Cervical Cancer Screening Among Immigrant and Refugee Women: Scoping-Review and Directions for Future Research

Adherence and Correlates of Cervical Cancer Screening Among East African Immigrant Women in Washington State

INTRODUCTION

Cervical cancer screening (CCS) among East African immigrants (EAI) in the USA is under explored. This study aimed to investigate adherence to CCS and its correlates among EAI.

METHODS

We identified 1664 EAI women (25-65 years) with ≥ 1 primary care clinic visit(s) between 2017 and 2018, using University of Washington (UW) Medicine electronic health record data. CCS adherence was defined as Pap testing within 3 years or human papillomavirus/Pap co-testing within 5 years. We used Poisson regression with robust standard errors to cross-sectionally estimate associations with correlates of adherence. Twelve-month screening uptake was also evaluated among overdue women.

RESULTS

CCS adherence was 63%. Factors associated with higher adherence included older age (adjusted prevalence ratios [APRs]:1.47:95%CI:1.14-1.90, 1.38:95%CI:1.05-1.80, respectively, for ages 30-39 and 40-49 vs 25-29 years), longer duration of care at UW Medicine (APR:1.22:95%CI:1.03-1.45, comparing > 10 vs < 5 years), higher visit frequency (APR:1.23:95%CI:1.04-1.44, 1.46:95%CI:1.24-1.72, respectively, for 3-5 and ≥ 6 vs 1-2 visits), index visit in an obstetrics-gynecology clinic (APR:1.26:95%CI:1.03-1.55, vs family practice), having an assigned primary care provider (APR:1.35: 95%CI:1.02-1.79), breast cancer screening adherence (APR:1.66: 95%CI:1.27-2.17), and colorectal cancer screening adherence (APR:1.59:95%CI:1.24-2.03). Low BMI was associated with lower adherence (APR:0.50:95%CI:0.26-0.96, comparing < 18.5 kg/m2 vs 18.5-24.9 kg/m2). Among 608 (37%) overdue women, 9% were screened in the subsequent 12 months. Having commercial health insurance vs Medicare/Medicaid was associated with higher uptake (adjusted risk ratio:2.44:95%CI:1.15-5.18).

CONCLUSION

CCS adherence among EAI was lower than the national average of 80%. Interventions focused on increasing healthcare access/utilization or leveraging healthcare encounters to address barriers could increase CCS in EAIs.

Exploring the barriers to Pap smear test compliance: A qualitative study for improving cervical cancer screening in the primary health care

Background

Cervical cancer in Iran ranks as the fourth most frequent cancer among women. Pap smear (PS) is the best standard for detecting cervical cancer, but many people, even healthcare providers (HCPs), do not maintain it. HCPs play a critical role in promoting PS uptake. The purpose of the study was to explore barriers to cervical cancer PS screening compliance from the HCPs' perspective.

Methods

The present qualitative content analysis was conducted through semi-structured in-depth interviews. A total of 28 HCPs were interviewed between July and August 2020. A diverse sample of HCPs was selected using purposive sampling. Data analysis was based on the five steps proposed by Graneheim and Lundman. MAXQDA (2020) was used for data analyzing.

Results

Ten key sub-categories were identified and organized into three categories: individual, environmental, and socio-cultural factors. The sub-categories included inadequate risk perception, inappropriate attitude, low commitment, emotional factors, low priority over health, requirements and consequences of the test, deficiencies of health centers, organizational factors, traditions and religious believes.

Conclusion

HCPs face multiple barriers for PS. Exploring and decreasing barriers of PS in HCPs may increase compliance in them and their clients because they play an influential role in instructing and persuading women to take the PS. There is need to explore these barriers and identify possible interventions to change them. Insights from this study are useful for developing policies around national PS programs, too.

Exploring factors associated with preferences for human papillomavirus (HPV) self-sampling among racially- and ethnically-diverse women in Minnesota: A cross-sectional study

Pap tests are still underutilized by minority women due to limited awareness of cervical cancer screening (CCS), inadequate health care access, and cultural or religious beliefs. Human papillomavirus (HPV) self-sampling, a new CCS tool, has demonstrated potential to overcome some of these barriers. In 2021, women aged 30-65 years old were recruited across Minnesota to complete an online survey. The survey assessed five outcome measures related to HPV self-sampling: (1) awareness of test; (2) self-efficacy to conduct test; (3) location preference of test (clinic vs. home); 4) collector preference (self vs. clinician); and (5) preference of CCS strategy (HPV self-sampling vs. Pap test). Modified Poisson regressions tested associations between sociodemographic variables and outcomes. A total of 420 women completed the survey, of which 32.4% identified as Non-Hispanic white, 22.2% as Hispanic, 12.6% as Black/African-American, 28.3% as Asian, 1.9% as American Indian/Alaskan Native, and 1.4% as more than two races. Few women had heard of HPV self-sampling (6.5%), but a majority reported high self-efficacy to perform self-sampling (75.3%). Women also reported higher preferences for completing an HPV test in the clinic (52.2%) and for performing a self-collected HPV test themselves (58.7%), yet would choose a traditional Pap test over HPV self-sampling (56.0%). The low level of HPV self-sampling awareness, across all racial/ethnic groups, suggests a strong opportunity to promote widespread educational efforts around this new tool. Future HPV self-sampling research efforts should examine educational interventions targeted at healthcare providers to educate and encourage women on the importance of self-collection options.

