Effectiveness of patient-targeted interventions to increase cancer screening participation in rural areas: A systematic review

Interventions to promote colorectal cancer screening among people with a family history of colorectal cancer: A scoping review

BACKGROUND

The global incidence of colorectal cancer (CRC) is rising, with people having a family history of CRC (PFH-CRC) facing double the risk compared to the average-risk population. Despite this, CRC screening uptake among PFH-CRC remains low. There is a lack of systematic mapping of interventions promoting CRC screening in this high-risk population.

OBJECTIVE

We conducted a scoping review to identify the types of interventions targeting PFH-CRC, their effectiveness in increasing CRC screening uptake, and the elements associated with the outcomes.

METHODS

The Joanna Briggs Institute methodology for scoping review was followed. The search for eligible articles was conducted from the inception of each database until 17 July 2024 in PubMed, EMBASE, CINAHL, Cochrane, PsycINFO and Web of Science with no restrictions on language.

RESULTS

Thirty studies from 1995 to 2023 across 13 countries were included; mostly from high-income countries. There was considerable variability in study design, intervention characteristics, and screening outcomes. Eleven studies used theoretical frameworks in intervention development. Fourteen studies reported statistically significant increases in screening uptake among PFH-CRC, most using complex, multiple-component interventions. Tailored print materials and patient navigation more consistently demonstrated increased screening uptake, while counselling yielded mixed results.

CONCLUSION

Interventions for promoting CRC screening uptake in PFH-CRC commonly incorporate print material, patient navigation and counselling, often combined into complex interventions. Future research should include more implementation studies to translate these interventions into real-world settings. Additionally, there are gaps in research from low- and middle-income countries, highlighting the need for further research in these resource-limited settings.

The global burden of breast cancer in women from 1990 to 2030: assessment and projection based on the global burden of disease study 2019

Background and aim

This study aims to analyze the worldwide prevalence, mortality rates, and disability-adjusted life years (DALYs) attributed to breast cancer in women between 1990 and 2019. Additionally, it seeks to forecast the future trends of these indicators related to the burden of breast cancer in women from 2020 to 2030.

Methods

Data from the Global Burden of Disease Study (GBD) 2019 was analyzed to determine the age-standardized incidence rate (ASIR) and age-standardized death rate (ASDR) of DALYs due to breast cancer in women across 204 countries and territories from 1990 to 2019. Socio-economic development levels of countries and regions were assessed using Socio-demographic Indexes, and trends in the burden of breast cancer in women worldwide from 2020 to 2030 were projected using generalized additive models (GAMs).

Results

The estimated annual percentage change (EAPC) in the ASIR breast cancer in women globally was 0.36 from 1990 to 2019 and is expected to increase to 0.44 from 2020 to 2030. In 2019, the ASIR of breast cancer in women worldwide was 45.86 and is projected to reach 48.09 by 2030. The burden of breast cancer in women generally rises with age, with the highest burden expected in the 45-49 age group from 2020 to 2030. The fastest increase in burden is anticipated in Central sub-Saharan Africa (EAPC in the age-standardized death rate: 1.62, EAPC in the age-standardized DALY rate: 1.52), with the Solomon Islands (EAPC in the ASIR: 7.25) and China (EAPC in the ASIR: 2.83) projected to experience significant increases. Furthermore, a strong positive correlation was found between the ASIR breast cancer in women globally in 1990 and the projected rates for 2030 (r = 0.62).

Conclusion

The anticipated increase in the ASIR of breast cancer in women globally by 2030 highlights the importance of focusing on women aged 45-49 in Central sub-Saharan Africa, Oceania, the Solomon Islands, and China. Initiatives such as breast cancer information registries, raising awareness of risk factors and incidence, and implementing universal screening programs and diagnostic tests are essential in reducing the burden of breast cancer and its associated morbidity and mortality.

Barriers and facilitators of implementing a multicomponent intervention to improve faecal immunochemical test (FIT) colorectal cancer screening in primary care clinics, Alberta

BACKGROUND AND OBJECTIVE

Colorectal cancer (CRC) screening is effective at reducing the incidence and mortality of CRC. To address suboptimal CRC screening rates, a faecal immunochemical test (FIT) multicomponent intervention was piloted in four urban multidisciplinary primary care clinics in Alberta from September 2021 to April 2022. The interventions included in-clinic distribution of FIT kits, along with FIT-related patient education and follow-up. This study explored barriers and facilitators to implementing the intervention in four primary clinics using the Consolidated Framework for Implementation Research (CFIR).

