acute care: Care provided to patients admitted to hospital that is intended to cure illness, alleviate symptoms of illness or manage childbirth.
acute otitis media: The general term for acute otitis media both with chestand without perforation. It is the presence of fluid behind the eardrum and at least one of the following: bulging eardrum, red eardrum, recent discharge of pus, fever, ear pain or irritability. A bulging eardrum, recent discharge of pus and ear pain are the most reliable indicators of acute otitis media..

admission: An admission to hospital. In this report, the term hospitalisation is used to describe an episode of hospital care that starts with the formal admission process and ends with the formal separation process. The number of separations has been taken as the number of admissions; hence, the admission rate is the same as the separation rate.
admitted patient: A patient who undergoes a hospital's formal admission process.
adverse event: An incident involving harm to a person receiving health care. It includes infections, falls and other injuries, as well as reactions or complications due to surgery and other procedures, medical devices or medication—some of which may be preventable. Adverse events in health care can occur inside or outside hospitals and can be the cause of hospitalisation as well. The rate of adverse events treated in hospital is used as an indicator of safety in Australia's health system.
age-specific rate: A rate for a specific age group. The numerator and denominator relate to the same age group.
age-standardisation: A way to remove the influence of age when comparing populations with different age structures. This is usually necessary because the rates of many diseases vary strongly (usually increasing) with age. The age structures of the different populations are converted to the same 'standard' structure, and then the disease rates that would have occurred with that structure are calculated and compared.

real expenditure: Expenditure that has been adjusted to remove the effects of inflation (for example, expenditure for all years has been compiled using 2015–16 prices). Removing the effects of inflation allows comparisons to be made between expenditures in different years on an equal dollar-for-dollar basis. Changes in real expenditure measure the change in the volume of goods and services produced (see constant prices).
reason for discharge (Australian Defence Force): The main reason recorded for a person’s separating (discharging) from the Australian Defence Force. Analysis by reason for discharge is presented for two broad groups: voluntary discharge—includes voluntary redundancies and resignations; and involuntary discharge—comprises personnel deemed unsuitable for further duty for disciplinary, medical and operational reasons. Involuntary discharge is further divided into discharge for medical reasons, and non-medical involuntary discharge (which includes being physically unfit for service, training failure and disciplinary reasons).
recent user (alcohol and other drugs): Someone who has used in the last 12 months.
record linkage: See data linkage.
recurrent expenditure: Spending (expenditure) on goods and services that are used during the year (for example, salaries). Compare with capital expenditure.
referred medical services: Non-hospital medical services that are not classified as primary health care (see unreferred medical services).
refugee: A person who is subject to persecution in their home country and in need of resettlement. The majority of individuals considered to be a refugee are identified by the United Nations High Commissioner for Refugees (UNHCR) and referred by the UNHCR to Australia.
relative income poverty: A situation where a family’s income is low compared with that of other families. It is assessed by the proportion of households with an equivalised income that is less than 50% of the national median equivalised household income.
relative risk: This measure is derived by comparing two groups for their likelihood of an event. It is also called the risk ratio because it is the ratio of the risk in the ‘exposed’ population divided by the risk in the ‘unexposed’ population. It is also known as the rate ratio.
relative survival (cancer): A measure of the average survival experience of a population of people diagnosed with cancer, relative to the ‘average’ Australian of the same sex and age, at a specified interval after diagnosis.
remoteness classification: Each state and territory is divided into several regions based on their relative accessibility to goods and services (such as to general practitioners, hospitals and specialist care) as measured by road distance. These regions are based on the Accessibility/Remoteness Index of Australia and defined as Remoteness Areas by either the Australian Standard Geographical Classification (ASGC) (before 2011) or the Australian Statistical Geographical Standard (ASGS) (from 2011 onwards) in each Census year. The five Remoteness Areas are Major cities, Inner regional, Outer regional, Remote and Very remote. See also rural.
