Factors Associated with Adherence to Mammography Screening Among Insured Women Differ by Income Levels

Research Guided by the Theory of Care-Seeking Behavior: A Scoping Review

BACKGROUND

A particular Theory of Care-Seeking Behavior was developed to explain care-seeking behavior with psychosocial concepts, external conditions, and clinical and demographic factors. Having a careful review of studies based on this theory could guide future research on care-seeking behaviors.

OBJECTIVES

With a scoping review: describe characteristics of studies guided by a Theory of Care-Seeking Behavior, summarize support for the relationships of proposed, explanatory variables with care-seeking behaviors, and examine support for propositions in the theory.

METHOD

Searching 5 electronic databases, we sought studies that were: full-text, peer-reviewed, in English, data-based, guided by the theory, and published from January 1, 1992, to January 1, 2022.

RESULTS

Across 18 identified articles, the behaviors studied included: symptomatic screening (n = 8), asymptomatic screening (n = 7), and care-seeking behaviors for either screening or symptoms (n = 3). A total of 3328 adults participated in the studies. In 16 studies, all participants were female. In 60% to 83% of studies, researchers had reported findings that supported the relationships of explanatory concepts with care-seeking behavior. Among the 7 studies that tested the 2 propositions of theory, all 7 tests failed to support the proposition that clinical and demographic factors influence care-seeking behavior indirectly through psychosocial variables. Six tests supported the proposition that psychosocial variables influence behavior conditionally, on external conditions.

CONCLUSIONS

Relationships of these explanatory variables with care-seeking behaviors were supported, as was 1 of 2 propositions. The Theory of Care-Seeking Behavior can be applied to new clinical situations to continue to build knowledge of the theory and understanding of care-seeking behaviors.

Identifying Frequently Endorsed Benefits and Barriers to Breast Cancer Screening for African-Born Women in the NYC Metropolitan Area: a Pilot Study

Most cancer screening data report on Black participants without distinguishing nativity, limiting our understanding of the needs of distinct groups within the African diaspora. The purpose of this pilot study was to assess demographic characteristics and perceptions of the benefits of and barriers to mammography among African immigrant women in New York City (NYC). Forty-two women who were 40 years or older, born in Africa, and English and/or French-speaking were recruited from African immigrant communities in NYC to complete a survey. Eighty percent of our sample aged 50 to 73 was adherent to the 2016 USPSTF mammography screening guideline. The most frequently endorsed benefits were that mammography will help find breast cancer early, could help find a breast lump before it is big enough to feel, and that if found early, breast cancer could be successfully treated. The most endorsed barriers were that having a mammogram is painful and that lack of insurance or being treated rudely at the mammogram center would keep participants from having a mammogram. Chi-square analyses assessed relationships between demographic characteristics and perceptions about mammography and revealed that endorsement of barriers to screening (e.g., health issues, transportation problems, pain, and time associated with mammography) varied by educational attainment. Findings suggest that future interventions should be multi-level and (1) support patients in accessing screening via resource sharing, (2) address other commonly cited barriers such as fear of pain during the procedure, and (3) support anti-racist healthcare environments especially in terms of treatment by providers.

Breast Cancer Risk Assessment and Screening Practices Reported Via an Online Survey

BACKGROUND

Breast cancer screening guidelines differ between organizations, and significant variations in practice patterns exist. Previous evidence suggests that provider-level factors are the greatest contributors to risk assessment and screening practice variability. This study aimed to characterize provider factors associated with breast cancer risk assessment and screening practice patterns, and to assess perceived barriers to providing risk assessment.

METHODS

An online survey was distributed to providers at a single academic institution and to providers publicly via social media (January to August 2022). Respondents in the United States who care for adult women at risk for the development of breast cancer were included.

RESULTS

Most of the respondents in the 143 completed surveys were white/Caucasian (79%) females (90%) age 50 years or younger (79%), and whereas 97% discuss breast cancer screening with their patients, only 90% order screening mammograms. Risk factor assessment was common (93%), typically performed at the first visit (51%). Additional training in genetics or risk assessment was uncommon (17%), although the majority were interested but did not have the time or resources (55%). Although most (64%) did not perceive barriers to providing risk assessment or appropriate screening, the most common barriers were time (77%) and education (55%). Barriers were more common among family practice or obstetrics and gynecology (OB/GYN) providers and those who worked in an academic setting (all p < 0.05).

