Breast Cancer Screening Utilization Research Articles

Effectiveness of communication in promoting utilisation of breast cancer screening services among women working in Anganwadi centres.

Breast cancer is the most common cancer among females, worldwide. Cancer screening in developing countries is mainly opportunistic type, characterized by low coverage and over-screening of women with increased access to health care services. This study was thus designed to understand the various factors preventing the participation and utilization of breast cancer screening, thereby study the different approaches for encouraging their participation and also the effectiveness of different ways of communication to Anganwadi Workers (AWW) and Anganwadi Helpers (AWH) in increasing breast cancer screening uptake at cancer screening camps. It was a mixed-method study design among Anganwadi workers and helpers. The study included 376 Anganwadi workers working in Kolar and Bangarpete Talukas. The trained Anganwadi supervisor followed by the respective PHC medical officer (in the intervention group) invited the AWW and AWH for breast cancer screening and only through Anganwadi supervisor (in control group). Those women (AWW and AWH) who did not attend the breast cancer screening camp were listed and contacted through mobile phone to find out the reasons for the same. The data were analysed using SPSS statistics version 22; Chi-square and logistic regression were used to test significance. There were 186 subjects in the intervention and 190 subjects in the control group. The mean (SD) age in intervention and control groups was 43.7 (8.5) and 44.2 (8.7) years, respectively. Amongst the 376 women (AWW and AWH) invited for the breast cancer screening service from both the groups, a total of 238 (63.2%) of them attended screening camp. The screening uptake was more in the intervention group (73.4%) compared with the control group (53.6%). This difference across the two groups (20%) was found to be statistically significant. The sub-category 'anxiety' (31.9%) was reported to be the highest barrier and least was in the sub-category 'no replacement' (4.3%). The sub-categories are also supported by verbatim quotes. The uptake of screening was more in the intervention group (73.4%) compared with the control group (53.6%). This difference of 20% was found to be statistically significant on univariate analysis (P < 0.001). After adjusting for confounders, it was found that both the approaches were equally effective.

Breast cancer screening among Medicare Advantage enrollees with dementia

BackgroundThe decision to screen for breast cancer among older adults with dementia is complex and must often be individualized, as these individuals have an elevated risk of harm from over-screening. Medicare beneficiaries with dementia are increasingly enrolling in Medicare Advantage plans, which typically promote receipt of preventive cancer screening among their enrollees. This study examined the utilization of breast cancer screening among Medicare enrollees with dementia, in Medicare Advantage and in fee-for-service Medicare.MethodsWe conducted a pooled cross-sectional study of women with Alzheimer’s disease and related dementias or cognitive impairment who were eligible for mammogram screening. We used Medicare Current Beneficiary Survey data to identify utilization of biennial mammogram screening between 2012 and 2019. Poisson regression models were used to estimate prevalence ratios of mammogram utilization and to calculate adjusted mammogram rates for Medicare Advantage and fee-for-service Medicare enrollees with dementia, and further stratified by rurality and by dual eligibility for Medicare and Medicaid.ResultsMammogram utilization was 16% higher (Prevalence Ratio [PR] 1.16; 95% CI: 1.05, 1.29) among Medicare Advantage enrollees with dementia, compared to their counterparts in fee-for-service Medicare. Rural enrollees experienced no significant difference (PR 0.99; 95% CI: 0.72, 1.37) in mammogram use between Medicare Advantage and fee-for-service Medicare enrollees. Among urban enrollees, Medicare Advantage enrollment was associated with a 21% higher mammogram rate (PR 1.21; 95% CI: 1.09, 1.35). Dual-eligible Medicare Advantage enrollees had a 34% higher mammogram rate (PR 1.34; 95% CI: 1.10, 1.63) than dual-eligible fee-for-service Medicare enrollees. Among non-dual-eligible enrollees, adjusted mammogram rates were not significantly different (PR 1.11; 95% CI: 0.99, 1.24) between Medicare Advantage and fee-for-service Medicare enrollees.ConclusionsMedicare beneficiaries age 65–74 with Alzheimer’s disease and related dementias or cognitive impairment had a higher mammogram use rate when they were enrolled in Medicare Advantage plans compared to fee-for-service Medicare, especially when they were dual-eligible or lived in urban areas. However, some Medicare Advantage enrollees with Alzheimer’s disease and related dementias or cognitive impairment may have experienced over-screening for breast cancer.

