Item Cervical abnormalities are more common among Indigenous than other Australian women: a retrospective record-linkage study, 2000-2011.(2016-04-22) Whop L.J.; Baade P.; Garvey G.; Cunningham J.; Brotherton J.M.L.; Lokuge K.; Valery P.C.; O'Connell D.L.; Canfell K.; Diaz A.; Roder D.; Gertig D.M.; Moore S.P.; Condon J.R.Indigenous Australian women have much higher incidence of cervical cancer compared to non-Indigenous women. Despite an organised cervical screening program introduced 25 years ago, a paucity of Indigenous-identified data in Pap Smear Registers remains. Prevalence of cervical abnormalities detected among the screened Indigenous population has not previously been reported. We conducted a retrospective cohort study of populationbased linked health records for 1,334,795 female Queensland residents aged 20-69 years who had one or more Pap smears during 2000-2011; from linked hospital records 23,483 were identified as Indigenous. Prevalence was calculated separately for Indigenous and non-Indigenous women, for cytology-detected low-grade (cLGA) and highgrade abnormalities (cHGA), and histologically confirmed high-grade abnormalities (hHGA). Odds ratios (OR) were estimated from logistic regression analysis. In 2010-2011 the prevalence of hHGA among Indigenous women (16.6 per 1000 women screened, 95% confidence interval [CI] 14.6-18.9) was twice that of non-Indigenous women (7.5 per 1000 women screened, CI 7.3-7.7). Adjusted for age, area-level disadvantage and place of residence, Indigenous women had higher prevalence of cLGA (OR 1.4, CI 1.3-1.4), cHGA (OR 2.2, CI 2.1-2.3) and hHGA (OR 2.0, CI 1.9-2.1). Our findings show that Indigenous women recorded on the Pap Smear Register have much higher prevalence for cLGA, cHGA and hHGA compared to non-Indigenous women. The renewed cervical screening program, to be implemented in 2017, offers opportunities to reduce the burden of abnormalities and invasive cancer among Indigenous women and address long-standing data deficiencies.Copyright © 2016 Whop et al.

Design, setting, participants: Population-based retrospective cohort analysis of linked data from the Queensland Pap Smear Register (PSR), the Queensland Hospital Admitted Patient Data Collection, and the Queensland Cancer Registry. 34 980 women aged 20e68 years (including 1592 Indigenous women) with their first HGA Pap smear result recorded on the PSR (index smear) during 2000e2009 were included and followed to the end of 2010. Main Outcome Measure(s): Time from the index smear to clinical investigation (histology test or cancer diagnosis date), censored at 12 months. Result(s): The proportion of women who had a clinical investigation within 2 months of a HGA finding was lower for Indigenous (34.1%; 95% CI, 31.8e36.4%) than for non-Indigenous women (46.5%; 95% CI, 46.0e47.0%; unadjusted incidence rate ratio [IRR], 0.65; 95% CI, 0.60e0.71). This difference remained after adjusting for place of residence, area-level disadvantage, and age group (adjusted IRR, 0.74; 95% CI, 0.68e0.81). However, Indigenous women who had not been followed up within 2months were subsequently more likely to have a clinical investigation than non-Indigenous women (adjusted IRR for 2e4 month interval, 1.21; 95% CI, 1.08e1.36); by 6 months, a similar proportion of Indigenous (62.2%; 95% CI, 59.8e64.6%) and non-Indigenous women (62.8%; 95% CI, 62.2e63.3%) had been followed up. Conclusion(s): Prompt follow-up after a HGA Pap smear finding needs to improve for Indigenous women. Nevertheless, slow follow-up is a smaller contributor to their higher cervical cancer incidence and mortality than their lower participation in cervical screening.Copyright ©2017 AMPCo Pty Ltd.
