    ABSTRACT: To compare the use of two alternative population-based denominators in calculating HPV vaccine coverage in Australia by age groups, jurisdiction and remoteness areas. Data from the National HPV Vaccination Program Register (NHVPR) were analysed at Local Government Area (LGA) level, by state/territory and by the Australian Standard Geographical Classification Remoteness Structure. The proportion of females vaccinated was calculated using both the ABS ERP and Medicare enrolments as the denominator. HPV vaccine coverage estimates were slightly higher using Medicare enrolments than using the ABS estimated resident population nationally (70.8% compared with 70.4% for 12 to 17-year-old females, and 33.3% compared with 31.9% for 18 to 26-year-old females, respectively.) The greatest differences in coverage were found in the remote areas of Australia. There is minimal difference between coverage estimates made using the two denominators except in Remote and Very Remote areas where small residential populations make interpretation more difficult. Adoption of Medicare enrolments for the denominator in the ongoing program would make minimal, if any, difference to routine coverage estimates. © 2015 Public Health Association of Australia.

    ABSTRACT: Objective: To determine whether HPV vaccine coverage in 12-13-year-olds varies by geographical area, remoteness and ecological level indicators of socioeconomic status (SES). Method: Data from the National HPV Vaccination Program Register (NHVPR) were analysed at Statistical Local Area (SLA) level, by the Index of Relative Disadvantage (IRSD) and the Australian Standard Geographical Classification Remoteness Structure. Results: Nationally, 73% of females aged 12-13 years in 2007 were fully vaccinated against HPV. Coverage in low SES areas (71.5%) was 4.1 percentage points lower than coverage in high SES areas (75.6%). Uptake of the first two doses was higher in the very remote parts of Australia (dose 1 - 88.5%, dose 2 - 81.8%) than in major cities (dose 1 - 83.4%, dose 2 - 80.2%), but not for dose 3 where coverage in major cities was 3% higher (73.6% versus 71.4%). Conclusion: Notifications of HPV vaccine doses delivered to females aged 12-13 through schools suggest a high and relatively equal uptake across socioeconomic groups. Females in remote regions have the highest uptake of dose 1 but are least likely to complete the course. This may be due to particular challenges in vaccine delivery to residents of remote areas.

    ABSTRACT: We analysed human papillomavirus (HPV) vaccination coverage from the 2007-2009 catch-up program for women aged 18-26 years by Division of General Practice (DGP), alongside a survey about under-notification. Coverage rates were calculated from the National HPV Vaccination Program Register. An online survey of immunisation coordinators in DGP assessed under-notification. HPV vaccine coverage by DGPs varied greatly: dose 1, 22-70%; dose 2, 13-60%; dose 3, 7-49%. Most coordinators (38/52, 66%) believed that more than 80% of practices notified the register. Perceived notification barriers included being busy, not knowing how to notify, not obtaining consent, insufficient remuneration and delay in register establishment. DGP coverage varied widely. Process barriers (time and resource limitations) probably contributed to under-notification, with informational barriers (unaware how to notify) and motivational barriers (not worth the effort) secondary to this. Differences in reported coverage between DGPs and states reflect both differences in notification rates and underlying HPV vaccine coverage.