Unmet Social Needs and Breast Cancer Screening Utilization and Stage at Presentation

Unmet social needs in local populations may hinder the development of targeted cancer control interventions aimed at improving screening utilization and early-stage breast cancer diagnosis to ultimately improve breast cancer survival disparities. To evaluate if (1) city-funded screening mammography is associated with utilization of screening mammography, (2) unmet social needs are associated with utilization of screening mammography, and (3) unmet social needs are associated with later-stage disease at diagnosis. This cohort study included patients with stages I-IV invasive ductal or lobular carcinoma treated at an academic medical center (including both an underserved safety-net hospital [SNH] and a National Cancer Institute-designated academic cancer center [ACC]) from 2020 to 2023. Eligible patients were aged 18 years or older and able to consent. Data were analyzed between July 2023 and September 2023. The Health Leads Social Needs Screening Toolkit, a screening tool that gathers information on the most common social need domains affecting patient health. Univariable and multivariable logistic regression was utilized to evaluate the following primary outcomes: (1) routine screening mammography and (2) American Joint Committee on Cancer 8th edition clinical stage at presentation. Of the 322 women who completed the Health Leads Social Needs Screening Toolkit, 201 (62%) self-identified as Hispanic, 63 (19%) as non-Hispanic Black, and 63 (19%) as non-Hispanic White. Two hundred fifty-five (76%) patients with access to city-funded screening mammography completed a screening mammogram. Patients who presented to the SNH were more likely to present with late-stage disease compared with early-stage disease (15 of 48 [31%] vs 50 of 274 [18%]; P = .04). On multivariable logistic regression, not completing a screening mammography was associated with having an increasing number of unmet social needs (OR, 0.74; 95% CI, 0.55-0.99; P = .047) and an increasing age at diagnosis (OR, 0.92; 95% CI, 0.89-0.96; P < .001). Moreover, increasing unmet social needs was significantly associated with late-stage diagnosis above and beyond screening mammography (OR, 1.38; 95% CI, 1.01-1.89; P = .04). In this cohort study, access to screening mammography did not translate to utilization of screening mammography, increasing unmet social needs were significantly associated with lower rates of screening mammography, and those with increasing unmet social needs were more likely to present with late-stage disease. This association transcended recruitment site (SNH vs ACC), indicating that patients in either hospital setting may benefit from unmet social needs screening to overcome access to care barriers associated with late-stage disease at diagnosis.

Determinants of breast cancer screening utilization among female healthcare workers in selected hospitals in Ogbomoso, Oyo state

Objective: The study aimed at identifying the determinants of breast cancer screening among FHW in the three levels of care. FHW have greater influence on women's positive perception of breast cancer.&#x0D; Method: Descriptive cross- sectional design was employed. Purposive sampling technique was used. Data collected with the aid of validated structured questionnaire. Data analyzed using SPSS version 22 and presented in tables and graphs. The hypotheses were tested using chi square at 0.05 level of significance.&#x0D; Results: Findings revealed that 40 (18.6%) were doctors, 104 (48.4%) nurses and 71 (32.4%) others. Majority of the respondents (81.4%) had good knowledge of BSE, 73.4% had good knowledge of CBE, however, more than half of the respondents (52.6%) had poor knowledge of mammography. Age, lack of time, financial constraints, fear of positive diagnosis among others were some of the factors identified.&#x0D; Conclusion: Majority of the respondents had good knowledge. However, only the practice of BSE was good while the others were poor. Therefore, there is an urgent need for sensitization of FHW on the need to undergo the screening especially clinical breast examination and mammography

Breast cancer screening awareness among transgender individuals in Bangkok, Thailand