CONCLUSIONS

Breast cancer risk assessment and screening practices are highly variable. Although time is the major barrier to providing risk assessment, providers also need education. Primary care organizations could partner with breast cancer-focused societies for additional resources.

Implementation of an Evidence-Based Intervention with Safety Net Clinics to Improve Mammography Appointment Adherence Among Underserved Women

The Peace of Mind Program is an evidence-based intervention to improve mammography appointment adherence in underserved women. The aim of this study was to assess effectiveness of the intervention and implementation of the intervention in safety net clinics. The intervention was implemented through a non-randomized stepped wedge cluster hybrid study design with 19 Federally Qualified Health Centers and charity care clinics within the Greater Houston area. A multivariable generalized estimating equation logistic regression was conducted to examine mammography appointment adherence. A survey assessing Consolidated Framework for Implementation Research constructs was also conducted with clinic staff prior to adoption and eight weeks post implementation. One-sided t-tests were conducted to analyze mean score changes between the surveys. A total of 4402 women (baseline period = 2078; intervention period = 2324) were included in the final regression analysis. Women in the intervention period were more likely to attend or reschedule their mammography appointment (OR = 1.30; p < 0.01) than those in the baseline period receiving usual care. Women who completed the intervention were more likely to attend or reschedule their mammography appointment than those who did not complete the intervention (OR = 1.62; p < 0.01). The mammography appointment no-show rates for those in the baseline period, in the intervention period, and who completed the intervention were, respectively, 22%, 19%, and 15%. A total of 15 clinics prior to adoption and eight clinics completed the survey at 8 weeks post implementation A statistically significant mean score decrease was observed in Inner Setting and in two Inner Setting CFIR constructs, Culture-Effort, and Implementation Climate. While the intervention improved mammography appointment adherence, there are opportunities to further integrate Consolidated Framework for Implementation Research constructs.

Participation and adherence to mammography screening in the Capital Region of Denmark: The importance of age over time

Mammography screening's effectiveness depends on high participation levels. Understanding adherence patterns over time is important for more accurately predicting future effectiveness. This study analyzed longitudinal adherence to the biennial invitations in the Capital Region of Denmark from 2008-2017. We analyzed participation rates for five-year age groups along with their percent changes in each invitation round using linear regressions. Participation in the mammography screening program increased from 73.1% to 83.1% from 2008-2017. The participation rate among all age groups increased from the first to the fifth round, with the oldest age group having the largest increase (average percent change = 3.66; p-value = 0.03).

Use of breast surveillance between women with pathogenic variants and variants of uncertain significance in breast cancer susceptibility genes

BACKGROUND

Use of surveillance mammography and magnetic resonance imaging (MRI) has been understudied among women with variant of uncertain significance (VUS) compared to pathogenic and likely pathogenic variants (P/LP).

METHODS

Using data from two cancer settings, we calculated use of risk-reducing mastectomy (RRM) and surveillance during each 13-month span after genetic testing up to 6 years afterwards for a cohort of genetically elevated risk women.

RESULTS

Of 889 women, VUS carriers were less likely to undergo RRM compared to those with P/LP (hazard ratio [HR], 0.17; p = <.001) and high-risk women were more likely to undergo RRM than average-risk women (HR, 3.91; p = .005). Longitudinally, surveillance use among unaffected women decreased from 49.8% in the first year to 31.2% in the sixth year after genetic testing. In comparison, a greater proportion of women with a personal history of breast cancer underwent surveillance, which increased from 59.3% in the first year to 63.6% in the sixth year after genetic testing. Mammography rates did not differ between women with P/LP and VUS within the first 13 months after genetic testing and up to 4 years afterward. Over the first 4 years after genetic testing, women with VUS were less likely to undergo annual MRIs compared to P/LP.

