  7. Why an online survey? Young cohort Available email addresses 66% of South Australians had access to internet at home* *2009 Australian Bureau of Statistics

  8. Non-Responder Follow-up • After 1 week: • reminder email (n= 36) • At 2 weeks: • reminder phone call (n=14)

  9. Online vs Paper-Based • A recent paper based cohort study selected (n=328) • Cohort study • Multi-day camp situation • Timeliness and response rate of online compared with paper-based

  10. Online Questionnaire 35% (9% in first hour) (n= 31 of 89) Paper Based Method 0% (n= 0 of 328) Timeliness: 24 Hours

  11. Online Questionnaire 65% (n=58 of 89) Paper Based Method 16% (n= 52 of 328) Timeliness: Day 5

  12. Online Questionnaire 78% (n= 69 of 89) Paper Based Method 50% (n= 164 of 328) Timeliness: Day10

  13. Online Questionnaire 83% (n=74 of 89) Paper Based Method 75% (n=246 of 328) Overall Response Rate

  14. Online Questionnaire 14 days (analysis at day 3) Paper Based Method 2 months Timeliness: Participant Survey Completion

  15. Day1: 42% (n=31) Day 3: initial analysis Day 7: 92% (n=68) Email Reminder Phone Reminder

  16. Online Questionnaire Minimal data entry necessary 2 of 74 manually entered Data Cleaning Paper Based Method Manually entered Data Entry

  17. Importance of Timeliness? • Higher quality information collected • Rapid public health action

  18. Limitations Shared email accounts Survey completeness for children 24 hour clock issues Third party data storage Comparison outbreak much larger

  19. Conclusion Easy tool to use Cost efficient Time efficient Resource efficient However, offsite data storage needs to be addressed

  20. Acknowledgements The outbreak investigation team Field Supervisor: Dr Jane Raupach ANU Supervisor: Michelle McPherson SA Health Australian Department of Health and Ageing for funding the MAE program 2009 and 2010 Australian MAE cohorts