Background: Transgender women have higher rates of mortality associated with cancer diagnosis owing to inadequate transgender-specific cancer screening, leading to delayed diagnosis. Gender-affirming hormone therapy, age, and genetics are risk factors for breast cancer in transgender women. For transgender men, the risks were similar to those for cisgender women. However, population-based data on breast cancer screening and awareness among these sex groups are limited. Aim: This study aimed to assess breast cancer screening awareness, screening utilization, and factors associated with screening awareness among transgender individuals in Bangkok, Thailand. Methods: This multi-centered study included participants aged 18–80 years without a history of breast cancer. Data were collected using a structured questionnaire from October 2021 to October 2022. Sociodemographic data, hormonal use, gender affirming surgery, breast cancer screening awareness, utilization, and reasons for not undergoing screening were recorded. Associations with breast screening awareness were analyzed using multiple logistic regression analysis. Results: In Bangkok, 402 transgender women and 333 transgender men were surveyed. Among them, 92.8% and 64.6% of the women and men groups, respectively, had received gender-affirming hormone therapy. The women group had a higher awareness of breast cancer screening (70.9%) than the men group (60.8%). However, only 4% and 17.1% of the women and men patients, respectively, underwent breast cancer screening. A history of gender-affirming hormone therapy use was associated with a higher likelihood of breast cancer screening awareness among women. Among the men, older participants who later underwent breast-reduction surgery had a family history of breast cancer, and other types of cancer were positively associated with higher breast cancer screening awareness. Conclusion: Although awareness of breast cancer screening among urban transgender individuals is high, multiple factors limit their access to breast cancer screening.

Breast and Colorectal Cancer Screening Utilization after Hurricane María and the COVID-19 Pandemic in Puerto Rico.

Puerto Rico (PR) has faced environmental and public health challenges that could have significantly affected cancer screening access. Using administrative claims data from PR's Medicaid population, this study assessed trends in colorectal and breast cancer screening from 2016 to 2021, the impact of disasters in screening, and the absolute deficit in screening due to the pandemic. The monthly rates of claims were analyzed using Poisson regression. Significant reductions in breast and colorectal cancer screening utilization were observed. The colorectal cancer screening rate in 2017 was 77% lower a month after Hurricanes Irma and María [RRadj: 0.23; 95% CI: 0.20, 0.25] compared to the same time period in 2016. Breast cancer screening dropped 50% in November 2017 compared to November 2016 [RRadj: 0.50; 95% CI: 0.47, 0.54]. Prospectively, a recovery in utilization has been observed only for breast cancer screening. The results revealed that cancer screening utilization substantially declined after environmental disasters and the pandemic. These findings have potentially severe long-term implications for cancer health disparities and mortality in PR.

Abstract P6-08-12: Toward Comprehensive Cancer Prevention for Women Experiencing Homelessness: Demonstrating the Need for Onsite Mammography, Education, Navigation, and Cross Cancer Screenings

Abstract Background: Persons experiencing homelessness (PEH) rarely receive regular preventative health care or consistent cancer screenings. Late stage detection of cancer and barriers to care are prevalent among PEH. Novel programs such as onsite mobile mammography services represents an approach to improve breast cancer disparities among women experiencing homelessness (WEH) and allows for understanding of barriers to cancer screening amongst WEH and to develop best practices. Objectives: During onsite mobile mammography events at shelters for WEH, develop best practices for improving breast cancer screening utilization while developing approaches to increase use of other cancer screenings. Methods: In 2022, the Cleveland Clinic performed onsite mobile mammography screening events at area shelters and day centers. All seven screening events included onsite mammography, breast health education, and patient navigation. After WEH completed the education session, they completed the mammogram. Subsequently, at two events, patients had an opportunity for further consultation with an advanced practice provider (APP) including discussing additional screening tests (ex. colorectal, lung, cervical cancer) beyond mammograms with referrals as needed. Consultations also discussed approaches to reduce cancer risks with further education, referrals for dental care, and assistance securing a primary care provider (PCP). Results: At the events that included consultations, 30 patients received mammograms and 80% (n=24) of patients chose to speak with the APP. Patients seeking consultation were 21-73 years old and identified as Black/African American (n=5), White (n=16), and other (n=3). Topics of discussion included mammograms (n=24, 100%), smoking cessation referral and/or lung cancer screening (n=16, 67%), colorectal cancer screening (n=11, 46%), and cervical cancer/HPV screening (n=11, 46%). Additionally, 46% of patients (n=11) were assisted with securing a PCP and 8% of patients (n=2) were referred for dental services. Discussion: Our preliminary data demonstrate that most WEH undergoing onsite mammography screening are willing to engage in consultation to discuss additional cancer screenings with many patients eligible for additional cancer screenings. Additionally, this approach provided access to PCPs. Three best practices for cross cancer screenings include: 1) Onsite mobile mammography is an appropriate entry point for addressing breast health and also cancer screening broadly. 2) An onsite approach allows for education beyond cancer screening to provide access to primary care and other wrap around services. 3) Clinicians provide credibility and trust when they attend onsite mobile mammography events. Conclusion: Beyond breast cancer screening, WEH benefit from onsite mobile mammography, which can serve as a gateway to cross cancer screenings and access to primary care. Addressing disparities in this population should include wrap around services such as smoking cessation and connection to a PCP. Future research should examine best practices for following up with patients and completing navigation through cross cancer screenings. Citation Format: Pamela Combs, Heather M.

