Attitudes to colorectal cancer screening among ethnic minority groups in the UK

Access to colorectal cancer screening for Pakistani immigrants in Norway - a qualitative study

BACKGROUND

The Norwegian colorectal cancer (CRC) screening program started in May 2022. Inequalities in CRC screening participation are a challenge, and we expect that certain groups, such as immigrants, are at risk of non-participation. Prior to the start of the national screening program, a pilot study showed lower participation rates in CRC screening among immigrants from Pakistan. These immigrants are a populous group with a long history in Norway and yet have a relatively low participation rate also in other cancer screening programs. The purpose of this study was to identify and explore perspectives and factors influencing CRC screening participation among immigrants from Pakistan in Norway.

MATERIALS AND METHODS

In this study we used a qualitative study design and conducted 12 individual interviews with Pakistani immigrants aged between 50 and 65 years. The participants varied in terms of gender, age, education, work, residence time in Norway and familiarity with the Norwegian language and culture. We performed thematic analysis with health literacy as a theoretical framework to understand Pakistani immigrants' perspectives on CRC screening.

RESULTS

We identified four main themes: Health-related knowledge, the health care system, screening, and social factors. Within these themes we identified several factors that affect Pakistani immigrants' accessibility to CRC screening. These factors included knowledge of the causes and development of cancer, sources of health-related information, the general practitioner's role, understanding of screening and the intention behind it, language skills and religious beliefs.

CONCLUSION

There are many factors influencing Pakistani immigrants' decision of participation in CRC screening. The roles of the general practitioner and adult children are particularly important. Key elements to improve accessibility to CRC screening and enable informed participation for Pakistani immigrants are measures that improve personal and organizational health literacy.

Investigating inequalities in men's health: a literature review

As part of a project to review the delivery of healthcare services in Torbay and South Devon, England, the author undertook a literature review focusing on the specialty of men's health. Men have a shorter life expectancy than women and this discrepancy is particularly pronounced in areas of social deprivation such as those found in the coastal and rural communities of the author's locality. The concept of men's health is complex, and this literature review identified five main themes that can have a significant influence on the delivery of healthcare services for men: masculinity, ethnicity, mental health, relevance of place, and access to services. In this article, the author discusses these themes and considers approaches that could be used to improve the provision of men's healthcare.

"Sorry for laughing, but it's scary": humor and silence in discussions of Colorectal Cancer with Urban American Indians

BACKGROUND

Given high rates of cancer mortality in Native communities, we examined how urban American Indian and Alaska Native elders talk about colorectal cancer (CRC) and CRC screening.

METHODS

We conducted seven focus groups with a total of 46 participants in two urban clinics in the Pacific Northwest to assess participant awareness, perceptions, and concerns about CRC and CRC screening. Using speech codes theory, we identified norms that govern when and how to talk about CRC in this population.

RESULTS

Our analyses revealed that male participants often avoided screening because they perceived it as emasculating, whereas women often avoided screening because of embarrassment and past trauma resulting from sexual abuse. Both men and women used humor to mitigate the threatening nature of discussions about CRC and CRC screening.

CONCLUSIONS

We offer our analytic results to assist others in developing culturally appropriate interventions to promote CRC screening among American Indians and Alaska Natives.

Systematic review of randomised controlled trials on interventions aimed at promoting colorectal cancer screening amongst ethnic minorities

OBJECTIVES

Significant disparities exist between different ethnic groups when it comes to participation in colorectal cancer (CRC) screening programmes. A variety of interventions have been proposed to improve participation rates of ethnic minorities for CRC screening. This systematic review aims to appraise the evidence available from published randomised controlled trials (RCTs) and to identify effective interventions aimed at promoting CRC screening amongst underserved ethnic minorities.

DESIGN

We searched EmBASE, Medline, PsychInfo, Scopus and CINAHL for RCTs that analysed interventions to promote CRC screening in all ethnic minorities. CRC screening was measured as documented or self-reported screening rates. The protocol of this study was registered prospectively on PROSPERO with the registration number CRD42020216384.

RESULTS

We identified 42 relevant RCT articles, out of 1805 articles highlighted by the initial search. All except one were conducted in the US. The most frequently studied ethnic groups were African-Americans (33%), East Asians (30%), and Hispanics/Latinos (23%). In total, 7/42 (16%) RCTs had multiple arms. Interventions mainly intended to educate (52%), provide patient navigation services (21%), or provide a combination of these interventions (19%). We demonstrate that combination methods are most effective.

CONCLUSION

Many RCTs, mostly in the US, have trialed interventions aimed to increase CRC screening uptake amongst ethnic minorities to varying success. We conclude that using a combination of methods with patient navigation, education, and cultural tailoring is most effective at increasing CRC screening uptake amongst ethnic minorities. This highlights that multiple factors may hinder CRC screening and finding a one-size-fits-all solution that can be reliably implemented among different cultures and countries may be complex.

Barriers and Facilitators to Colorectal Cancer Screening in South Asian Immigrants: A Systematic Review

OBJECTIVE

The purpose of this systematic review is to broaden our knowledge of colorectal cancer (CRC) screening in South Asian immigrants living in Canada, Hong Kong, the United Kingdom, the United States, and Australia by determining the barriers and facilitators and examining interventions for CRC screening.

METHODS

A literature search of PubMed, Ovid Medline, and Google was conducted using South Asian, Asian Indians, cancer screening, colorectal neoplasm, early detection of cancer, and mass screening as search terms. The review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Only research articles written in English from 2000 to July 2022 were collected. Inclusion criteria included all English-language articles, the South Asian population, and either reporting barriers, facilitators, interventions, or recommendations for CRC screening. Exclusion criteria included all articles that did not meet inclusion criteria or were duplicates. A total of 32 articles were deemed eligible for inclusion and were retrieved for further analysis. The countries of origin in the articles reviewed included Canada, Hong Kong, the United Kingdom, the United States, and Australia.

RESULTS

In general, the studies indicated that South Asians have low CRC screening rates. The most common barriers reported were poor knowledge/awareness of CRC and CRC screening, lack of physician recommendation, psychological factors (e.g., fear, anxiety, and shame), cultural/religious factors, and sociodemographic factors (language barrier, lower income, and female gender). The most important facilitator reported was the physician's recommendation. Six intervention studies of either education or organized screening programs were shown to have a positive influence by increasing knowledge and improving attitudes toward CRC screening.

CONCLUSION

Of the limited number of studies identified, the population categorized as South Asians was largely heterogeneous, including a diversity of ethnicities. Although the rates of CRC among South Asians were relatively low, there remain many cultural barriers to the awareness of and screening for CRC in this population. Further research in this population is needed to better identify the factors related to CRC in individuals of South Asian ethnicity. Recommending CRC screening by physicians and mid-level providers and educating patients with culturally sensitive programs and materials are important to increase knowledge and awareness of CRC and CRC screening.

Exploration of Malaysian Stakeholders View on Barriers to and Facilitators of Colorectal Cancer Screening Among Older Population

According to the Malaysian National Cancer Registry (MNCR), more than 70% of colorectal cancer (CRC) cases in Malaysia are presented in the advanced stages of the disease, leading to poor survival rates while taxing the health care system. This study aims to explore the barriers to and facilitators of CRC screening uptake in the perspectives of the general population, health care providers, and policymakers. In-depth, semi-structured interviews were conducted with 25 purposively sampled respondents comprising general population above the age of 40, health care providers, and policymakers. Commonly reported barriers to CRC screening included psychological, poor knowledge and awareness, lack of physicians' recommendation, and inadequate implementation of CRC-related campaigns at systemic level. Facilitating factors for CRC screening included family support and family history of CRC. A comprehensive understanding of barriers and facilitators is relevant for designing an effective intervention and policy to increase CRC screening rates in Malaysia.

