Abstract
Objective: To estimate the number of
general practice (GP)-type patients
attending a rural ED and provide
a comparative rural estimate to a met-
ropolitan study.
Methods: Analysis of presentations to
the two EDs in Northwest Tasmania
from 1 January 2009 to 31 Decem-
ber 2013 using the Diagnosis, Sprivulis,
Australian College of Emergency Medi-
cine (ACEM) and the Australian In-
stitute of Health and Welfare (AIHW)
methods to estimate the number of GP-
type presentations.
Results: There were 255 365 ED pres-
entations in Northwest Tasmania
during the study period. There were
86 973 GP-type presentations using the
ACEM method, 142 006 using the
AIHW method, 174 748 using the Di-
agnosis method and 28 922 low acuity
patients identified using the Sprivulis
method.
Conclusions: The proportion of GP-
type presentations identified using the
four methods ranged from 15% to
69%. The results suggest that triage
status and self-referral are not reli-
able indicators of low acuity in this
rural area. In rural areas with a short-
age of GPs, it is likely that many
people appropriately self-refer to ED
because they cannot access a GP. The
results indicate that the ACEM method
might be most useful for identifying
GP-type patients in rural ED. However,
this requires validation in other regions
of Australia.
Key words: emergency department,
general practice-type presentations, low
acuity patients.
Introduction
Worldwide, health systems are grap-
pling with increasing attendances to
EDs.
1
In Australia, attendances at EDs
have increased 17%, in the past 5 years,
to over 6.7 million per year.
2,3
In-
creased attendances at EDs can com-
promise care by increasing wait times
and length of stay; overcrowding has
been shown to contribute to poorer
patient outcomes and, at times, in-
creased patient mortality.
4,5
Emergen-
cy care is also expensive to deliver
compared with other models of care.
6,7
The rate of ED presentations
Australia-wide equates to approxi-
mately 288 per 1000 people. North-
west Tasmania has approximately
51 000 ED presentations per year,
8
a
rate of approximately 451 per 1000
people, which is 1.6 times greater than
the national rate.
Northwest Tasmania has a popula-
tion of 113 000, a fifth of the total
population of Tasmania.
9
The popu-
lation is socioeconomically disadvan-
taged (Australian Bureau of Statistics
Index of Relative Socio-economic
Disadvantage Deciles 1–5)
10
and has
a high prevalence of chronic disease
and lifestyle risk factors.
8
The popu-
lation is geographically dispersed, with
localities classified as Australian Stand-
ard Geographic Classification (ASGC)
Remoteness Area (RA) RA3-outer re-
gional (e.g. Burnie) to RA5-very remote
(e.g. King Island) (RA 3–5).

However,
75% of the population live in the
coastal towns between Devonport and
Wynyard.

Northwest Tasmania has two EDs,

Key findings
• There was wide variation in the
proportion of low acuity and GP-
type presentations estimated by
four different methods.
• 15% to 69% of presentations
were identified as GP-type
patients.
• Methods which rely on triage
status and self-referral may be
less reliable for identifying low
acuity and GP-type patients in
rural EDs.
