Outpatient
non-attendance
is
a
common
source
of
inefficiency
in
a
health
service,
wasting
time
and
resources
and
potentially
lengthening
waiting
lists.
A
prospective
audit
of
plastic
surgery
outpatient
clinics
was
conducted
during
the
six
months
from
January
to
June
1997,
to
determine
the
clinical
and
demographic
profile
of
non-attenders.
Of
6095
appointments
16%
were
not
kept.
Using
the
demographic
information,
we
changed
our
follow-up
guidelines
to
reflect
risk
factors
for
multiple
non-attendances,
and
a
self-referral
clinic
was
introduced
to
replace
routine
follow-up
for
high
risk
non-attenders.
After
these
changes,
a
second
audit
in
the
same
six
months
of
1998
revealed
a
non-attendance
rate
of
11%
-i.e.
30%
lower
than
before.
Many
follow-up
appointments
are
sent
inappropriately
to
patients
who
do
not
want
further
attention.
This
study,
indicating
how
risk
factor
analysis
can
identify
a
group
of
patients
who
are
unlikely
to
attend
again
after
one
missed
appointment,
may
be
a
useful
model
for
the
reduction
of
outpatient
non-attendance
in
other
specialties.
INTRODUCTION
In
1984
it
was
estimated
that
of
35.5
million
National
Health
Service
(NHS)
outpatient
appointments
booked,
5
million
were
broken1
at
a
cost
of
up
to
£266
million.
More
recent
Department
of
Health
figures
indicate that
as
much
as
£360
million
is
now
wasted
each
year2.
6
million
appointments,
at
an
average
cost
of
£61
each,
were
missed
in
1996-1997,
accounting
for
12%
of
all
appointments
made.
In
addition
156000
patients
(4.6%)
did
not
turn
up
for
scheduled
operations.
Non-attendance
at
outpatient
clinics
is
thus
not
only
wasteful
of
resources
but
may
also
increase
patient
morbidity
and
lengthen
waiting
lists,
extending
the
waiting
time
for
an
outpatient
appointment
from
between
one
week
to
up
to
six
months3.
The
main
reasons
for
patient
non-
attendance
are
often
specialty
non-specific,
and
include
simply
forgetting,
illness,
work
commitments
and
transport
difficulties-1
8.
The
time
interval
from
referral
to
the
appointment
date
also
seems
to
influence
attendance,
with
those
patients
receiving
appointments
beyond
two
months19
or
within
one
week6
of
referral
least
likely
to
attend.
Despite
attempts
to
reduce
non-attendance
rates
by
raising
public
awareness
(Figure
1)
and
by
specifically
addressing
these
various
causal
factors,
non-attendance
remains
persistently
troublesome
throughout
the
NHS.
Telephone
and
postal
reminders
can
help13'20
but
may
not
be
cost-effective
if
up
to
60%
of
unkept
appointments
remain
unkept8.
More
convincing
successes
have
been
gained
by
restoring
the
responsibility
for
making
new
appointments

OF
THE
ROYAL

to
the
patients
themselves.
When
provided
with
a
freephone
telephone
number
by
one
hospital,
88%
of
new
gynaecology
referral
patients
arranged
their
own
appointments,
of
which
only
2.5%
were
missed21.
Another
promising
strategy
has
been
recently
piloted
whereby
patients
are
provided
with
a
copy
of
their
referral
letter22.
In
one
general
practice
this
reduced
the
non-attendance
rate
for
referrals
from
6%
to
zero.
It
seems,
therefore,
that
compensating
for
non-
attendances
by
overbooking,
rather
than
by
trying
to
reduce
non-attendance
rates,
can
no
longer
be
considered
conducive
to
the
efficient
running
of
an
outpatient
service.
Here
we
report
a
study
of
the
factors
relevant
to
attendance
and
non-
attendance
by
plastic
surgery
outpatients.