Participation in Colorectal Cancer Screening among Migrants and Non-Migrants in Germany: Results of a Population Survey

Colorectal cancer screening can contribute to reducing colorectal cancer incidence and mortality. Findings on disparities in the utilization of colorectal cancer screening between migrants and non-migrants have been inconsistent, with some studies reporting lower, and some higher utilization among migrants. The aim of the present study was to examine potential disparities in fecal occult blood testing and colonoscopy among migrants in Germany. Data from a population survey on 11,757 men and women aged ≥50 years is used. Using multivariable logistic regression, the utilization of fecal occult blood testing and colonoscopy was compared between non-migrants, migrants from EU countries and migrants from non-EU countries, adjusting for socio-economic factors and also taking into account intersectional differences by sex and age. The study shows that migrants from the EU (adjusted OR = 0.73; 95%-CI: 0.57, 0.94) and from non-EU countries (adjusted OR = 0.39; 95%-CI: 0.31, 0.50) were less likely to utilize fecal occult blood testing than non-migrants. No disparities for the use of colonoscopy were observed. The findings are in line with studies from other countries and can be indicative of different barriers migrants encounter in the health system. Adequate strategies taking into account the diversity of migrants are needed to support informed decision-making among this population group.

Inequalities in cancer screening, prevention and service engagement between UK ethnic minority groups

More people in the UK are living with cancer than ever before. With an increasingly ethnically diverse population, greater emphasis must be placed on understanding factors influencing cancer outcomes. This review seeks to explore UK-specific variations in engagement with cancer services in minority ethnic groups and describe successful interventions. The authors wish to highlight that, despite improvement to engagement and education strategies, inequalities still persist and work to improve cancer outcomes across our communities still needs to be prioritised. There are many reasons why cancer healthcare inequities exist for minority communities, reported on a spectrum ranging from cultural beliefs and awareness, through to racism. Strategies that successfully enhanced engagement included language support; culturally-sensitive reminders; community-based health workers and targeted outreach. Focusing on the diverse city of Leicester the authors describe how healthcare providers, researchers and community champions have worked collectively, delivering targeted community-based strategies to improve awareness and access to cancer services.

Reasons for intending to accept or decline kidney cancer screening: thematic analysis of free text from an online survey

OBJECTIVES

Kidney cancer has been identified as a disease for which screening might provide significant benefit for patients. The aim of this study was to understand in detail the facilitators and barriers towards uptake of a future kidney cancer screening programme, and to compare these across four proposed screening modalities.

DESIGN

An online survey including free-text responses.

SETTING

UK PARTICIPANTS: 668 adults PRIMARY AND SECONDARY OUTCOME MEASURES: The survey assessed participants' self-reported intention to take-up kidney cancer screening with four different test methods (urine test, blood test, ultrasound scan and low-dose CT). We conducted thematic analysis of 2559 free-text comments made within the survey using an inductive approach.

RESULTS

We identified five overarching themes that influenced screening intention: 'personal health beliefs', 'practicalities', 'opinions of the test', 'attitudes towards screening' and 'cancer apprehension'. Overall, participants considered the tests presented as simple to complete and the benefits of early detection to outweigh any drawbacks to screening. Dominant facilitators and barriers varied with patterns of intention to take up screening across the four tests. Most intended to take up screening by all four tests, and for these participants, screening was seen as a positive health behaviour. A significant minority were driven by practicalities and the risks of the tests offered. A smaller proportion intended to reject all forms of screening offered, often due to fear or worry about results and unnecessary medical intervention or a general negative view of screening.

CONCLUSIONS

Most individuals would accept kidney cancer screening by any of the four test options presented because of strong positive attitudes towards screening in general and the perceived simplicity of the tests. Providing information about the rationale for screening in general and the potential benefits of early detection will be important to optimise uptake among uncertain individuals.

Preferences for different diagnostic modalities to follow up abnormal colorectal cancer screening results: a hypothetical vignette study

OBJECTIVES

In England, a significant proportion of people who take part in the national bowel cancer screening programme (BCSP) and have a positive faecal occult blood test (FOBt) result, do not attend follow-up colonoscopy (CC). The aim of this study was to investigate differences in intended participation in a follow-up investigation by diagnostic modality offered including CC, CT colonography (CTC) or capsule endoscopy (CE).

SETTING

We performed a randomised online experiment with individuals who had previously completed an FOBt as part of the English BCSP.

METHODS

Participants (n=953) were randomly allocated to receive one of three online vignettes asking participants to imagine they had received an abnormal FOBt result, and that they had been invited for a follow-up test. The follow-up test offered was either: CC (n=346), CTC (n=302) or CE (n=305). Participants were then asked how likely they were to have their allocated test or if they refused, either of the other tests. Respondents were also asked to cite possible emotional and practical barriers to follow up testing. Multivariable logistic regression models were used to investigate intentions.

RESULTS

Intention to have the test was higher in the CTC group (96.7%) compared with the CC group (91.8%; OR 2.64; 95% CI 1.22 to 5.73). CTC was considered less 'off-putting' (OR 0.66, 95% CI 0.47 to 0.94) and less uncomfortable compared with CC (OR 0.51, 95% CI 0.34 to 0.77). For those who did not intend to have the test they were offered, CE (39.7%) or no investigation (34.5%) was preferable to CC (8.6%) or CTC (17.2%).

CONCLUSIONS

Alternative tests have the potential to increase attendance at diagnostic follow-up appointments.

Barriers to flexible sigmoidoscopy colorectal cancer screening in low uptake socio-demographic groups: A systematic review

OBJECTIVE

To synthesise qualitative evidence related to barriers and facilitators of flexible sigmoidoscopy screening (FSS) intention and uptake, particularly within low socio-demographic uptake groups. FSS uptake is lower amongst women, lower socio-economic status (SES), and Asian ethnic groups within the United Kingdom (UK) and United States of America.

METHODS

A total of 12 168 articles were identified from searches of four databases: EMBASE, MEDLINE, PsycINFO and Web of Science. Eligibility criteria included: individuals eligible to attend FSS and empirical peer-reviewed studies that analysed qualitative data. The Critical Appraisal Skills Program tool evaluated the methodological quality of included studies, and thematic synthesis was used to analyse the data.

RESULTS

Ten qualitative studies met the inclusion criteria. Key barriers to FSS intention and uptake centred upon procedural anxieties. Women, including UK Asian women, reported shame and embarrassment, anticipated pain, perforation risk, and test preparation difficulties to elevate anxiety levels. Religious and cultural-influenced health beliefs amongst UK Asian groups were reported to inhibit FSS intention and uptake. Competing priorities, such as caring commitments, particularly impeded women's ability to attend certain FSS appointments. The review identified a knowledge gap concerning factors especially associated with FSS participation amongst lower SES groups.

CONCLUSIONS

Studies mostly focussed on barriers and facilitators of intention to participate in FSS, particularly within UK Asian groups. To determine the barriers associated with FSS uptake, and further understand how screening intention translates to behaviour, it is important that future qualitative research is equally directed towards factors associated with screening behaviour.

A family-based multimedia intervention to enhance the uptake of colorectal cancer screening among older South Asian adults in Hong Kong: a study protocol for a cluster randomized controlled trial

BACKGROUND

Colorectal cancer (CRC) screening, such as fecal occult blood test (FOBT), is an effective way to prevent CRC, one of the most common cancers worldwide. However, studies found that South Asian ethnic minorities tend not to utilize CRC screening, whose importance on CRC prevention shall be educated among those from ethnic minorities, especially older adults. The purpose of this study is to develop and implement a family-based, multimedia intervention to augment the knowledge of CRC prevention among older South Asian adults in Hong Kong and enhance their motivation for undergoing FOBT. The acceptability and effectiveness of the intervention will be assessed using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework.

METHODS

A cluster randomized controlled trial will be carried out. Three hundred and twenty South Asian dyads, comprising an older adult aged between 50 and 75 and a younger family member aged between 18 and 49, will be recruited in ten districts in Hong Kong through community organizations that provide support services for South Asians in local communities. Dyads will be randomly allocated to either the intervention or wait-list control group. Intervention dyads will receive intervention, whose contents are based on the health belief model, via multiple forms of media including PowerPoint presentation, video clip and health information booklet. Control dyads will receive intervention after post-intervention data are collected. For dyads in both groups, an appointment with a family doctor will be arranged for those willing to undergo FOBT. Outcomes will be assessed at baseline and post-intervention. Data will be analysed using the Generalised Linear Models Procedure in an intention-to-treat manner.

