10 Australian Refined Diagnosis
Related Groups for admitted
patients
Introduction
Australian Refined Diagnosis Related Groups (AR-DRGs) is an Australian admitted
patient classification system which provides a clinically meaningful way of relating the
number and type of patients treated in a hospital (that is, its casemix) to the resources
required by the hospital. The classification categorises acute admitted patient episodes of
care into groups with similar conditions and similar usage of hospital resources, using
information in the hospital morbidity record such as the diagnoses, procedures and
demographic characteristics of the patient. This report uses AR-DRG version 4.1
(Department of Health and Aged Care 1998).
The AR-DRG classification is partly hierarchical, with 23 Major Diagnostic Categories
(MDCs) into which the 661 AR-DRGs can be grouped. The MDCs are mostly defined by
body system or disease type, and correspond with particular medical specialities.
In general, episodes are assigned to MDCs on the basis of the principal diagnosis. Some
episodes involving procedures that are particularly resource intensive can also be assigned
to the Pre-MDC category (AR-DRGs A01Z–A41Z), irrespective of the MDC assigned on
the basis of principal diagnosis. Records for these episodes have been categorised
separately in tables and figures based on MDCs in this chapter. Episodes with Error-DRGs
(AR-DRGs 901Z–903Z, 961Z–963Z and 960Z, see Glossary) have been similarly
categorised separately, even if they were assigned to an MDC.
Episodes are assigned to AR-DRGs within MDCs, primarily on the basis of the procedure
codes (in the surgical partition) or the diagnosis codes (in the medical partition). When
more than one AR-DRG is associated with a cluster of closely-related procedures or
diagnoses, other variables, such as the patient’s age, complicating diagnoses/procedures
and/or patient clinical complexity level, and the mode of separation, are used for AR-DRG
assignment.
The data were regrouped by the Institute, in consultation with the States and Territories,
and the AR-DRGs that resulted from this regrouping are reported here. They may differ
from AR-DRGs derived at the State or Territory level because of differences in coding and
mapping conventions.
The information in this chapter is presented using both levels of the AR-DRG classification:
•
MDCs—these 23 groups are used to provide information aggregated at a high level
(Figures 10.2 and 10.3, Tables 10.1 to 10.6);
•
AR-DRGs—detailed information is presented for the 30 of the 661 AR-DRGs with the
highest number of separations (Tables 10.7 to 10.16).
All tables in this chapter include separations for which the type of episode of care was
reported as Acute, Newborn (for separations with at least one qualified day) or was not
181
reported. That is, separations for episode of care types Rehabilitation, Palliative care, Nonacute care, Other care and Newborn (for separations with unqualified days only) are
excluded where they were able to be identified (see Table 5.11). Of the separations for
which the type of episode of care was reported, 93% were reported as Acute (92%,
3,707,377 of 4,030,176 in the public sector and 94%, 1,926,275 of 2,058,005 in the private
sector). For public psychiatric hospitals 89% of separations for which the type of episode of
care was reported were Acute.
Tables are presented with summary separation, patient day and average length of stay
statistics for public and private hospitals, nationally and by State and Territory. National
information on age group and sex distributions is also presented.
The average length of stay figures were calculated using all separations. That is, the data
were not trimmed of separations with unusually long or short lengths of stay.
Some data for private hospitals in Tasmania and the Australian Capital Territory have not
been included in Tables 10.4, 10.10 and 10.12. These data were supplied but are not
published, for confidentiality reasons.
Cost weights and costs by volume
For each AR-DRG 1998–99 cost weights were used for the public and private sectors.
These had been estimated by the Department of Health and Aged Care, through the
National Hospital Cost Data Collection (Department of Health and Aged Care 2000). Cost
weights for 1999–00 were not available at the time of printing.
The cost weights represent the costliness of an AR-DRG relative to all other AR-DRGs,
such that the average cost weight for all separations is 1.00. The data collection also
provided estimates of average costs for each separation for an AR-DRG with a cost weight
of 1.00: $2,488 in the public sector and $1,903 in the private sector. Separate cost weights
are estimated for the public and private sectors because of the differences in the range of
costs recorded in public and private hospitals.
The Cost by volume figures in this chapter were derived for each AR-DRG by multiplying
the estimated average cost for the AR-DRG by the number of separations for the AR-DRG.
For MDCs, the cost estimates for all the AR-DRGs within the MDC were then summed to
produce an estimated cost for the MDC.
