A health systems approach to identifying barriers to breast cancer screening programmes. Methodology and application in six European countries

Barriers of organized cervical cancer screening in Albania and Montenegro

BACKGROUND

Organized cervical screening is vital for preventing cervical cancer. However, many existing screening programs fail to achieve their full potential, as demonstrated by core performance indicators. There are barriers that hinder the implementation and reduce effectiveness of the programs. This article explores barriers of cervical cancer screening in two Southeastern European countries, Albania and Montenegro, aiming to inform targeted strategies to improve healthcare equity and outcomes for women.

METHODS

The barrier assessment followed the EU-TOPIA framework, designed to identify barriers to effective breast-, cervical-, or colon cancer screening. This approach relies on an iterative process performed by country representatives responsible for screening and researchers with expertise in screening program planning and evaluation. It includes three steps: comprehensive description of screening activities; identification of key barriers via a previously published tool; and comprehensive assessment of the identified key barriers.

RESULTS

The barrier assessment revealed shared challenges in cervical cancer screening in Albania and Montenegro. Both countries face difficulties in their invitation systems, limited outreach activities, and low participation rates. Fully integrated data systems at national level are absent, hindering program monitoring and data sharing. Financial constraints and resource limitations negatively affect program sustainability and quality, reducing public awareness and accessibility. Additionally, neither country has comprehensive up-to-date long-term strategies to support prevention and early detection efforts.

CONCLUSIONS

Our study underscores the importance of addressing organizational barriers in cervical cancer screening to improve program effectiveness and accessibility. Aligning screening practices with EU and WHO standards is crucial for Albania and Montenegro as prospective EU members. Lessons from international best practices, such as integrating IT systems, employing multi-channel outreach strategies, and adopting legally supported long-term policies, offer actionable pathways for improvement. Policymakers should prioritize sustainable funding, centralized systems, and innovative approaches to overcome structural challenges.

The potential of a population register for addressing health inequities: an observational study using data linkage to improve breast cancer screening enrolment and participation in Indigenous Māori women in Aotearoa New Zealand

BACKGROUND

Breast cancer screening in Aotearoa New Zealand (NZ) still has persistent inequitable coverage by ethnicity, especially for Indigenous Māori women. This project aimed to undertake systematic data linkage to identify and invite eligible Māori women to participate in breast screening.

METHODS

This is a cross-sectional observational study conducted in Northern New Zealand between 1/01/2020 and 30/06/2021. The BreastScreen Aotearoa (BSA) register was linked with the primary care data to identify and invite eligible Māori women (aged 45-69 years) to breast screening, who were not currently enrolled in BSA, and who were enrolled in BSA but had not been screened or overdue for breast screening. Invitations were sent through invitation letters, text messages and phone calls. Enrolment to BSA and screening participation at 15 and 18 months from the project's start date were reported.

RESULTS

Through the data linkage, 2295 women who were not enrolled in BSA were identified eligible for breast screening. Approximately half (n = 1086) of the women were contactable within 5 contact attempts. Of these contactable, 345 (32%) women were enrolled in BSA, 421 (39%) were screened at 15 months, increasing to 441 (41%) at 18 months from the project start. Among women who were previously enrolled but never screened or overdue for screening, 1470 women were eligible. Their contact details were updated through the data linkage, which facilitated BSA to contact them successfully for breast screening. Consequently, 305 (21%) of these eligible were screened at 15 months, and increased to 332 (23%) at 18 months.

CONCLUSIONS

The data linkage approach has evidenced the benefit of a population register to facilitate equitable access to breast screening services. Further work is needed on choices of combined approaches for optimising screening uptake equitably.

Development and pilot testing of INTERVENER, a web-based tool to match barriers to the cancer continuum organization to evidence-based interventions

BACKGROUND

Barriers to the cancer continuum organization and interventions to approach them have been identified; however, there is a lack of a tool matching them. Our aim was to develop a web-based tool to identify the main barriers to the process of the cancer continuum organization, and propose matched evidence-based interventions (EBI) to overcome them.

