Patterns of up-to-date status for colorectal cancer screening in Alberta: a cross-sectional study using survey data

Evaluating the implementation of a multicomponent intervention to improve faecal immunochemical test-based (FIT) colorectal cancer screening in primary care

Screening has proven effective at reducing the incidence and mortality of colorectal cancer (CRC). The faecal immunochemical test (FIT) is recommended for screening people aged 50-74 years at average risk of CRC in Alberta, Canada. This project implemented a multicomponent intervention in real-world, primary care settings in Alberta to improve the FIT participation rate and evaluated the reach, effectiveness and implementation outcomes.The multicomponent intervention comprised of in-clinic FIT kit distribution, patient education and reminder calls, was implemented in four primary care clinics. Reach was measured as the proportion of patients receiving the intervention. Effectiveness was measured by comparing the proportion of patients completing FIT during preintervention and perintervention periods. Implementation was measured by the perceived acceptability, appropriateness and feasibility of providers in implementing the intervention. Data were collected from electronic medical records and validated survey tools.Four clinics implemented the intervention during an 8-month study period (September 2021 to April 2022); 99% of eligible patients received a FIT kit. The baseline FIT completion rate across participating clinics was 62%, which increased by 13 percentage points to 75% during the intervention period. Of the 75% who completed the FIT, 56% did without a reminder call, whereas 19% did so after receiving one or more reminders. More than 90% of providers perceived the intervention implementation as acceptable, feasible and appropriate.The multicomponent FIT intervention was perceived as acceptable, feasible, and appropriate and improved the FIT screening rates in pilot clinics. An implementation guidance document has been developed and tested to communicate the implementation process for use by other primary care clinics and aid in the spread of the intervention across Alberta. Implementing this intervention in routine practice can help decrease the incidence and mortality of CRC.

Effective strategies for Fecal Immunochemical Tests (FIT) programs to improve colorectal cancer screening uptake among populations with limited access to the healthcare system: a rapid review

BACKGROUND

Colorectal cancer (CRC) is one of the leading causes of cancer death globally. CRC screening can reduce the incidence and mortality of CRC. However, socially disadvantaged groups may disproportionately benefit less from screening programs due to their limited access to healthcare. This poor access to healthcare services is further aggravated by intersecting, cumulative social factors associated with their sociocultural background and living conditions. This rapid review systematically reviewed and synthesized evidence on the effectiveness of Fecal Immunochemical Test (FIT) programs in increasing CRC screening in populations who do not have a regular healthcare provider or who have limited healthcare system access.

METHODS

We used three databases: Ovid MEDLINE, Embase, and EBSCOhost CINAHL. We searched for systematic reviews, meta-analysis, and quantitative and mixed-methods studies focusing on effectiveness of FIT programs (request or receipt of FIT kit, completion rates of FIT screening, and participation rates in follow-up colonoscopy after FIT positive results). For evidence synthesis, deductive and inductive thematic analysis was conducted. The findings were also classified using the Cochrane Methods Equity PROGRESS-PLUS framework. The quality of the included studies was assessed.

RESULTS

Findings from the 25 included primary studies were organized into three intervention design-focused themes. Delivery of culturally-tailored programs (e.g., use of language and interpretive services) were effective in increasing CRC screening. Regarding the method of delivery for FIT, specific strategies combined with mail-out programs (e.g., motivational screening letter) or in-person delivery (e.g., demonstration of FIT specimen collection procedure) enhanced the success of FIT programs. The follow-up reminder theme (e.g., spaced out and live reminders) were generally effective. Additionally, we found evidence of the social determinants of health affecting FIT uptake (e.g., place of residence, race/ethnicity/culture/language, gender and/or sex).

CONCLUSIONS

Findings from this rapid review suggest multicomponent interventions combined with tailored strategies addressing the diverse, unique needs and priorities of the population with no regular healthcare provider or limited access to the healthcare system may be more effective in increasing FIT screening. Decision-makers and practitioners should consider equity and social factors when developing resources and coordinating efforts in the delivery and implementation of FIT screening strategies.

Knowledge and belief of fecal occult blood screening: A systematic review

INTRODUCTION

Colorectal cancer (CRC) is associated with a high incidence and mortality rate. Fecal occult blood test (FOBT) is effective in the prevention of CRC.

OBJECTIVE

This study aimed to assess knowledge and beliefs regarding FOBT-based screening.

METHODS

This study used PubMed, Cochrane Library, MEDLINE Complete, and Web of Science to search for articles. Original full-text studies in English language focusing on knowledge and beliefs of FOBT screening were included.

RESULTS

A total of 32 articles were included. This study indicated that the population in most studies had inadequate knowledge and lacked beliefs toward FOBT-based screening. Most of the extracted studies showed that less than half of the participants had heard of FOBT-based screening. Six studies showed that less than 50% of participants had knowledge of FOBT age. Three studies found that less than 40% of participants were aware of the screening interval. Some participants perceived the benefits of FOBT-based screening, while others perceived many barriers to the test.

CONCLUSION

Participants' knowledge and belief in FOBT-based screening were insufficient. This review highlights the importance of educational programs to increase knowledge and beliefs regarding FOBT-based screening. It is important to include FOBT-based screening in the health care system to promote the secondary prevention of CRC.

Provincial variation in colorectal cancer screening adherence in Canada; evidence from the Canadian Partnership for Tomorrow's Health

Introduction

Although colorectal cancer (CRC) screening program is proven to reduce CRC incidence and mortality, understanding patterns and predictors of suboptimal adherence in screening program requires further investigation in Canada.

Methods

We used self-reported data from five regional cohorts of the Canadian Partnership for Tomorrow's Health (CanPath), namely the BC Generations Project (BCGP), Alberta's Tomorrow Project (ATP), the Ontario Health Study (OHS), Quebec's CARTaGENE, and the Atlantic Partnership for Tomorrow's Health Study (Atlantic PATH). We stratified participants into the following four risk categories: 1) age 50-74 years, 2) family history in a first-degree relative, 3) personal history of chronic inflammatory bowel disease and/or polyps, and 4) co-existence of personal risk and family history. Multivariable logistic regression was used to identify predictors of adherence to the screening guidelines.

Results

Adherence to CRC screening varied considerably between regions, ranging from 16.6% in CARTaGENE to 47.7% in OHS. Compared to the largest cohort OHS, the likelihood of non-adherence to CRC screening was significantly higher in BCGP (OR 1.15, 95% CI 1.11-1.19), the Atlantic PATH (OR 1.90, 95% CI 1.82-1.99) and CARTaGENE (OR 5.10, 95% CI 4.85-5.36). Low physical activity, current smoking, presence of personal risk, family history of CRC significantly reduced the likelihood of adherence to screening recommendations.

Discussion/conclusion

Compared to the national target of ≥ 60% for participation in CRC screening, adherence to regular CRC screening was suboptimal in this cohort of Canadians and varied by region. Further efforts are needed to identify the specific barriers to screening adherence in different provinces and across risk categories.