Breast Cancer Screening Utilization and Outcomes in Women With Neurofibromatosis Type 1

IntroductionWomen with neurofibromatosis type 1 (NF1) have up to a 5-fold increased risk for breast cancer before age 50 and a 3.5-fold increased risk of breast cancer overall. The purpose of our study was to assess breast cancer screening utilization and outcomes in this population. Patients and MethodsThis IRB approved HIPAA compliant study retrospectively assessed consecutive NF1 patients (January 2012-December 2021) with recorded clinical visits and/or breast imaging. Patient demographics, risk factors, and screening mammogram and breast magnetic resonance imaging (MRI) outcomes were recorded. Descriptive statistics were obtained and standard breast screening measures were calculated. ResultsOne hundred and eleven women (median age 43, range 30-82) were eligible for screening based on current NCCN guidelines. A total of 86% (95/111) of all patients and 80% (24/30) of patients under age 40 had at least 1 mammogram. In contrast, 28% (31/111) of all patients and 33% (25/76) of patients ages 30 to 50 had at least 1 screening MRI. Of 368 screening mammograms performed, 38 of 368 (10%) resulted in the recall, and 22 of 368 (6%) resulted in a biopsy. Of 48 screening MRIs performed, 19 of 48 (40%) short-term follow-ups and 12 of 48 (25%) biopsies were recommended. All 6 screen-detected cancers in our cohort were detected initially on screening mammograms. ConclusionResults confirm the utility and performance of screening mammography in the NF1 population. The low utilization of MRI in our cohort limits the evaluation of outcomes via this modality and suggests there may be an education or interest gap among referrers and patients regarding supplemental screening recommendations.

Determinants of breast cancer screening mammography uptake: Results from Jordan population and family health survey.

Screening for breast cancer utilizing mammography is associated with reduced advanced cancer diagnosis and reduced breast cancer mortality. We aimed to assess the lifetime history of breast cancer screening utilization for Jordanian women aged 40 and 49 years and determinants of this utilization. This paper reports the analyzed data from the seventh cycle of the Jordan Population and Family Health Survey (JPFHS). For this study, the analysis was confined to 4486 women aged between 40 and 49 years at the time of data collection who reported their nationality as Jordanian. We used multivariate logistic regression analysis to assess whether any socio-demographic variables could predict greater breast cancer screening utilization. Only 14% of all respondents aged 40-49 years reported ever having a mammogram. Results of multivariate logistic regression showed that area of residence, husband's level of education, younger age, and living in a wealthy status were strong predictors of lifetime history of breast cancer screening. This study elucidates that breast cancer screening mammography among Jordanian women has remained opportunistic and underutilized despite the efforts of national entities to promote screening and early detection of breast cancer. There is a geographic and social disparity in the utilization of mammography screening among Jordanian women.

Changes in geographic accessibility to mammography by state and rural-urban status, United States, 2006-2022.

Although mammography is widely available in the United States, differences in accessibility in rural and urban areas and changes over time are not well described. In this study, we estimated the number and proportion of women aged 45-84 years who had limited travel time-based geographic accessibility to mammography by urban-rural status and state in the contiguous United States in 2006 and 2022. The proportion of women aged 45-84 years with limited accessibility to mammography did not substantially change from 2006 (12.7%; representing 7.5 million women) to 2022 (12.2%; 8.2 million women). Accessibility to mammography varied by state, but in 10 states, more than 26% of the statewide female population aged 45-84 years had limited accessibility in 2022. This proportion was substantially higher in rural areas (50.6% overall; ≥50% in 28 states in 2022) than in urban areas (3.0% overall). Increasing accessibility to mammography could increase utilization of breast cancer screening and, potentially, improve breast cancer survival.

Socioeconomic status index is an independent determinant of breast cancer screening practices: Evidence from Eastern China.

