The formal process, using registration procedures, under which a person is accepted by a hospital or district health service facility as an inpatient.
A measure of the amount of disease associated with an exposure within a population. In a situation in which exposure to a given factor is believed to be a cause of a given disease, the population attributable fraction (or population aetiologic fraction) is the proportion of the disease in the total population that can be attributed to exposure to the factor.
Rate adjusted to take account of differences in age composition when rates for different populations are compared.
Rate for a specified age group. Both numerator and denominator refer to the same age group.
A response by the ambulance staff to a particular request for provision of care. Attendances are classified in several categories such as: cardiac, medical, surgical, trauma and routine attendance.
Services relating to the work of rendering first aid to, and the transport of, sick and injured persons.
See UNDERLYING cause of death.
A person who has been in association with an infected person or a contaminated environment that may provide an opportunity to acquire the infection.
An error margin illustrating the variability in statistics sampled from a population. A 95% confidence interval can be interpreted as a 95% probability that the true value of a variable (such as a rate, mean or proportion) is contained within the interval.
An estimate of the proportion of a population that dies in a specified period. It is calculated by dividing the number of deaths in a specified period by the number at risk during that period (typically per year).
A person who is admitted to hospital and leaves on the same calendar day.
All civilians aged 15 years and over who worked for pay or profit or worked without pay in a family business or farm.
Number of live births in an area during a year, divided by the mid-year female population aged 15-44 in the same area in the same year.
Delivery of a child who did not, at any time after delivery, breathe or show any other evidence of life, such as a heartbeat.
Used for non-medicinal purposes: speed, cocaine, sleeping pills or tranquilisers, marijuana, analgesics, heroin, petrol and other inhalants, hallucinogens, designer drugs, and injecting of any illegal drug.
The rate at which new cases of a disorder occur in the population: that is, the number of new cases in a specified period, divided by the population at risk of the disorder in that period.
The death of a child before its first birthday.
All persons aged 15 years and over who are employed and unemployed.
The average number of years of life remaining to a person at a particular age.
The birth of a child who, after delivery, breathes or shows any other evidence of life, such as a heartbeat. For calculation of perinatal death rates, includes only infants weighing at least 400 grams at birth or, where birth-weight is unknown, of at least 20 weeks gestation.
A geographical area under the responsibility of an incorporated local government council.
Health administration structures applicable in NSW since January 2011.
Also known as the arithmetic average. It tells where the values for a group (sample) are centred.
Death within 28 days of birth of any child who, after delivery, breathed or showed any other evidence of life, such as a heartbeat.
Certification in an approved form of a disease listed in Schedule 3 of Notifiable Diseases in the NSW Public Health Act 2010. In HealthStats NSW, notifications concern cases of communicable diseases reported by general practitioners, hospitals and pathology laboratories to the Director General of the NSW Ministry of Health.
The labour force expressed as a percentage of the civilian population aged 15 years and over.
Occurs following the arrival of the patient at the emergency department and is the earliest occasion of the patient being registered clerically or triaged. The patient may be subsequently provided with a service by a treating medical officer or nurse, and a provisional diagnosis is recorded. A 'presentation' is equal to a 'visit' or an 'attendance' at the emergency department.
A fetal or neonatal death.
A postcode is a four digit number used by Australia Post to assist with mail delivery. Australia Post does not currently define geographic boundaries for postcodes.
Postal Areas (POAs) are an Australian Bureau of Statistics (ABS) approximation of postcodes created to enable the release of ABS data on areas that, as closely as possible, approximate postcodes. This enables the comparison of ABS data with other data collected using postcodes.
Deaths occurring before the age 75 years, which could be avoided by clinical or other healthcare interventions.
Hospitalisations for certain conditions for which hospitalisation is considered potentially avoidable or preventable if earlier preventive care and disease management was provided ‘upstream’ of the hospitalisation. Usually delivered through primary health care.
A regional network governed by a Board and consisting of general practitioner-led Clinical Councils and Community Advisory Committees which report to the Board on issues to ensure services across the primary, community and specialist sectors in the region work together. Geographical boundaries of Primary Health Networks (PHNs) are formalised by the Australian Government Department of Health. There are nine Primary Health Networks in NSW. Primary Health Networks replace Medicare Locals.
The number of people with a disease at a given time (point prevalence) or in a specified period (period prevalence), divided by the number of people at risk from that disease.
The first ICD-9 or ICD-10 coding variable reported on the hospital separation form. It means the final diagnosis that best accounts for inpatient care.
The ratio of two rates: for example, the rate of disease in one population group divided by the rate in another population group.
Data warehouse and analysis tool based on SAS. It is managed by the Centre for Epidemiology and Evidence, NSW Ministry of Health, and employs sophisticated business intelligence technology to enable analysis of key health datasets. SAPHaRI replaced HOIST (Health Outcomes Information Statistical Toolkit) in 2012.
Medical conditions to be notified under the provisions of the NSW Public Health Act 2010.
The formal process whereby an inpatient leaves a hospital or other district health service facility after completing an episode of care (e.g. discharge to home, discharge to another hospital or nursing home, or death).
Measures the scatter in a group of observations. While the mean tells where the values for a group (sample) are centred, the standard deviation is a summary of how widely distributed the values are around the centre. Standard deviation describes how widely individuals within the survey sample differ from the sample mean. It may be unaffected by the increased sample size.
An estimate of how closely a sample mean is likely to be to the true mean (i.e. the mean of the population from which the sample was drawn). In other words, it is the standard deviation of an estimate of the mean. It is used to calculate confidence intervals. The larger the standard error, the less confident we are that the estimate from the sample is close to the true value. The bigger the sample (that is the closer the sample is to the total population) the smaller the standard error because the estimate of the population mean improves.
The primary disease or injury causing the death. It is listed on a death certificate together with other diseases or injuries, which are classified as associated causes. These are all other conditions, diseases or injuries that were considered to have contributed to the death.
Persons aged 15 years and over who were not employed and who were actively seeking work, or waiting to be called back to a job from which they had been stood down.
The number of unemployed expressed as a percentage of the labour force (i.e. employed and unemployed).