PATIENTS
AND
METHOD
176
outpatient
clinics
were
audited
during
the
study
period
from
1
January
1997
to
30
June
1997.
Most
of
these
were
at
the
Royal
Devon
and
Exeter
Hospital,
although
peripheral
clinics
were
also
held
at
Axminster,
Barnstaple,
Taunton,
and
Torbay
hospitals.
Only
one
clinic
per
week
was
regularly
conducted
by
a
registrar
alone,
while
all
others
were
attended
by
one
of
three
consultants.
At
the
completion
of
each
clinic,
the
notes
for
those
patients
who
did
not
attend
were
examined
by
the
registrar
or
the
consultant,
and
an
audit
questionnaire
was
completed
in
each
case.
For
new
patients,
this
questionnaire
recorded
the
source
of
the
referral
(general
practitioner
[GP],
another
consultant,
accident
and
emergency
department),
the
provisional
diagnosis
and
the
triage
category
(urgent,
soon,
routine).
For
follow-up
patients,
treatment
already
received
(if
any)
and
the
time
since
operation
were
noted.
For
all
patients,
the
number
of
consecutive
non-attenders
(N-As),
the
decision
to
send
a
further
appointment
or
to
discharge,
and
whether
or
not
the
patient's
GP
was
informed
of
their
non-attendance,
were
recorded.
An
anonymous
questionnaire
was
also
sent
to
the
patient,
along
with
an
explanatory
letter
and
freepost
return
envelope.
This
questionnaire
requested
the
age,
sex
and
occupation
of
the
patient
and,
by
listing
several
possible
reasons
for
missing
appointments,
asked
patients
to
account
for
their
non-attendance.
Reasons
not
covered
by
our
list
could
be
specified
in
the
'other'
category.
Lastly,
patients
were
asked
to
describe
briefly
what
treatment
they
had
already
received,
whether
they
were
happy
with
their
care
overall,
whether
they
felt
their
problem
to
have
resolved,
and
whether
or
not
they
were
back
at
work.
RESULTS-PART
I
Doctor
questionnaire
Of
the
6095
appointments
booked
into
the
176
clinics
held
during
the
six
month
period,
892
were
missed
by
731
patients,
an
overall
N-A
rate
of
15%,
equivalent
to
about
5
appointments
per
clinic.
New
referrals
had
a
slightly
lower
N-A
rate
(1
3%)
than
follow-up
appointments
(15%).
The
highest
number
of
N-As,
197,
was
recorded
during
the
first
month
of
the
study,
while
the
average
monthly
figure
was
149.
Of
the
new
referrals
(24%),
who
comprised
a
quarter
of
the
trial,
85%
of
N-As
were
referred
by
their
GP,
the
remainder
being
consultant
and
casualty
referrals.
61%
of
new
referrals
were
triaged
as
'routine'
while
19%
were
deemed
'urgent'
and
20%
needed
to
be
seen
'soon'.
According
to
the
British
Association
of
Plastic
Surgeons
system,
the
main
group
of
missed
appointments
were
hand
trauma
(23%),
followed
by
excision
of
benign
skin
lesions
(14%),
basal
cell
or
squamous
cell
carcinomas
(10%)
and
melanomas
(5%)
(Figure
2).
62%
of
the
appointments
were
missed
in
the
year
after
surgery.
A
first
N-A
was
recorded
536
times,
a
second
consecutive
N-A
219
times,
a
third
105
times,
a
fourth
18
times
and
a
fifth
8
times
(for
6
patients
the
data
were
unavailable).
Hence
some
patients
missed
appointments
more
than
once
within
the
study
period.
596
patients
failed
to
attend
once
during
the
study
period,
1
10
patients
missed
two
consecutive
appointments,
and
24
patients
missed
three
consecutive
appointments.
Only
one
patient
missed
four
consecutive
appointments
during
the
audit.

The
decision
to
send
a
further
appointment
after
non-
attendance
broadly
reflected
the
number
of
consecutive
appointments
missed
(Figure
3).