Health care personnel's perspectives on human papillomavirus (HPV) self-sampling for cervical cancer screening: a pre-implementation, qualitative study

BACKGROUND

Persistent infection with high-risk human papillomavirus (hrHPV) types is a well-documented cause of cervical cancer. Since the implementation of cervical cancer screening methods (e.g., Pap tests), cervical cancer rates have declined. However, Pap tests are still unacceptable to many women and require complex infrastructure and training. Self-sampling techniques for collecting HPV specimens (or "HPV self-sampling") have been proposed as a possible alternative to overcome these barriers. The objective of this study was to capture perspectives from health care personnel (providers, leaders, and clinic staff) across primary care systems on the potential implementation of an HPV self-sampling practice.

METHODS

Between May and July 2021, a study invitation was emailed to various health care professional networks across the Midwest, including a snowball sampling of these networks. Eligible participants were invited to a 45-60-min Zoom-recorded interview session and asked to complete a pre-interview survey. The survey collected sociodemographics on age, occupation, level of educational attainment, race/ethnicity, gender, and awareness of HPV self-sampling. The semi-structured interview was guided by the Consolidated Framework for Implementation Research and asked participants about their views on HPV self-sampling and its potential implementation. All interviews were audio-recorded, transcribed, and analyzed using NVivo 12.

RESULTS

Key informant interviews were conducted with thirty health care personnel-13 health care providers, 6 clinic staff, and 11 health care leaders-from various health care systems. Most participants had not heard of HPV self-sampling but reported a general enthusiasm for wanting to implement it as an alternative cervical cancer screening tool. Possible barriers to implementation were knowledge of clinical evidence and ease of integration into existing clinic workflows. Potential facilitators included the previous adoption of similar self-sampling tools (e.g., stool-based testing kits) and key decision-makers.

CONCLUSION

Although support for HPV self-sampling is growing, its intervention's characteristics (e.g., advantages, adaptability) and the evidence of its clinical efficacy and feasibility need to be better disseminated across US primary care settings and its potential adopters. Future research is also needed to support the integration of HPV self-sampling within various delivery modalities (mail-based vs. clinic-based).

Non-attendance in cervical cancer screening among migrant women in Portugal: A cross-sectional study

Objectives:

Cervical cancer has a high mortality rate among women worldwide. Although cervical cancer screening (CCS) is an effective strategy in reducing mortality of the disease, inequalities in accessing screening exist, particularly among migrant women. This study aims to characterize migrant women’s participation in CCS and determine factors associated with non-attendance to CCS.

Methods:

A cross-sectional study based on a web-based survey targeting adult migrant women living in Portugal was conducted. Prevalence of non-attendance to CCS was examined, and its associations with socioeconomic, migration-related, and health-related factors were determined using adjusted logistic regression models.

Results:

A total of 1100 migrant women were included in the study. Prevalence of CCS non-attendance was 24.5%. CCS non-attendance was associated with younger age, being born in Africa or Asia, being single/divorced/widowed, never having had a GP appointment in Portugal and not having regular gynecology appointments. Being born in South and Central America, shorter length of stay in Portugal, having had HPV vaccination, and not having children are associated with CCS attendance.

Conclusion:

These findings point out that an important percentage of migrant women do not attend CCS. Strategies to increase participation should be developed, considering the inequalities identified and designed to target the specific needs of migrant women to improve their CCS attendance and increase cervical cancer prevention.

Human Papillomavirus Vaccination and Pap Smear Rates Among Burmese Refugee Girls in a Healthcare System in Omaha, Nebraska

While human papilloma virus (HPV) vaccinations and Pap smear screenings are known to improve the survival rates and incidence of cervical cancer, refugee populations have traditionally been disadvantaged within this arena. Due to past and recent political issues in Myanmar, Burmese refugee women in Nebraska may be at particular risk due to their increasing numbers. This study examined 65 female Burmese refugees who were candidates for HPV vaccinations and 106 female Burmese refugees who could have received Pap smear screenings between 2010 and 2020. Of the 65 patients aged 11-26, 49.2% initiated the HPV vaccine series and 30.8% completed the series. In patients aged 13-17, 86.4% initiated the vaccine series and 54.6% completed the series. Of the 106 patients over 18 years of age, 32.1% had a Pap smear within the last 3 years. The need to improve HPV vaccine and Pap smear rates in refugee populations is clear. While focusing on the designated refugee exam may have improved HPV vaccine rates, it is important to examine gaps in knowledge with regards to attitudes surrounding HPV vaccines and Pap smears within the Burmese refugee population.

Health Inequity in Cervical Cancer Control Among Refugee Women in the United States by Country of Origin

Purpose: To describe cervical cancer control practices from common countries of origin for women who resettle in the United States as refugees to highlight this persistent health inequity.

Methods: Describe presence/type of national cervical cancer screening program, screening coverage percentage, and human papillomavirus (HPV) vaccination program presence and coverage.

Results: Nine of 15 included countries screen opportunistically. Most do not use high-performing tests, and estimates of screening coverage were limited. Only one country offers HPV vaccination.

Conclusion: Countries of origin for refugee women may lack effective national cervical cancer control programs. To meet the World Health Organization (WHO)'s call to eliminate cervical cancer by 2030, focus on culturally tailored education, and continued research are paramount.