METHODS

In-depth qualitative semistructured key informant interviews, guided by the CFIR, were conducted with 14 participants to understand barriers and facilitators of the FIT intervention implementation. Key informants were physicians, quality improvement facilitators and clinical staff. Interviews were analysed following an inductive-deductive approach. Implementation barriers and facilitators were organised and interpreted using the CFIR to facilitate the identification of strategies to mitigate barriers and leverage facilitators for implementation at the clinic level.

RESULTS

Key implementation facilitators reported by participants were patient perceived needs being met; the clinics' readiness to implement FIT, including staff's motivation, skills, knowledge, and resources to implement; intervention characteristics-evidence-based, adaptable and compatible with existing workflows; regular staff communications; and use of the electronic medical record (EMR) system. Key barriers to implementation were patient's limited awareness of FIT screening for CRC and discomfort with stool sample collection; the impacts of COVID-19 (patients missed appointment, staff coordination and communication were limited due to remote work); and limited clinic capacity (knowledge and skills using EMR system, staff turnover and shortage).

CONCLUSION

Findings from the study facilitate the refinement and adaption of future FIT intervention implementation. Future research will explore implementation barriers and facilitators in rural settings and from patients' perspectives to enhance the spread and scale of the intervention.

A theory-driven, culture-tailored educational intervention for cervical cancer screening among rural Chinese females: A feasibility and pilot study

Objective

This study aimed to evaluate the feasibility and preliminarily estimate the effects of a theory-driven, culture-tailored, community-based educational intervention promoting cervical cancer screening among rural females.

Methods

An experimental study with the two-arm parallel, nonrandomized control trial design was implemented, followed by individual semi-structured interviews. Thirty rural females between 26 and 64 were recruited, with 15 in each group. Both groups were exposed to the usual care about cervical cancer screening promotion from the local clinics, while participants in the intervention group additionally received five educational sessions in 5 weeks. Data were collected at baseline and immediately postintervention.

Results

All participants completed the study, and the retention rate was 100%. Participants in the intervention group had more significant increments in cervical cancer screening-related self-efficacy (P ​< ​0.001), knowledge (P ​< ​0.001), and intention levels (P ​= ​0.003) than those in the control group. Most participants showed acceptance and satisfaction with this educational intervention.

Conclusions

This study revealed that the theory-driven, culture-tailored, community-based educational intervention was feasible among the rural populations to promote cervical cancer screening. A large-scale interventional study with a prolonged follow-up duration is warranted to explore this educational intervention's effectiveness further.

Barriers and facilitators to cancer clinical trial enrollment and participation among rural populations: a scoping review protocol

OBJECTIVE

The objective of this scoping review is to identify barriers and facilitators related to cancer clinical trial enrollment and participation among rural populations.

INTRODUCTION

Advancing the effectiveness of cancer treatment and increasing early detection of cancer relies on enrollment and participation of individuals in cancer clinical trials. Lack of enrollment and participation in trials is a concern, and there is evidence that individuals living in rural areas are unlikely to participate in such trials. Information on barriers to, and facilitators of, enrollment and participation in cancer clinical trials is needed for the development of evidence-based interventions to increase the enrollment and participation of rural populations.

INCLUSION CRITERIA

The review will consider studies on adults aged 18 years or older living in rural areas. Studies that report on barriers and facilitators to enrollment and participation in cancer clinical trials, including both cancer therapeutic and cancer early detection trials, will be included in the review. The review will consider quantitative, qualitative, and text and opinion papers for inclusion.

METHODS

The search strategy will aim to locate published primary studies, reviews, and opinion papers, the latter including those by professional oncology organizations. The databases to be searched include MEDLINE, CINAHL, Embase, Web of Science, and Cochrane Library. Gray literature databases will also be searched. Two independent reviewers will retrieve full-text studies and extract data. The results will be presented in diagrammatic format with a narrative summary.