CONCLUSION

The authors found that VUS, whether in high or moderate penetrance breast cancer susceptibility genes, was associated with lower use of annual breast MRI compared to P/LP variants and equivalent use of annual mammography. These results add important evidence regarding VUS-related breast surveillance.

The Effect of Two Interventions to Increase Breast Cancer Screening in Rural Women

Guideline-based mammography screening is essential to lowering breast cancer mortality, yet women residing in rural areas have lower rates of up to date (UTD) breast cancer screening compared to women in urban areas. We tested the comparative effectiveness of a tailored DVD, and the DVD plus patient navigation (PN) intervention vs. Usual Care (UC) for increasing the percentage of rural women (aged 50 to 74) UTD for breast cancer screening, as part of a larger study. Four hundred and two women who were not UTD for breast cancer screening, eligible, and between the ages of 50 to 74 were recruited from rural counties in Indiana and Ohio. Consented women were randomly assigned to one of three groups after baseline assessment of sociodemographic variables, health status, beliefs related to cancer screening tests, and history of receipt of guideline-based screening. The mean age of participants was 58.2 years with 97% reporting White race. After adjusting for covariates, 54% of women in the combined intervention (DVD + PN) had a mammogram within the 12-month window, over 5 times the rate of becoming UTD compared to UC (OR = 5.11; 95% CI = 2.57, 10.860; p < 0.001). Interactions of the intervention with other variables were not significant. Significant predictors of being UTD included: being in contemplation stage (intending to have a mammogram in the next 6 months), being UTD with other cancer screenings, having more disposable income and receiving a reminder for breast screening. Women who lived in areas with greater Area Deprivation Index scores (a measure of poverty) were less likely to become UTD with breast cancer screening. For rural women who were not UTD with mammography screening, the addition of PN to a tailored DVD significantly improved the uptake of mammography. Attention should be paid to certain groups of women most at risk for not receiving UTD breast screening to improve breast cancer outcomes in rural women.

Impact of Health Care-Associated Cost Concerns on Mammography Utilization: Cross-Sectional Survey Results From the National Health Interview Survey

PURPOSE

Health care-related cost concerns and financial toxicity are increasingly recognized barriers along the breast cancer care continuum. The purpose of this study was to evaluate the association between patient-reported cost concerns and screening mammography utilization.

METHODS

Survey participants aged 40 to 74 years from the 2018 National Health Interview Survey without personal history of breast cancer were included (response rate: 64%). Respondents were queried if they had experienced specific access-related health care barriers. Multiple variable logistic regression analyses were performed to evaluate the association between barriers to care and patient-reported screening mammography utilization.

RESULTS

Of survey respondents, 7,511 women were included. Of this group, 68.9% reported receiving a screening mammogram within the last 2 years and 52.2% reported receiving a screening mammogram within the last year. Of all survey respondents, 48.4% reported worry paying medical bills. Patients who reported worry about paying medical bills (odds ratio [OR] 0.86; 95% confidence interval [CI]: 0.76-0.97; P = .01), challenges affording dental care (OR 0.65; 95% CI: 0.54-0.77; P < .01), and challenges affording eyeglasses (OR 0.67; 95% CI: 0.54-0.84; P < .01) were less likely to report screening mammography use than their respective counterparts. Patients who skipped medication doses (OR 0.69; 95% CI: 0.52-0.91; P < .01), took less medication, (OR 0.63; 95% CI: 0.48-0.82; P < .01), and delayed filling prescriptions (OR 0.71; 95% CI: 0.56-0.90; P < .01) to save money were also less likely to report receiving mammography screening.

CONCLUSION

Patient-reported cost-related barriers are associated with decreased utilization of routine mammography.

