The ongoing collection of population health data is used to gain a comprehensive picture of health and wellbeing and to monitor trends over time for key health indicators, such as prevalence of smoking and overweight and obesity.
Information about the health of populations offers governments and researchers important clues about health problems and emerging issues.
The findings provide evidence to:
- inform decisions about priorities for public health and wellbeing plans
- support strategic planning, reporting and decision-making
- evaluate programs and initiatives
- inform and refine public health policies
- improve the quality and delivery of health services.
Data are reported in the biennial Chief Health Officer’s Report and contribute to various ACT Government reports, including (but not limited to) Focus On reports and the Community Services Directorate report: ‘A Picture of ACT’s Children and Young People’
Epidemiology Survey Program
ACT General Health Survey (ACTGHS)
Each year, ACT Health conducts the ACTGHS by computer-assisted telephone interview (CATI) with randomly-selected households. The target is to survey 1200 adults of all ages and 500 children aged 2-15 years living in Canberra.
The survey, which commenced in 2007, is important because national health surveys tend to only include a small number of people from the ACT.
The ACTGHS is based on core questions related to self-reported health status and health behaviours, including:
- Self-rated health
- Oral health
- Physical activity
- Alcohol consumption
- Tobacco use
- Mental health
- Self-reported height and weight.
The ACTPANS has been conducted every three years since 2006. It is administered by professional survey staff, on behalf of ACT Health, in the classroom setting.
Information about physical activity, nutrition, healthy weight status, attitudes and general wellbeing indicators are collected. Height and weight are also measured.
Questionnaire items include:
- eating patterns and food intake levels
- physical activity and sedentary behaviour
- attitudes to physical activity
- general health and wellbeing.
In 2018, 1,491 ACT Year 6 students from 30 primary schools across the ACT participated in the ACTPANS; for more information, contact: HealthSurvey@act.gov.au
Commencing in 1984, and conducted in the ACT since 1996, the triennial national ASSAD survey series is designed to provide estimates of the current prevalence of tobacco, alcohol and illicit substance use among Australian secondary school students and to examine trends in their use over time.
The ASSAD uses a standard sampling procedure, administration method and core questionnaire throughout all states and territories of Australia. A consistent method for sampling and recruiting schools and administering the survey has been used in all rounds of the survey. In addition, the same questions have been used to assess substance use behaviours. This design allows the data to be compared from one survey year to another and changes in the prevalence of use between survey years can be examined.
The ASSAD survey is coordinated nationally by the Cancer Council Victoria, with each of the states and territories managing the data collection within their own jurisdiction. Results are reported to the National Drug Strategy, a co-operative venture between Australian, state and territory governments and the non-government sector, whose aim is to improve health, social and economic outcomes for Australians by preventing the uptake of harmful drug use and reducing the harmful effects of licit and illicit drugs in our society.
In 2017, ~1,491 secondary students aged between 12 and 17 years from 19 schools across the ACT participated in the ASSAD; for more information, contact: email@example.com or HealthSurvey@act.gov.au
ACT Cancer Registry
The ACT Cancer Registry was established in 1994, when cancer reporting became mandatory in the ACT. Data was collected from 1985 but it is not considered complete prior to mandatory reporting. The purpose of the ACT Cancer Registry is to monitor the incidence and trends of cancer in the ACT. Data are collected from hospital records, pathology laboratories, day surgeries, hospices and nursing homes. About 1,000 to 2,000 new cases are reported each year. Currently, there are approximately 33,000 records in the registry. The registry does not cover non-melanocytic skin cancer (ie basal cell carcinoma and squamous cell carcinoma).
ACT Maternal Perinatal Data Collection
The ACT Maternal Perinatal Data Collection is a population-based collection covering all births in ACT hospitals (public and private) and home births in the ACT. It does not include interstate births where the mother is usually resident in the ACT. Each data set includes all live births and still births of at least 20 weeks gestation or at least 400 grams birthweight and covers such topics as mother’s demographics, type of induction, method of birth, malformations, and apgar scores at birth. The data are managed and maintained by the Epidemiology Section within ACT Health. The ACT MPDC is linked to the ACT APC data to provide maternal condition and complications, and birth defects information.
Other ACT Health data we use:
ACT Admitted Patient Care Collection (ACT APC)
The data sets in this collection contain details of all ACT hospital inpatient records. It details patient records from each of the public and private hospitals in the ACT, for ACT and non-ACT residents. The information reported includes patient demographics, diagnoses, procedures, source of referral etc. The data do not include details of ACT residents admitted to hospitals outside the ACT.
ACT Emergency Department Information System (EDIS)
The ACT Emergency Department Information System contains records of patient presentations to the Canberra Hospital and Calvary Hospital Emergency Departments. The EDIS data contain details of patient demographics and diagnoses, triage categories and sources of referral.
Kindy Screen - Kindergarten health check
The Kindergarten Health Check (KHC) is a community based screening program that provides health checks for the whole of the 5 or 6-year old kindergarten population of children attending kindergarten in the ACT. The ACT KHC program in its present form has been running since 1998. Registered and enrolled nurses employed by ACT Health conduct the Kindergarten Health Check in all ACT primary school throughout the year. The health check includes vision, hearing, weight and development.
Data linkage is a process of linking information from people held in different data collections together to create a study dataset that contains information about a person, group or population that is relevant to specific health conditions, treatments or outcomes. For example, to identify modifiable risk factors for birth outcomes, or to compare differences in outcomes for diseases such as cardiovascular disease or cancer between different population groups.
Data linkage can be used for epidemiological research, population health surveillance, health system performance monitoring, and program evaluation, as well as social research. It helps to meet government needs for information and to provide a way for researchers to study health and social factors in populations.
The Population Health Division (through the Epidemiology Section) is a founding partner of the Centre for Health Record (CHeReL) at NSW Health. The CHeReL provides data linkage infrastructure and services for the linkage of ACT administrative data collections, such as the ACT Cancer Registry, Maternal Perinatal Data Collection, Admitted Patient Care (APC) and Emergency Department (ED) records from public hospitals, and the ACT Notifiable Diseases Management System, and births and deaths from the ACT Registrar of Births, Deaths and Marriages.
All data linkage is conducted according to best practice data governance processes and policies to protect the privacy and confidentiality of its records at all times. All projects using linked data must obtain approval from the data custodians and a human research ethics committee. The CHeReL also complies with best practice in privacy preserving record linkage.
The data is presented by the ACT Government for the purpose of disseminating information for the benefit of the public. The ACT Government has taken great care to ensure the information in this report is as correct and accurate as possible. Whilst the information is considered to be true and correct at the date of publication, changes in circumstances after the time of publication may impact on the accuracy of the information. Differences in statistical methods and calculations, data updates and guidelines may result in the information contained in this report varying from previously published information.