Educational Interventions to Promote Cervical Cancer Screening among Rural Populations: A Systematic Review

The urban-rural gap in cervical cancer screening uptake is a significant public health consideration. Educational interventions are commonly adopted to promote cervical cancer screening among females in rural areas; however, the characteristics and effectiveness of these educational interventions remain unclear. In this review, we aimed to identify the characteristics of educational interventions used in rural populations and to evaluate the effects of these interventions on cervical cancer screening-related outcomes. Seven English databases were searched in January 2022. Randomized controlled trials (RCTs) and quasi-experimental studies were included. The Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Randomized Controlled Trials and the JBI Critical Appraisal Checklist for Quasi-Experimental Studies were used for quality appraisal. RevMan 5.4 software was used for the meta-analysis. A narrative synthesis was conducted in instances where a meta-analysis was inappropriate. Three RCTs and seven quasi-experimental studies conducted in six countries were included. A social cognitive theory-based framework, the community setting, group sessions, healthcare professional-led approaches, and culture-tailored materials were implemented in the educational interventions for cervical cancer screening. The educational content mainly included basic information on cervical cancer screening, psychological issues, barriers and strategies to overcome them, and locally available resources. Educational interventions increased the knowledge and uptake of cervical cancer screening in the rural population. However, the studies only evaluated the short-term effects of these educational interventions, with the cervical screening behavior only being assessed in one instance for each participant. Educational interventions promote cervical cancer screening among females in rural areas. Theory-driven, community-involved, group-based, and healthcare professional-led approaches should be prioritized in the application of educational interventions in rural populations. Both the short- and long-term, influences of educational interventions on the cervical cancer screening behavior of females in rural areas need to be recognized.

Using a Frontline Staff Intervention to Improve Cervical Cancer Screening in a Large Academic Internal Medicine Clinic

BACKGROUND

Cervical cancer is the third most common malignancy affecting women. Screening with Papanicolaou (Pap) tests effectively identifies precancerous lesions and early-stage cervical cancer. While the nationwide rate of cervical cancer screening (CCS) is 84%, our urban general internal medicine (GIM) clinic population had a CCS rate of 70% in 2016.

OBJECTIVE

To improve our clinic's CCS rate to match or exceed the national average within 18 months by identifying barriers and testing solutions.

DESIGN

A quality improvement project led by a multidisciplinary group of healthcare providers.

PARTICIPANTS

Our GIM clinic includes 16 attending physicians, 116 resident physicians, and 20 medical assistants (MAs) with an insured and underserved patient population.

INTERVENTION

Phase 1 lasted 9 months and implemented CCS patient outreach, patient financial incentives, and clinic staff education. Phase 2 lasted 9 months and involved a workflow change in which MAs identified candidates for CCS during patient check-in. Feedback spanned the entire study period.

MAIN MEASURES

Our primary outcome was the number of Pap tests completed per month during the 2 study phases. Our secondary outcome was the clinic population's CCS rate for all eligible clinic patients.

KEY RESULTS

After interventions, the average number of monthly Pap tests increased from 35 to 56 in phase 1 and to 75 in phase 2. Of 385 patients contacted in phase 1, 283 scheduled a Pap test and 115 (41%) completed it. Compared to baseline, both interventions improved cervical cancer screening (phase 1 relative risk, 1.86; 95% CI, 1.64-2.10; P < 0.001; phase 2 relative risk, 2.70; 95% CI, 2.40-3.02; P < 0.001). Our clinic's CCS rate improved from 70% to 75% after the 18-month intervention.

CONCLUSIONS

The rate of CCS increased by 5% after a systematic 2-phase organizational intervention that empowered MAs to remind, identify, and prepare candidates during check-in for CCS.