Breast cancer is the most prevalent malignancy affecting Chinese women, and early routine screening is incredibly important for its prevention and control. This study aimed to investigate the role of socioeconomic status (SES) in female breast cancer screening practices using the composite SES index. This cross-sectional study involved 1816 women in Eastern China. Data were collected using an online self-administered questionnaire from January 2020 to May 2021. We used principal component analysis to construct the composite SES index using educational level, annual household income, and occupation. Logistic regression was used to analyze the association between the SES index and breast cancer screening utilization. Of the participants, 19.27% reported having performed breast self-examination, 12.89% reported having undergone clinical breast examination, and 3.52% reported having received mammography. The SES has a significant influence on the patronage of female breast cancer screening in Eastern China. The composite SES index was found to have a positive and significant association with breast cancer screening practices. An interaction was found between the SES index and patient characteristics, such as health awareness, marital status, and location of residence. In addition, the SES index had a positive effect on breast cancer-related knowledge. Socioeconomic inequalities existed in Eastern China and were related to breast cancer screening patronage. The composite SES index was identified as a significant determinant of breast cancer screening practices. Our results highlighted the negative impacts of socioeconomic inequities on female breast cancer screening utilization. This suggests that reducing socioeconomic inequalities in breast cancer screening requires more focused interventions and concerted outreach activities for groups with lower education levels, lower income, or lower occupational classes.

Stage-Specific Risk of Breast Cancer among Canadian Immigrant and Non-Immigrant Women.

Breast cancer screening utilization varies across immigrant and non-immigrant populations. Recent studies have also suggested that some immigrant populations in Canada present with a higher frequency of later-stage breast cancer compared to non-immigrants. Our study aimed to augment prior research by presenting breast cancer stage distributions and stage-specific breast cancer incidence rates for immigrant and non-immigrants in British Columbia, Canada. We utilized a population-based cohort of more than 1.3million women built from linked administrative health and immigration data sets. Age-standardized incidence rate ratios were generated to compare immigrant and non-immigrant groups. Poisson regression was used to assess the relative frequency of later stage diagnosis among immigrant groups compared to non-immigrants. Indian and Chinese immigrants both showed significantly lower stage I and stage II-IV incidence rates compared to non-immigrants. However, Indian immigrants showed a higher frequency of later stage tumours at diagnosis compared to non-immigrants, while in contrast Chinese immigrants showed a lower frequency of later stage tumours. Filipino immigrants showed similar stage-specific rates and stage at diagnosis compared to non-immigrants. Our findings highlight a need for continued surveillance of cancer among immigrant and non-immigrant populations and inquiry into reasons for differences in stage at diagnosis across groups.

Inequality in the Utilization of Breast Cancer Screening between Women with and without Disabilities in Taiwan: A Propensity-Score-Matched Nationwide Cohort Study.

Because of the difficulties in accessing medical care, the likelihood of receiving breast cancer screening may be low for women with disabilities. We aimed to investigate differences in the utilization of breast cancer screening among women with and without disabilities. Participants included women with and without disabilities from 2004 to 2010, and it was observed whether the participants had received a breast cancer screening during 2011 and 2012. Propensity-score matching was employed to match disabled women with non-disabled women (1:1). Data sources included the National Health Insurance Research Database, the Cancer Screening Database, and the Disability Registration File. Conditional logistic regression was performed to examine the odds ratios (ORs) that both groups would undergo breast cancer screening. The proportion of women with disabilities who received breast cancer screening was 18.33%, which was significantly lower than that of women without disabilities (25.52%) (p < 0.001). Women with dementia had the lowest probability of receiving a mammography examination (OR = 0.34; 95% CI: 0.28–0.43), followed by those with multiple disabilities (OR = 0.43; 95% CI: 0.40–0.47) and intellectual disabilities (OR = 0.45; 95% CI: 0.41–0.50). In conclusion, compared to women without disabilities, those with disabilities were less likely to undergo breast cancer screening.

Perceived neighborhood social cohesion and cervical and breast cancer screening utilization among U.S.-born and immigrant women.