DISCUSSION

Findings of this study will provide evidence of the benefits of utilizing multimedia and family-based approaches in intervention development to enhance the effectiveness of health promotion interventions for ethnic minorities. Further, the findings would provide reference to the potential incorporation of the intervention in the existing support services for South Asian ethnic minorities in local communities.

TRIAL REGISTRATION

This trial is registered at the ISRCTN Registry ( ISRCTN72829325 ) on 19th July 2018.

Market segmentation tools provide insights into demographic variations in bowel cancer screening uptake

Background

The National Health Service Bowel Cancer Screening Programme (NHS BCSP) aims to detect individuals who have precancerous polyps or early stage cancer, when it is easier to treat. To be effective, a screening uptake of at least 52% is required. Variations in uptake by demographic characteristic are reported and the aim of this study was to better understand who participates in the NHS BCSP, to inform action to address inequalities in screening uptake.

Methods

Invitation-level data for the Derbyshire population were supplied by the NHS BCSP Eastern Hub for the period 1 April 2014 to 31 March 2016. Data were linked by postal code to the Mosaic Public Sector Segmentation tool. Descriptive analysis using 14 groups and 61 types within Mosaic was undertaken to offer insight into the demographic, lifestyle and behavioural traits of people living in small geographies against their screening uptake, with a particular focus on identifying population groups with an uptake below 52% and so at risk of health inequalities.

Results

180 176 screening invitations were dispatched with an overall uptake of 60.55%. Six Mosaic groups have an uptake below the 52% acceptable level: urban cohesion, rental hubs, transient renters, family basics, vintage value and municipal tenants. These groups are characterised by high levels of social-rented accommodation, multicultural urban communities and transient populations.

Conclusion

Segmentation tools offer an effective way to generate novel insights into bowel cancer screening uptake and develop tailored strategies for working with identified communities to increase participation.

A Cross-Sectional Assessment of Literacy and Awareness, Attitudes, and Beliefs About Colorectal Cancer and Its Screening in Riyadh Region

This study aims to explore the association between functional health literacy and awareness for, beliefs, and attitudes of patients with colorectal cancer (CRC) and CRC screening test in Riyadh, Saudi Arabia. A total of 256 participants from two different tertiary level hospitals in Riyadh, Saudi Arabia were recruited in this study. The participants were interviewed by a trained researcher between October and December 2015. All respondents answered a three-part questionnaire which included demographic data, questions related to CRC awareness, attitude, behaviour, and short Test of Functional Health Literacy in Adults (STOFHLA). More than half of the participants had an inadequate awareness of functional health literacy skills (FHLS), 16.4 % had marginal of FHLS awareness and 17.6 % had adequate awareness about FHLS as assessed by the STOFHLA. Overall, the majority of the participants in both marginal and adequate aware groups showed a limited awareness about colorectal cancer screening and testing. A significant association was found on awareness of the patients about frequencies that they should have been tested for colorectal cancer and functional health literacy. No significant association was found between functional health literacy as assessed by STOFHLA and concerns of Faecal Occult Blood Test (FOBT) (p = 0.384) and sigmoidoscopy or colonoscopy might cause embarrassment (p = 0.089), harm (p = 0.917), and pain (p = 0.849). The present study revealed a low level of health literacy among Saudi adults in Riyadh region. Although the level of literacy was low, the bigger concern is that of the poor awareness and beliefs of Saudi adults about CRC and CRC screening.

What is it about a cancer diagnosis that would worry people? A population-based survey of adults in England

Background

Surveys indicate quite high prevalence of cancer worry in the general population, but little is known about what it is about cancer that worries people. A better understanding of the origins of cancer worry may help elucidate previously found inconsistencies in its behavioural effect on cancer prevention, screening uptake, and help-seeking for symptoms. In this study, we explore the prevalence and population distribution of general cancer worry and worries about specific aspects of cancer previously identified.

Methods

A population-based survey of 2048 English adults (18–70 years, April–May 2016), using face-to-face interviews to assess demographic characteristics, general cancer worry and twelve sources of cancer worry (adapted from an existing scale), including the emotional, physical, and social consequences of a diagnosis.

Results

In general, a third of respondents (37%) never worried about cancer, 57% worried occasionally/sometimes, and 6% often/very often. In terms of specific worries, two thirds would be ‘quite a bit’ or ‘extremely’ worried about the threat to life and emotional upset a diagnosis would cause. Half would worry about surgery, radiotherapy, chemotherapy, and loss of control over life. Worries about the social consequences were less commonly anticipated: just under half would worry about financial problems or their social roles, and a quarter would be worried about effects on identity, important relationships, gender role, and sexuality. Women and younger people reported more frequent worry about getting cancer, and would be more worried about the emotional, physical, and social consequences of a cancer diagnosis (p < .001). Those from ethnic minority backgrounds reported less frequent worry about getting cancer than their white counterparts, but would be equally worried about the emotional and physical impact of a cancer diagnosis, and worried more about the social consequences of a cancer diagnosis (p < .05).

Conclusions

The majority of English adults worry at least occasionally about getting cancer, and would be most worried about the emotional and physical impact of a cancer diagnosis. Distinguishing between the various worries that cancer can evoke may help inform efforts to allay undue worries in those who are deterred by them from engaging with cancer prevention and early detection.

Cross-cultural survey development: The Colon Cancer Screening Behaviors Survey for South Asian populations

OBJECTIVE

The objective of this work was to develop a survey that considered cultural relevance and diversity of South Asian populations, with the aim of describing or predicting factors that influence colorectal cancer screening intention and adherence. The scientifically rigorous approach for survey development informed the final phase of an exploratory mixed method study. This initial survey was later cross-culturally translated and adapted into the Urdu language, and thereafter, items were cognitively tested for conceptual relevance among South Asian immigrants.

RESULTS

The initial development of the Colon Cancer Screening Behaviours Survey for South Asian populations was completed using a number of steps. Development involved: the identification of key concepts and conceptual model; literature search for candidate measures and critical appraisal; and, expert consultation to select relevant measures. Five published surveys included measures that covered concepts relevant to South Asians and colorectal cancer screening behaviours. However, measures from these surveys missed content that emerged through parallel field work with South Asians, and additions were required along with item modifications. In the final stage, cross-cultural translation and adaptation into Urdu, and cognitive testing were completed. Future research will require an examination of proposed relationships, and psychometric testing of measures in the survey.

Migrant's access to preventive health services in five EU countries

Background

Preventive health services (PHSs) form part of primary healthcare with the aim of screening to prevent disease. Migrants show significant differences in lifestyle, health beliefs and risk factors compared with the native populations. This can have a significant impact on migrants’ access to health systems and participation in prevention programmes. Even in countries with widely accessible healthcare systems, migrants’ access to PHSs may be difficult. The aim of the study was to compare access to preventive health services between migrants and native populations in five European Union (EU) countries.

Methods

Information from Health Interview Surveys of Belgium, Italy, Malta, Portugal and Spain were used to analyse access to mammography, Pap smear tests, colorectal cancer screening and flu vaccination among migrants. The comparative risk of not accessing PHSs was calculated using a mixed-effects multilevel model, adjusting for potential confounding factors (sex, education and the presence of disability). Migrant status was defined according to citizenship, with a distinction made between EU and non-EU countries.

Results

Migrants, in particular those from non-EU countries, were found to have poorer access to PHSs. The overall risk of not reporting a screening test or a flu vaccination ranged from a minimum of 1.8 times (colorectal cancer screening), to a high of 4.4 times (flu vaccination) for migrants. The comparison among the five EU countries included in the study showed similarities, with particularly limited access recorded in Italy and in Belgium for non-EU migrants.

Conclusions

The findings of this study are in accordance with evidence from the scientific literature. Poor organization of health services, in Italy, and lack of targeted health policies in Belgium may explain these findings. PHSs should be responsive to patient diversity, probably more so than other health services. There is a need for diversity-oriented, migrant-sensitive prevention. Policies oriented to removing impediments to migrants’ access to preventive interventions are crucial, to encourage more positive action for those facing the risk of intersectional discrimination.

Testing innovative strategies to reduce the social gradient in the uptake of bowel cancer screening: a programme of four qualitatively enhanced randomised controlled trials

Background

Bowel cancer screening reduces cancer-specific mortality. There is a socioeconomic gradient in the uptake of the English NHS Bowel Cancer Screening Programme (BCSP), which may lead to inequalities in cancer outcomes.