Exploring the influence of rural residence on uptake of organized cancer screening - A systematic review of international literature

Lower screening uptake could impact cancer survival in rural areas. This systematic review sought studies comparing rural/urban uptake of colorectal, cervical and breast cancer screening in high income countries. Relevant studies (n = 50) were identified systematically by searching Medline, EMBASE and CINAHL. Narrative synthesis found that screening uptake for all three cancers was generally lower in rural areas. In meta-analysis, colorectal cancer screening uptake (OR 0.66, 95 % CI = 0.50-0.87, I² = 85 %) was significantly lower for rural dwellers than their urban counterparts. The meta-analysis found no relationship between uptake of breast cancer screening and rural versus urban residency (OR 0.93, 95 % CI = 0.80-1.09, I² = 86 %). However, it is important to note the limitation of the significant statistical heterogeneity found which demonstrates the lack of consistency between the few studies eligible for inclusion in the meta-analyses. Cancer screening uptake is apparently lower for rural dwellers which may contribute to poorer survival. National screening programmes should consider geography in planning.

Lung cancer screening implementation: Complexities and priorities

Lung cancer is the number one cause of cancer death worldwide. The benefits of lung cancer screening to reduce mortality and detect early-stage disease are no longer in any doubt based on the results of two landmark trials using LDCT. Lung cancer screening has been implemented in the US and South Korea and is under consideration by other communities. Successful translation of demonstrated research outcomes into the routine clinical setting requires careful implementation and co-ordinated input from multiple stakeholders. Implementation aspects may be specific to different healthcare settings. Important knowledge gaps remain, which must be addressed in order to optimize screening benefits and minimize screening harms. Lung cancer screening differs from all other cancer screening programmes as lung cancer risk is driven by smoking, a highly stigmatized behaviour. Stigma, along with other factors, can impact smokers' engagement with screening, meaning that smokers are generally 'hard to reach'. This review considers critical points along the patient journey. The first steps include selecting a risk threshold at which to screen, successfully engaging the target population and maximizing screening uptake. We review barriers to smoker engagement in lung and other cancer screening programmes. Recruitment strategies used in trials and real-world (clinical) programmes and associated screening uptake are reviewed. To aid cross-study comparisons, we propose a standardized nomenclature for recording and calculating recruitment outcomes. Once participants have engaged with the screening programme, we discuss programme components that are critical to maximize net benefit. A whole-of-programme approach is required including a standardized and multidisciplinary approach to pulmonary nodule management, incorporating probabilistic nodule risk assessment and longitudinal volumetric analysis, to reduce unnecessary downstream investigations and surgery; the integration of smoking cessation; and identification and intervention for other tobacco related diseases, such as coronary artery calcification and chronic obstructive pulmonary disease. National support, integrated with tobacco control programmes, and with appropriate funding, accreditation, data collection, quality assurance and reporting mechanisms will enhance lung cancer screening programme success and reduce the risks associated with opportunistic, ad hoc screening. Finally, implementation research must play a greater role in informing policy change about targeted LDCT screening programmes.

Assessing the Effectiveness of Cancer Screening Interventions Targeting Appalachian Populations: A Systematic Review

PURPOSE

Appalachian residents have higher cancer prevalence and invasive cancer incidence in almost all cancer types relative to non-Appalachian residents. Public health interventions have been carried out to increase preventive cancer screening participation. However, no studies have evaluated the effectiveness of existing interventions targeting cancer screening uptake in this high-risk population. The main objective of this study is to assess the effectiveness of interventions aimed at increasing uptake and/or continuing participation in screened cancers (breast, cervical, colorectal, lung, and prostate) in Appalachia.

METHODS

We conducted a systematic review of electronic databases and gray literature using a combination of MeSH and free-text search terms related to breast, cervical, colorectal, lung, and prostate cancer; mass screening; health promotion; and Appalachia. We identified 3,014 articles of which 15 articles were included. We assessed methodological quality using validated tools and analyzed findings using narrative synthesis.

FINDINGS

Fifteen studies reported uptake and/or continued participation in screening interventions; these focused on cervical (n = 7), colorectal (n = 5), breast (n = 2), and lung (n = 1) cancers in Appalachia. Interventions included diverse components: mass media campaigns, community outreach events, community health workers, interpersonal counseling, and educational materials. We found that multi-strategy interventions had higher screening uptake relative to interventions employing 1 intervention strategy. Studies that targeted noncompliant populations and leveraged existing community-based organization partnerships had a substantial increase in screening participation versus others.

CONCLUSIONS

There is an urgent need for further research and implementation of effective cancer prevention and screening interventions to reduce disparities in cancer morbidity and mortality in Appalachian populations.

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

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