METHODS

A questionnaire on barriers at six steps of the process of the cancer continuum organization was answered by collaborators. Each question included several options of barriers to be ranked. Barriers were organized in a framework based on the Tanahashi conceptual model, and were categorized in these dimensions: availability of services, accessibility, affordability, acceptability, user-provider interaction, governance, protocols and guidelines, information system, and quality assurance. Systematic searches were conducted on interventions for breast, cervical and colorectal cancer. Interventions were matched with the barriers they helped to overcome, and were classified in one of these groups for each barrier and cancer site: EBI as a single strategy, EBI within a multicomponent strategy, limited-evidence interventions, and macro level approaches. Barriers and interventions were matched on a web-based tool named INTERVENER, that allows the selection of up to 3 barriers for each step. It displays the visual representation of the selected barriers, the size of each dimension being proportional with the importance of that dimension as a barrier. Experts on different aspects of screening and cancer sites provided feedback on the tool. Collaborators from 41 countries worldwide tested it.

RESULTS

The tool matched 81 barriers with over 60 interventions. Collaborators reported the webpage to be organized logically (N = 17, 94%) and clearly formatted (N = 15, 83%). The tool was found useful for conducting a situational analysis of the barriers to cancer screening (N = 16, 89%), facilitating discussion with stakeholders on prioritization of interventions (N = 15, 83%), and planning their implementation (N = 15, 83%).

CONCLUSION

This tool supports countries in conducting a systematic assessment of barriers, including their prioritization, and identifying EBI to overcome them, ultimately facilitating reduction of health inequalities. This tool can support governments, policymakers, managers, and healthcare providers to make better informed decisions to improve their cancer screening programmes.

Mind the implementation gap: a systems analysis of the NHS Long Term Workforce Plan to increase the number of doctors trained in the UK raises many questions

BACKGROUND

The National Health Service (NHS) in England is facing a workforce crisis. A new Long Term Workforce Plan (LTWP) seeks to address this, setting out ambitious proposals to expand and reform domestic medical education and training in England. However, there are concerns about their feasibility.

SOURCES OF DATA

In September 2023, over 60 individuals representing medical education and training in the UK participated in an exercise run by UK Medical Schools Council by using systems theory to identify risks.

AREAS OF AGREEMENT

The UK does need more 'home grown' doctors, but the LTWP has important gaps, including lack of attention to postgraduate training, absence of reference to the need for more educators and capital investment and risk of inadequate clinical placement capacity, particularly in primary care settings.

AREAS OF CONTROVERSY

There are unresolved differences in the understanding of a proposed medical apprenticeship model and no scheme has, as yet, been approved by the General Medical Council. Participants were unable to determine who the beneficiaries of this scheme will be (apart from the apprentices themselves).

GROWING POINTS

While the LTWP represents a welcome, although overdue, commitment to address the NHS workforce crisis, we identified significant gaps that must be resolved.

AREAS TIMELY FOR DEVELOPING RESEARCH

First, the development of the LTWP provides a case study that adds to literature on policymaking in the UK. Second, while we only examined the expansion of medical training, the method could be applied to other parts of the LTWP. Third, a prospective evaluation of its implementation is necessary.

Overcoming barriers: Modelling the effect of potential future changes of organized breast cancer screening in Italy

OBJECTIVES

Organized breast cancer screening may not achieve its full potential due to organizational and cultural barriers. In Italy, two identified barriers were low attendance in Southern Italy and, in Italy as a whole, underscreening and overscreening in parts of the eligible population. The objective of this study was to identify potential changes to overcome these barriers and to quantify their costs and effects.

METHODS

To assess the impact of potential measures to improve breast cancer screening in Italy, we performed an evaluation of costs and effects for increasing adherence for Southern Italy and harmonizing screening intervals (biennial screening) for the whole of Italy, using an online tool (EU-TOPIA evaluation tool) based on the MIcrosimulation SCreening ANalysis (MISCAN) model.

RESULTS

Increasing adherence in Southern Italy through investing in mobile screening units has an acceptable cost-effectiveness ratio of €9531 per quality-adjusted life year gained. Harmonizing the screening interval by investing in measures to reduce opportunistic screening and simultaneously investing in mobile screening units to reduce underscreening is predicted to gain 1% fewer life-years, while saving 19% of total screening costs compared to the current situation.

CONCLUSIONS

Increasing adherence in Southern Italy and harmonizing the screening interval could result in substantial improvements at acceptable costs, or in the same benefits at lower costs. This example illustrates a systematic approach that can be easily applied to other European countries, as the online tools can be used by stakeholders to quantify effects and costs of a broad range of specific barriers, and ways to overcome them.

