Implementing a small media intervention to increase colorectal cancer screening in primary care clinics

Effectiveness of health promotion interventions to increase faecal occult blood test uptake rates among older adults with an average-risk of colorectal cancer: A systematic review and meta-analysis

Objective

This review aims to examine the effectiveness of interventions in increasing faecal occult blood test (FOBT) uptake rates among older adults with an average-risk of colorectal cancer (CRC) and to identify essential components of such interventions based on current evidence.

Methods

Five databases were included in a systematic literature search for studies reporting randomized controlled trials (RCT) and interventions aimed at increasing FOBT uptake rates among average-risk individuals aged 50-75. Review Manager 5.4.1 was used for conducting meta-analyses and subgroup analyses.

Results

A meta-analysis of the 20 included studies demonstrated that health promotion interventions led to significant increases in FOBT uptake rates (odds ratio [OR] ​= ​1.55, 95% confidence interval (CI) ​= ​1.30-1.85; I 2 ​= ​95%). Provision of information, mailing of FOBT outreach, and reminders were identified as core components of promotion interventions to increase FOBT uptake rates. Among the different significant reminder strategies, a digital message (via text) plus telephone calls (automated and navigator-initiated) had a larger effect size than a telephone call alone. In addition, there was no significant evidence that financial incentives were associated with FOBT uptake. Most studies included a diverse mixture of components, but only a few studies utilized theoretical framework-based interventions.

Conclusions

Future studies with rigorous methodologies are warranted to examine the effectiveness and understand the mechanisms of theoretical framework-based multi-component educational programmes aimed at increasing FOBT uptake rates.

The Effect of a Tailored Educational Flyer on Colorectal Cancer Screening Among Rural Residents: Lessons Learned from a Pilot Randomized Trial

Background/Objectives: Stool-based tests, such as the fecal immunochemical test (FIT), have been widely used for increasing colorectal cancer (CRC) screening. Small media, such as printed materials or flyers, are known to be an effective intervention to increase CRC screening by fecal tests. However, more evidence is needed to determine whether such small media are effective in improving screening uptake of a mailed FIT intervention targeted at rural populations in the USA. Methods: In this randomized study, 1230 FIT kits were mailed from July to December 2022 to rural Nebraskans aged 45-74 who were not up to date on CRC screening. Half of the participants (n = 608) also received a tailored, one-page, gender-specific educational flyer created based on focus groups with rural residents. Logistic regression was used to determine predictors of returning the FIT. Results: Study participants were predominantly female (76%), non-Hispanic White (83%), and within the age group of 55-64 (43%). Overall, 192 (15.6%) kits were returned (16.1% from the flyer group; 15.1% from the no-flyer group). However, we found no significant differences between the flyer and no-flyer groups (Adjusted Odds Ratio [AOR]: 1.21; 95% CI: 0.88-1.66). Females (AOR: 1.78; 95% CI: 1.19-6.14) and the oldest (65-74) age group (AOR: 5.03; 95% CI: 2.78-8.47) were more likely to return FIT kits than males and the youngest (45-54) age group. Conclusions: A tailored educational flyer was not effective in improving the CRC-screening-rate-by-mailed-FIT approach for rural populations. Future research should explore the content, timing, and mode of delivery of educational interventions as well as other multi-component strategies to improve screening rates. Public health officials might also consider developing strategies targeted at males and younger (45-54) age groups.

The Effects of Animations and Multimedia Messages on Public Engagement in Precision Medicine: Assessment of Moderation and Mediation

Public participation in precision medicine (PM) research is essential to achieving effective health care but has been impeded by a lack of awareness and basic knowledge. There is a critical need for educational materials that can clearly explain PM to foster involvement. This randomized controlled trial with a posttest-only control group design aims to assess the effects of educational messages delivered through animations relative to live-action videos and leaflets on intentions of involvement in PM research. Knowledge as the moderator and four mediators (engagement, vividness, trustworthiness, and cognitive value) of the intended effects were also evaluated. A total of 326 U.S. adults were sampled from Amazon Mechanical Turk. Among participants with less knowledge about PM, animations produced stronger information-seeking intentions and willingness to participate than leaflets. The effects of three message modalities were not significantly different among average and highly knowledgeable participants. Engagement and vividness mediated the effects of animations relative to two other message modalities. Trustworthiness and cognitive value mediated the effects of animations relative to live-action videos. Overall, animations can be an effective communication strategy to motivate involvement in PM but its effectiveness could decline as knowledge increases. The explanations and implications of the findings were discussed.

Factors associated with colorectal cancer screening in a peer-counseling intervention study in partnership with African American churches

Colorectal cancer (CRC) mortality is 47% higher in African American men and 34% higher in African American women compared to non-Hispanic white men and women. This analysis assessed factors associated with CRC screening among 163 African American participants of a peer-counseling intervention study (2016-2018). In a one-group pre/post-test pilot study, trained Community Health Advisors (CHAs) at 9 African American churches in Los Angeles (LA) promoted CRC screening via one-on-one counseling, print materials and telephone reminder calls. Participants completed telephone surveys 3-6 months after the intervention. We fit bivariate and multivariate mixed effects logistic regression models to assess correlates, including participants' demographic characteristics, access to care, cancer-related knowledge and attitudes and receipt of CHA counseling of (1) discussion of CRC screening with provider and (2) receipt of CRC screening during follow-up. After controlling for gender and education, receipt of CHA counseling (OR 3.77) was significantly associated with discussing CRC screening with a provider during follow-up but not with CRC screening. Instead, a routine check-up in the past 12 months (OR 4.47) and discussion of CRC screening with a provider (OR 3.07) were significantly associated with CRC screening during follow-up. Residence in South LA (OR 0.38) was significantly associated with lack of CRC screening. Findings confirm the important role of health care providers and suggest that residence in South LA constitutes an additional barrier to CRC screening. Further research and additional resources are needed to address disparities in the uptake of CRC screening among African Americans, especially in South LA.
