Hospitalisations
Total hospitalisations
Measures
- Number of hospitalisations (excluding dialysis).
- Crude rate (per 1,000) of hospitalisations (excluding dialysis).
- Age-standardised rate (per 1,000) of hospitalisations (excluding dialysis).
Available by
- Sex: males, females, persons.
- Age group: 0–14, 15–24, 25–49, 50 and over, all ages.
- Indigenous status: First Nations, non-Indigenous.
Data periods
Current year: 2019–20 to 2023–24 (combined).
Data sources
AIHW analysis of National Hospital Morbidity Database (NHMD).
Region types
Main structure: Australia, states and territories, Greater Capital City Statistical Areas (GCCSA), Statistical Area Level 4 (SA4), Statistical Area Level 3 (SA3).
Data for GCCSA, SA4 and SA3 are presented for ‘urban areas’ only.
Suppression
- Data have been suppressed to protect confidentiality when the number of hospitalisation episodes is less than 5, including the use of consequential suppression to prevent back-calculation.
- Crude rates have been suppressed where the denominator is <100.
- Age standardised rates have been suppressed where the number of events for all ages is <20, or the denominator in any age group is <30.
- When the numerator is suppressed, crude/age-specific rates or percentages are also suppressed.
- When the numerator for all ages is suppressed, the age-standardised rate is also suppressed.
Notes
- Geography is based on area of usual residence–Statistical Local Area Level 2 (SA2)–classified according to the Australian Statistical Geography Standard (ASGS) 2021 structure.
- Except for the Australian Capital Territory, data at the GCCSA, SA4 and SA3 level were aggregated from Statistical Areas Level 2 (SA2s) by truncating the digits of the SA2 codes. For the Australian Capital Territory, the state, GCCSA and SA4 data were identical as they pertained to the same geographic boundary.
- For the denominator in the rates, First Nations population estimates were modelled by the AIHW using ABS population estimates and projections (series b) based on the 2021 Census. Population estimates for non-Indigenous Australians were derived by subtracting First Nations population estimates from the total Australian estimated resident population. Population data align with 30 June each year.
- Age-standardised rates are directly age-standardised using the 2001 Australian standard population, by 5-year age groups up to 75+.
- Hospitalisations with the care types “newborn with unqualified days only” (7.3), “organ procurement - posthumous” (9) or “hospital boarder” (10) were excluded from the analysis.

- Hospitalisations with a principal diagnosis of dialysis (ICD-10 code Z49) were excluded from the analysis.
- The median length of stay is the middle value when all lengths of stay are arranged in order from shortest to longest. This means that half of the patients stayed for fewer days than the median, and half stayed for more. The median is the middle value in the dataset when the lengths of stay are arranged in ascending order.
- The mean (or average) length of stay is calculated by summing the total number of days all patients stayed in the hospital and dividing that sum by the total number of patients. The mean length of stay is calculated as the sum of all patients' lengths of stay divided by the number of patients. This gives the average number of days patients spend in the hospital.

- Data have been suppressed to protect confidentiality when the number of hospitalisation episodes is less than 5, including the use of consequential suppression to prevent back-calculation.
- Crude rates have been suppressed where the denominator is <100.
- Age standardised rates have been suppressed where the number of events for all ages is <20, or the denominator in any age group is <30.
- When the numerator is suppressed, crude/age-specific rates or percentages are also suppressed.
- When the numerator for all ages is suppressed, the age-standardised rate is also suppressed.
Notes
- Geography is based on area of usual residence–Statistical Local Area Level 2 (SA2)–classified according to the Australian Statistical Geography Standard (ASGS) 2021 structure.
- Except for the Australian Capital Territory, data at the GCCSA, SA4 and SA3 level were aggregated from Statistical Areas Level 2 (SA2s) by truncating the digits of the SA2 codes. For the Australian Capital Territory, the state, GCCSA and SA4 data were identical as they pertained to the same geographic boundary.
- For the denominator in the rates, First Nations population estimates were modelled by the AIHW using ABS population estimates and projections (series b) based on the 2021 Census. Population estimates for non-Indigenous Australians were derived by subtracting First Nations population estimates from the total Australian estimated resident population. Population data align with 30 June each year.
- Age-standardised rates are directly age-standardised using the 2001 Australian standard population, by 5-year age groups up to 75+.
- Hospitalisations with the care types “newborn with unqualified days only” (7.3), “organ procurement - posthumous” (9) or “hospital boarder” (10) were excluded from the analysis.
- Hospitalisations where Indigenous status was not stated (code 9) were excluded from the analysis.
- Hospitalisations with a principal diagnosis of dialysis (ICD-10 code Z49) were excluded from the analysis.
- Selected chronic conditions and ICD-10-AM codes:
- Cancer: principal diagnosis, C00-C97, D45-D46, Z08; ICD-10 codes at the 4-character level D471, D473-D475, Z510-Z511, Z541-Z542; ICD-10 codes at the 5-character level Z4000, Z4001.
- Chronic kidney disease: principal diagnosis, E102, E112, E132, E142, I150, I151, N391, N392, D593, B520, E853, T824, T861, Z490, Z940, Z992, I12, I13, N11, N12, N14, N15, N16, N18, N19, N00-N08, N25-N28, Q60-Q63.
- COPD: principal diagnosis, J40-J44.
- Coronary heart disease: principal diagnosis, I20-I25.
- Diabetes: principal diagnosis, E10-E11, E13-E14.
- Mental health: principal diagnosis, F00-F99 excluding F525, F842, F985-F986, G300-G301, G308-G309, G470-G472, G478-G479, O993, R440-R443, R448, R450-R451, R454, R480, R481-R482, R488, Z004, Z032, Z046, Z093, Z133, Z502-Z503, Z543, Z619, Z631, Z638-Z639, Z658-Z659, Z714-Z715, Z760.
Potentially preventable hospitalisations
Measures
- Number of potentially preventable hospitalisations (excluding dialysis).
- Age-standardised rate (per 1,000) of potentially preventable hospitalisations (excluding dialysis).
- Crude rate (per 1,000) of potentially preventable (excluding dialysis).
Available by
- Sex: males, females, persons.
- Age group: 0–14, 15–24, 25–49, 50 and over, all ages.
- Indigenous status: First Nations, non-Indigenous.
Data periods
- Current year: 2019–20 to 2023–24 (combined).
- Time trend: 2019–20, 2020–21, 2021–22, 2022–23, 2023–24.
Data sources
AIHW analysis of National Hospital Morbidity Database (NHMD).
Region types
Main structure: Australia, states and territories, Greater Capital City Statistical Areas (GCCSA), Statistical Area Level 4 (SA4), Statistical Area Level 3 (SA3).
Data for GCCSA, SA4 and SA3 are presented for ‘urban areas’ only.
Suppression
- Data have been suppressed to protect confidentiality when the number of hospitalisation episodes is less than 5, including the use of consequential suppression to prevent back-calculation.
- Crude rates have been suppressed where the denominator is <100.
- Age standardised rates have been suppressed where the number of events for all ages is <20, or the denominator in any age group is <30.
- When the numerator is suppressed, crude/age-specific rates or percentages are also suppressed.
- When the numerator for all ages is suppressed, the age-standardised rate is also suppressed.
Notes
- Potentially preventable hospitalisations (PPHs) were hospitalisations considered to have been avoidable if timely and adequate non-hospital care had been provided, either to prevent the condition occurring, or to prevent the hospitalisation for the condition. PPHs were classified using nationally agreed definitions (National Healthcare Agreement: PI 18–Selected potentially preventable hospitalisations, 2022).
