1 Nation-wide CATI Health Surveys National CATI Technical Reference Group

2 Nation-wide CATI Health Surveys National CATI Health Survey Technical Reference Group > has been providing leadership in CATI health surveys The National Public Health Partnership and AHMAC have expressed an interest in CATI health surveys >as an integral part of a nation-wide chronic disease and behavioural risk factor surveillance and monitoring system Development of Nation-wide CATI Health Surveys is based on the importance of State CATI surveys: >to provide high quality health data at the State level to track and monitor current and emerging health related issues, and >is a critical national/state partnership for the health of Australians *CATI - Computer Assisted Telephone Interviewing

3 Nation-wide Key Principles Key principles of the Nation-wide CATI Health Surveys are: ongoing rolling program National core question modules State specific question modules capacity for optional question modules Nation-wide CATI Health Surveys will make a difference by: having a population health focus being part of an evidence based approach demonstrating links to interventions supporting epidemiological studies based on surveillance *there is a need for a code of ethics and a code of practice

4 Role of CATI Health Surveys CATI health surveys have been developed to address population health and surveillance needs They provide key support for population health policy development and intervention National CATI Health Survey Technical Reference Group is seeking to develop nation-wide capacity by: >collaboration with CATI and non-CATI collections >development of a national sample through Telstra >development of agreed question modules

5 Best Evidence from CATI health surveys Information gathered from CATI health surveys provides important input into the development and monitoring of population health interventions and programs with: CATI health surveys providing the ability to compare key health data between States and regions as well as identifying changes over time the provision of a valuable resource to aid in consultation with the providers and users of health services ongoing timely data providing key information to challenge existing views such as the trends in the use of services the provision of vital input into the evaluation of, and competition between, services including health service use and satisfaction

6 CATI TRG Workprogram The current CATI Technical Reference Group workprogram covers: the convening of a 2-day national forum (held in Adelaide in February 2000) and the publishing of the forum papers the preparation of a best practice paper telecommunication discussions to provide a uniform/optimal sampling mechanism the standardising of question modules with a focus on NHPAs an examination of social capital the development of a coordinated communications strategy developing State/Territory collaboration buddy systems

7 Why Use CATI Health Surveys CATI health surveys are used to collect key population health surveillance data as they provide: timeliness of the collection and reporting of the information efficient use of current technology flexible and responsive collection that is adaptable to changing and emerging information needs cost effective collection procedures rural and regional data fill policy and strategic information gaps information not available from other sources access to unit records to facilitate extensive analysis and interpretation

8 Why Use CATI Health Surveys (continued) In addition CATI health surveys are used to collect key population health surveillance data as they provide: time series acceptable collection procedures to respondents adequate sample size high data quality, especially through greater supervision of interviewers, computer data entry and question sequencing support to government public relations collection that is safe for interviewers and respondents interstate, national and international comparisons capacity to extend collection to include an epidemiological focus

9 Complementary Methods Complementary collection methodologies are required for particular population groups, such as: >Indigenous persons >non-English speaking persons >low socio-economic population Mixed mode data collection for questions more suited to non-CATI procedures (eg attitudinal questions collection in follow-up mail collections)

10 Current CATI Activity The scope of topics being covered by State based CATI surveys include: monitoring and surveillance specific issues such as communicable diseases health priority areas including prevalence, incidence, risk factors, management, links to biomedical measures anthropological dimensions such as social capital environmental issues health promotion activities health service use and evaluation

11 Current CATI Output There have been a wide range of outputs including: reports scientific and general publications workshops and conferences interstate, national and international comparisons internet publication, eg see sites such as: >www.health.nsw.gov.au/public-health/hs97 >hna.ffh.vic.gov.au/phd/ /index.htm >www.health.sa.gov.au/pehs/CPSE.html >www.health.act.gov.au/epidem/hps.html

12 Development Options Development options for Nation-wide CATI Health Surveys include: pilot testing State/Territory collaboration buddy systems national module development publication of a best practice manual a national co-ordination program further analysis of current data holdings communication strategy obtaining a Telstra sample

13 Future Directions The medium term future directions include: pilot testing State/Territory collaboration buddy systems development of a national CATI rural/remote survey development of new question modules covering social disadvantage, chronic disease, nutrition, physical activity, immunisation and child health documenting what each State/Territory is doing and has completed examine statistically significant similarities/differences between States to identify CATI results that can be generalised to other States

14 Selected State Examples The following slides provide some examples of data that have been collected in State CATI health surveys: South Australian Health Omnibus Surveys 1991 to 1999 – Proportion with current, confirmed asthma and prevalence of diabetes NSW Health Survey 1997 – Overweight/obesity, physical activity and private health insurance Victoria Population Health Survey 1999 – Use of personal protective equipment in sport and understanding of disease inheritance

15 SA Health Omnibus Surveys 1991 – 1999 The following charts show a time series of two of the National Health Priority Areas: proportion of the SA population with current, confirmed asthma, by area of residence prevalence of diabetes, by area of residence these charts demonstrate the upward trend in both areas generally higher figures are reported for country compared to metropolitan residence

16 SA Health Omnibus Surveys 1992 – 1999 Proportion with current, confirmed asthma

17 SA Health Omnibus Surveys 1991 – 1999 Prevalence of diabetes

18 NSW Health Survey 1997 The following slides provide some examples of data that have been collected in the NSW Health Survey 1997: Overweight/obesity Physical activity Private health insurance The following slides present the data by: sex, age group, Health Area x sex (age-adjusted prevalence ratios)

36 Victorian Population Health Survey 1999 The following charts show the use of personal protective equipment in sport and the understanding of disease inheritance: The minority of participants are using protective equipment with less than 20% use of protective equipment in netball and basketball Barely 50% use of protective equipment in soccer, indoor cricket and Australian rules football These data provide a State-wide baseline for the evaluation of policies to enhance the use of personal protective equipment Sets the direction for future health promotion messages to ensure they are appropriately targeted campaigns The extent of public knowledge about the inheritance of particular diseases is important in controlling the disease.
