Aged Care Residents Influenza Vaccination Survey, November 2004 -->
B. User Requirements, Survey Objectives, and Budget
B1 Purpose of survey
Why do you need to conduct a survey? (B1)
Note. Refers to the underlying information requirements that the survey is intended to address. For example, what problems the agency is trying to solve? What decisions need to be made? What specific policies or actions are being determined or assessed? Should detail who requires the information. Survey objectives should be included in "B2" below.
The main Adult Vaccination Survey seeks to estimate the proportion of the population aged 65 years and over vaccinated against influenza and pneumococcus, in order to aid the Australian Government’s review of its immunisation programs.
That survey is carried out by computer assisted telephone interview (CATI). By its nature, CATI excludes residential facilities and their residents (approximately 150,000).
We want to ask questions of Directors of Nursing so that we can use the results to refine the general population estimates. The survey will produce an estimate of vaccine coverage in residential aged care facilities.

How will the survey outputs meet the needs specified in B1? What are the target RSEs for the survey? (B2)
Note. Should include a brief overview of the main topics the survey will cover. If applicable, provides details of any constraints including: fixed costs, fixed sample size, fixed accuracy (eg target RSEs, Confidence Intervals), etc.
Directors of Nursing will be asked to provide numbers of residents (65 years old or more), their vaccination status and how many paid for the vaccine. These estimates will be weighted to the whole residential population and used to calculate adjustments to the main survey results.

The survey will be conducted ‘in house’ using AIHW staff to conduct a short (5 main questions) telephone interview. With an expected response rate of around 75% we hope to achieve 200 completed interviews of residential facilities (nursing home and hostels only) with an expected relative standard error of around 2.8% (~86.7% +/- 2.4%).
The main constraints on the accuracy of our results will be the ability of the Directors of Nursing to estimate vaccination levels. In some cases, the facility’s policy will help but in others we will settle for an educated guess.
We will be further constrained by the availability of staff in the facilities. We plan to call between 11am and noon and between 2pm and 3pm, avoiding meals and shift changes.
What is the timetable for the survey? (B3)
Note. Should include: testing, the date questionnaires are printed or finalised, the date data collection commences, the date data collection finishes, and when results will be available. SCH approval for the survey is to be obtained before data collection commences.
Fieldwork for the main survey will be completed in October 2004. We hope to complete the residential aged care facilities survey in the same period.

The questionnaire used for the 2003 survey is attached. Results will be available with publication of the main survey results in early 2005.