The Cost by volume figures in this chapter are estimates only, intended for use as a guide to
the approximate relative costs of hospital services during 1999–00. They should be used
with caution in any comparisons of the States and Territories or the public and private
sectors. They are not derived from, or comparable with, the expenditure and cost per
casemix-adjusted separation information presented in Chapters 2 and 3.
Information based on the average cost weights of separations is also included in Chapters
2, 4 and 5. Updated information will be included on the Internet at
http://www.aihw.gov.au/ publications/hse/ahs99-00/index.html, once 1999–00 cost
weights become available.
Appendix 8 includes further information on the National Hospital Cost Data Collection.
AR-DRGs and other data elements reported for separations
The information on AR-DRG reported in this chapter is compiled in the National Hospital
Morbidity Database with a range of other data. Figure 10.1 demonstrates this using the
182
example of the AR-DRG F42B Circulatory disorders without AMI with invasive cardiac
investigative procedure without complex diagnosis/procedure.
There were 41,050 separations with an AR-DRG of F42B, with an average length of stay of
1.6 days. The majority of separations were in the private sector (54.5%), and 52.6% of
separations were for private patients (in comparison to 33.8% overall, Table 5.1). Sixtythree per cent of patients were males and the most common age group reported was 65 to
74 years (12,307, 30.0%). The majority of patients (38,474, 93.2%) had a separation mode
of Other, suggesting that most of these persons went home after separation from hospital.
The most common principal diagnosis reported in conjunction with an AR-DRG of F42B
was Atherosclerotic heart disease, of native coronary artery (I25.11), while the most common
additional diagnosis was Essential (primary) hypertension (I10). The most common
procedure performed was Coronary angiography with left heart catherisation (procedure
code 38218–00 [Block 668]).
Major Diagnostic Categories
Sector
Figures 10.2 and 10.3 provide a summary of the numbers of separations and patient days
reported for each of the MDCs by sector.
The MDC with the highest number of separations in the public sector was Diseases and
disorders of the kidney and urinary tract (MDC 11), followed by Diseases and disorders of the
digestive system (MDC 06). In the private sector, Diseases and disorders of the digestive
system (MDC 06) had the largest number of separations, followed by Diseases and disorders
of the musculoskeletal system and connective tissue (MDC 08). For the public sector the
highest numbers of patient days were reported for the Diseases and disorders of the
circulatory system (MDC 05) and Mental diseases and disorders (MDC 19) MDCs. The
Diseases and disorders of the musculoskeletal system and connective tissue (MDC 08) and
Diseases and disorders of the digestive system (MDC 06) MDCs accounted for the highest
numbers of patient days in the private sector. For the public and private sectors combined,
the two MDCs with the most separations were Diseases and disorders of the digestive system
(MDC 06) and Diseases and disorders of the kidney and urinary tract (MDC 11). The largest
numbers of patient days were reported for the Diseases and disorders of the musculoskeletal
system and connective tissue (MDC 08) and Diseases and disorders of the circulatory system
(MDC 05) MDCs.
The average lengths of stay varied by MDC and hospital sector (Tables 10.1 and 10.2). In
the public sector, they ranged from 28.7 days for the Pre-MDC group to 1.5 days for
Diseases and disorders of the kidney and urinary tract (MDC 11) and Diseases and disorders of
the eye (MDC 02). In the private sector, the longest average length of stay was 27.0 days
for the Pre-MDC group, and the shortest was 1.1 days, for Diseases and disorders of the eye
(MDC 02).
Notable differences between hospital sectors were for Pregnancy, childbirth and puerperium
(MDC 14), where the average length of stay was higher for private hospitals (3.9 days)
than public hospitals (2.9 days), Newborns and other neonates (MDC 15), where the average
length of stay was higher in public hospitals (8.2 days) than private hospitals (6.1 days),
Infectious and parasitic diseases (MDC 18), where the average length of stay was higher for
private hospitals (6.1 days) than public hospitals (4.8 days), Mental diseases and disorders
183
(MDC 19), where the average length of stay was higher for public hospitals (10.5 days)
than private hospitals (5.6 days), and Alcohol/drug use and alcohol/drug induced organic
mental disorders (MDC 20), where the average length of stay was higher for private
hospitals (5.7 days) than public hospitals (4.2 days). A variety of factors could be
responsible for such discrepancies, for example different patient populations (and numbers
of separations for AR-DRGs within the MDCs), patterns of service provision, facilities
available, treatment regimes and reporting practices.