Repatriation Pharmaceutical Benefits Scheme (RPBS): An Australian government scheme that provides a range of pharmaceuticals and wound dressings at a concessional rate for the treatment of eligible veterans, war widows/widowers, and their dependants.
reserve/reservist: An Australian Defence Force member in the active or inactive reserve forces of the Navy, Army or Air Force. Most members leaving full-time service make the transition to the inactive reserve forces, unless there are medical or other grounds preventing this.
respiratory condition: A chronic respiratory condition affecting the airways and characterised by symptoms such as wheezing, shortness of breath, chest tightness and cough. Conditions include asthma and chronic obstructive pulmonary disease (COPD)—which includes emphysema and chronic bronchitis.
resuscitation of baby: Active measure taken shortly after birth to assist the baby’s ventilation and heartbeat, or to treat depressed respiratory effort to correct metabolic disturbances.
revascularisation: A procedure to restore adequate blood flow to the heart or other part of the body, usually after the supply has been reduced or blocked, as in angina or a heart attack. Revascularisation includes methods such as angioplasty and coronary artery bypass graft surgery.
rheumatoid arthritis: A chronic, multisystem disease whose most prominent feature is joint inflammation and resulting damage, most often affecting the hand joints in symmetrical fashion. It can occur in all age groups but most commonly appears between ages 20–40. Its causes are not certain but involve auto-immune processes.
risk: The probability of an event’s occurring during a specified period of time.
risk factor: Any factor that represents a greater risk of a health disorder or other unwanted condition or event. Some risk factors are regarded as causes of disease; others are not necessarily so. Along with their opposites (protective factors), risk factors are known as determinants.
rural: Geographic areas outside urban areas such as towns and cities. In this report, rural and remote encompasses all areas outside Australia’s Major cities according to the remoteness classification of the Australian Statistical Geographic Standard. In many instances, the term ‘rural and remote’ is used interchangeably with the classification terms ‘regional and remote’.
saturated fats: Fats, most often of animal origin, that are solid at room temperature and whose fatty acid chains cannot incorporate additional hydrogen atoms. In excess, they tend to raise blood cholesterol.
screening (for health): A systematic method of detecting risk factors or suspicious abnormalities among people who are symptom free, so that health problems can be either prevented or followed up, diagnosed and treated as early as possible. Screening is usually done through special programs aimed at higher risk groups in the population. A variant of screening, often known as case-finding, is where clinicians opportunistically look for risk factors or abnormalities in people when seeing them for other reasons; for example, when many doctors routinely measure blood pressure in all patients consulting them.
screen time: Activities done in front of a screen, such as watching television, working on a computer, or playing video games.
separation (from hospital): The formal process where a hospital records the completion of an episode of treatment and/or care for an admitted patient—in this report, described by the term hospitalisation.
separation (from military service): See discharge.
service (Australian Defence Force): The three broad arms of the Australian Defence Force—the Navy, Army and Air Force.
serving full time (Australian Defence Force): A term that describes Australian Defence Force members serving in a regular capacity in the Navy, Army or Air Force on continuous full-time service, or participating in the gap year program.
severe or profound core activity limitation: The limitation of a person who needs help or supervision always (profound) or sometimes (severe) to perform activities that most people undertake at least daily—that is, the core activities of self-care, mobility and/or communication. See also core activity limitation and disability.
sexual violence: The occurrence, attempt or threat of sexual assault experienced by a person since the age of 15. Sexual violence can be perpetrated by partners in a domestic relationship, former partners, other people known to the victims, or strangers.
sexually transmissible infection: An infectious disease that can be passed from one person to another by sexual contact. Examples include chlamydia and gonorrhoea infections.
siblicide: A homicide where one sibling kills another sibling.
single-occasion risk (alcohol): A single-occasion risk, in the context of alcohol, is defined as the risk of alcohol-related injury arising from having a sequence of drinks without the blood alcohol concentration reaching zero in between them. The risk of an alcohol-related injury arising from a single occasion of drinking increases with the amount consumed. For healthy men and women, drinking no more than 4 standard drinks on a single occasion reduces the risk of alcohol-related injury from that occasion.
sleep apnoea: A situation that occurs when a person repeatedly stops breathing during sleep. It has the same cause as snoring—reduced air flow at the back of the mouth—but is more extreme. More common in males and the obese, it leads to poorer mental functioning during the day and a greater risk of accidents.