After
one
missed
appoint-
ment,
95%
of
patients
were
sent
another
appointment.
After
two
consecutive
N-As
this
fell
to
64%
and
after
three,
21%.
Only
6%
of
patients
were
sent
for
again
after
four
consecutive
N-As;
after
five,
all
patients
were
discharged.
Correspondence
with
patients'
GPs
largely
correlated
with
discharge
rates.
Patient
questionnaire
731
patients
received
a
questionnaire
during
the
course
of
the
study
and
250
of
these
were
returned,
a
response
rate
of
34%
(male:
female
ratio
I
1
.04).
65%
of
patients
were
among
the
working
population
but
27%
were
retired.
The
reasons
for
non-attendance
could
be
broadly
divided
into
those
attributable
to
hospital
factors
(41%)
and
those
determined
by
the
patient
(59%)
(Figure
4).
Of
the
latter,
35%
simply
forgot,
14%
had
work-related
reasons,
10%
were
ill,
and
10%
could
not
get
transport
to
the
hospital.
However,
a
substantial
proportion
of
patients,
16%,
gave
reasons
about
which
the
hospital
could
have
done
nothing,
such
as
poor
weather
making
the
journey
difficult.
Hospital
factors
were
blamed
by
41%
of
respondents
for
their
non-attendance,
including
a
failure
of
the
hospital
to
inform
them
of
their
appointment
(40%)
and
the
appointment
having
been
formally
cancelled
in
advance
by
either
the
patient
(33%)
or
the
hospital
(10%).
At
the
time
of
completing
the
questionnaire,
94%
of
respondents
were
happy
with
their
care
overall,
61%
felt
that
their
problem
was
already
resolved
and
75%
had
returned
to
work.
Statistical
analysis
The
aim
of
the
first
audit
was
to
identify
factors
which
might
influence
a
patient's
likelihood
of
not
attending.
Several
trends
may
be
observed
in
the
above
results,
but
two
factors
only
were
found
significant.
By
means
of
x2
analysis,
comparison
of
appointments
missed
for
a
first
time
with
serially
missed
appointments
(multiple
N-As)
identified
predictors
of
multiple
non-attendance
as
(1)
coding
for
hand
trauma
(relative
risk
1.4,
P
<0.01)
and
(2)
after
one
missed
appointment,
time
since
surgery
greater
than
three
months
(relative
risk
1.9,
P<0.01).
After
one
'hand
trauma'
N-A,
the
chance
of
a
subsequent
appointment
being
missed
was
50%.
Similarly,
after
one
N-A,
the
risk
of
a
further
N-A
within
three
months
of
surgery
was
calculated
at
26%,
rising
to
49%
after
three
months.
INTERVENTION
As
a
result
of
this
audit,
areas
of
inefficiency
became
apparent.
Our
follow-up
guidelines
were
amended
to
ensure
that
wherever
there
may
be
an
element
of
concern
(such
as
treatment
for
skin
cancers,
congenital
malforma-
tions,
or
complex
hand
trauma),

further
appointment,
perhaps
even
after
several
N-As.
Otherwise
all
patients
were
discharged
after
two
non-
attendances.
However,
on
the
basis
of
the
risk
factor
analysis
for
multiple
N-As,
those
patients
non-attending
for
the
first
time,
if
beyond
3
months
from
a
minor
procedure
(such
as
excision
of
a
benign
skin
lesion)
or
if
originally
treated
for
a
minor
hand
injury,
were
either
discharged
or
sent
details
of
a
new
'self-referral'
clinic
essentially
the
existing
registrar
clinic
to
which
patients
could
directly
gain
access.
This
empowered
patients
to
telephone
for
a
further
appointment
if
they
so
desired,
thereby
returning
responsibility
for
care,
where
appropriate,
to
the
patient.
