THE OUTPUT STRATEGY - WORK PROGRAM AND TIMETABLE

The AHS is a large and complex survey to collect, process and analyse. To date the collection phase has been planned, consulted upon and has commenced its execution in the field for the general community. Enumeration of the Aboriginal and Torres Strait Islander community commenced in April 2012. The high level release timetable and its elements are described below.

Processing approach

The AHS will be conducted in two parts:

  • General population (March 2011 - June 2012); and
  • Aboriginal and Torres Strait Islander population (April 2012 - June 2013).

These collection timetables plus the subsequent processing, weighting, and analysis time will determine when data will become available. It is intended to progressively process data from interviews and biomedical tests, however, the completion of some data processing elements will be dependent on the finalisation of others and therefore completion of processing around the later elements will be the time limiting factor. The ABS will examine interim data for quality assurance purposes, begin to test the interim data against benchmarks, and to identify data elements where either confidentiality actions might be required or where relative standard errors might be larger and require some form of treatment.

It should be recognised that some data collected at interview will be relatively straight forward and not require further management post interview, however other data elements will require more detailed examination, cleaning and post processing. This latter point is particularly relevant for the nutrition components of the survey where food and supplement intakes will need to be combined with a food composition database to determine nutrient intakes. This nutrition data management will be a multi-step process that will engage FSANZ in the analysis and coding of data and development of a survey specific food and supplement composition database.

Initial and subsequent data releases

It is the intent of the ABS to process the AHS data and create base data files from which analysis can proceed in a staged manner, reflecting the different data collection and processing timetables for the different components of the survey. This will allow for data to be released in the most timely manner.

For example, information on some risk factors will be collected in the National Health Survey (NHS) component, as well as in the National Nutrition and Physical Activity Survey (NNPAS) conducted later in the timetable (for example, smoking - see 'AHS Core' in Diagram 1). As there will be sufficient sample from the NHS component to report on these risk factors, estimates will be produced as part of the 'conditions and risk factors release'. When the NNPAS component is completed, a revised estimate will be produced based on the larger sample in the 'conditions and risk factors revised release'.

The key strategies for managing the information output timetable are to:
  • identify the key data elements required for processing to meet the information requirements needed early in the output timetable;
  • provide data as it becomes available through a staged release mechanism; and
  • communicate an output timetable to users for various products and the focus of the products so that users might influence their priority and anticipate their availability.

Timetable

The following broad timetable is envisaged, however the finalisation of this timetable cannot occur until an assessment of the data quality, response rates and confirmation of user priorities has occurred.

Basic CURF releases and data access toolsSecond half of 2013Unit record data and Survey Table BuilderMultiple CURFs will be released that combine the common elements of the AHS (final structures to be finalised)



The approach for the outputs for the Aboriginal and Torres Strait Islander components (starting October 2013) are similar in nature to that of the general population survey, however careful consideration will be made regarding cultural sensitivities, ensuring robust statistical analysis and the use of Aboriginal and Torres Strait Islander advisors in planning the release strategy.

CONSULTATION TIMETABLE

The proposed timetable for stakeholder consultation on output from the AHS is as follows:
