Contextual factors associated with uptake of breast and cervical cancer screening: A systematic review of the literature

Factors associated with deferral or non-performance of an organized breast cancer screening program during the COVID-19 pandemic in France

BACKGROUND

Delays in detection and treatment of breast cancer can lead to increased mortality. To date, participation in organized breast cancer screenings (OBCS) has been suboptimal worldwide. The objective of this study was to investigate the factors associated with deferral or non-performance of mammography during the COVID-19 pandemic for women who had previously participated in OBCS.

METHODS

A retrospective observational study was conducted on a cohort of 6282 women from the Aube Department of France, who were invited to an OBCS in 2020. Participants were divided into women who promptly underwent screening after receiving an invitation (between 22 and 25 months elapsed since the last mammogram), women who underwent late screening (≥26 months since the last mammogram), and those who were never screened. Data were collected from a self-reported questionnaire. Comparative and multivariable analyses modeling the probability of each type of attendance were performed using these data.

RESULTS

In total, 2301 women (aged 50-74 years) returned a valid questionnaire. Compared to women who promptly underwent mammography, non- and late-screening participants were younger, had less frequent gynecological follow-up and a less frequent history of colorectal cancer screening. Women with higher education status and those residing in socially disadvantaged areas were more likely to attend late.

CONCLUSION

The absence of regular gynecological follow-up and the absence of colorectal cancer screening were significant factors associated with deferral of or non-attendance at OBCS.

Coverage and Socioeconomic Inequalities in Cervical Cancer Screening in Low- and Middle-Income Countries Between 2010 and 2019

PURPOSE

Cervical cancer screening is vital in addressing the global burden of cervical cancer. In this study, we describe the coverage and socioeconomic inequalities in the coverage of cervical cancer screening in low- and middle-income countries (LMICs).

METHODS

We analyzed data from the women's recode files of the Demographic and Health Surveys conducted in LMICs from 2010 to 2019 with variables on cervical cancer screening. We included women 21 years or older and determined the proportion of women who were screened for cervical cancer by age categories, wealth quintile, type of place of residence, level of education, and marital status. Socioeconomic inequality was measured using the concentration index (CIX) and the slope index of inequality (SII).

RESULTS

A total of 269,506 women from 20 surveys in 16 countries were included in the survey. Generally, there was a low coverage of screening, with lower rates among women age 21-24 years, living in rural areas, in the poorest wealth quintile, with no formal education, and who have never been in union with or lived with a man. The CIX and SII values for screening for cervical cancer were positive (pro-rich) for all the countries except Tajikistan in 2012 where they were negative (pro-poor).

CONCLUSION

The coverage of cervical cancer screening was low in LMICs with variations by the quintile of wealth (pro-rich) and type of place of residence (pro-urban). To achieve the desired impact of cervical cancer screening services in LMICs, the coverage of cervical cancer screening programs must include women irrespective of the type of place and wealth quintiles.

Determinants of routine cervical screening participation in underserved women: a qualitative systematic review

OBJECTIVE

Routine, population-wide cervical screening programmes reduce cervical cancer incidence and mortality. However, socioeconomically deprived communities and ethnic minority groups typically have lower uptake in comparison to the general population and thus are described as 'underserved.' A systematic qualitative literature review was conducted to identify relevant determinants of participation for these groups.

METHODS

Online databases were searched for relevant literature from countries with well-established, call-recall screening programmes. Overall, 24 articles were eligible for inclusion. Data was synthesized via Framework synthesis. Dahlgren & Whitehead's social model of health was used as a broad a priori coding framework.

RESULTS

Participation was influenced by determinants at multiple levels. Overall, patient-provider relationships and peer support facilitated engagement. Cultural disparities, past healthcare experience and practical barriers hindered service access and exacerbated negative thoughts, feelings and attitudes towards participation. Complex interrelationships between determinants suggest barriers have a cumulative effect on screening participation.

CONCLUSIONS

These findings present a framework of psychosocial determinants of cervical screening uptake in underserved women and emphasise the role of policy makers and practitioners in reducing structural barriers to screening services. Additional work, exploring the experience of those living within socioeconomically disadvantaged areas, is needed to strengthen understanding in this area.

Women's perceptions and preferences for cervical cancer screening in light of updated guidelines

BACKGROUND

Updated risk-based guidelines for cervical cancer screening (CCS) allow for individualized screening that minimizes unnecessary testing. However, these guidelines are complex and may not be easily understandable to patients.

PURPOSE

To describe women's perceptions and preferences about CCS in light of recent guideline changes.

METHODOLOGY

This qualitative study conducted in February 2020 used online, text-based focus groups with a sample of US women ( n = 49) ages 27-45. After participants completed a short demographic survey, an experienced moderator used a semistructured guide to solicit participants' perceptions of routine gynecologic care and CCS. We summarized survey data using descriptive statistics. Two authors analyzed transcripts using conventional content analysis and met with other team members to resolve discrepancies and determine final themes.

RESULTS

Most participants were non-Hispanic White (65%), had health insurance (90%), and reported having a routine gynecologic examination in the past year (70%). We identified four common themes: (1) low perceived risk of human papillomavirus (HPV) coupled with low knowledge about HPV as a causative factor for cervical cancer, (2) confusion about-and mistrust of-recent individual risk-based guidelines that determine the indicated timing and type of CCS test (Pap or HPV testing), (3) mixed opinions about performing a self-swab for HPV testing, and (4) conflicting perceptions of trust toward providers and the health care industry.

CONCLUSIONS

Findings highlight women's uncertainty and hesitancy about updated CCS guidelines.

IMPLICATIONS

Provider-patient communication strategies should consider women's gaps in knowledge about HPV, include the rationale for guidelines and types of tests, and build trust between patients and providers.

Factors associated with breast cancer screening services use among women in the United States: An application of the Andersen's Behavioral Model of Health Services Use

This study applied Andersen's Behavioral Model of Health Services Use to examine predisposing, enabling, and need factors associated with adherence to the United States Preventive Services Task Force (USPSTF) guidelines for breast cancer screening (BCS). Multivariable logistic regression was used to determine factors of BCS services utilization among 5484 women aged 50-74 from the 2019 National Health Interview Survey. Predisposing factors significantly associated with use of BCS services were: being a Black (odds-ratios [OR]:1.49; 95% confidence interval [CI]:1.14-1.95) or a Hispanic woman (OR:2.25; CI:1.62-3.12); being married/partnered (OR:1.32, CI:1.12-1.55); having more than a bachelor's degree (OR: 1.62; CI:1.14-2.30); and living in rural areas (OR:0.72; CI:0.59-0.92). Enabling factors were: poverty level [≤138% federal poverty level (FPL) (OR:0.74; CI:0.56-0.97), >138-250% FPL (OR:0.77; CI:0.61-0.97), and > 250-400% FPL (OR:0.77; CI:0.63-0.94)]; being uninsured (OR:0.29; CI:0.21-0.40); having a usual source of care at a physician office (OR:7.27; CI:4.99-10.57) or other healthcare facilities (OR:4.12; CI:2.68-6.33); and previous breast examination by a healthcare professional (OR:2.10; CI:1.68-2.64). Need factors were: having fair/poor health (OR:0.76; CI:0.59-0.97) and being underweight (OR:0.46; CI:0.30-0.71). Disparities in BCS services utilization by Black and Hispanic women have been reduced. Disparities still exist for uninsured and financially restrained women living in rural areas. Addressing disparities in BCS uptake and improving adherence to USPSTF guidelines may require revamping policies that address disparities in enabling resources, such as health insurance, income, and health care access.

Factors affecting women's participation in mammography screening in Nordic countries: A systematic review

INTRODUCTION

Mammography screening programs have been implemented in European countries as prevention tools aimed at reducing breast cancer mortality through early detection in asymptomatic women. Nordic countries (Denmark, Finland, Iceland, Norway, Sweden, the Faroe Islands, and Greenland) demonstrated high participation rates; however, breast cancer mortality could be limited by further optimizing screening. This review aimed to explore factors that affect women's participation in mammography screening in Nordic countries.

METHOD

A systematic review of segregated mixed research synthesis using a deductive approach was conducted. The following databases and platforms were searched to identify relevant studies: CINAHL with Full Text (EBSCOHost), MEDLINE (EBSCOHost), PsycInfo (ProQuest), Scopus (Elsevier) and Web of Science Core Collection (SCI-EXPANDED, SSCI, A&HCI, CPCI-S, CPCI-SSH, and ESCI). The Critical Appraisal Skills Program was used for quality assessment. The Health Promotion Model was applied to integrate findings from qualitative and qualitative research. All methodological steps followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

RESULTS

The final selection (16 articles) included studies from three Nordic countries: Denmark (four quantitative studies), Norway (one qualitative and four quantitative studies), and Sweden (three qualitative and seven quantitative studies). Sixty-three factors were identified as barriers, facilitators, or factors with no influence.

CONCLUSION

A substantial number of obtained factors, spread across a wide spectrum, describe (non-)participation in mammography screening as a versatile phenomenon.

IMPLICATIONS FOR PRACTICE

The findings of this review could benefit the mammography staff and providers regarding possible interventions aimed at improving screening participation rates.

Breast cancer: a randomized controlled trial assessing the effect of a decision aid on mammography screening uptake: study protocol

Introduction

Breast cancer (BC) is the primary cancer among women. The World Health Organization recommends a bilateral screening mammogram every 2 years for women aged 50 to 74 years. However, it has been shown that there is an absence of information about the benefits and risks of screening. Shared medical decision-making is important to ensure patients are involved in the decision process. Decision aids can facilitative this decision-making process. This article presents a protocol to evaluate the effect of a decision aid on participation rates in the French organized BC screening program.

Methods and analysis

Design and setting. The design is a 2 arm randomized controlled study, performed in the Pays de la Loire region (French West Coast). Randomization will be based on general medicine practices (Primary Care).

Participants

Women aged between 50 and 74 years, eligible for BC screening. In this region, there are 75000 women, and 2800 general practitioners eligible for recruitment.

Intervention

In the « Decision aid for organized cancer screening » arm, the intervention will distribute invitation letters to eligible women combined with the provision of decision aid to these women and their general practitioners and an incentive to implement shared medical decision-making. In the « Standard organized cancer screening » arm, only the screening invitation will be sent to eligible women.

Primary endpoint

BC screening participation rates will be assessed after an 18-month follow-up period.

Statistical analysis

In this non-inferiority trial, the percentage of women who are up-to-date with their screening at 18 months after the intervention will be compared across arms using a generalized mixed linear model.

Discussion

The research team expect to demonstrate that providing a better explanation of the benefits and risks of BC screening is not at odds with screening participation. The study results should help policy makers thinking about implementing shared medical decision-making within the framework of organized BC screening programs in the future.

Ethics and dissemination

On 6 December 2021, the protocol received a favorable opinion from the French Committee for the Protection of Persons (2021-A01583-38). This study is registered with ClinicalTrials.gov, number NCT05607849. (Version 1, November 7, 2022; https://www.clinicaltrials.gov/ct2/show/NCT05607849). The study findings will be used for publication in peer-reviewed scientific journals and presentations in scientific meetings.

Patient perspectives on cervical cancer screening interventions among underscreened women

BACKGROUND

Cervical cancer is highly preventable with regular screening, yet over 4,000 women die from it annually in the United States. Over half of new cervical cancer cases in the U.S. are attributable to insufficient screening.

METHODS

Participants were 23 low-income, uninsured or Medicaid-insured women in North Carolina who were overdue for cervical cancer screening according to national guidelines. Semi-structured interviews examined perspectives on barriers to cervical cancer screening and on interventions to reduce these barriers. We also elicited feedback on three proposed evidence-based interventions: one-on-one education, coupons to reduce out-of-pocket costs, and self-collection of samples for detection of high-risk human papillomavirus (HPV) infection, the primary cause of cervical cancer.

RESULTS

Reported barriers included high cost, inconvenient clinic hours, lack of provider recommendation, poor transportation, difficulty finding a provider, fear of pain, and low perceived need. Participants suggested interventions including reducing cost, improving convenience through community-based screening or extended clinic hours, strengthening provider recommendations, and providing one-on-one counseling and education outreach. HPV self-collection was most frequently selected as the "most helpful" of 3 proposed interventions (n = 11), followed by reducing out-of-pocket costs (n = 7) and one-on-one education (n = 5).

CONCLUSION

Cost was the most reported barrier to cervical cancer screening, although women experience multiple simultaneous barriers. Novel interventions such as HPV self-collection promise to reduce some, but not all, barriers to primary screening. Interventions that work on reducing multiple barriers, including obstacles to receiving follow-up care, may be most effective to prevent cervical cancer among these high-risk women.

Cervical cancer screening uptake: A randomized controlled trial assessing the effect of sending invitation letters to non-adherent women combined with sending their general practitioners a list of their non-adherent patients (study protocol)

Introduction

Cervical cancer (CC) is the fourth most common cancer among women. It can be cured if diagnosed at an early stage and treated promptly. The World Health Organization suggests that 70% of women should be screened with a high-performance test by the age of 35. This paper reports a protocol to assess the effect of two modalities of organized CC screening programmes on CC screening uptake.

Methods and analysis

Design and setting: The design involves a 3-arm randomized controlled study performed in a French geographic area on the west coast. A total of 1,395 general practitioners will be randomized, depending on their general practice surgeries. Participants: The design is based on a total of 94,393 women aged 40 to 65 years who are eligible for CC screening. Intervention: In the "optimized cancer screening" group, the intervention will combine sending invitation letters to non-adherent women with sending general practitioners (GPs) a list of their non-adherent patients. In the "standard cancer screening" group, the intervention will be limited to sending invitation letters to non-adherent women. In the "usual care" group, no letter will be sent either to women or to their GPs. Primary endpoint: CC screening test uptake will be assessed after a 6-month follow-up period. Statistical analysis: The percentage of women who are up-to-date with their screening at 6 months after the intervention will be compared across arms using a generalized mixed linear model.

Discussion

A large-scale randomized trial of this nature is unprecedented. The study will enable us to assess a strategy relying on GPs, identified as the coordinators in this screening strategy. The study results should help policy makers to implement organized CC screening programs in the future.

Ethics and dissemination

The study was approved was approved by the Ethics Committee of the National College of Teaching General practitioners (IRB00010804). It was recorded in ClinicalTrials.gov on the number NCT04689178 (28 December 2020). The study findings will be used for publication in peer-reviewed scientific journals and presentations in scientific meetings.

Barriers and Facilitators to Participation in Health Screening: an Umbrella Review Across Conditions

Screening is an essential prevention practice for a number of health conditions. However, screening coverage remains generally low. Studies that investigate determinants of screening participation are becoming more common, but oftentimes investigate screening for health conditions in an individualized rather than integrated fashion. In routine clinical practice, however, healthcare professionals are often confronted with situations in which several screening procedures are recommended for the same patient. The consideration of their common determinants may support a more integrated screening approach. The objectives of this umbrella review were therefore to examine: 1) the determinants (barriers and facilitators) that have been identified in relation to recommended health screening procedures; and 2) the modifiable determinants (in primary care) common across health conditions or specific to individual procedures. Results were presented through a narrative synthesis. PubMed, PsycInfo and Cochrane were searched up to January 2022. Systematic reviews reporting determinants of participation in health screening procedures with grade A or B recommendation according to the US Preventive Services Task Force were included. A total of 85 systematic reviews were included, most which contained both qualitative and quantitative studies on determinants that describe individual factors (961 occurrences), social factors (113 occurrences, healthcare professional factors (149 occurrences), health system factors (105 occurrences) and screening procedure factors (99 occurrences). The most studied screening procedures concerned cervical cancer/human papillomavirus (n = 33), breast cancer (n = 28), colorectal cancer (n = 25) and the human immunodeficiency virus (n = 12). Other conditions have been under-studied (e.g. cardiovascular problems, lung cancer, syphilis). The individual domain, including determinants such as knowledge, beliefs and emotions, was the most covered across health conditions. Healthcare professional's recommendations and the quality of patient-provider communication were identified to have a strong influence on screening participation in most conditions. The other three domains included determinants which were more specific to a condition or a population. Various determinants modifiable in primary care were found in the individual domain and in the health system, healthcare professional and screening procedure domains. Quality was assessed as low for most systematic reviews included. The identification of various modifiable determinants common across conditions highlights the potential of an integrated screening participation approach. Interventions may address common determinants in a broader person-centred framework within which tailoring to specific procedures or populations can be considered. This approach needs to be explored in intervention studies. The systematic review registration is PROSPERO CRD42019126709.

The experience of under-screened and never-screened participants using clinician-supported self-collection cervical screening within the Australian National Cervical Screening Program

Background:

Australia has had significant successes in the prevention of cervical cancer. However, there is considerable scope for improving screening participation. In December 2017, Australia shifted from cytology to a human papillomavirus–based screening program as part of the renewed National Cervical Screening Program. This provided the opportunity to introduce a clinician-supported self-collection cervical screening pathway, which allows screening participants aged 30 years or more and who are under-screened or never-screened to screen via a self-collected human papillomavirus test.

Objective:

This study aimed to explore screening participant experiences of a clinician-supported self-collection cervical screening pathway.

Methods:

Interviews (n = 45) were conducted with participants who had used the clinician-supported self-collection cervical screening pathway in the Australian National Cervical Screening Program between December 2017 and April 2019. Interviews were analyzed using template analysis.

Results:

Under-screened and never-screened participants reported a variety of interrelated barriers to cervical screening due to the nature of the test. For these participants, self-collection was a preferable way to perform screening as it overcame various barriers, was easy to use and promoted a sense of empowerment. Participants reported that the role of their practitioner was influential in their decision to undertake cervical screening, and that the support and information provided was a key factor in their experiences of the self-collection pathway.

Conclusion:

Findings support the use of a clinician-supported model of care, as an alternative screening modality in Australia’s National Cervical Screening Program. As more countries consider the move from a cytology to human papillomavirus–based cervical screening program, this model may assist in greater engagement of under-screened participants.

Contextual factors associated with cancer screening uptake: A systematic review of observational studies

We conducted a systematic review of a wide range of contextual factors related to cancer screening uptake that have been studied so far. Studies were identified through PubMed and Web of Science databases. An operational definition of context was proposed, considering as contextual factors: social relations directly aimed at cancer screening, health care provider and facility characteristics, geographical/accessibility measures and aggregated measures at supra-individual level. We included 70 publications on breast, cervical and/or colorectal cancer screening from 42 countries, covering a data period of 24 years. A wide diversity of factors has been investigated in the literature so far. While several of them, as well as many interactions, were robustly associated with screening uptake (family, friends or provider recommendation, provider sex and experience, area-based socio-economic status…), others showed less consistency (ethnicity, urbanicity, travel time, healthcare density …). Screening inequities were not fully explained through adjustment for individual and contextual factors. Context, in its diversity, influences individual screening uptake and lots of contextual inequities in screening are commonly shared worldwide. However, there is a lack of frameworks, standards and definitions that are needed to better understand what context is, how it could modify individual behaviour and the ways of measuring and modifying it.

Improving physician compliance with mammography screening by implementing a breast cancer screening guideline at a hospital in Bahrain

Background

From a health and safety perspective, it is critical to use adequate, evidence-based breast screening guidelines. The aim of this quality improvement project was to improve physicians’ compliance with breast cancer screening guidelines to enhance the mammography screening rate among eligible women; this was achieved through the implementation of multifaceted changes to the hospital’s processes and the improvement of physicians’ attitudes towards the guidelines.

Methods

The project used the Plan-Do-Study-Act method to implement the changes. This was a pre-post evaluation study. The data were collected from patients’ charts. The primary outcome of interest was the rate of physician compliance with mammography screening guidelines before and after the implementation of the process changes. A literature review was conducted to determine which women should be identified as eligible for mammography screening.

Intervention

The interventions targeted physician knowledge and hospital processes. Improving doctors’ expertise was achieved by implementing the US Preventive Service Task Force recommendation for mammography screening every 2 years for women aged 50–74 years. The process modifications included the establishment of a system that would be effective in identifying at-risk patients and reminding physicians at the point of care.

Results

Over the course of this study, 825 patients met the criteria for breast cancer screening. The rate of physician compliance with the breast cancer screening guideline increased from 2% to 69% after 23 weeks, and the control charts demonstrated a reliable process.

Conclusion

This project examined the relationship between different interventions (identification of the eligible patient, reminder alerts and physician knowledge) and physician compliance with mammography screening guidelines. The results suggest a positive link between the study variables and physicians’ compliance with mammography screening guidelines.

Barriers to and Facilitators of Cervical Cancer Screening among Women in Southeast Asia: A Systematic Review

In Southeast Asia, cervical cancer is the second most common cancer in women. Low coverage for cervical cancer screening (CCS) becomes a roadblock to disease detection and treatment. Existing reviews on CCS have limited insights into the barriers and facilitators for SEA. Hence, this study aims to identify key barriers and facilitators among women living in SEA. A systematic literature review was conducted on Pubmed, Embase, PsycINFO, CINAHL, and SCOPUS. Primary qualitative and quantitative studies published in English that reported barriers and facilitators to CCS were included. The Mix Methods Appraisal Tool was used for the quality assessment of the included studies. Among the 93 included studies, pap smears (73.1%) were the most common screening modality. A majority of the studies were from Malaysia (35.5%). No studies were from Timor-Leste and the Philippines. The most common barriers were embarrassment (number of articles, n = 33), time constraints (n = 27), and poor knowledge of screening (n = 27). The most common facilitators were related to age (n = 21), receiving advice from healthcare workers (n = 17), and education status (n = 11). Findings from this review may inform health policy makers in developing effective cervical cancer screening programs in SEA countries.

Model of Organizational Commitment Applied to Health Management Systems

In this paper, we try to build on the problems surrounding the management of human resources in health care organizations worldwide. After the analysis of the reviewed literature, we detected that the scientific community considers several recurring themes that need attention: stress, burnout, and turnover intention. Based on this, we developed a model of organizational commitment that aims to achieve performance and health quality, its main result the establishment of the appropriate management policies in order to avoid the abandonment of the organization through the search for commitment and job satisfaction. Amongst our main conclusions, we highlight the need to implement a human resources model for hospital administrators based on the relationships with "patients" not "clients" through the maintenance of a positive and strong atmosphere of staff participation. It is important to develop innovative practices related to clear job design that eliminate reasons for ambiguity and stress in executing the tasks of the healthcare system. Finally, we urge training programs in transformational leadership to promote the well-being and organizational commitment of employees.

Impact of postal correspondence letters on participation in cancer screening: a rapid review

The purpose of this rapid review was to identify and synthesize evidence on the impact of postal correspondence letters on participation in cancer screening and to determine whether impact varied by cancer site or inclusion of the participant's physician's name within the letter (i.e., physician-linked). PubMed and the Cochrane Database of Systematic Reviews were searched for English-language systematic reviews and randomized controlled trials (RCTs) published up until October 2019. One reviewer completed citation screening and data extraction with 30% verification by a second reviewer. Systematic reviews and RCTs were appraised using A MeaSurement Tool to Assess systematic Reviews (AMSTAR) 2 and Cochrane Risk of Bias 2.0 tools, respectively, by one reviewer with complete verification by a second reviewer. Findings from systematic reviews and RCTs were examined separately and presented narratively. Six systematic reviews and 18 RCTs of generally low quality were included. Evidence generally demonstrated a positive impact of a letter as compared to no letter or usual practice on screening participation. This finding was consistent for breast cancer and cervical screening participation but inconsistent for colorectal cancer screening participation. Studies comparing physician-linked letters to no letters or usual practice reported similar effect estimates as those examining letters in general. Limited and inconsistent evidence was identified on the impact of physician-linked letters as compared to non-physician-linked letters on screening participation. Evidence identified in this rapid review, and other contextual and implementation considerations, may be useful for jurisdictions considering how to promote cancer screening participation.

Inequalities in adherence to cervical cancer screening in Portugal

Cervical cancer is the second cancer with the highest incidence and mortality in women aged 15-44 living in Europe. Screening is an effective strategy to reduce these rates, although in Portugal, as in other European countries, adherence to screening still presents significant disparities. Thus, this study aimed to assess the prevalence and factors associated with cervical cancer screening (CCS) nonadherence in Portugal. Cross-sectional data from 5929 women aged 25-64 included in the 2014 Portuguese National Health Survey (2014 NHS) were analyzed. The prevalence of CCS nonadherence was estimated. The association between multiple factors and CCS nonadherence was analyzed, using logistic regression, adjusting for age and educational level. The weighted prevalence of nonadherence was 13.2% [95% confidence interval (CI): 12.0-14.0]. Additionally, 10.5% of women had performed the last cervical cytology 3 years ago or more. Higher odds of nonadherence to screening were found for younger women, with low levels of education and income, unemployed, single, born outside Portugal, who never had a medical appointment or had over 12 months ago, who were never pregnant and who had never had a mammography. No association was found with other variables studied, including having public/private health insurance, BMI or smoking status. This study showed that inequalities in CCS adherence in Portugal persist. These findings reinforce the need for developing strategies to reduce inequalities in CCS adherence.

Cervical cancer screening in the United States: Challenges and potential solutions for underscreened groups

Cervical cancer screening rates in the United States are generally high, yet certain groups demonstrate disparities in screening and surveillance. Individuals at greatest risk for cervical cancer are often from marginalized or underserved groups who do not participate in regular screening for a variety of reasons. Using the Population-based Research to Optimize the Screening Process (PROSPR) Trans-Organ Conceptual Model, including concepts of individual-, provider-, facility-, system-, or policy-level factors, we provide a commentary to highlight reasons for low screening participation among subgroups in the U.S. These include racial and ethnic minorities, rural residents, sexual and gender minorities, those with limited English proficiency, those with particular religious beliefs, and various health conditions. We describe barriers and offer potential solutions for each group. In addition, we discuss cross-cutting barriers to screening including difficulty interacting with the healthcare system (limited knowledge and health literacy, lack of provider recommendation/contact), financial (cost, lack of insurance), and logistical barriers (e.g., lack of usual source of care, competing demands, scheduling issues). Solutions to address these barriers are needed to improve screening rates across all underscreened groups. Changes at state and national policy levels are needed to address health insurance coverage. Mobile screening, ensuring that interpreters are available for all visits, and targeted in reach at non-gynecological visits can further overcome barriers. Employing community outreach workers can increase community demand for screening, and patient navigators can improve adherence to both screening and follow-up diagnostic evaluation. HPV self-sampling can address multiple barriers to cervical cancer screening.

Cervical cancer screening behaviors and proximity to federally qualified health centers in South Carolina

INTRODUCTION

Lack of participation in cervical cancer screening in underserved populations has been attributed to access to care, particularly among women in rural areas. Federally Qualified Health Centers (FQHCs) were created to address this need in medically underserved populations. This study observed proximity to three health centers in relation to cervical cancer screening rates in South Carolina.

METHODS

Data were obtained from FQHC patient visits (from 3 centers) between 2007-2010 and were limited to women eligible for cervical cancer screening (n = 24,393). ArcGIS was used to geocode patients addresses and FQHC locations, and distance was calculated. Modified Poisson regression was used to estimate relative risk of obtaining cervical cancer screening within one yearor ever, stratified by residential area.

RESULTS

Findings differed markedly by center and urban/rural status. At two health clinics, rural residents living the furthest away from the clinic (∼9 miles difference between quartile 4 and quartile 1) were more likely to be ever screened (RRs = 1.05 and 1.03, p-values < 0.05), while urban residents living the furthest away were less likely to be ever screened (RR = 0.85, p-value < 0.05). At the third center, only urban residents living the furthest away were more likely to be ever screened (RR = 1.02, p-value < 0.05).

CONCLUSIONS

Increased travel distance significantly increased the likelihood of cervical cancer screening at two FQHC sites while significantly decreasing the likelihood of screening at the 3rd site. These findings underscore the importance of contextual and environmental factors that impact use of cervical cancer screening services.

Adaptation and validation of the Arabic version of self-efficacy scale for mammography. A report on psychometric properties

Objectives:

To culturally adapt and validate a mammography-specific self-efficacy (MSSE) scale into Arabic for the Saudi Arabian context.

Methods:

A methodological study aimed at tool translation and adaptation conducted in primary healthcare centers in As Madinah, Saudi Arabia between March 2016 and May 2016. The MSSE scale was translated and adapted into Arabic using standard procedures. Content and face validity were investigated. Confirmatory factor analysis and reliability analysis were used to determine the scale’s psychometric properties.

Results:

The scale showed a good internal consistency (Cronbach’s alpha=0.88). The confirmatory factor analysis supported the scale’s single-factor structure and the goodness-of-fit indices confirmed the model’s good fit (comparative fit index=0.961, Tucker-Lewis index=0.943, root-mean-square error of approximation=0.076, and standardized root-mean-square residual=0.045). Women who had a mammogram in the last 2 years scored significantly higher on the scale (39±6.2) than women who had never received a mammogram (35.88±7.2; p=0.009).

Conclusion:

The study confirmed that the scale’s Arabic version has good psychometric properties, using reliability analysis, confirmatory factor analysis, and extreme groups validation. The scale is likely to be useful for evaluating interventional studies aimed at improving mammography screening participation rates.

Perceived Barriers to Mammography Adoption among Women in Iran: A Qualitative Study

Background

Breast cancer is the most commonly diagnosed tumorous cancer and the second leading cause of cancer-related deaths among women worldwide. This study aimed to qualitatively explore the barriers to mammography adoption among Iranian women.

Methods

This study is a qualitative component of a large research project on exploratory sequential mixed method design, utilizing conventional content analysis. In total, 24 participants were selected from among women who had participated in the first phase of the study. Data were collected through in-depth, semi-structured interviews.

Results

Five main themes were extracted, consisting of unawareness of mammography, fear control, priority of mammography needs, inadequate competency of mammography centers, and a sense of losing family support.

Conclusion

Different perceived barriers within various levels (individual, intrapersonal, health systems, and community) play influential roles in women’s decisions to participate in breast cancer screening program, which indicates the cultural aspect of perceived barriers in different communities and countries. The study provides the basis for intervention planning in this regard.

Chronic Comorbidities and Receipt of Breast Cancer Screening in United States and Foreign-Born Women: Data from the National Health Interview Survey

Objective: Research is limited on how immigrant status affects provider recommendations and adherence to breast cancer screening among women with chronic conditions. This study examined whether chronic comorbidities are associated with breast cancer screening recommendations and adherence, as well as differences between foreign-born and United States-born women. Materials and Methods: The study examined data from the 2013 and 2015 National Health Interview Survey on women 50-74 years of age (N = 12,425). Chi-square analysis was used to assess relationships between chronic comorbidities (hypertension, diabetes, and obesity) and mammography screening recommendation and adherence (screened in the last 3 years). Multivariable binary logistic regression analysis examined the relationship between foreign-born status and mammography screening, adjusting for provider screening recommendation and chronic comorbidities. Results: Obesity and hypertension were positively associated with mammography screening recommendation and adherence (p < 0.05). United States-born women, compared with foreign-born women, had higher rates of obesity (28% vs. 24%, p < 0.001) and hypertension (44% vs. 41%, p < 0.001). Compared with normal-weight women, underweight women (odds ratio [OR]: 0.57, confidence interval [CI]: 0.39-0.82) were significantly less likely to report receiving mammograms. In stratified analyses, foreign-born underweight women (OR: 0.25, CI: 0.09-0.68) remained less likely to report receiving mammograms after controlling for years lived in the United States and citizenship status. Conclusion: Public health intervention efforts must encourage mammography screening for both United States-born and foreign-born women, especially those diagnosed with chronic conditions.

Multilevel Predictors of Continued Adherence to Breast Cancer Screening Among Women Ages 50-74 Years in a Screening Population

Background: U.S. women of ages 50-74 years are recommended to receive screening mammography at least biennially. Our objective was to evaluate multilevel predictors of nonadherence among screened women, as these are not well known. Materials and Methods: A cohort study was conducted among women of ages 50-74 years with a screening mammogram in 2011 with a negative finding (Breast Imaging-Reporting and Data System 1 or 2) within Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium research centers. We evaluated the association between woman-level factors, radiology facility, and PROSPR research center, and nonadherence to breast cancer screening guidelines, defined as not receiving breast imaging within 27 months of an index screening mammogram. Multilevel mixed-effects logistic regression was used to calculate odds ratios and 95% confidence intervals. Results: Nonadherence to guideline-recommended screening interval was 15.5% among 51,241 women with a screening mammogram. Non-Hispanic Asian/Pacific Islander women, women of other races, heavier women, and women of ages 50-59 years had a greater odds of nonadherence. There was no association with ZIP code median income. Nonadherence varied by research center and radiology facility (variance = 0.10, standard error = 0.03). Adjusted radiology facility nonadherence rates ranged from 10.0% to 26.5%. One research center evaluated radiology facility communication practices for screening reminders and scheduling, but these were not associated with nonadherence. Conclusions: Breast cancer screening interval nonadherence rates in screened women varied across radiology facilities even after adjustment for woman-level characteristics and research center. Future studies should investigate other characteristics of facilities, practices, and health systems to determine factors integral to increasing continued adherence to breast cancer screening.

Predicting cervical cancer screening among sexual minority women using Classification and Regression Tree analysis

Cervical cancer screening is a critical preventive healthcare service for all women. Sexual minority women (SMW) in the United States experience multiple health disparities including decreased access to and use of cervical cancer screening. The mechanisms driving these disparities are not clear and SMW with multiple marginalized identities may be more likely to miss recommended cervical cancer screening. This study aimed to identify subgroups of SMW that are more and less likely to be screened for cervical cancer according to American Cancer Society guidelines. We used cross-sectional data from the latest (2010-2012) wave of the Chicago Health and Life Experiences of Women (CHLEW) Study (N = 691). Informed by intersectionality theory, we performed classification and regression tree (CART) modeling to construct a data-driven, predictive model of subgroups of SMW who were more and less likely to receive guideline-recommended screening. Notably, the CART model did not include commonly tested variables such as race/ethnicity or level of income or education. The model did identify subgroups with low likelihood of receiving screening and several novel variables that may be important in understanding SMW's use of cervical cancer screening; lifetime number of sexual partners, age at drinking onset, childhood physical abuse, and internalized homonegativity. Our results point to the importance of early life experiences and identity development processes in shaping patterns of preventive healthcare use among adult SMW. Our analysis also demonstrated the potential value of CART modeling techniques for evaluating how multiple variables interact in complex ways to predict cervical cancer screening.

The Association Between Continuity of Primary Care and Preventive Cancer Screening in Women With Intellectual Disability

Women with intellectual disability have low screening rates for breast and cervical cancer. This population-based cohort study examined the association between the level of primary care continuity and breast and cervical cancer screening rates in women with intellectual disability. Data were obtained from the Institute for Clinical Evaluative Sciences and the Ontario Ministry of Community and Social Services. Neither high (adjusted OR [aOR] = 1.06; 95% CI: 0.88-1.29) nor moderate (aOR = 1.11; 95% CI: 0.91-1.36) continuity of care were associated with mammography screening. Women were less likely to receive a Pap test with high (aOR = 0.70; 95% CI: 0.64-0.77) and moderate (aOR = 0.81, 95% CI 0.74-0.89) versus low continuity of care. Improving continuity of care may not be sufficient for increasing preventive screening rates.

Preference for Human Papillomavirus Self-Collection and Papanicolaou: Survey of Underscreened Women in North Carolina

OBJECTIVES

Self-collection of samples for human papillomavirus (HPV) testing (self-collection) has the potential to increase cervical cancer screening among underscreened women. We assessed attitudes toward at-home HPV self-collection compared with clinic-based Pap testing in this higher-risk population.

MATERIALS AND METHODS

Participants were low-income women in North Carolina overdue for cervical cancer screening. Women self-collected samples at home, returned samples by mail for HPV testing, and completed phone questionnaires about at-home HPV self-collection. Participants were referred to clinic-based Pap testing and invited to complete a second questionnaire about Pap testing. A cross-sectional questionnaire compared attitudes, experiences, and preferences for self-collection versus Pap testing and assessed predictors of preference for HPV self-collection.

RESULTS

Half (51%) of 221 women reported a preference for HPV self-collection, 19% preferred Pap testing, and 27% reported no preference. More women reported difficulty finding time to do the Pap test (31%) than the self-test (13%, p = .003) and being afraid of the self-test results (50%) than the Pap test results (36%, p = .02). There were relatively fewer reports of physical discomfort and pain from self-collection than Pap testing (discomfort: 18% self; 48% Pap; pain: 8% self; 30% Pap, p = .001). No differences were found in positive versus negative thoughts about the tests, trust in the tests' safety and accuracy, or willingness to do tests again.

CONCLUSIONS

Overall positive attitudes toward HPV self-collection compared with Pap testing among underscreened women suggest that self-collection is a promising option to increase cervical cancer screening in this high-risk population.

Health Care-Related Correlates of Cervical Cancer Screening among Sexual Minority Women: An Integrative Review

INTRODUCTION

Sexual minority women (SMW; lesbian, bisexual, nonheterosexual women) may have lower rates of cervical cancer screening than heterosexual women. Health care-related factors may explain some of the variation in cervical cancer screening rates among SMW. We aimed to synthesize published evidence of health care-related correlates of cervical cancer screening among SMW.

METHODS

We searched PubMed, CINAHL, and PsycINFO databases for English-language studies published between January 2000 and March 2017 that 1) assessed sexual identity or the sexual partners of female participants, 2) included cervical cancer screening as a main outcome of interest, and 3) measured at least one health care-related variable in addition to cervical cancer screening. We excluded articles that 1) reported on non-US samples or 2) did not report original research. We reviewed the sample, methods, and findings of 17 studies. We then summarized current knowledge about health care-related factors across 3 categories and generated recommendations for clinical practice and future research.