Objective

To reduce socioeconomic inequalities in uptake of the NHS BCSP’s guaiac faecal occult blood test (gFOBt) without compromising uptake in any socioeconomic group.

Design

Workstream 1 explored psychosocial determinants of non-uptake of gFOBt in focus groups and interviews. Workstream 2 developed and tested four theoretically based interventions: (1) ‘gist’ information, (2) a ‘narrative’ leaflet, (3) ‘general practice endorsement’ (GPE) and (4) an ‘enhanced reminder’ (ER). Workstream 3 comprised four national cluster randomised controlled trials (RCTs) of the cost-effectiveness of each intervention.

Methods

Interventions were co-designed with user panels, user tested using interviews and focus groups, and piloted with postal questionnaires. RCTs compared ‘usual care’ (existing NHS BCSP invitations) with usual care plus each intervention. The four trials tested: (1) ‘gist’ leaflet (n = 163,525), (2) ‘narrative’ leaflet (n = 150,417), (3) GPE on the invitation letter (n = 265,434) and (4) ER (n = 168,480). Randomisation was based on day of mailing of the screening invitation. The Index of Multiple Deprivation (IMD) score associated with each individual’s home address was used as the marker of socioeconomic circumstances (SECs). Change in the socioeconomic gradient in uptake (interaction between treatment group and IMD quintile) was the primary outcome. Screening uptake was defined as the return of a gFOBt kit within 18 weeks of the invitation that led to a ‘definitive’ test result of either ‘normal’ (i.e. no further investigation required) or ‘abnormal’ (i.e. requiring referral for further testing). Difference in overall uptake was the secondary outcome.

Results

The gist and narrative trials showed no effect on the SECs gradient or overall uptake (57.6% and 56.7%, respectively, compared with 57.3% and 58.5%, respectively, for usual care; allp-values > 0.05). GPE showed no effect on the gradient (p = 0.5) but increased overall uptake [58.2% vs. 57.5% in usual care, odds ratio (OR) = 1.07, 95% confidence interval (CI) 1.04 to 1.10;p < 0.0001]. ER showed a significant interaction with SECs (p = 0.005), with a stronger effect in the most deprived IMD quintile (14.1% vs. 13.3% in usual care, OR = 1.11, 95% CI 1.04 to 1.20;p = 0.003) than the least deprived (34.7% vs. 34.9% in usual care OR = 1.00, 95% CI 0.94 to 1.06;p = 0.98), and higher overall uptake (25.8% vs. 25.1% in usual care, OR = 1.07, 95% CI 1.03 to 1.11;p = 0.001). All interventions were inexpensive to provide.

Limitations

In line with NHS policy, the gist and narrative leaflets supplemented rather than replaced existing NHS BCSP information. This may have undermined their effect.

Conclusions

Enhanced reminder reduced the gradient and modestly increased overall uptake, whereas GPE increased overall uptake but did not reduce the gradient. Therefore, given their effectiveness and very low cost, the findings suggest that implementation of both by the NHS BCSP would be beneficial. The gist and narrative results highlight the challenge of achieving equitable delivery of the screening offer when all communication is written; the format is universal and informed decision-making mandates extensive medical information.

Future work

Socioculturally tailored research to promote communication about screening with family and friends should be developed and evaluated.

Factors influencing participation in colorectal cancer screening-a qualitative study in an ethnic and socio-economically diverse inner city population

Background

Ethnic and socio‐economic inequalities have been reported in the uptake of colorectal cancer (CRC) screening. This study aimed to explore the factors affecting CRC screening participation in an ethnically and socio‐economically diverse inner city population.

Methods

Semi‐structured interviews were undertaken with 50 people aged 55–74 years, recruited from GP practices in south‐east London. Participants were from Black African (n=13), Black Caribbean (n=15), White British (n=17), Black other (n=2) and White other (n=3) backgrounds. Participants' socio‐economic status (SES) was assessed using a combined measure of educational attainment, housing tenure and car ownership. Participants' SES varied although there were more participants from less deprived backgrounds than those from more deprived backgrounds. The interview topic guide was informed by the Theoretical Domains Framework. Interviews were recorded, transcribed and analysed using framework analysis.

Findings

Lack of awareness of CRC screening was a barrier for all participants. There were also some notable group differences by ethnicity and SES. Cancer fear was a barrier for White British participants of varying SES. Misunderstanding instructions for completing the guaiac faecal occult blood test (gFOBt) was a barrier for people of low SES regardless of ethnicity. For Black African and Black Caribbean participants, of any SES, religious faith and a perceived civic duty to participate in screening encouraged participation.

Discussion and conclusions

This is the first study to provide detailed information on the separate views of Black African and Black Caribbean participants about screening. Consideration of ethnicity and SES together also allowed us to identify pertinent barriers for particular groups that can be targeted to improve access to screening for those who wish to take part.

Systematic Review and Meta-study Synthesis of Qualitative Studies Evaluating Facilitators and Barriers to Participation in Colorectal Cancer Screening

Screening reduces the incidence, morbidity, and mortality of colorectal cancer, yet participation tends to be low. We undertook a systematic review and meta-study synthesis of qualitative studies to identify facilitators and barriers to colorectal cancer screening participation. We searched major bibliographic databases for records published in all languages from inception to February 2015. Included primary studies that elicited views and perceptions towards colorectal cancer screening were appraised for relevance and quality. We used a two-stage synthesis to create an interpretation of colorectal cancer screening decisions grounded in primary studies; a thematic analysis to group themes and systematically compare studies and a meta-synthesis to generate an expanded theory of colorectal cancer screening participation. Ninety-four studies were included. The decision to participate in colorectal cancer screening depended on an individual's awareness of colorectal cancer screening. Awareness affected views of cancer, attitudes towards colorectal cancer screening modalities, and motivation for screening. Factors mediating awareness included public education to address misconceptions, primary care physician efforts to recommend screening, and the influence of friends and family. Specific barriers to participation in populations with lower participation rates included language barriers, logistical challenges to attending screening tests, and cultural beliefs. This study identifies key barriers, facilitators, and mediators to colorectal cancer screening participation. Cancer Epidemiol Biomarkers Prev; 25(6); 907-17. ©2016 AACR.

Cancer screening behaviours among South Asian immigrants in the UK, US and Canada: a scoping study

South Asian (SA) immigrants settled in the United Kingdom (UK) and North America [United States (US) and Canada] have low screening rates for breast, cervical and colorectal cancers. Incidence rates of these cancers increase among SA immigrants after migration, becoming similar to rates in non-Asian native populations. However, there are disparities in cancer screening, with low cancer screening uptake in this population. We conducted a scoping study using Arksey & O'Malley's framework to examine cancer screening literature on SA immigrants residing in the UK, US and Canada. Eight electronic databases, key journals and reference lists were searched for English language studies and reports. Of 1465 identified references, 70 studies from 1994 to November 2014 were included: 63% on breast or cervical cancer screening or both; 10% examined colorectal cancer screening only; 16% explored health promotion/service provision; 8% studied breast, cervical and colorectal cancer screening; and 3% examined breast and colorectal cancer screening. A thematic analysis uncovered four dominant themes: (i) beliefs and attitudes towards cancer and screening included centrality of family, holistic healthcare, fatalism, screening as unnecessary and emotion-laden perceptions; (ii) lack of knowledge of cancer and screening related to not having heard about cancer and its causes, or lack of awareness of screening, its rationale and/or how to access services; (iii) barriers to access including individual and structural barriers; and (iv) gender differences in screening uptake and their associated factors. Findings offer insights that can be used to develop culturally sensitive interventions to minimise barriers and increase cancer screening uptake in these communities, while recognising the diversity within the SA culture. Further research is required to address the gap in colorectal cancer screening literature to more fully understand SA immigrants' perspectives, as well as research to better understand gender-specific factors that influence screening uptake.

Comparison Study of Uptake of Colorectal Cancer Testing between Ethnic Minorities and the General Population in Hong Kong

BACKGROUND

Colorectal cancer (CRC) is one of the most common cancers. This study aimed to compare the uptake of CRC testing in the general public and in ethnic minorities in Hong Kong.