smartphone: A mobile phone built on a mobile operating system, with more advanced computing capability and connectivity.
smartwatch: A mobile device, consisting of a package that includes a computer and display, attached to a bracelet.
smoker: Someone who reports smoking daily, weekly or less than weekly.
social determinants of health: The circumstances in which people are born, grow up, live, work and age, and the systems put in place to deal with illness. These circumstances are in turn shaped by a wider set of forces: economics, social policies and politics.
social exclusion: A situation where people do not have the resources, opportunities and capabilities they need to learn, work, engage with or have a voice in their communities. Composite measures of social exclusion weight indicators such as income level, access to education, unemployment, poor English, health services and transport, and non-material aspects such as stigma and denial of rights. These measures are typically divided into three levels: marginal exclusion, deep exclusion and very deep exclusion.
Socio-Economic Indexes for Areas (SEIFA): A set of indexes, created from Census data, that aim to represent the socioeconomic position of Australian communities and identify areas of advantage and disadvantage. The index value reflects the overall or average level of disadvantage of the population of an area; it does not show how individuals living in the same area differ from each other in their socioeconomic group. This report uses the Index of Relative Socio-Economic Disadvantage.
socioeconomic position: An indication of how ‘well off’ a person or group is. In this report, socioeconomic areas are mostly reported using the Socio-Economic Indexes for Areas, typically for five groups (quintiles)—from the most disadvantaged (worst off or lowest socioeconomic area) to the least disadvantaged (best off or highest socioeconomic area).
solar ultraviolet (UV) radiation: High-energy rays from the sun which are invisible to the human eye. UV radiation is divided into three types according to wavelength (UVA, UVB and UVC). UVA, and to a lesser extent UVB, are not wholly absorbed by atmospheric ozone and therefore are of interest for human health.
specialist attendance: A specialist attendance is a referred patient-doctor encounter (with Medicare funding benefits), such as a visit, consultation and attendance (including a video conference) with a medical practitioner who has been recognised as a specialist or consultant physician for the purposes of Medicare benefits.
specialist services: Services that support people with specific or complex health conditions and issues, who are generally referred by primary health care providers. They are often described as ‘secondary’ health care services. In many cases, a formal referral is required for an individual to be able to access the recommended specialist service.
spontaneous labour: The onset of labour without intervention.
standard drink (alcohol): A serve that contains 10 grams of alcohol (equivalent to 12.5 millilitres of alcohol). It is also referred to as a full serve.
Staphylococcus aureus bacteraemia (SAB): An infection of the bloodstream. When associated with health care procedures, these infections are considered to be potentially preventable.
statins: A class of drugs commonly used to lower blood cholesterol.
statistical significance: A statistical measure indicating how likely the observed difference or association is due to chance alone. Rate differences are deemed to be statistically significant when their confidence intervals do not overlap, since their difference is greater than what could be explained by chance.
stillbirth: See fetal death (stillbirth).
stroke: An event that occurs when an artery supplying blood to the brain suddenly becomes blocked or bleeds. A stroke often causes paralysis of parts of the body normally controlled by that area of the brain, or speech problems and other symptoms. It is a major form of cerebrovascular disease.
substance misuse: Use of illicit drugs (illegal drugs, drugs and volatile substances used illicitly, and pharmaceuticals used for non-medical purposes).
substance use disorder: A disorder of harmful use and/or dependence on illicit or licit drugs, including alcohol, tobacco and prescription drugs.
suicidal ideation: Serious thoughts about ending one’s own life.
suicidality: The collective term for suicidal ideation, suicide plans and suicide attempts.
suicide: An action to deliberately end one’s own life.
sulfonylureas: A class of medicines that lower blood glucose levels by stimulating the pancreas to release more insulin.
suppurative: A term that describes pus produced in response to inflammatory bacterial infections.
syphilis (infectious): A sexually transmitted infection, which if untreated can cause irreversible damage. It is caused by Treponema pallidum bacteria. It is a notifiable disease.
tablet (information and communication technologies): A hand-held, internet-enabled, wireless personal computer, usually having a touchscreen or a digital pen-enabled interface, and no hardware keyboard.
telehealth: Health services delivered using information and communication technologies, such as videoconferencing.
thromboembolism: The obstruction of a blood vessel, usually a large vein, with thrombotic material carried in the blood from its site of origin to block another vessel.
tooth decay: Decay of the teeth caused by caries, and progressing to cavities in the enamel and the dentine.
trachoma: An infectious disease of the eye caused by Chlamydia trachomatis. If left untreated, follicles form on the upper eyelids and grow larger until the granulations invade the cornea, eventually causing blindness.