Implementing organized colorectal cancer screening programs in Europe-protocol for a systematic review of determinants and strategies

BACKGROUND

With a high mortality of 12.6% of all cancer cases, colorectal cancer (CRC) accounts for substantial burden of disease in Europe. In the past decade, more and more countries have introduced organized colorectal cancer screening programs, making systematic screening available to entire segments of a population, typically based on routine stool tests and/or colonoscopy. While the effectiveness of organized screening in reducing CRC incidence and mortality has been confirmed, studies continuously report persistent program implementation challenges. This systematic review will synthesize the literature on organized CRC screening programs. Its aim is to understand what is currently known about the barriers and facilitators that influence the implementation of these programs and about the implementation strategies used to navigate these determinants.

METHODS

A systematic review of primary studies of any research design will be conducted. CENTRAL, CINAHL, EMBASE, International Clinical Trials Registry Platform, MEDLINE, PsycINFO, and Scopus will be searched. Websites of (non-)government health care organizations and websites of organizations affiliated with authors of included studies will be screened for unpublished evaluation reports. Existing organized CRC screening programs will be contacted with a request to share program-specific grey literature. Two researchers will independently screen each publication in two rounds for eligibility. Included studies will focus on adult populations involved in the implementation of organized CRC screening programs and contain information about implementation determinants/ strategies. Publications will be assessed for their risk of bias. Data extraction will include study aim, design, location, setting, sample, methods, and measures; program characteristics; implementation stage, framework, determinants, strategies, and outcomes; and service and other outcome information. Findings will be synthesized narratively using the three stages of thematic synthesis.

DISCUSSION

With its sole focus on the implementation of organized CRC screening programs, this review will help to fill a central knowledge gap in the literature on colorectal cancer screening. Its findings can inform the decision-making in policy and practice needed to prioritize resources for establishing new and maintaining existing programs in the future.

Breast health awareness campaign and screening pilot in a Kenyan County: Findings and lessons

BACKGROUND AND AIM

Breast cancer is the leading cancer in terms of incidence in Kenya. We conducted a breast cancer awareness and screening pilot to assess feasibility of rolling out a national screening program in Kenya.

METHODS

Conducted in Nyeri County during October-November 2019, the pilot had three phases; awareness creation, screening (clinical breast examination and/or imaging) and final evaluation (post-screening exit interviews and retrospective screening data review). Descriptive statistics on awareness, screening process and outputs were derived.

RESULTS

During the pilot, 1813 CBE, 217 breast ultrasounds and 600 mammograms were performed. Mammography equipment utilization increased from 11% to 83%. Of 49 women with suspicious lesions on mammography, only 22 (44.9%) had been linked to care 4 months after the campaign. Of 532 exit interview respondents; 95% (505/532) were ≥35 years of age; 80% (426/532) had been reached by the awareness campaign. Majority (75% [399/532]) had received information from community health volunteers; 68% through social groups. Majority (79% [420/532]) felt the campaign had changed their behavior on breast health. Although 77% (407/532) had knowledge on self breast examination (SBE); only 13% practiced monthly SBE. More than half (58% [306/532]) had previously undertaken a CBE. Approximately 70% (375/528) were unaware of mammography before the pilot; 86% (459/532) had never previously undertaken a mammogram. Fifty-five percent (293/532) of respondents had screening waiting times of >120 min.

CONCLUSION

Community health workers can create breast cancer screening demand sustainably. Adequate personnel and effective follow-up are crucial before national roll-out of a breast cancer screening program.

Quality assured implementation of the Slovenian breast cancer screening programme

SETTING

The organised, population-based breast cancer screening programme in Slovenia began providing biennial mammography screening for women aged 50-69 in 2008. The programme has taken a comprehensive approach to quality assurance as recommended by the European guidelines for quality assurance in breast cancer screening and diagnosis (4th edition), including centralized assessment, training and supervision, and proactive monitoring of performance indicators. This report describes the progress of implementation and rollout from 2003 through 2019.

METHODS

The screening protocol and key quality assurance procedures initiated during the planning from 2003 and rollout from 2008 of the screening programme, including training of the professional staff, are described. The organisational structure, gradual geographical rollout, and coverage by invitation and examination are presented.