MATERIALS AND METHODS

This cross-sectional survey covered 2,327 South Asian and Chinese adults aged over 50, recruited from two separate studies. A structured questionnaires were administered by research staff over the telephone or in face- to-face interviews.

RESULTS

The uptake rate of CRC testing among South Asians was significantly lower than that of the general population in Hong Kong. Factors associated with the uptake rate were health professional's recommendation, perception of regular visits to doctor, use of complementary therapy, ethnicity, perceived susceptibility to cancer, presence of chronic illness, and education level. In addition, a significant interaction (p<0.05) between ethnicity and health professionals' recommendations was found, after adjustment for the main independent factors identified.

CONCLUSIONS

Older people with lower educational attainment, without chronic illness and those have lower perceived susceptibility to cancer may be targeted for CRC testing promotion in the society. In addition, health professionals can play a highly influential role in promoting such testing, particularly among ethnic minorities.

Understanding low colorectal cancer screening uptake in South Asian faith communities in England--a qualitative study

Background

Colorectal cancer screening uptake within the South Asian population in England is approximately half that of the general population (33 % vs 61 %), and varies by Muslim (31.9 %), Sikh (34.6 %) and Hindu (43.7 %) faith background. This study sought to explore reasons for low uptake of CRC screening in South Asian communities and for the variability of low uptake between three faith communities; and to identify strategies by which uptake might be improved.

Methods

We interviewed 16 ‘key informants’ representing communities from the three largest South Asian faith backgrounds (Islam, Hinduism and Sikhism) in London, England.

Results

Reasons for low colorectal cancer screening uptake were overwhelmingly shared across South Asian faith groups. These were: limitations posed by written English; limitations posed by any written language; reliance on younger family members; low awareness of colorectal cancer and screening; and difficulties associated with faeces. Non-written information delivered verbally and interactively within faith or community settings was preferred across faith communities.

Conclusions

Efforts to increase accessibility to colorectal cancer screening in South Asian communities should use local language broadcasts on ethnic media and face-to-face approaches within community and faith settings to increase awareness of colorectal cancer and screening, and address challenges posed by written materials.

The impact of supplementary narrative-based information on colorectal cancer screening beliefs and intention

Background

The potential benefits of colorectal cancer screening are limited by low uptake. This study tested whether providing narrative accounts of the colorectal cancer (CRC) screening experience positively affected beliefs about CRC screening and intention to be screened.

Methods

4125 adults aged 45-59.5 years, from three general practices in England, were randomised to be sent the standard information on CRC screening or the standard information plus a narrative-based leaflet describing CRC screening experiences. Both groups were asked to complete and return a questionnaire on beliefs about CRC screening after reading the study materials. Between-group differences on responses were assessed with t-tests. A mediation analysis then addressed the mediating role of CRC screening beliefs on the group and intention relationship.

Results

Relative to the standard information group (n = 590), the standard information plus narrative leaflet group (n = 631) showed higher perceived vulnerability to CRC, higher perceived test response efficacy, a stronger belief that the screening test would provide peace of mind and less disgust with the test procedure. There were no between group differences on perceived self-efficacy or the understanding that the screening test should be done in the absence of symptoms. Respondents who received the additional narrative leaflet reported significantly higher CRC screening intentions than respondents who received the standard information only. Controlling for the CRC screening beliefs reduced the effect of group on intention to non-significance.

Conclusions

An additional narrative leaflet had a positive impact on beliefs about CRC screening which led to stronger screening intentions.

Informing the design of a national screening and treatment programme for chronic viral hepatitis in primary care: qualitative study of at-risk immigrant communities and healthcare professionals

Background

Effective strategies are needed to provide screening and treatment for hepatitis B and C to immigrant groups in the UK at high risk of chronic infection. This study aimed to build an understanding of the knowledge, beliefs and attitudes towards these conditions and their management in a range of high-risk minority ethnic communities and health professionals, in order to inform the design of a screening and treatment programme in primary care.

Methods

Qualitative data collection consisted of three sequential phases- (i) semi-structured interviews with key informants (n = 17), (ii) focus groups with people from Chinese, Pakistani, Roma, Somali, and French- and English-speaking African communities (n = 95), and (iii) semi-structured interviews with general practitioners (n = 6). Datasets from each phase were analysed using the Framework method.

Results

Key informants and general practitioners perceived that there was limited knowledge and understanding about hepatitis B and C within high-risk immigrant communities, and that chronic viral hepatitis did not typically feature in community discourses about serious illness. Many focus group participants were confused about the differences between types of viral hepatitis, held misconceptions regarding transmission, and were unaware of the asymptomatic nature of chronic infection. Most welcomed the idea of a screening programme, but key informants and focus group participants also identified numerous practical barriers to engagement with primary care-based screening and treatment; including language and communication difficulties, limited time (due to long working hours), and (for some) low levels of trust and confidence in general practice-based care. General practitioners expressed concerns about the workload implications and sustainability of screening and treating immigrant patients for chronic viral hepatitis in primary care.

Conclusions

Strategies to reduce the burden of chronic viral hepatitis in immigrant communities will need to consider how levels of understanding about hepatitis B and C within these communities, and barriers to accessing healthcare, may affect capacity to engage with screening and treatment. Services may need to work with community groups and language support services to provide information and wider encouragement for screening. Primary care services will need ongoing consultation regarding their support needs to deliver hepatitis screening and treatment programmes.

Attitudes towards colorectal cancer (CRC) and CRC screening tests among elderly Malay patients

BACKGROUND

Colorectal cancer (CRC) is the third most common malignancy in Malaysia, where data are limited regarding knowledge and barriers in regard to CRC and screening tests. The aim of the study was to assess these parameters among Malaysians.

MATERIALS AND METHODS

The questionnaires were distributed in the Umra Private Hospital in Selangor. The questionnaire had four parts and covered social-demographic questions, respondent knowledge about CRC and colorectal tests, attitude towards CRC and respondentaction regarding CRC. More than half of Malay participants (total n=187) were female (57.2%) and 36.9% of them were working as professionals.

RESULTS

The majority of the participants (93.6%) never had a CRC screening test. The study found that only 10.2% of the study participants did not consider that their chances of getting CRC were high. A high percentage of the participants (43.3%) believed that they would have good chance of survival if the cancer would be found early. About one third of the respondents did not want to do screening because of fear of cancer, and concerns of embarrassment during the procedure adversely affected attitude to CRC screening as well. Age, gender, income, family history of CRC, vegetable intake and physical activity were found to be significant determinants of knowledge on CRC.

CONCLUSIONS

The major barriers identified towards CRC screening identified in our study were fear of pain and embarrassment. The findings have implications for understanding of similarities and differences in attitude to CRC amongst elderly patients in other cultural/ geographic regions.

Public awareness of colorectal cancer screening: knowledge, attitudes, and interventions for increasing screening uptake

Colorectal cancer ranks as one of the most incidental and death malignancies worldwide. Colorectal cancer screening has proven its benefit in terms of incidence and mortality reduction in randomized controlled trials. In fact, it has been recommended by medical organizations either in average-risk or family-risk populations. Success of a screening campaign highly depends on how compliant the target population is. Several factors influence colorectal cancer screening uptake including sociodemographics, provider and healthcare system factors, and psychosocial factors. Awareness of the target population of colorectal cancer and screening is crucial in order to increase screening participation rates. Knowledge about this disease and its prevention has been used across studies as a measurement of public awareness. Some studies found a positive relationship between knowledge about colorectal cancer, risk perception, and attitudes (perceived benefits and barriers against screening) and willingness to participate in a colorectal cancer screening campaign. The mentioned factors are modifiable and therefore susceptible of intervention. In fact, interventional studies focused on average-risk population have tried to increase colorectal cancer screening uptake by improving public knowledge and modifying attitudes. In the present paper, we reviewed the factors impacting adherence to colorectal cancer screening and interventions targeting participants for increasing screening uptake.

Attitudes towards cytology and human papillomavirus self-sample collection for cervical screening among Hindu women in London, UK: a mixed methods study

Objectives

To explore the attitudes, views and understanding of women attending a Hindu temple in London, UK towards cervical screening, human papillomavirus (HPV) testing and two HPV self-sample collection devices: the Dacron swab and Evalyn^® brush.