RESULTS

Several health care-related factors such as previous contraception use, having a primary care provider, knowledge of screening recommendations, and disclosing sexual orientation to providers were consistently positively associated with cervical cancer screening. Three groups of factors-previous health care use, health care provider-related factors, and belief-related factors-account for a substantial part of the variation in cervical cancer screening among SMW.

DISCUSSION

Several gaps in knowledge remain that could be addressed by recruiting more diverse samples of SMW with improved generalizability. Clinicians and clinical institutions can address factors associated with low rates of screening among SMW by preventing sexual orientation-based discrimination, inviting sexual orientation disclosure, and offering cervical cancer screening to SMW at a variety of health care encounters. Future research should examine how the location of care and health care provider type affect SMW's cervical cancer screening behaviors and should test the effectiveness of health care interventions designed to address sexual orientation-related disparities.

Association of Pregnancy History and Cervical Cancer Screening in a Community Sample of Sexual Minority Women

BACKGROUND

Sexual minority women (SMW) face barriers to healthcare that may result in lower utilization of cervical cancer screening. Previous experiences with the healthcare system-specifically reproductive health-related encounters-have the potential to affect future use of screening services. This study aimed to examine the association between pregnancy history and cervical cancer screening in a diverse sample of SMW. Anderson's Behavioral Model of Health Services Use guided the selection of variables included in the study.

METHODS

We performed a secondary analysis of cross-sectional data from the third wave of the Chicago Health and Life Experiences of Women (CHLEW) Study, a longitudinal study of SMW in the Midwestern United States. We performed multivariable logistic regression to address the study aims, restricting the sample to women ages 21-45 (n = 430).

RESULTS

Reporting a previous pregnancy was consistently positively associated with past-year Pap testing. In the multivariable model, bisexual identity and disclosing one's sexual orientation to healthcare providers were also positively associated with past-year Pap test.

CONCLUSIONS

This analysis provides preliminary evidence that SMW who have been pregnant are more likely to receive Pap testing and that multiple sociodemographic factors are likely to impact screening in this population. Clinicians should screen all patients with a cervix for cervical cancer and should encourage screening for all SMW. Future studies should prioritize longitudinal analyses to examine the temporality of reproductive history and healthcare seeking, focus on where SMW seek care, and understand how intersecting components of identity may shape the healthcare utilization of this population.

Combined diagnosis of breast cancer in the early stage by MRI and detection of gene expression

Breast cancer is one of the most common cancer types in humans. Magnetic resonance imaging (MRI) is an efficient method for the detection of human breast cancer. However, the efficacy of MRI in detecting breast cancer in the early stage requires to be improved. The present study investigated the diagnostic efficacy of a combination of MRI and detection of gene expression in patients with breast cancer in the early stage. The gene expression levels of Ki-67, BCL11A, FOXC1, HOXD13, PCDHGB7 and her-2 were used as an auxiliary diagnostic index for patients with breast cancer in the early stage. Higher expression levels of TPA and C2erbB22 were observed in tumor tissue obtained from diagnostic biopsy and determined by immunohistochemistry, which indicated a higher risk of breast cancer in a total of 84 participants. Diagnostic data revealed that combination MRI and detection of gene expression had a significantly higher diagnostic rate (66/84) in diagnosing breast cancer in an early stage compared with either MRI (78/360) or detection of gene expression (72/84; P<0.01). It was indicated that the combination of MRI and detection of gene expression had a higher diagnostic rate (94.5%) than either MRI (81.4%) or detection of gene expression (75.5%). Histological analysis confirmed the diagnosis determined by MRI and detection of gene expression. These results suggest that the combination of MRI and detection of gene expression may be a potential diagnostic method for assessing patients with early-stage breast cancer.

Breast cancer screening initiation after turning 40 years of age within the PROSPR consortium

PURPOSE

Although United States clinical guidelines differ, the earliest recommended age for average risk breast cancer screening is 40 years. Little is known about factors influencing screening initiation.

METHODS

We conducted a cohort study within the National Cancer Institute-funded Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium. We identified 3413 women on their 40th birthday in primary care networks at Geisel School of Medicine at Dartmouth (DH) and Brigham and Women's Hospital (BWH) during 2011-2013 with no prior breast imaging or breast cancer. Cumulative incidence curves and Cox modeling were used to determine time from the 40th birthday to first breast cancer screening, cohort exit, or 42nd birthday. We calculated hazards ratios and 95 % confidence intervals from multivariable Cox proportional hazards models.

RESULTS

Breast cancer screening cumulative incidence by the 42nd birthday was 62.9 % (BWH) and 39.8 % (DH). Factors associated with screening initiation were: a primary care visit within a year (HR 4.99, 95 % CI 4.23-5.89), an increasing number of primary care visits within a year (p for trend <0.0001), ZIP code of residence annual median household income ≤$52,000 (HR 0.79, 95 % CI 0.68-0.92), and health insurance type (Medicaid HR 0.72, 95 % CI 0.58-0.88; Medicare HR 0.55, 95 % CI 0.39-0.77; uninsured HR 0.37, 95 % CI 0.25-0.57).

CONCLUSIONS

Breast cancer screening uptake after the 40th birthday varies by health system, primary care visits, median household income, and health insurance type, suggesting the need for further exploration. Future research should evaluate screening performance metrics after initiation and consider cumulative benefits and risks associated with breast cancer screening over time.