Melanoma Skin Self-Examination Education During Mammography: Health Burden of Women Impairs Implementation

Identification of barriers to seeking health care for a concerning mole found during skin self-examination (SSE) by women educated during screening mammography. In this sequential mixed methods research, interviews with women who found a concerning mole and did not have health-care follow-up were analyzed and a survey was created. One year after SSE education, barriers to having health care for a self-identified concerning mole were assessed. The electronic medical records for all participants, who received education, were reviewed to ascertain who received health care related to a concerning mole or a screening mammogram. Among the 280 women who performed SSE, 85 found a concerning mole. Nine months later 51 women did not receive health care for the mole. Barriers were the burden of other medical concerns, fear of what the doctor will find, feeling like nothing is wrong, and being too busy. A positive screening mammogram (Fisher's two-sided exact test, p < 0.001) and a history of indoor tanning (Fisher's two-sided exact test, p = 0.011) were significantly associated with lack of follow-up for a concerning mole. Targeted melanoma self-identification with SSE relies upon participants initiating performance and seeking medical care for a concerning mole. The burden of a positive screening mammogram reported to women at about the same time as they identified the concerning mole was associated with failing to seek care for their concerning mole. Reminders to check moles for change 4 months after identifying a concerning mole may benefit women. Clinicaltrials.gov NCT03512457.

Mediation Effect of Health Beliefs in the Relationship Between Health Knowledge and Uptake of Mammography in a National Breast Cancer Screening Program in Taiwan

Despite evidence that breast cancer screening effectively diagnoses and treats cancer through early detection, mammography use remains low in Taiwan. We applied the health belief model (HBM) and the knowledge-attitude-behavior (KAB) model as theoretical frameworks to examine factors associated with mammography uptake among women aged 45-69 years in Taiwan. A cross-sectional survey January-July 2018 was conducted of women aged 45-69 years in five southern Taiwan health institutions. Survey questionnaires included demographics, HBM constructs, and health knowledge regarding breast cancer and screening. Multivariable logistic regression models explored the mediation effects of HBM constructs between health knowledge and mammography use. The final analytical sample included 621 women; 67 did not receive mammography and 554 received mammography. When the regression model was adjusted only for demographic factors, women with adequate health knowledge were more likely to undergo mammography (AOR = 2.321, 95%CI = 1.141-3.809); in regression models including health knowledge and HBM constructs, the likelihood effect of health knowledge declined and became insignificant (AOR = 1.711, 95%CI = 0.985-2.972), indicating potential mediation effects between health knowledge and up-to-date mammography use. Overall, based on the HBM and the KAB theoretical framework, our data support that health belief played a substantial mediating role in the association between health knowledge and mammography uptake, in particular perceived barriers and cues to action in the HBM, which were modifying factors of health beliefs. Therefore, to improve mammography uptake, it may be helpful to design educational model-based interventions through tackling those modifiable perceived barriers and enhancing the intensity of external cues to action.

Relationship of attitudes toward uncertainty and preventive health behaviors with breast cancer screening participation

Backgroundcxs

Early detection of breast cancer is effective for prolonging survival, but the participation rate in breast cancer screening among target Japanese women remains low. This study examined the relationships between tendencies in decision-making under conditions of uncertainty, health behaviors, demographics, and breast cancer screening participation in Japanese women.

Methods

Secondary analysis was performed using data from the 2017 Keio Household Panel Survey (KHPS). The study population consisted of 2945 households. Data were obtained from the KHPS for women aged 40 years or older. Breast cancer screening participation in the past year, risk aversion, time preference, health behaviors (e.g., smoking, alcohol consumption, and medical treatment received in the past year), and demographic variables were analyzed.

Results

Data from 708 women were analyzed. Among the respondents, 28.8% had attended breast cancer screening in the past year. Factors found to significantly contribute to breast cancer screening participation included higher risk aversion (odds ratio [OR], 2.34; 95% confidence interval [CI] = 1.03–5.32; p = 0.043), medical treatment received in the past year (OR, 1.56; 95% CI = 1.06–2.30; p = 0.026), higher self-rated health (OR, 1.47; 95% CI = 1.18–1.83; p = 0.001), living above the poverty line (OR, 2.31; 95% CI = 1.13–4.72; p = 0.022), and having children (OR, 1.57; 95% CI = 1.02–2.42; p = 0.042). Factors significantly associated with non-participation in breast cancer screening were smoking (OR, 0.20; 95% CI = 0.10–0.42; p < 0.000), alcohol consumption (OR, 0.56; 95% CI = 0.37–0.86; p = 0.007), being self-employed (OR, 0.22; 95% CI = 0.10–0.46; p < 0.000), and being unemployed (OR, 0.48; 95% CI = 0.26–0.90; p = 0.022). No significant relationship was observed between time preference and screening participation.