Almost 88% of patients in public hospitals were public patients, in contrast to just 3.7% in
private hospitals. The highest proportion of public patients in public hospitals was for
Alcohol/drug use and alcohol/drug induced organic mental disorders (MDC 20, 96.2%), while
the lowest was for Diseases and disorders of the eye (MDC 02, 77.6%). The highest
proportion of public patients in private hospitals was for Diseases and disorders of the kidney
and urinary tract (MDC 11, 12%), followed by Newborns and other neonates (MDC 15, 9.4%).
The cost by volume data for MDCs in Tables 10.1 and 10.2 show that the costliest MDC in
the public sector was estimated to be Diseases and disorders of the circulatory system (MDC
05). In the private sector it was Diseases and disorders of the musculoskeletal system and
connective tissue (MDC 08).
States and Territories
Tables 10.3 to 10.6 contain detail on the number of separations and patient days by MDC
in the States and Territories. These tables enable State by State comparisons of overall
hospital use for the different MDCs, and the share of separations between the public and
private sectors. For example, the proportion of total separations for Diseases and disorders
of the respiratory system (MDC 04) in private hospitals (rather than public hospitals) was
higher in Queensland (28.6%, 16,481) than in the other jurisdictions, for example New
South Wales (15.6%, 15,368). The proportion of total patient days for Pregnancy, childbirth
and the puerperium (MDC 14) that was in private hospitals (rather than public hospitals)
was 29.5% overall (411,476), but varied between States and Territories, for example 23.0%
in South Australia (25,443), 27.1% in New South Wales (128,933) and 40.4% in Western
Australia (59,703).
The distributions of separations and patient days by MDC within the States and Territories
were broadly consistent with those at the national level. Notable exceptions in the public
sector included Neoplastic disorders (MDC 17) in the Northern Territory (1.0% of
separations, 588, compared with a national average of 4.4%, 164,925) and Diseases and
disorders of the kidney and urinary tract (MDC 11) in the Australian Capital Territory
(23.1%, 13,850, compared with 15.8%, 591,545). In the private sector, South Australia and
Western Australia reported fewer separations for Diseases and disorders of the digestive
system (MDC 06) (15.4% of separations, 24,262, and 15.8% of separations, 33,333,
compared with 18.7%, 366,061, nationally).
Australian Refined Diagnosis Related Groups
Sector
Tables 10.7 to 10.16 present information on the most commonly reported AR-DRGs. Tables
10.7 and 10.8 contain summary separation, patient day and average length of stay
statistics for the 30 AR-DRGs with the most separations in public and private hospitals.
184
In the public sector in 1999–00 Admit for renal dialysis (AR-DRG L61Z) was the most
common AR-DRG, accounting for 12.4% (466,701) of total separations (Table 10.7). Other
leading AR-DRGs included Chemotherapy (AR-DRG R63Z) with 3.1% (116,662), and
Vaginal delivery without complicating diagnosis (AR-DRG O60D) with 3.0% (111,129) of
total public sector separations. The corresponding top three AR-DRGs in the private sector
were Other colonoscopy, same day (AR-DRG G44C) with 6.9% (135,901) of total
separations, Other gastroscopy for non-major digestive disease, same day (AR-DRG G45B)
with 4.9% (95,098), and Chemotherapy (AR-DRG R63Z) with 4.6% (90,512) (Table 10.8).
Of the 10 AR-DRGs with the most separations for the public sector, three were not
included in the top 30 for the private sector, namely Chest pain (AR-DRG F74Z),
Oesophagitis, Gastroenteritis and miscellaneous digestive system disorders age >9 without
catastrophic severe complication or comorbidity (AR-DRG G67B) and Other antenatal
admission with moderate or no complicating disorder (AR-DRG O65B). On the other hand,
none of the leading 10 AR-DRGs in the private sector was missing from the top 30 for the
public sector.
Within the top 30, average lengths of stay ranged from 5.9 days for Heart failure and shock
without catastrophic complication or comorbidity (AR-DRG F62B) to one day for six different
AR-DRGs in the public sector and from 6.5 days for Caesarean delivery without complicating
diagnosis to one day for twelve different AR-DRGs in the private sector.
The highest proportion of public patients in public hospitals was for Poisoning/toxic effects
of drugs and other substances age <60 without catastrophic complication or comorbidity (ARDRG X62B, 95.9%), while the lowest was for Dental extraction and restorations (AR-DRG
D40Z, 75%). The highest proportion of public patients in private hospitals was for Admit
for renal dialysis (AR-DRG L61Z, 18.6%), with less than 10% for each of the remaining ARDRGs.
The highest costs in public hospitals were estimated to be for Vaginal delivery without
complicating diagnosis (AR-DRG O60D) followed by Admit for renal dialysis (AR-DRG
L61Z). In the private sector, the costliest AR-DRGs in the top 30 were estimated to be
Major lens procedures (AR-DRG C08Z) and Other colonoscopy, same day (AR-DRG G44C).
States and Territories
There was some variation between the States and Territories in the relative number of
separations for the most common AR-DRGs (Tables 10.9 and 10.10). For example, in the
public sector in the Northern Territory and the Australian Capital Territory, Admit for
renal dialysis (AR-DRG L61Z) accounted for a markedly greater proportion of separations
than the national average (33.2%, 18,899, and 20.3%, 12,175, respectively, compared with
12.4%, 466,701).
In the private sector, examples of differences include separations in the Australian Capital
Territory: Other gastroscopy for non-major digestive disease, same day (AR-DRG G45B) which
accounted for a lower proportion of total separations than the national average (0.4%, 94,
compared with 4.9%, 95,098), and Other colonoscopy, same day (AR-DRG G44C) (1.0%,
227, compared with 6.9%, 135,901). This is likely to reflect the fact that private freestanding day hospital facilities in the Australian Capital Territory are not included in the
National Hospital Morbidity Database. In Western Australia, Non-surgical neck and back
conditions with pain management procedure/myelogram (AR-DRG I68C) accounted for 2.1%
of separations (4,457), compared with the national average of 0.7% (14,187).
The average lengths of stay were mainly similar among the States and Territories (Tables
10.11 and 10.12). However, there was some variation. In the public sector, Other factors
influencing health status age <80 without complication or comorbidity (AR-DRG Z64B) ranged
185
from 4.8 days in the Northern Territory to 1.6 days in the Australian Capital Territory and
Heart failure and shock without catastrophic complication and comorbidity (AR-DRG F62B)
ranged from 5.3 days in Victoria to 7.7 days in Tasmania. In the private sector, variation in
lengths of stay was evident for AR-DRGs such as Non-surgical neck and back conditions with
pain management procedure/myelogram (AR-DRG I68C), Other skin graft and/or debridement
procedures (AR-DRG J08B) and Caesarean delivery without complicating diagnosis (AR-DRG
O01D)
Age group and sex
Tables 10.13 and 10.14 summarise separations by age group and sex for the 30 leading
AR-DRGs. Fifteen of the top 30 AR-DRGs were common to both sexes, while some others
were more sex-specific (for example, Vaginal delivery without complicating diagnosis (ARDRG O60D). Admit for renal dialysis (AR-DRG L61Z) was the most commonly reported
AR-DRG for both sexes, with the most separations in the 65 to 74 years age group.
The age distributions varied by AR-DRG. For example, Tonsillectomy or adenoidectomy (ARDRG D11Z) was most commonly reported for males and females in the 5 to 14 years age
group. Knee procedures (AR-DRG I18Z) was most commonly reported for males in the 35 to
44 years age group and for females in the 45 to 54 years age group, and 55% of
separations (58,086) for Major lens procedure (AR-DRG C08Z) were for persons over the
age of 75 years.
Private free-standing day hospitals
Table 10.15 contains summary separation, public patient separation and patient day
statistics for the 30 AR-DRGs with the most separations in private free-standing day
hospital facilities. Other colonoscopy, same day (AR-DRG G44C) was the most common ARDRG, accounting for 16.9% (47,222) of total separations. Other leading AR-DRGs included
Other gastroscopy for non-major digestive disease, same day (AR-DRG G45B) with 14.0%
(39,083), and Major lens procedures (AR-DRG C08Z) with 9.4% (26,268) of total
separations. The proportion of public patient separations was highest for Circulatory
disorders without acute myocardial infarction with invasive cardiac investigative procedure
without complex diagnosis or procedure (AR-DRG F42B, 51.1%), with less than each of the
10% for the remaining AR-DRGs.