Research suggests that factors beyond the individual level, such as neighborhood-level factors, warrant further investigation in explaining preventive screening utilization disparities. In addition, research shows that immigrant women, especially recent immigrants, are less likely than U.S.-born women to utilize preventive screenings. Our study examined the relationship between perceived neighborhood social cohesion and breast and cervical cancer screening utilization among U.S.-born and immigrant women. Data came from the 2018 National Health Interview Survey (NHIS). The sample for this study included 7801 women ages 21-64 without a hysterectomy. Of them, 1477 (19%) reported being born outside the United States. Logistic regression was used to examine associations of perceived neighborhood social cohesion and sociodemographic factors with the odds of screening by nativity status. Though we found no link between neighborhood social cohesion and Papanicolaou (Pap) test or mammogram utilization, our findings contribute to understanding sociodemographic barriers to and facilitators of preventive screening utilization among immigrant and U.S.-born women. Most importantly, racial/ethnic and socioeconomic disparities in Pap tests and mammogram utilization were evident among immigrant women. The disparities we identified indicate the need to target prevention messages and tailor interventions to address each group's sociodemographic characteristics and needs. Our findings also support the need to expand health insurance so that all women are covered.

Novel mapping methods to describe utilization of free breast cancer screening from a state program

IntroductionThe National Breast and Cervical Cancer Early Detection Program (NBCCEDP) is a cancer screening program whose mission is to reduce cancer morbidities for uninsured and underinsured women. A primary activity is to connect women to breast cancer screening. The eligible population and utilization of NBCCEDP screening services have never been quantified at a sub-state level, which hampers effective program evaluation. Here, the Minnesota NBCCEDP, “Sage”, serves as a case study to demonstrate novel spatial analysis methods that depict variation of screening rates at the local level.MethodsWomen who received breast cancer screening through Sage between 2011 and 2015 were geocoded (N = 74,712 screenings); analysis occurred between 2017 and 2019. We determine an eligible population using a synthetic population dataset that provides geographic residence and demographic information. We introduce a novel spatial analysis technique, spatially adaptive filters (SAFs), to create a utilization map of Sage breast screening services by Minnesota women.ResultsBetween 2011 and 2015, an average of 36,979 women per year were eligible for NBCCEDP breast cancer screening services, representing 3% of the Minnesota female population 40 and older. For Minnesota NBCCEDP eligible women, the state average breast cancer screening utilization rate was 37.2%, but varied considerably by local regions within the state (range 0% to 131%, SD = 18.7%).ConclusionsThis geospatial model estimated screening service utilization at the local level and enables Minnesota’s Sage program to target specific areas they have yet to reach. Similar programs could employ this model to direct program activities.

Comparing Different Interventions' Effects on Latinas' Screening Mammography Attainment and Participant-Driven Information Diffusion.

Evaluation of multiple community-based approaches to improve Latinas' breast cancer (BC) screening utilization has resulted in inconsistent findings. Factors contributing to this variation include heterogeneity in approaches (e.g., types of conceptual frameworks) and study quality (e.g., lack of measurement of spillover effects). This pilot study sought to clarify which approach may be most effective by evaluating the relative efficacy of two conceptual approaches using an area-level design with 145 Latinas nonadherent to U.S. Preventive Services Taskforce (USPSTF) BC screening guidelines. Each study arm included identical intervention format and duration (e.g., three group-based sessions, logistic assistance (LA) via five monthly calls and referral to free/low-cost screening programs). However, study content differed. While educate+LA addressed participants' BC prevention and screening behavior, empower+LA addressed participants' and their social networks' BC screening. After adjusting for age, insurance status, and baseline mammography intention, when compared with educate+LA participants, empower+LA participants were more likely to report obtaining mammograms, engaging more individuals about BC, initiating BC conversations in public settings, and discussing mammography specifically. Our study has important implications regarding the utility of evaluating behavioral interventions overall in terms of behavioral and spillover network effects.

The association between cognitive impairment and breast and colorectal cancer screening utilization

BackgroundUndergoing cancer screening is a debatable topic in patients with cognitive impairment. In this study, we aimed to examine the utilization and predictors of breast and colorectal cancer screening among screening eligible, cognitively impaired individuals.MethodsWe analyzed the 2018 and 2019 National Health Interview Survey data (n = 12,965 and 24,782, respectively) on individuals eligible for breast or colorectal cancer screening. We calculated the percentage of cancer screening eligible individuals who received mammogram or colonoscopy by cognitive impairment status. We used multivariable logistic regression to examine whether having a recent mammogram or colonoscopy differed by cognitive impairment status, adjusting for covariates.ResultsWe observed a significantly lower percentage of mammogram use in the screening eligible, cognitively impaired (mild or severe) versus unimpaired women. Adjusting for the covariates, the cognitively impaired women, mild (odds ratio [OR] = 0.85; p = 0.015) or severe (OR = 0.54; p < 0.001), were less likely to have had a recent mammogram compared to the cognitively unimpaired women. Although statistically non-significant, the percentage of colonoscopy use in the screening eligible, cognitively impaired individuals were slightly higher than that in the cognitively unimpaired individuals. In the regression analysis, we found the cognitively impaired men, mild (OR = 0.79; p < 0.001) or severe (OR = 0.69; p = 0.038), were less likely to have had a recent colonoscopy compared to the cognitively unimpaired men. More studies are needed to examine the multilevel factors that underpin the difference in cancer screening utilization in this vulnerable population.ConclusionOur results highlight the need for additional research to address utilization and effectiveness of cancer screening in individuals with cognitive impairment.