Second
audit
Changes
to
our
follow-up
guidelines,
and
the
new
self-
referral
clinic,
were
introduced
in
October
1997.
Three
months
later,
a
second
audit
was
begun
to
assess
the
impact
of
these
changes
during
an
equivalent
time
period
from
January
to
June
1998.
During
this
period,
however,
only
clinics
at
the
Royal
Devon
and
Exeter
Hospital
were
audited
(120
in
total).
Information
regarding
the
number
of
patients
who
did
not
keep
appointments,
the
number
to
whom
self-
referral
advice
letters
were
sent,
and
the
number
requesting
self-referral
clinic
appointments
was
collected
prospec-
tively.
RESULTS-PART
2
During
the
second
audit,
7135
appointments
were
booked
of
which
787
were
missed.
This
N-A
rate,
at
11%,
was
30%
lower
than
that
in
the
main
hospital
for
the
equivalent
period
of
1997
(16%).
107
self-referral
clinic
advice
letters
were
sent
to
patients
who
did
not
attend
outpatients
for
a
first
time
who
met
the
criteria
established
by
our
unit
follow-up
guidelines
(1.1
per
clinic
on
average).
Only
2
of
these
107
patients
asked
to
be
seen
again.
DISCUSSION
NHS
Executive
data
for
1996-1997
identified
94
000
missed
appointments
in
plastic
surgery
clinics
in
England
alone,
with
a
mean
national
N-A
rate
within
the
specialty
of
around
16%
(Table
1)23.
The
N-A
rate
for
the
Royal
Devon
and
Exeter
Healthcare
NHS
Trust
during
the
1997
audit
was
also
16%,
while
our
overall
N-A
rate,
including
peripheral
clinics,
was
15%.
This
compares
favourably
with
non-
attendance
rates
recorded
by
other
specialties10-'4'17'2425.
A
sizeable
increase
in
the
number
of
appointments
booked
at
the
main
hospital
in
the
second
year
raises
a
question
whether
like
is
being
compared
with
like.
Part
of
the
explanation
may
be
an
increase
in
the
activity
of
the
self-
referral
clinic.
There
was
no
obvious
change
in
the
nature
of
the
population
attending
outpatient
clinics
in
the
second
year.
The
main
reasons
for
non-attendance-namely,
forget-
ting,
illness,
work
commitments,
transport
and
adminis-
trative
problems
on
the
part
of
the
hospital-were
similar
to
those
reported
previously"'4.
Of
the
administrative
failures,
common
errors
were
failure
of
notification
and
cancellation.
The
large
number
of
missed
appointments
relating
to
hand
trauma
and
excision
of
benign
skin
lesions
during
the
six
month
period
was
in
proportion
to
the
overall
case
mix
in
the
unit.
Nevertheless,
unnecessarily
booked
appoint-
ments
are
often
missed
because
the
patient
believes
the
problem
to
have
resolved.
Additionally,
some
follow-up
patients
may
be
long-term
attenders,
with
chronic
disorders
changing
little
from
one
appointment
to
another.
They
may
account
for
high
N-A
rates
among
certain
other
patient
groups,
such
as
melanoma
review
patients.
The
number
of
N-As
prevented
by
changes
to
our
follow-
up
guidelines
may
be
estimated
by
comparison
of
rates
before
and
after
intervention.
On
this
basis,
we
would
have
expected
1141
patients
not
to
keep
appointments
during
the
second
audit,
whereas
only
787
did
so;
thus
354
potentially
wasted
appointments
were
avoided.
Furthermore,
the
near-
zero
uptake
of
self-referral
clinic
appointments
validates
exclusion
of
this
targeted
patient
group
(n
=
107)
from
further
follow-up
in
main
outpatient
clinics.
Clearly
there
is
a
massive
financial
incentive
to
reducing
high
numbers
of
missed
appointments.
In
our
study,
the
cost
of
354
missed
appointments
(if
each
one
is
valued
at
£612)
equates
to
over
£20
000.