Transition (Australian Defence Force): In the context of military services, the process of moving from full-time Australian Defence Force service into civilian life.
treatment episode: The period of contact between a client and a treatment provider or a team of providers. In the context of alcohol and other drug treatment, each treatment episode has 1 principal drug of concern and 1 main treatment type. If the principal drug or main treatment changes, a new episode is recorded.
treatment type: In the context of alcohol and other drug treatment, the type of activity that is used to treat the client’s alcohol or other drug problem. Examples include assessment only, counselling, information and education only, pharmacotherapy, rehabilitation, support and case management only, and withdrawal management (detoxification).
triage category: A category used in the emergency departments of hospitals to indicate the urgency of a patient’s need for medical and nursing care. Patients are triaged into 1 of 5 categories on the Australasian Triage Scale. The triage category is allocated by an experienced registered nurse or medical practitioner.
triglyceride: A compound made up of a single molecule of glycerol and three molecules of fatty acid. Triglycerides are the main constituents of natural fats and oils.
type 1 diabetes: A form of diabetes mostly arising among children or younger adults and marked by a complete lack of insulin. Insulin replacement is needed for survival. See diabetes (diabetes mellitus).
type 2 diabetes: The most common form of diabetes, occurring mostly in people aged 40 and over, and marked by reduced or less effective insulin. See diabetes (diabetes mellitus).
Under-five mortality rate: see child mortality rate.
underlying cause of death: The disease or injury that initiated the train of events leading directly to death, or the circumstances of the accident or violence that produced the fatal injury. See also cause of death and associated cause(s) of death.
underweight: A category defined for population studies as a body mass index less than 18.5.
unreferred medical service: A medical service provided to a person by, or under the supervision of, a medical practitioner—being a service that has not been referred to that practitioner by another medical practitioner or person with referring rights. In this report, these are medical services that are classified as primary health care (see referred medical services).
vaccination: The process of administering a vaccine to a person to produce immunity against infection. See immunisation.
vacuum extraction: A procedure to assist birth using traction or rotation on a suction cap applied to the baby’s head.
vascular risk factors: Metabolic and behavioural risk factors that increase the risk of vascular disease. They also increase the risk of some vascular diseases themselves (‘diseases-as-risks’, such as diabetes, stroke, atrial fibrillation and chronic kidney disease) that involve or increase the risk of damaged blood vessels, and which jointly and individually increase the risk of dementia.
vector-borne disease: A disease, parasite or infection transmitted from one host to another by a vector. The largest group of vectors are insects and other arthropods, most commonly mosquitoes, ticks, flies, lice and fleas. The abundance and distribution of vector populations (and hence the spread of vector-borne diseases) is closely intertwined with environmental conditions that encourage their survival.
weighting: Adjustment of the characteristics of one group so they are statistically similar to the characteristics of another group so that comparisons of the effect under study can be more certain.
wellbeing: A state of health, happiness and contentment. It can also be described as judging life positively and feeling good. For public health purposes, physical wellbeing (for example, feeling very healthy and full of energy) is also viewed as critical to overall wellbeing. Because wellbeing is subjective, it is typically measured with self-reports, but objective indicators (such as household income, unemployment levels and neighbourhood crime) can also be used.
whooping cough: See pertussis.
workforce: People who are employed or unemployed (not employed but actively looking for work). Also known as the labour force.
years lived with disability (YLD): A measure calculated as the prevalence of a condition, multiplied by a disability weight for that condition. Sometimes referred to as years of healthy life lost due to disability (YLD).
years of healthy life lost due to disability: See years lived with disability (YLD).
years of life lost (YLL): For each new case, years of life lost equals the number of years between premature death and the standard life expectancy for the individual.