Conclusions

The results indicate that women who recognize the actual risk of developing breast cancer or have high awareness of breast cancer prevention tend to participate in breast cancer screening. Barriers to screening participation are not working for an organization that encourages screening and low income.

Health Iniquity, Unhealthy Behavior, and Coverage of Mammography in Brazil

OBJECTIVE

To investigate the prevalence of mammography screening and the association among socio-demographic, behavior factors and non-adherence to mammography screening among women between 50 and 69 years old, using data from Vigitel 2016.

METHOD

Cross-sectional, population-based study with data from Vigitel including 12,740 women in the 50-69 age group. The variables were analyzed using logistic regression.

RESULTS

Among the women studied, 21.8% had not had a mammography in the past 2 years. The characteristics associated with non-adherence to the test were having less than 12 years of education (p<0.001), having no partner (p=0.001), being underweight (p=0.002), having a negative self-perceived health status (p<0.001) and having at least one negative health behavior (p<0.001).

CONCLUSION

There is a subgroup of women with markers of social vulnerability, which reflect the inequality in mammography screening.

Identifying an association between socio-demographic factors and breast cancer screening adherence in a federally qualified health centre sample in the United States. A retrospective, cross-sectional study

Federally Qualified Health Centres (FQHC) are community-based centres in the United States, intended to fill a gap in care for underserved populations, including Medicaid patients and the homeless. Because of the Affordable Care Act, passed into law in 2010, there was a 29% increase in Medicaid enrolees nationally. One service offered at FQHCs is breast cancer screening. Breast cancer screening has been shown to have the lowest adherence levels among low-income women and homeless women. As they serve patients with socio-economic barriers, FQHCs are a vital resource in ensuring access to such screening. This study aimed to identity an association between socio-demographic factors and breast cancer screening adherence in FQHC patients that included the homeless. This exploratory, cross-sectional, retrospective study looked at encounter level data from a FQHC in a major metropolitan (Chicago, IL) area from January 1st, 2017 through December 31st, 2018. Data were collected in January of 2019. This was a convenience sample. Association was tested through bivariate chi-square tests and multivariate logistic regression analysis, investigating the association between socio-demographic characteristics and compliance (Yes/No) for breast cancer screening. Results showed age (55-59; 65-69) and homeless status (doubling-up, transitional) showed a positive association with breast cancer screening, while insurance status (self-pay) had a negative association. Age, homeless status and insurance type were significantly associated with adherence. Demographic characteristics in the homeless population can be used to identify nonadherence.

Social Determinants of Breast Cancer Screening among Married Women: A Cross-Sectional Study

BACKGROUND

Regular cancer screening is the best way for early detection of breast cancer, but studies showed the low participation rates of screening in Iran. We aimed to determine breast cancer screening among married women and related factors in North of Iran.

STUDY DESIGN

A cross-sectional study.

METHODS

This cross-sectional study was carried out from Jan to Mar 2017 among 1472 married women in an urban population in Rasht City, North of Iran. Data were collected using a questionnaire included socio-demographic information and breast cancer screening behaviors. Descriptive statistics, chi-square and logistic regression were used for data analyzing with SPSS.

RESULTS

The mean age of women was 35.1 ±6.5 years. Majority of women never performed clinical breast examination (70.7%) and regular monthly breast self-examination (52.2%). Only women over 40 yr performed mammography. Mammography performance was associated with health insurance (OR=4.99; 95% CI: 1.10, 22.53) and family history (OR=1.60; 95% CI: 1.19, 2.19), clinical breast examination was associated with age of women (OR=2.87; 95% CI: 1.90, 4.32) and breast self-examination was associated with age and occupation of women [OR=1.67; 95 % CI: 1.16, 2.39, OR=1.65; 95% CI: 1.19, 2.29) respectively].

CONCLUSION

The rate of breast cancer screening was low among married women. Therefore considering the structural and cultural barriers, effective health education is essential to reduce inequality and increase the efficiency of screening programs.
