The epidemiology of acute rheumatic fever in Northland, 2002-2011.
[acute rheumatic fever]
An
audit
of
rheumatic
fever
surveillance
in
Northland
was
carried
out
for
the
period
2002
-
2011
.
The
aim
of
the
audit
was
to
establish
the
accuracy
and
completeness
of
surveillance
of
Acute
Rheumatic
Fever
in
Northland
,
and
to
provide
a
robust
baseline
for
future
comparison
given
current
rheumatic
fever
prevention
efforts
.
Cases
of
acute
rheumatic
fever
(
2002
-
2011
)
were
identified
and
evaluated
through
auditing
Northland
hospital
discharges
,
the
Northland
Rheumatic
Fever
secondary
penicillin
prophylaxis
register
and
the
national
EpiSurv
database
.
Cases
were
included
in
the
audit
if
they
met
diagnostic
criteria
according
to
the
2008
Heart
Foundation
guidelines
.
A
total
of
114
acute
rheumatic
fever
cases
met
the
audit
criteria
,
an
annualised
incidence
of
7
.
7
/
100
,
000
in
Northland
.
95
%
of
all
cases
were
Maori
with
a
large
disparity
between
Maori
(
24
.
8
/
100
,
000
)
and
non-
Maori
(
0
.
6
/
100
,
000
)
.
Acute
rheumatic
fever
cases
were
strongly
associated
with
living
in
high
deprivation
areas
.
This
audit
noted
both
under-
and
over-notification
of
acute
rheumatic
fever
.
Acute
rheumatic
fever
rates
in
Northland
Maori
children
aged
5
-
14
(
78
/
100000
)
are
similar
to
those
seen
in
developing
countries
and
nearly
double
the
rates
seen
other
New
Zealand
audits
.
The
findings
highlight
the
urgent
need
to
address
crowding
,
poverty
and
inequitable
primary
care
access
if
rheumatic
fever
is
to
be
eliminated
.