Public psychiatric hospitals
In public psychiatric hospitals, most of the separations had AR-DRGs reported that were
within the mental diseases and disorders, and alcohol/drug use and alcohol/drug
induced organic mental disorders MDCs (AR-DRGs beginning with U or V, respectively)
(Table 10.16). Personality disorders and acute reactions (AR-DRG U67Z) accounted for the
most separations, while Schizophrenia disorders with mental health legal status (AR-DRG
U61A) accounted for the most patient days. Major affective disorders age <70 without
catastrophic or severe complication or comorbidity (AR-DRG U63B) ranked second for
separations and Dementia and other chronic disturbances of cerebral function (AR-DRG B63Z)
for patient days.
The average length of stay was long for most of these AR-DRGs and only 14.2% (2,275) of
separations were same day separations, compared with 46% in public hospitals overall.
The average length of stay for Personality disorders and acute reactions (AR-DRG U67Z) in
public psychiatric hospitals was 9.7 days and the average length of stay for Major affective
disorders age <70 without catastrophic or severe comorbidity or complication (AR-DRG U63B)
was 20.0 days.
186
Separations in public psychiatric hospitals include some with very long lengths of stay, up
to several years. Hence the average lengths of stay should be interpreted taking into
consideration the inclusion of some very long stay separations. The median lengths of stay
were markedly shorter than the average lengths of stay for Schizophrenia disorders with
mental health legal status (AR-DRG U61A) (18 days, compared with the average length of
stay of 54.9 days), Major affective disorders age <70 without catastrophic or severe comorbidity
or complication (AR-DRG U63B) (13 days, compared with the average length of stay of 20.0
days) and Dementia and other chronic disturbances of cerebral function (AR-DRG B63Z) (27
days, compared with the average length of stay of 203.4 days). (By definition, half the
separations have a shorter length of stay and half have a longer length of stay than the
median.)
Additional data
The accompanying tables on the Internet at http://www.aihw.gov.au/publications/
hse/ahs99-00/index.html provide national and State and Territory summary statistics for
public and private hospitals for each AR-DRG (as presented for the top 30 AR-DRGs in
Tables 10.7 and 10.8). For confidentiality, data for some AR-DRGs in the private sector
have been suppressed. The information was suppressed if there were fewer than 50
private hospital separations reported for the AR-DRG and fewer than three reporting
units (hospitals, or States or Territories where the hospitals were not individually
identified), or there were three reporting units and one contributed more than 85% of the
total separations, or two contributed more than 90% of the separations for the AR-DRG.
Error DRGs
Error DRGs are the groups to which records containing clinically inconsistent or invalid
information are assigned. Group 1 Error DRGs, 901Z, 902Z and 903Z, are assigned when
all the operating room procedures are unrelated to the MDC of the patient’s principal
diagnosis. Group 2 Error DRGs, 961Z, 962Z and 963Z, are assigned when a principal
diagnosis is coded which will not allow the patient to be assigned to a clinically coherent
DRG. Group 3 Error DRG, 960Z, is assigned when the principal diagnosis is invalid, or
when other necessary information is incorrect or missing (Department of Health and Aged
Care 1998).
Table 10.17 provides information on Group 1 Error DRGs for the 10 procedures with the
highest number of separations, by hospital sector and State and Territory. Table 10.18
provides information on Group 2 Error DRGs, for the 10 principal diagnoses with the
highest number of separations, by hospital sector and State and Territory. A higher
number of separations was assigned to Error DRGs for public hospitals (57.9%, 7,939 for
Group 1 and 41.2%, 1,623 for Group 2) than for private hospitals (42.1%, 5,766 for Group
1, and 58.1% 2,252 for Group 2).
Variation in the assignment of separations to Error DRGs is evident between the States
and Territories. In public hospitals the number of Group 1 Error DRGs ranged from 140 in
Tasmania to 2,532 in New South Wales. In private hospitals, the number of Group 1 Error
DRGs ranged from 67 in the Australian Capital Territory to 1,814 in New South Wales.
The number of Group 2 Error DRGs in public hospitals ranged from 3 in Queensland to
1,220 in New South Wales, while in private hospitals, the number of Group 2 Error DRGs
ranged from 5 in Western Australia to 1,706 in New South Wales.
187
Figure 10.4 shows Error DRGs as a percentage of all separations, by State and Territory.
Group 2 Error DRGs accounted for the lowest proportion of separations assigned to Error
DRGs, while Group 1 Error DRGs accounted for the highest proportion.
