
use
of
real-time
feedback
and
JIT
CPR
training
(alone
or
in
combination)
improved
perception
of
depth
(p
<
0.001).
Accurate
estimation
of
CPR
quality
was
poor
for
chest
compression
depth
(0–13%),
rate
(5–46%)
and
chest
compression
fraction
(60–63%).
Perception
of
depth
is
more
accurate
in
CPR
providers
versus
team
leaders
(27.8%
vs.
7.4%;
p
=
0.043)
when
using
real-time
feedback