Methods

A mixed methods design comprising a survey and four focus groups was adopted. Focus group discussions were recorded and transcribed verbatim and explored using thematic framework analysis.

Results

A total of 185 Hindu women completed surveys and 23 attended focus groups. Of the respondents 75% aged 25–64 years reported having cervical screening within the last 5 years; 85% had attended college or university. Familiar barriers to attendance for screening were identified: fear of pain and the test result, embarrassment, screener's attitude, inconvenient appointment times and difficulty with child care. Additional barriers cited included age and country of birth, with older and Indian-born women thought to be less likely to attend for screening. Self-collected sampling had a mixed reception. Women were not confident that their sample would be as good as a clinician sample and expressed concern about the impact that a positive HPV result might have on their relationships.

Conclusions

Screening attendance in this highly educated group of Hindu women was slightly lower than in the general population (75% of women aged 25–64 years had been screened in the last 5 years compared with 79% in England as a whole). Familiar barriers to screening were identified. Women felt able to collect their own sample for HPV testing with a Dacron swab but lacked confidence that it would be as good as that obtained by a clinician.

Key genetic considerations in the management of suspected hereditary colorectal cancer

SUMMARY Hereditary bowel cancer syndromes account for up to 5% of colorectal cancer (CRC) incidence. Presentation of CRC under the age of 50 years should alert clinicians to a possible underlying genetic predisposition. This article focuses on Lynch syndrome (hereditary nonpolyposis CRC). Regular bowel screening is effective in reducing the risk of CRC and improving overall survival in Lynch syndrome families. The issues surrounding the clinical diagnostic criteria and the shortcomings of the referral process are described, and it is questioned whether a universal strategy for diagnosis should be employed. This article summarizes the evidence for the benefit of bowel screening and suggests practical steps to help ensure compliance with screening recommendations. Finally, it is discussed how collaboration between geneticists, gastroenterologists and surgeons can inform surgical decision-making for the benefit of the patient.

Screening for colorectal cancer: how can we maximize uptake?

SUMMARY Screening for colorectal cancer is being introduced in a number of countries, yet uptake remains low. The rationalistic model of screening participation explains low uptake in terms of deficient knowledge and high cost. There is evidence to support this view and remedial actions produce anticipated effects up to a point. However, differential uptake among specific groups suggests that the individual decision to participate in screening is idiosyncratic, and understanding decisions requires interpretation in terms of message framing, reference points, the use of simplifying heuristics and affective or emotional reaction. As these aspects of decisions originate from fundamental personal characteristics, they may be difficult to combat. When decision determinants, such as fear and herding, are manipulated, consequences for uptake can be contradictory.

Colorectal cancer screening knowledge, attitudes and behavioural intention among Indigenous Western Australians

Background

Indigenous Australians are significantly less likely to participate in colorectal cancer (CRC) screening compared to non-Indigenous people. This study aimed to identify important factors influencing the decision to undertake screening using Faecal Occult Blood Testing (FOBT) among Indigenous Australians. Very little evidence exists to guide interventions and programmatic approaches for facilitating screening uptake in this population in order to reduce the disparity in colorectal cancer outcomes.

Methods

Interviewer-administered surveys were carried out with a convenience sample (n = 93) of Indigenous Western Australians between November 2009-March 2010 to assess knowledge, awareness, attitudes and behavioural intent in regard to CRC and CRC screening.

Results

Awareness and knowledge of CRC and screening were low, although both were significantly associated with exposure to media advertising (p = 0.008; p < 0.0001). Nearly two-thirds (63%; 58/92) of respondents reported intending to participate in screening, while a greater proportion (84%; 77/92) said they would participate on a doctor’s recommendation. Multivariate analysis with logistic regression demonstrated that independent predictors of screening intention were, greater perceived self-efficacy (OR = 19.8, 95% CI = 5.5-71.8), a history of cancer screening participation (OR = 6.8, 95% CI = 2.0-23.3) and being aged 45 years or more (OR = 4.5, 95% CI = 1.2-16.5). A higher CRC knowledge score (medium vs. low: OR = 9.9, 95% CI = 2.4-41.3; high vs. low: 13.6, 95% CI = 3.4-54.0) and being married or in a de-facto relationship (OR = 6.9, 95% CI = 2.1-22.5) were also identified as predictors of intention to screen with FOBT.

Conclusions

Improving CRC related knowledge and confidence to carry out the FOBT self-screening test through education and greater promotion of screening has the potential to enhance Indigenous participation in CRC screening. These findings should guide the development of interventions to encourage screening uptake and reduce bowel cancer related deaths among Indigenous Australians.

Awareness of cancer risk factors among ethnic minority groups in England

OBJECTIVE

To explore awareness of cancer risk factors in ethnic minority men and women living in England.

STUDY DESIGN

Cross-sectional survey.

METHODS

Men and women were recruited from the six largest ethnic minority groups in the UK proportional to the population distribution: Indian (n = 467); Pakistani (n = 333); Bangladeshi (n = 126); Caribbean (n = 252); African (n = 216); and Chinese (n = 106). Participants responded to an open-ended question about cancer risk factors. Analyses were adjusted for age, gender, socio-economic class and language.

RESULTS

The most commonly cited cancer risk factors were smoking (55%), diet (20%), genetics (20%), drinking alcohol (19%) and lifestyle (17%). On average, participants who were able to name cancer risk factors (91% of respondents) cited 2.13 factors. There were some differences between broad ethnic groups (Asian, Black and Chinese), but fewer differences within them (e.g. between Indian, Pakistani and Bangladeshi, or African and Caribbean).

CONCLUSIONS

Awareness of risk factors (particularly diet and exercise) was lower in this sample than in previous population representative samples in the UK. Interventions aimed at raising awareness of cancer risk factors are likely to be beneficial across the whole ethnic minority population. Any ethnically targeted interventions should consider risk factor awareness levels as well as cancer risk.

Consistency in attitudes across cancer screenings in medically underserved minority populations

While a wide range of behavioral and psychosocial literature explores attitudes and beliefs towards cancer screenings, fewer studies examine attitudes across cancer screening types. We draw on quantitative and qualitative findings from a 4-year prospective study based at a community health center serving diverse, low-income patients. Methods included self-report surveys (n = 297), medical chart abstraction, and several qualitative methods with a subsample of participants. Participants included white, African-American, Vietnamese, and Latino patients who were diagnosed with diabetes, hypertension, or both. Patients' attitudes (both positive and negative) towards cancer screening types were remarkably consistent across cancer screening types. These effects were stronger among men than women. Never having had a cancer screening was generally associated with more unfavorable attitudes towards all screenings. Qualitative interviews indicate the importance of information circulated through social networks in shaping attitudes towards cancer screenings.

CONDENSED ABSTRACT

In a multi-method study of attitudes towards cancer screening among medically underserved patients in a primary care setting, we found that attitudes (both positive and negative) were remarkably consistent across cancer screening types.

Gender and ethnic differences in colorectal cancer screening embarrassment and physician gender preferences

PURPOSE/OBJECTIVES

To examine colorectal cancer (CRC) screening embarrassment among men and women from three ethnic groups and the associated physician gender preference by patient gender and ethnicity.

DESIGN

Cross-sectional, purposive sampling.

SETTING

Urban community in Brooklyn, NY.

SAMPLE

A purpose-derived, convenience sample of 245 European American, African American, and immigrant Jamaican men and women (aged 45-70 years) living in Brooklyn, NY.

METHODS

Participants provided demographics and completed a comprehensive measure of CRC screening embarrassment.

MAIN RESEARCH VARIABLES

Participant gender and ethnicity, physician gender, and CRC screening embarrassment regarding feces or the rectum and unwanted physical intimacy.

FINDINGS

As predicted, men and women both reported reduced fecal and rectal embarrassment and intimacy concern regarding same-gender physicians. As expected, Jamaicans reported greater embarrassment regarding feces or the rectum compared to European Americans and African Americans; however, in contrast to expectations, women reported less embarrassment than men. Interactions indicated that rectal and fecal embarrassment was particularly high among Jamaican men.

CONCLUSIONS

Men and women have a preference for same-gender physicians, and embarrassment regarding feces and the rectum shows the most consistent ethnic and gender variation.