Factors associated with breast cancer screening intention in Kathmandu Valley, Nepal.

Breast cancer burden is increasing in low-income countries (LICs). Increasing incidence and delayed presentation of breast cancer are mainly responsible for this burden. Many women do not participate in breast cancer screening despite its effectiveness. Moreover, studies are limited on the barriers associated with low utilization of breast cancer screening in LICs. This study identified breast cancer screening behavior and factors associated with breast cancer screening intention among women in Kathmandu Valley, Nepal. A cross-sectional study was conducted among 500 women living in five municipalities of Kathmandu Valley, Nepal. Data were collected from July to September 2018, using a structured questionnaire. Interviews were conducted among women selected through proportionate random household sampling. This study was conceptualized using the theory of planned behavior, fatalism, perceived susceptibility, and perceived severity. The outcome variables included: the intention to have mammography (MMG) biennially, the intention to have clinical breast examination (CBE) annually, and the intention to perform breast self-examination (BSE) monthly. Analysis was conducted separately for each outcome variable using partial proportional odds model. Out of 500 women, 3.4% had undergone MMG biennially, 7.2% CBE annually, and 14.4% BSE monthly. Women with a positive attitude, high subjective norms, and high perceived behavioral control were more likely to have the intention to undergo all three screening methods. Similarly, women were more likely to have intention to undergo CBE and MMG when they perceived themselves susceptible to breast cancer. Conversely, women were less likely to have intention to undergo CBE when they had high fatalistic beliefs towards breast cancer. Women in this study had poor screening behavior. The practice of breast self-examination was comparatively higher than clinical breast examination and mammography. Multidimensional culturally sensitive interventions are needed to enhance screening intentions. Efforts should be directed to improve attitude, family support, and fatalistic belief towards cancer. Furthermore, the proper availability of screening methods should be ensured while encouraging women to screen before the appearance of symptoms.

Temporal trends and regional disparities in cancer screening utilization: an observational Swiss claims-based study

BackgroundWe examined colorectal, breast, and prostate cancer screening utilization in eligible populations within three data cross-sections, and identified factors potentially modifying cancer screening utilization in Swiss adults.MethodsThe study is based on health insurance claims data of the Helsana Group. The Helsana Group is one of the largest health insurers in Switzerland, insuring approximately 15% of the entire Swiss population across all regions and age groups. We assessed proportions of the eligible populations receiving colonoscopy/fecal occult blood testing (FOBT), mammography, or prostate-specific antigen (PSA) testing in the years 2014, 2016, and 2018, and calculated average marginal effects of individual, temporal, regional, insurance-, supply-, and system-related variables on testing utilization using logistic regression.ResultsOverall, 8.3% of the eligible population received colonoscopy/FOBT in 2014, 8.9% in 2016, and 9.2% in 2018. In these years, 20.9, 21.2, and 20.4% of the eligible female population received mammography, and 30.5, 31.1, and 31.8% of the eligible male population had PSA testing. Adjusted testing utilization varied little between 2014 and 2018; there was an increasing trend of 0.8% (0.6–1.0%) for colonoscopy/FOBT and of 0.5% (0.2–0.8%) for PSA testing, while mammography use decreased by 1.5% (1.2–1.7%). Generally, testing utilization was higher in French-speaking and Italian-speaking compared to German-speaking region for all screening types. Cantonal programs for breast cancer screening were associated with an increase of 7.1% in mammography utilization. In contrast, a high density of relevant specialist physicians showed null or even negative associations with screening utilization.ConclusionsVariation in cancer screening utilization was modest over time, but considerable between regions. Regional variation was highest for mammography use where recommendations are debated most controversially, and the implementation of programs differed the most.
