Abstract
BACKGROUND Cisgender women with HIV experience an elevated risk of cervical cancer compared with HIV-negative women, but this cancer can be prevented through regular cervical cancer screening. Our study objective was to measure adherence to current national cervical cancer screening guidelines among women with HIV in 3 Canadian provinces and identify factors associated with delays. METHODS We conducted a cross-sectional study using the baseline questionnaire of the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS). Participants were recruited through clinics, peers and community organizations in British Columbia, Ontario and Quebec. Women were eligible for inclusion if they were cisgender female with HIV, aged 21-70 years, and never had cervicectomy/hysterectomy. RESULTS Of 1189 eligible participants, 815 (68.5%) had received cervical cancer screening less than 1 year ago (i.e., as recommended), 211 (17.7%) 1-3 years ago (i.e., moderate delay) and 163 (13.7%) at least 3 years ago or never (i.e., long delay). Overall, 309 (26.0%) had never discussed the need for a Papanicolaou smear with a nurse/doctor. Factors associated with a long delay were living in Ontario (adjusted odds ratio [OR] 2.51, 95% confidence interval [CI] 1.29-4.88) or Quebec (adjusted OR 3.70, 95% CI 1.79-7.67) (v. BC), being sexually inactive in the past 6 months (adjusted OR 2.02, 95% CI 1.25-3.25), having unknown or < 200 cells/mm3 CD4 counts (adjusted OR 1.78, 95% CI 1.11-2.85) and having a male HIV care provider (adjusted OR 2.15, 95% CI 1.36-3.42). INTERPRETATION Over one-third of women reported cervical cancer screening delays, and one-quarter had never discussed cervical cancer screening recommendations with a health care provider. Additional efforts are needed to improve women's and health care providers' awareness of cervical cancer screening recommendations, particularly among women who are sexually inactive, who are immunosuppressed and who have male HIV care providers.

Cervical cancer screening uptake among HIV-positive women in Ontario, Canada: A population-based retrospective cohort study. Prev Med 2018; 107:14-20. [PMID: 29197533 DOI: 10.1016/j.ypmed.2017.11.023] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2017] [Revised: 11/16/2017] [Accepted: 11/26/2017] [Indexed: 10/18/2022]
Abstract
Cervical cancer caused by oncogenic types of the human papillomavirus (HPV) is of concern among HIV-positive women due to impairment of immune responses required to control HPV infection. Our objectives were to describe patterns of cervical cancer screening using Pap cytology testing among HIV-positive women in Ontario, Canada from 2008 to 2013 and to identify factors associated with adequate screening. We conducted a retrospective, population-based cohort study among screen-eligible HIV-positive women using provincial administrative health data. We estimated annual proportions tested and reported these with 95% confidence intervals (CI). Next, using person-years as the unit of analysis, we identified factors associated with annual Pap testing using log-binomial regression. A total of 2271 women were followed over 10,697 person-years. In 2008, 34.0% (95%CI 31.1-37.0%) had a Pap test. By 2013, the proportion of HIV-positive women tested was 25.9% (95%CI 23.6-28.2%). Women who were most likely to undergo testing were younger, were immigrants from countries with generalized HIV epidemics, lived in the highest income neighbourhoods, had a female primary care physician, had two or more encounters per year with an infectious disease or internal medicine specialist, and had greater comorbidity. Nearly three in four HIV-positive women were under-screened despite all having universal insurance for medically-necessary services. Annual Pap testing decreased following the 2011-2013 release of new guidelines for a lengthened screen interval for average risk women and a billing disincentive. Clinic-based intervention such as physician alerts or reminders may be needed to improve screening coverage among HIV-positive women.