IMPLICATIONS FOR NURSING

Discussing embarrassment and its causes, as well as providing an opportunity to choose a same-gender physician, may be promising strategies to reduce or manage embarrassment and increase CRC screening attendance.

Colorectal cancer screening practise is influenced by ethnicity of medical practitioner and patient

BACKGROUND AND AIM

Colorectal cancer (CRC) screening improves survival and requires appropriate recommendation by general practitioners (GPs). Screening practises may be influenced by barriers related to ethnicity and training.

METHODS

A mail survey assessed GPs' practises and the barriers towards CRC screening. The association of screening practises and demography, including GP ethnicity, medical training and practise characteristics, were evaluated.

RESULTS

Of 212 GPs (median age 54 years, 73% men, 27% Caucasian, 38% foreign graduates), 87% agreed that fecal occult blood test (FOBT) screening improved survival in the average-risk patient. Considerable variations existed in the starting age (40-49 years: 31%; 50 years: 65%) and frequency (1-2 years: 77%; 3-5 years: 22%) of screening. FOBT was used for indications other than screening: anemia (59%), altered bowel habits (54%), abdominal pain (24%), and rectal bleeding (23%), and these were significantly more frequent in Asian GPs independent of medical training. GPs were less likely to recommend screening to immigrants, and most reported that immigrants were less likely to participate. More Asian and Middle Eastern GPs reported a major barrier with FOBT inaccuracy compared with Caucasian GPs (22% vs 9%, P = 0.03; and 27% vs 9%, P = 0.03, respectively).

CONCLUSIONS

Considerable differences existed in GPs' CRC screening practises. Indications for use of FOBT and the subsequent investigation of a positive FOBT also varied according to GPs' ethnicity, independent of medical training. Patient's ethnicity and associated language and cultural barriers may affect screening uptake, which may negatively affect the health of immigrants. Resources and culture-specific interventions are recommended to improve overall screening participation.

Factors influencing colorectal cancer screening participation

Colorectal cancer (CRC) is a major health problem worldwide. Although population-based CRC screening is strongly recommended in average-risk population, compliance rates are still far from the desirable rates. High levels of screening uptake are necessary for the success of any screening program. Therefore, the investigation of factors influencing participation is crucial prior to design and launches a population-based organized screening campaign. Several studies have identified screening behaviour factors related to potential participants, providers, or health care system. These influencing factors can also be classified in non-modifiable (i.e., demographic factors, education, health insurance, or income) and modifiable factors (i.e., knowledge about CRC and screening, patient and provider attitudes or structural barriers for screening). Modifiable determinants are of great interest as they are plausible targets for interventions. Interventions at different levels (patient, providers or health care system) have been tested across the studies with different results. This paper analyzes factors related to CRC screening behaviour and potential interventions designed to improve screening uptake.

The many faeces of colorectal cancer screening embarrassment: preliminary psychometric development and links to screening outcome

OBJECTIVES

Although embarrassment may be among the most easily modified discrete emotional barriers to patients seeking health care or testing, work in the area of colorectal cancer (CRC) has been restricted by the absence of suitable instrumentation. The current report describes the development and validation of a self-report instrument assessing two specific aspects of CRC screening embarrassment and their links to screening outcomes.

DESIGN

Convenience sampling was used to recruit 245 European American, African-American, and immigrant Caribbean community-dwelling men and women (aged 45-75 years) living in Brooklyn, New York.

METHODS

Participants completed the measure of CRC screening embarrassment, an array of convergent and divergent validity measures including dispositional embarrassment, general medical embarrassment, neuroticism, trait emotion, social desirability, previous treatment avoidance because of embarrassment, relevant health characteristics, and a brief CRC screening history.

RESULTS

As expected, CRC screening embarrassment was not unidimensional and had two reliable and distinct components, one concentrated on faecal/rectal embarrassment and the other on embarrassment arising from unwanted intimacy during examinations. In addition to demonstrating patterns of convergent and divergent validity consistent with their separation, multivariate analyses indicated that faecal/rectal embarrassment (but not intimacy concerns) predicted CRC screening frequency.

CONCLUSIONS

The current report extends current understanding by identifying the specific sources of embarrassment that may contribute to patients' avoidance of CRC screening. Directions for future study and implications for clinical practice and interventions are discussed.

Colorectal cancer among Arab-Israeli women--possible reasons for increased incidence and mortality

BACKGROUND

Colorectal cancer (CRC) screening is effective in reducing its incidence by discovering precancerous polyps and detecting early cancer. Evidence indicates lower participation in screening programs among minority ethnic groups. In addition, the Israel Cancer Registry published an increase in the incidence of CRC among Israeli-Arab women. It is important to attempt to understand attitudes toward screening among Israeli-Arab women, assuming it has to do to lack of knowledge and compliance.

METHODS

During the study period, a female team gave lectures in Arabic regarding CRC to women in 16 Arab villages. Prior to the lecture, the participants were asked to complete a questionnaire, obtaining information regarding CRC knowledge and screening. Following the lecture, FOBT kits were distributed. Two weeks later, a telephone survey was performed, regarding whether the FOBT was performed, the result of the test, and, if FOBT was not performed, the reasons for not completing the test.

RESULTS

FOBT was performed by 17.8% prior to the lecture; 61% performed the FOBT following our lecture. Reasons cited for avoiding FOBT: 37% was "afraid of a positive result," 32% avoided performing the test as they were concerned they would be further examined by a male physician; 47.8% concluded that Arab women lack knowledge regarding screening interventions; 23.9% neglect themselves from a health point of view; 11.6% advised that Arab women have no free time to perform tests.

CONCLUSIONS

Israeli-Arab women may be less knowledgeable concerning CRC. Educational efforts must be made to increase awareness and promote benefits of CRC screening, by targeting ethnic minorities and women in Israel.

The 'straight to test' initiative reduces both diagnostic and treatment waiting times for colorectal cancer: outcomes after 2 years

AIM

This study aimed to determine whether a 'straight to test'(STT) strategy for 2-week wait (2 wk) referrals for suspected colorectal cancer (CRC) reduced the time to diagnosis and treatment for patients with CRC.

METHOD

Consecutive 2-week referrals for suspected CRC over a period of 2 years from February 2007 were analysed. The times to the first diagnostic test and treatment and the cancers identified were analysed for those going to STT or the outpatient clinic.

RESULTS

Of 662 patients having a 2 wk referral, 519 (78.4%) were suitable for the hospital colorectal telephone triage service, 121 (18.3%) patients went to STT and 502 (75.8%) were seen in the clinic. Of these 401 (79.8%) underwent diagnostic tests and 25 (6.2%) had CRC and in 12 (2.9%) patients other cancers were detected. In the STT group, 7 (5.8%) patients were diagnosed with CRC. The median time to first diagnostic test was 12 days (IQR 9-13) in the STT pathway, compared with 23 days (17-31) in those seen in the clinic (P < 0.0001). The median time to first treatment was 40 (32-48) days for those via STT, compared to 46 (28-55) days for those seen in the clinic (P = 0.004). A total of 162 CRC were diagnosed during the study period of whom 34 (20.9%) were 2 wk referrals (5.1% of all suspected CRC 2 wk referrals), and 14 (2.1%) other cancers were detected via this pathway.

CONCLUSION

STT speeds up the patient pathway by reducing the time to diagnosis and treatment for patients with CRC.

Promoting cancer screening among Ontario Chinese women

OBJECTIVES

Cancer screening participation is typically low among newcomers to Canada. Consequently, mortality and morbidity rates are higher in ethno/cultural populations. There are inherent challenges in reaching these population groups to increase awareness and participation in cancer screening. Many reports have cited the need for culturally appropriate materials and multi-pronged strategies for effective outreach in the Chinese community. This paper outlines the consultation/development process and evaluation strategy for promoting cancer screening among Chinese women with limited English language skills.

PARTICIPANTS

As Chinese is the third most commonly spoken language in Canada, this community education project focused on health promoters providing services to Chinese women 50 years and older.

SETTING

Ontario communities.

INTERVENTION

Partners and stakeholders were consulted and engaged to define the best approach to develop and distribute culturally sensitive public education resources to assist communities in realizing greater awareness of and participation in cancer screening.