RESULTS

The nationwide programme was up and running in all screening regions by the end of 2017, at which time the nationwide coverage by invitation and examination had reached 70% and 50%, respectively. Nationwide rollout of the population-based programme was complete by the end of 2019. By this time, coverage by invitation and examination had reached 98% and 76%, respectively. The participation rates consistently exceeded 70% from 2014 to 2019.

CONCLUSIONS

The successful implementation of the screening programme can be attributed to an independent central management, external guidance, and strict adherence to quality assurance procedures, all of which contributed to increasing governmental and popular support. The benefits of quality assurance have influenced all aspects of breast care and have provided a successful model for multidisciplinary management of other diseases.

A roadmap for a comprehensive control of cervical cancer in Poland: integration of available solutions into current practice in primary and secondary prevention

In Poland, cervical cancer incidence and mortality still remain considerably higher than in Western European countries or North America. Recent data indicate decreasing trends in women younger than 60 years and stable trends in older women. In this article, we identified obstacles in primary and secondary prevention of cervical cancer in Poland. We analysed local legislation, management structure and organization of cervical cancer prevention in Poland and reviewed solutions available and implemented in other European countries. The main weaknesses include: (i) very low coverage of organized screening; concurrent unregistered opportunistic screening with unknown coverage and high test consumption (ii) suboptimal quality assurance in organized screening and no external quality assurance in opportunistic screening (iii) very low coverage of human papillomavirus vaccination that is not centrally reimbursed (iv) absence of pilot evaluation of (a) interventions that may improve population coverage and (b) performance of new preventive strategies. The proposed solutions are multifaceted and involve: (i) legislative and organizational regulation of cervical cancer screening aimed at comprehensive registration of procedures, data access and quality assurance (ii) pilot testing and implementation of new ways to increase coverage of cervical cancer screening, in particular among older women (iii) pilot evaluation with possible introduction of human papillomavirus-based screening and (iv) inclusion of human papillomavirus vaccination into the reimbursed national immunization program.

The potential of breast cancer screening in Europe

Currently, all European countries offer some form of breast cancer screening. Nevertheless, disparities exist in the status of implementation, attendance and the extent of opportunistic screening. As a result, breast cancer screening has not yet reached its full potential. We examined how many breast cancer deaths could be prevented if all European countries would biennially screen all women aged 50 to 69 for breast cancer. We calculated the number of breast cancer deaths already prevented due to screening as well as the number of breast cancer deaths which could be additionally prevented if the total examination coverage (organised plus opportunistic) would reach 100%. The calculations are based on total examination coverage in women aged 50 to 69, the annual number of breast cancer deaths for women aged 50 to 74 and the maximal possible mortality reduction from breast cancer, assuming similar effectiveness of organised and opportunistic screening. The total examination coverage ranged from 49% (East), 62% (West), 64% (North) to 69% (South). Yearly 21 680 breast cancer deaths have already been prevented due to mammography screening. If all countries would reach 100% examination coverage, 12 434 additional breast cancer deaths could be prevented annually, with the biggest potential in Eastern Europe. With maximum coverage, 23% of their breast cancer deaths could be additionally prevented, while in Western Europe it could be 21%, in Southern Europe 15% and in Northern Europe 9%. Our study illustrates that by further optimising screening coverage, the number of breast cancer deaths in Europe can be lowered substantially.

Optimizing the Quality of Colorectal Cancer Screening Worldwide

Screening, followed by colonoscopic polypectomy (or surgery for malignant lesions), prevents incident colorectal cancer and mortality. However, there are variations in effective application of nearly every aspect of the screening process. Screening is a multistep process, and failure in any single step could result in unnecessary morbidity and mortality. Awareness of variations in operator- and system-dependent performance has led to detailed, comprehensive recommendations in the United States and Europe on how colonoscopy screening should be performed and measured. Likewise, guidance has been provided on quality assurance for nonprimary colonoscopy-based screening programs, including strategies to maximize adherence. Quality improvement is now a validated science, and there is clear evidence that higher quality prevents incident cancer and cancer death. Quality must be addressed at the levels of the system, provider, and individuals, to maximize the benefits of screening for any population. We review the important aspects of measuring and improving the quality of colorectal cancer screening.