OUTCOMES

Customized resource kits were developed and distributed to the target population over the course of two phases of this project. An evaluation strategy was designed and implemented to assess the impact of the project.

CONCLUSION

The process to develop culturally sensitive and evidence-based materials for Chinese is detailed in this article. This multi-year project designed and distributed customized resource kits, through consultation with partners and stakeholders. Project outcomes will be further assessed one year after distribution of the kits. This project template may be useful for adaptation and use in other ethnocultural groups within and outside Ontario.

Exploring disparities and variability in perceptions and self-reported colorectal cancer screening among three ethnic subgroups of U. S. Blacks

PURPOSE/OBJECTIVES

To explore perceptions of colorectal cancer (CRC) and self-reported CRC screening behaviors among ethnic subgroups of U. S. blacks.

DESIGN

Descriptive, cross-sectional, exploratory, developmental pilot.

SETTING

Medically underserved areas in Hillsborough County, FL.

SAMPLE

62 men and women aged 50 years or older. Ethnic subgroup distribution included 22 African American, 20 English-speaking Caribbean-born, and 20 Haitian-born respondents.

METHODS

Community-based participatory research methods were used to conduct face-to-face individual interviews in the community.

MAIN RESEARCH VARIABLES

Ethnic subgroup, health access, perceptions of CRC (e.g., awareness of screening tests, perceived risk, perceived barriers to screening), healthcare provider recommendation, and self-reported CRC screening.

FINDINGS

Awareness of CRC screening tests, risk perception, healthcare provider recommendation, and self-reported use of screening were low across all subgroups. However, only 55% of Haitian-born participants had heard about the fecal occult blood test compared to 84% for English-speaking Caribbean-born participants and 91% for African Americans. Similarly, only 15% of Haitian-born respondents had had a colonoscopy compared to 50% for the English-speaking Caribbean and African American subgroups.

CONCLUSIONS

This exploratory, developmental pilot study identified lack of awareness, low risk perception, and distinct barriers to screening. The findings support the need for a larger community-based study to elucidate and address disparities among subgroups.

IMPLICATIONS FOR NURSING

Nurses play a major role in reducing cancer health disparities through research, education, and quality care. Recognition of the cultural diversity of the U. S. black population can help nurses address health disparities and contribute to the health of the community.

How equitable are colorectal cancer screening programs which include FOBTs? A review of qualitative and quantitative studies

OBJECTIVE

To review published literature on the equity of participation in colorectal cancer screening amongst different population subgroups, in addition to identifying factors identified as barriers and facilitators to equitable screening. Studies were included in the review if they included FOBT as at least one of the screening tests.

METHOD

Relevant published articles were identified through systematic electronic searches of selected databases and the examination of the bibliographies of retrieved articles. Studies of the association with colorectal cancer screening test participation, barriers to equitable participation in screening, and studies examining interventional actions to facilitate screening test participation were included. Data extraction and analysis was undertaken using an approach to the synthesis of qualitative and quantitative studies called Realist Review.

RESULTS

Sixty-three articles were identified that met the inclusion criteria. SES status, ethnicity, age and gender have been found as predictors of colorectal cancer screening test participation. This review also found that the potential for equitable cancer screening test participation may be hindered by access barriers which vary amongst population sub-groups.

CONCLUSION

This review provides evidence of horizontal inequity in colorectal cancer screening test participation, but limited understanding of the mechanism by which it is sustained, and few evidence-based solutions.

Perceived barriers to flexible sigmoidoscopy screening for colorectal cancer among UK ethnic minority groups: a qualitative study

OBJECTIVES

Evidence from existing UK screening programmes indicates disparities in uptake rates between UK ethnic minorities and the white majority population. The aim of this study was to explore barriers to the uptake of flexible sigmoidoscopy (FS) screening among UK ethnic minority populations. Specifically, beliefs about bowel cancer, perceived barriers to the test and ideas about ways to increase uptake were investigated.

METHODS

Nine focus groups were conducted with a total of 53 participants from African-Caribbean, Gujarati Indian, Pakistani and white British communities. The topic guide was based on the Health Belief Model. Discussions were subject to framework analysis.

RESULTS

Most participants expressed limited awareness of bowel cancer and cited this as a barrier to screening attendance. Anxiety regarding the invasiveness of the test, the bowel preparation and fear of a cancer diagnosis were common barriers across all ethnic groups. Language difficulties, failure to meet religious sensitivities and the expression of culturally influenced health beliefs were all discussed as specific barriers to uptake. Ethnically tailored health promotion and general practitioner involvement were recommended as ways of overcoming such barriers.

CONCLUSIONS

The study was the first attempt to qualitatively explore barriers to FS bowel cancer screening in UK ethnic minorities. Most barriers were shared by all ethnic groups but health educators should supplement approaches designed for the majority to incorporate the specific needs of individual minority groups to ensure equitable access.

Uptake of colorectal cancer screening: system, provider and individual factors and strategies to improve participation

Colorectal cancer (CRC) accounts for 9% of all new cancer cases worldwide and affects over 1 million people each year. Screening can reduce the mortality associated with the disease, yet participation rates are suboptimal. Compliers with CRC screening are less deprived; they have higher education than noncompliers and tend to be male, white and married. Likely reasons for nonparticipation encompass several 'modifiable' factors that could be targeted in interventions aimed at increasing participation rates. Successful intervention strategies include organizational changes, such as increasing access to fecal occult blood test (FOBT) kits, providing reminders to healthcare providers or users about screening opportunities, and educational strategies to improve awareness and attitudes towards CRC screening. Multifactor interventions that target more than one level of the screening process are likely to have larger effects. The biggest challenge for future research will be to reduce inequalities related to socio-economic position and ethnicity in the uptake of screening.

Factors affecting attitudes toward colorectal cancer screening in the primary care population

Background:

Colorectal cancer (CRC) is a major cause of death in the United Kingdom. Regular screening could significantly reduce CRC-related morbidity and mortality. However, screening programmes in the United Kingdom have to date seen uptake rates of less than 60%. Attitudes towards screening are the primary factors determining patient uptake.

Methods:

A questionnaire was sent to people aged 50–69 years who were registered with general practices in the West Midlands. A total of 11 355 people (53%) completed the questionnaire. Multivariable logistic regression analyses were performed to identify those factors (gender, age, ethnicity, deprivation, number of symptoms, and their duration) that most strongly contributed to negative/positive attitudes in the primary care population.

Results:

Fourteen percent of respondents had a negative attitude towards screening. Men, older people, and those with Indian ethnic backgrounds were more likely to have negative attitudes toward screening, whereas people with Black-Caribbean ethnic background, people with multiple symptoms and those reporting abdominal pain, bleeding, and tiredness were more likely to have a positive attitude.

Conclusion:

Culturally relevant screening strategies should aim to increase knowledge of the symptoms and signs related to bowel cancer among South Asian ethnic groups in the United Kingdom. It is also important to find ways to increase the acceptability of screening among asymptomatic patients.

Ethnic differences in participation in flexible sigmoidoscopy screening in the UK

OBJECTIVES

The aim of the study was to examine ethnic differences in participation in colorectal cancer screening by flexible sigmoidoscopy (FS). It assessed both intentions to be screened and actual screening uptake, and considered whether demographic, health and psychosocial factors mediated the ethnic differences. The setting of this study follows a subset of participants from the UK FS Trial.

METHODS

A postal questionnaire assessed ethnicity, demographic characteristics, health, attitudes to screening and FS screening intentions. Data on screening intentions were available for 17,333 adults aged 55-64 years (Sample 1). Screening uptake was recorded in a subsample of 4303 respondents who were subsequently randomized to receive an invitation to screening (Sample 2).

RESULTS

Screening intentions in Sample 1 were equally high across all the ethnic groups (>80% [13,724/17,042] reported they were interested). In contrast, attendance (Sample 2) was considerably lower among Asians (54% [43/79]) compared with White (69% [2843/4123]) or Black (80% [33/41]) respondents. Multivariate analysis showed that potential explanatory factors, including socioeconomic deprivation, poor health and fearful and fatalistic attitudes did not account for the lower screening attendance among Asians.

CONCLUSION

Further research is required to identify explanations for the gap between intentions and behaviour in UK Asians if any future FS screening programme is to be introduced equitably.
